One year after the presentation of the “GigabitStrategy” for the expansion of high-speed Internet, many projects have been completed. The expansion of fiber optic connections is progressing. However, only a minority of households already use fast access.
According to the Digital Ministry, the expansion of fast Internet connections in Germany is progressing rapidly. Last year, around four million additional households were connected to the fiber optic network, said Digital and Transport Minister Volker Wissing (FDP) at the “One Year of Gigabit Strategy” celebration.
Every fourth household with a fiber optic connection
One year after the launch, the company has come closer significantly to its goal of providing comprehensive and high-performance gigabit coverage, said Wissing. According to him, by the end of 2022, around one in four households in Germany had a fiber optic connection .
The expansion of high-speed networks is also progressing in mobile communications. Within a year, coverage of the fast fifth generation(5G) mobile network increased to 87 percent of the area in Germany, corresponding to an increase of 22 percentage points.
A comprehensive, efficient, and reliable supply of gigabit networks is the basis for successful digitization and the future viability of Germany as a business location, Wissing told the DPA news agency. “In the past twelve months, we have succeeded in triggering additional momentum in expanding fiber optic and mobile communications.” His ministry approach is to bring all those involved to the table and tackle the ambitious goals together.
Demand in households is still lagging behind
Fiber optic access is a technology that runs fiber optic cables right into the home or basement (“Fiber to the Home”/FTTH or “Fiber to the Building”/FTTB). The Internet connections are better than those via telephone cable (VDSL) or television cable.
However, the supply increasing of connections in households is higher than demand: only a quarter of households where FTTH/FTTB is available have activated the fiber optic connection, according to a study by Dialog Consult commissioned by the internet industry association VATM. The other three -quarters do not have the connection. This is probably mainly due to the relatively high prices for fiber optic contracts.
By the end of 2025, fiber optics in every second household
A year ago, the traffic light coalition presented a”gigabit strategy”, a package of measures comprising 100 projects, the main aim of which is to simplify and accelerate approval procedures for network expansion. In the paper, the federal government has set itself the goal of providing fiber optics to homes and the latest mobile communications standard by 2030 “wherever people live, work or are on the move”.
As a first step, the coalition wants to push ahead with the expansion so that at least every second household can use fiber optics by the end of 2025. Of the 100 planned measures, only 39 points are shown as open on the website of the Digital Ministry, 35 as “in progress” and 4 as”not yet started”. 32 have therefore been completed. The remaining 29 measures are ongoing.
Among the measures, Wissing highlighted the adoption of DINstandard 18220, which is intended to facilitate the alternative cable laying method of trenching. In trenching, fiber optic cables are not laid in deep trenches that have to be laboriously excavated, but in much less deep slots that are milled into streets and sidewalks.
Industry sees broadband expansion as a marathon
Srini Gopalan, head of Telekom Deutschland, said that broadband expansion is a marathon that requires a lot of patience. However, there are hurdles along the marathon route that need to be cleared. Markus Haas, CEO of Telefónica Deutschland, said the expansion targets are not yet ambitious enough. The full expansion must be completed before 2030.
To achieve this, approval procedures must be further simplified.
Gopalan, Haas, and the new Vodafone Germany boss Philippe Rogge spoke out in favor of the large Internet companies such as Google, Netflix, and Amazon contributing to the expansion costs. Ralph Dommermuth, the head of United Internet AG, on the other hand, said that the industry was already making good money and did not need to ask the Internet companies to pay. Customers who like to watch Netflix would also have to pay for the network connection required for it.
This is where you can find an explanation of 5G technology—how it functions, its importance, and how it is revolutionizing global connectivity and communication.
5G represents the fifth generation of mobile networks and is a new standard in wireless technology following 1G, 2G, 3G, and 4G networks. It is designed to create a new network connecting virtually everything and everyone, including machines, objects, and devices.
The purpose of 5G wireless technology is to provide higher multi-Gbps peak data speeds, extremely low latency, increased reliability, massive network capacity, improved availability, and a more consistent user experience for a larger number of users. These enhancements enable new user experiences and facilitate connections across diverse industries.
Although 5G is not owned by any single company or individual, several companies in the mobile ecosystem are contributing to its development. Qualcomm has been instrumental in inventing the foundational technologies that drive the industry forward and form 5G, the next wireless standard.
We are part of the 3rd Generation Partnership Project (3GPP), the organization responsible for defining the global specifications for 3G UMTS (including HSPA), 4G LTE, and 5G technologies.
3GPP is instrumental in driving essential innovations across all aspects of 5G design, from the air interface to the service layer. Other 3GPP 5G members include infrastructure vendors, component/device manufacturers, mobile network operators, and vertical service providers.
5G is based on OFDM (Orthogonal frequency-division multiplexing), a method of modulating a digital signal across multiple channels to reduce interference. 5G employs the 5G NR air interface alongside OFDM principles. It also utilizes wider bandwidth technologies such as sub-6 GHz and mmWave.
Similar to 4G LTE, 5G OFDM operates based on the same mobile networking principles. However, the new 5G NR air interface can further enhance OFDM to provide greater flexibility and scalability, expanding 5G access to a wider range of users and applications.
5G will expand into new spectrum resources, operating in both lower bands (e.g., sub-6 GHz) and mmWave (e.g., 24 GHz and higher), offering extreme capacity, multi-Gbps throughput, and low latency.
The design of 5G is not only focused on providing faster, improved mobile broadband services compared to 4G LTE, but also on expanding into new service areas such as mission-critical communications and connecting the massive IoT. This is made possible through new 5G NR air interface design techniques, such as a new self-contained TDD subframe design.
Prior generations of mobile networks include 1G, 2G, 3G, and 4G.
First generation – 1G
1980s: 1G provided analog voice.
Second generation – 2G
Early 1990s: 2G introduced digital voice (e.g. CDMA- Code Division Multiple Access).
Third generation – 3G
Early 2000s: 3G introduced mobile data (e.g. CDMA2000).
Fourth generation – 4G LTE
2010s: 4G LTE ushered in the era of mobile broadband.
1G, 2G, 3G, and 4G have led to the development of 5G, which aims to provide more connectivity than ever before.
5G is an enhanced, more capable air interface designed to enable next-generation user experiences, support new deployment models, and offer new services.
With its high speeds, superior reliability, and minimal latency, 5G will push the mobile ecosystem into new frontiers. 5G will impact every industry, making safer transportation, remote healthcare, precision agriculture, digitized logistics, and more a reality.
There are several reasons why 5G is superior to 4G:
- 5G is significantly faster than 4G.
- 5G has more capacity than 4G.
- 5G has significantly lower latency than 4G.
- 5G is a more capable unified platform than 4G.
- 5G utilizes spectrum more efficiently than 4G.
- 5G is a unified, more capable platform compared to 4G.
While 4G LTE focused on delivering much faster mobile broadband services than 3G, 5G is designed to be a unified, more capable platform that not only enhances mobile broadband experiences but also supports new services like mission-critical communications and the massive IoT. 5G can also natively support all spectrum types (licensed, shared, unlicensed), a wide range of deployment models (from traditional macro-cells to hotspots), and new ways to interconnect (such as device-to-device and multi-hop mesh).
5G utilizes spectrum more effectively than 4G.
Designed to maximize the utilization of available spectrum across various regulatory paradigms and bands, 5G encompasses low bands below 1 GHz, mid bands from 1 GHz to 6 GHz, and high bands known as millimeter wave (mmWave).
- 5G is faster than 4G.
- 5G can deliver significantly higher speeds than 4G, offering up to 20 Gigabits-per-second (Gbps) peak data rates and 100+ Megabits-per-second (Mbps) average data rates.
- 5G has more capacity than 4G.
- 5G is engineered to support a 100x increase in traffic capacity and network efficiency.
- 5G has less latency compared to 4G.
- 5G has significantly reduced latency for quicker, real-time access, with a 10-fold decrease in end-to-end latency down to 1ms.
- The global economy is being boosted by 5G.
- The global economic output is estimated to be $13.1 trillion.
- There will be 22.8 million new job opportunities.
- About $265 billion is expected to be invested in global 5G CAPEX and R&D annually over the next 15 years
Based on a comprehensive 5G Economy study, it is projected that by 2035, the full economic benefits of 5G will likely be experienced worldwide, leading to support for various industries and potentially enabling up to $13.1 trillion worth of goods and services.
This impact is much larger compared to previous network generations. The development requirements for the new 5G network are also extending beyond the traditional mobile networking players to industries such as the automotive industry.
The study also uncovered that the 5G value chain (including OEMs, operators, content creators, app developers, and consumers) could potentially support up to 22.8 million jobs, which is more than one job for every person in Beijing, China. Moreover, many emerging and new applications will be defined in the future, and only time will reveal the full “5G effect” on the economy.
5G is engineered to perform various functions that can revolutionize our lives, including offering faster download speeds, low latency, and increased capacity and connectivity for billions of devices—particularly in the realms of virtual reality (VR), the Internet of Things (IoT), and artificial intelligence (AI).
With 5G, individuals can access new and enhanced experiences, for instance, nearly instantaneous access to cloud services, multiplayer cloud gaming, shopping with augmented reality, real-time video translation and collaboration, and more.
Generally, 5G is utilized across three main types of connected services, comprising enhanced mobile broadband, mission-critical communications, and the massive IoT. A key feature of 5G is its design for forward compatibility—the flexibility to support future services which are currently unknown.
Enhanced mobile broadband
Apart from enhancing our smartphones, 5G mobile technology can introduce new immersive experiences such as VR and AR with faster, more consistent data rates, lower latency, and lower cost-per-bit.
Mission-critical communications
5G can facilitate new services that can revolutionize industries with ultra-reliable, available, low-latency links, like remote control of critical infrastructure, vehicles, and medical procedures.
Massive IoT
5G is intended to seamlessly connect an enormous number of embedded sensors in virtually everything through the capability to scale down in data rates, power, and mobility, offering extremely lean and cost-effective connectivity solutions.
The average consumer is projected to consume approximately 11 GB of data per month on their smartphone in 2022. This growth is driven by the exponential rise in video traffic, as mobile is increasingly becoming the primary source of media and entertainment, as well as the substantial expansion in always-connected cloud computing and experiences.
4G completely transformed how we access information. Over the past decade, there have been significant advances in the mobile app industry, encompassing services such as video streaming, ride sharing, food delivery, and more.
5G will extend the mobile ecosystem to new industries, contributing to cutting-edge user experiences such as boundless extreme reality (XR), seamless IoT capabilities, new enterprise applications, local interactive content, and instant cloud access, among others.
With high data speeds and superior network reliability, 5G will have a profound impact on businesses. The benefits of 5G will enhance business efficiency while also providing users with faster access to more information.
Depending on the industry, some businesses can fully leverage 5G capabilities, particularly those requiring the high speed, low latency, and network capacity that 5G is designed to provide. For example, smart factories could employ 5G to operate industrial Ethernet to help enhance operational productivity and precision.
Smart cities could utilize 5G in numerous ways to enhance the lives of their residents, primarily providing greater efficiencies such as increased connectivity between people and objects, higher data speeds, and lower latency than ever before in areas like automotive safety, infrastructure, VR, and entertainment.
5G is engineered to deliver peak data rates of up to 20 Gbps based on IMT-2020 requirements. Qualcomm Technologies’ flagship 5G solutions, the Qualcomm® Snapdragon™ X65 is designed to achieve up to 10 Gbps in downlink peak data rates.
However, 5G offers more than just speed. Besides higher peak data rates, 5G is engineered to provide much greater network capacity by venturing into new spectrum, such as mmWave.
5G can also offer significantly lower latency to provide a more immediate response and can ensure an overall more consistent user experience so that data rates remain consistently high, even when users are on the move.
The new 5G NR mobile network is supported by a Gigabit LTE coverage base, offering widespread Gigabit-class connectivity.
Similar to 4G LTE, 5G also uses Orthogonal frequency-division multiplexing (OFDM) and will function according to similar mobile networking principles. However, the new 5G NR (New Radio) air interface will improve OFDM to provide greater flexibility and scalability.
5G will not only provide faster, improved mobile broadband services compared to 4G LTE, but it will also extend into new service areas, such as mission-critical communications and connecting the massive IoT. This is made possible by many new 5G NR air interface design techniques, including a new self-contained TDD subframe design.
5G can revolutionize home internet service by offering a wireless modem alternative to existing cables. Internet Service Providers (ISPs) can now serve customers using 5G infrastructure, making the coverage, performance, and deployment flexibility of 5G a compelling backhaul alternative to fiber, DSL, or cabled solutions.
Is 5G available now?
A: Yes, 5G is already accessible today, and global operators began launching new 5G networks in early 2019. Additionally, all major phone manufacturers are introducing 5G phones. Furthermore, even more individuals may soon have access to 5G.
5G has been deployed in 60+ countries and is continuing to expand rapidly. The rollout and adoption of 5G are much faster than that of 4G. Customers are highly enthusiastic about the high speeds and low latencies. Moreover, 5G offers mission-critical services, enhanced mobile broadband, and massive IoT capabilities. While it’s difficult to predict when everyone will have access to 5G, significant momentum in 5G launches has been observed in its first year, and more countries are expected to introduce their 5G networks in 2020 and beyond.
Affordable 5G phones are already available. In fact, 5G is now offered across all tiers of the current Qualcomm Snapdragon mobile platforms, from 8- to 4-series, making 5G accessible to over 3.5 billion smartphone users worldwide.
Do I need a new phone if I want 5G?
A: Yes, you’ll need to acquire a new smartphone that supports 5G to utilize the network. For example, smartphones powered by the Snapdragon 5G Mobile Platforms are 5G compatible.
Numerous new mobile phones are available that are designed to support 5G, and multiple carriers around the world support the 5G wireless network. As the 5G rollout progresses, more smartphones and carrier subscriptions will become available as 5G technology and 5G compatible devices become more common.
5G is already here, and new 5G NR devices and networks are being launched at a rapid pace, significantly faster and more globally than LTE during its initial year of commercial deployment. This is just the beginning. Next year, 5G is expected to expand to more smartphone tiers and reach more consumers, expanding to new global markets and device classes like the always-connected PC.
On the network side, both sub-6 GHz and mmWave 5G coverage will continue to grow, thanks to new 5G spectrum being made available through auctions and dynamic spectrum sharing (DSS). DSS will lead to even broader 5G coverage in lower bands and enable direct migration from existing non-standalone (NSA) networks to standalone (SA) networks.
In 2019, the focus was on commercializing 5G NR enhanced mobile broadband (eMBB) and fixed wireless access. It’s an interesting time to consider how we got here and what’s next for 5G.
One frequent question is: “why did we need 5G?” Its primary objective was to meet the global demand for better mobile experiences. Additionally, it aimed to create a unified platform to enable new services and address new industries across a range of spectrum types. Ongoing research and technological advancements allow 5G to deliver capabilities that were not possible when 4G was developed.
For example, 5G introduces a more efficient and unified TDD design with faster turnaround that can scale to various deployment scenarios and spectrum use, including low sub 1 GHz, mid 2-7 GHz, and high mmWave bands like 28 GHz, 39 GHz, and 60 GHz — even considering designs for higher frequencies beyond 100 GHz. Furthermore, 5G’s flexible architectural framework allows for new inventions and extends 5G’s reach.
5G is an innovation platform for the next decade, and technology boundaries will continue to be pushed to address new market needs and support future services that are not yet defined. If historical trends continue, the next-generation technology leap after 5G will occur in approximately 10 years’ time, and fundamental research continues to progress the industry toward new technological breakthroughs. Regardless of whether it’s called 6G or something else, Qualcomm Technologies will continue to lead the way.
What is the function of technologies that intersect with 5G?
As well as the specifics of 5G technology advancement, it’s essential to consider the development of other significant technologies that intersect with 5G, particularly the role of artificial intelligence (AI). Currently, we are enabling various power-efficient on-device AI inference use cases, such as computer vision and voice recognition. Although AI is typically cloud-centered, we anticipate AI to become increasingly distributed in the future, with lifelong on-device learning, offering benefits such as enhanced personalization and improved privacy protection.
The advanced capabilities of 5G make it well-suited for connecting distributed on-device AI engines and enabling them to be further enhanced by the edge cloud — a concept referred to as the wireless edge.
Due to economic and performance tradeoffs, we see compelling opportunities to distribute functions like processing or AI over 5G, which can drive technological advancements to unlock new possibilities for low-latency services in the 5G era.
5G is the fifth generation technology standard for broadband cellular networks, which cellular phone companies began deploying globally in 2019. It follows the 4G networks, which currently provide connectivity to most cellphones.
5G offers faster download speeds, reduced latency time, as well as higher connection density of devices per km2. This increased performance will accelerate the development of many new and existing technologies.
Many individuals find the transition from 3G to 4G, and now to 5G, perplexing and do not comprehend the reasons behind these changes. This problem of EUC will address some of this confusion and deliberate on several ways that new generations of cellular broadband networks and devices are significant to practically every industrial and commercial business, as well as many aspects of our everyday lives.
What is the infrastructure of 5G?
5G, which is a popular topic worldwide, is the fifth generation technology standard for broadband in the telecommunications industry and the successor to the 4G networks that currently provide connectivity to most cellphones. It is projected that by 2025, there will be over 1.1 billion subscribers to 5G networks worldwide, according to the GSM Association (Global System for Mobile Communications).
Similar to its predecessors, 5G networks are cellular networks that divide the service area into small geographical areas called cells. All 5G wireless devices in a cell are connected to the internet and telephone network by radio waves through a local antenna in the cell area.
Standalone and non-standalone 5G network infrastructure
Non-standalone infrastructure (NSA) partly relies on existing 4G LTE infrastructure but also incorporates some new technology like 5G New Radio (NR). According to 3GPP standards, NSA architecture involves the 5G RAN and the 5G NR interface working in conjunction with existing LTE infrastructure and core network. The 5G standard also specifies that while only LTE services are supported, the network has the capabilities offered by 5G NR, such as lower latency.
Non-standalone (NSA) network architecture dominated the market in 2020, with a revenue share of over 92.9%, as reported by Grand View Research, Inc. This is due to the early rollout of the non-standalone network worldwide, which is typically deployed in integration with the existing LTE infrastructure. Several major service providers, including AT&T, Verizon, and China Mobile, have implemented 5G NSA network models for basic use.
Standalone infrastructure is a 5G network that operates independently of LTE networks and has its own cloud-native network core connected to the NR. It is expected that network carriers will leverage standalone infrastructures after transitioning through an NSA infrastructure. Utilizing an NSA approach enables carriers to provide experiences similar to 5G while they build out the necessary physical infrastructure of a 5G network.
As per the 3GPP Release 15, the standalone deployment option consists of user equipment, the RAN (including the NR), and the 5G core network. The 5G core network utilizes a service-based 5G architecture framework with virtualized network functions.
5G network tower structure
Macrocells are the traditional cell towers that cover extensive areas. In a 5G network, network functions that are usually hardware-based become virtualized and run as software. While 5G networks are progressing and becoming more self-sustaining, most carriers will continue to utilize existing 4G LTE radio access networks (RANs) along with numerous new antennas. This allows carriers to transition from 4G to 5G by offering enhanced services while constructing the new physical infrastructure.
5G infrastructure equipment
5G infrastructure equipment is mainly comprised of: Radio Access Network (RAN); a core network that provides various services to connected customers; a backhaul that links the backbone and the edge networks; and a transport system that connects a 5G RAN and the core network. The backhaul and transport network include fiber optics or microwave antennas.
In the equipment sector, RAN was the primary component of the 5G infrastructure market, holding a 47.6% share in 2020, according to Grand View Research, Inc. This was due to the extensive deployment of 5G RAN with multiple small cells and macrocell base stations worldwide.
The trend of deploying virtual and centralized RAN is rapidly gaining traction among network service providers to reduce overall infrastructure costs and network complexities. Moreover, the use of Software-Defined Networking (SDN) technology to enhance the operational efficiency of virtual RANs is expected to significantly contribute to segment growth from 2021 to 2028.
Frequency band categorizations
Sub-6 GHz bands are utilized for frequencies transmitted from cell phone towers below 6GHz. The sub 6GHz spectrum is favored for early deployment of 5G networks worldwide. It utilizes an available part of the spectrum below the 6GHz range and can support higher bandwidth compared to LTE frequency bands. Sub-6GHz dominated the 5G infrastructure market with a share of over 91% in 2020.
mmWave frequency bands are high-band frequencies that offer increased bandwidth capacity and very low latency. These spectrum bands will be particularly beneficial in applications requiring ultra-reliable connectivity, especially in remote patient surgeries and Vehicle-to-Vehicle (V2V) connectivity.
The onset of Covid-19 significantly hindered the rollout of 5G infrastructure. The pandemic led to disruptions in testing and trials necessary for validating the performance and stability of 5G standalone networks. Additionally, the pandemic resulted in decreased exports of telecom equipment for 5G New Radio Technology (NR) from the US, China, and other countries to the global market.
Recovery and innovation
Despite the pandemic, the ongoing focus on enhancing communications for energy monitoring and management, in conjunction with the necessity to gain better control over the energy generation and distribution network, is anticipated to drive the deployment of 5G infrastructure in the next 7 years. Numerous industry reports indicate that the global 5G infrastructure market was valued at nearly 3 billion USD in 2020 — and is projected to expand at a compound annual growth rate (CAGR) with growth estimates ranging from 49.8% to 71.2% from 2021 to 2028.
The rapidly increasing industrial digitalization has created a new revenue stream for service providers worldwide. The growing demand to establish continuous communication among industrial applications — such as collaborative/cloud robots, automated guided vehicles (AGVs), wireless cameras, and others — is expected to drive growth in the industrial segment for years. The need to provide uninterrupted connectivity between machines in manufacturing processes increases the demand for ultra-reliable high-frequency, low-latency connectivity.
The deployment of 5G infrastructures is expanding in government and public safety institutions due to the established need for quick communication with first responders during emergencies. Given the ongoing pandemic, the demand for next-generation, high-speed networks is projected to surge.
Substantial growth is expected in the energy sector due to the growing necessity for high-speed internet connectivity across energy generation and distribution applications. Moreover, the increasing demand to provide improved connectivity to ships and vessels for efficient remote monitoring is anticipated to drive the adoption of 5G technology and related infrastructure in the transportation and logistics sector.
The healthcare industry is beginning to emphasize the importance of concepts such as remote diagnosis, treatment, and surgeries for patients. This implies that the delivery of data and connectivity during remote patient surgeries must be reliable and consistent. The next-generation 5G technology and related infrastructure are expected to contribute to market growth in the healthcare industry in the coming years.
Providing high bandwidth services to individuals, businesses, and sectors
A significant change and an advantage of the new 5G networks is their greater bandwidth, resulting in higher download speeds — potentially reaching 10 gigabits per second (Gbit/s). With increased bandwidth, the 5G networks will serve as general internet service providers for laptops and desktop computers, competing with existing ISPs like cable internet. Furthermore, the increasing need for improved bandwidth connectivity with minimal latency for various mission-critical applications — such as precise manufacturing, medical diagnostics and surgery, vehicle-to-everything (V2X), drone connectivity, and numerous other applications — will contribute to the growth of the market.
5G technology will enhance user experience, offering Ultra-High Definition (UHD) video, seamless video calling, as well as Virtual Reality (VR) and Augmented Reality (AR) for gaming. 5G will enable the development of new applications in the Internet of Things (IoT) and enhance machine-to-machine connectivity. 4G mobile phones are not compatible with the new networks, which require 5G-enabled wireless devices. There are various 5G-enabled mobile phones available from your communication service providers today.
Key communication service providers worldwide are making substantial investments to secure low and mid-band frequencies and deliver high bandwidth services to individuals, businesses, and sectors. Recently, governments of key nations such as the US, China, Japan, and South Korea have allocated sub-6 GHz frequencies to provide high-speed internet services in their respective countries.

What is 5G technology?
5G technology represents the fifth generation of mobile cellular communication, facilitating faster sharing and transfer of information than ever before. It also introduces new opportunities for connectivity and connected devices, including the internet of things (IoT) and virtual reality.
Like earlier generations of wireless technologies, 5G serves as a method for connecting individuals through the internet and cellular networks regardless of distance—from short ranges to several miles apart.
What are advantages of 5G over a 4G network? Is 5G better than 4G?
5G is reliable and utilizes the same cellular principles established in 4G, 3G, 2G, and 1G, yet it surpasses 4G due to numerous improvements, such as enhanced data rates, connectivity among vehicles, and interconnectivity between devices. With 5G, a wide range of connectivity is possible—linking everything from automobiles to homes and even coffee shops or entire cities.
Is 5G faster than 4G?
5G represents a natural advancement from 4G and 3G and is distinct from previous generations. It offers higher data rates and additional methods for connecting devices. In simpler terms, 5G is indeed faster than 4G and older networks.
How does 5G technology work?
5G connects us through various mechanisms.
A smartphone and a 5G base station establish a wireless link, which occurs over a frequency band—similar to what most are familiar with regarding FM or AM radio. However, 5G benefits from the availability of several new frequency bands specifically designated for 5G access.
Starting in 2011, the FCC began conducting “frequency auctions” to allow companies access to those frequency bands across the United States. These allocated frequency bands are known as “mid-band frequencies.”
These frequency bands are transformative for 5G because 4G and 3G never had the option of using them. They possess sufficient frequency capacity to accommodate the higher data rates users expect—be it for streaming video or experiencing virtual reality on their devices. This enhances the capabilities of 4G technology, making 5G an evolutionary leap and a significant innovation simultaneously. – Alex Wyglinski, WPI Professor of Electrical & Computer Engineering
5G also operates through another technology called millimeter wave, which utilizes a different set of frequency bands. 4G and 3G did not leverage these bands, which can achieve exceptionally high data rates—gigabits per second—equivalent to transmitting a CD or DVD’s worth of data within seconds. However, the range of millimeter wave is limited.
What is 5G supposed to do?
You might be curious about the purpose of 5G and its necessity; among other technological advancements, 5G is intended to be a primary catalyst for the idea of “smart cities.” Smart cities are areas with near-total 5G connectivity, where almost everything—including residences, office buildings, and streets—will be integrated into the 5G network.
5G also presents the potential to eliminate the requirement for traffic lights, which could help reduce traffic congestion. If all autonomous vehicles are linked via 5G, one car could be instructed to accelerate while those in the opposite direction of travel at an intersection could be advised to decelerate, allowing for fluid movement without stops.
Additionally, 5G could enhance the comfort and efficiency of your home without needing to touch the thermostat by turning it into a smart building.
What is 5G good for? What problems will 5G solve?
5G excels in processing data, gathering sensor information, and interacting with the physical world, connecting them to computing systems that analyze this information and produce actions for devices.
5G addresses the challenge of providing seamless connectivity with higher data rates capable of supporting activities like video streaming, virtual reality, and augmented reality on smartphones. It has the capability to link sensor data with the physical environment, interfacing that with computing technology that processes the data and disseminates it to various devices. Ultimately, 5G technology facilitates the effortless exchange of information and the execution of coordinated tasks, services, and applications aimed at enhancing the quality of life in numerous sectors, including education, commerce, transportation, national defense and security, healthcare, and entertainment.
What are the disadvantages of 5G?
One downside of 5G relates to the existence of multiple wireless systems sharing the same frequency band. This issue is termed spectrum coexistence. The airline sector has expressed concerns regarding the construction of 5G towers near airports and how such spectrum coexistence may disrupt navigation radio altimeters. Nonetheless, air travel might not be the only industry affected; as more frequency bands become available, similar complications could arise with other wireless and radio applications.
There is also the possibility of disappointment regarding 5G; since telecommunications companies have invested heavily in 5G, they need to see a return on their investment.
Where is 5G currently available and in use?
5G will be accessible in all areas where 4G is present. It is being implemented in numerous cities nationwide. Cities with higher population densities received initial access, while rural regions may experience uneven coverage. Residents in less populated areas might face elevated subscription costs if they want to utilize 5G technology.
What distinguishes 4G from 5G?
The main distinction between 4G and 5G is that 4G has limitations—it lacks the capacity for IoT and millimeter wave technology. Data rates are lower with 4G, and it isn’t supported by the new frequency bands sold at FCC auctions.
In simple terms, 5G offers substantial improvements over 4G due to its enhanced capabilities and broader application range. Additionally, to access 5G, a new phone is necessary. However, retaining a 4G phone will still allow it to function on a 5G network, but the user will not experience the 5G speeds or full connectivity.
5G opens doors for technological progress
5G facilitates numerous future opportunities for technological growth, such as the internet of things (IoT). The internet of things encompasses a range of devices that receive, process, and transmit data over the internet and can be controlled remotely without requiring a cell tower. Whether using a computer, laptop, smartphone, tablet, smart TV, game console, or any internet-connected device, you are already utilizing this technology.
5G enables IoT to reach its maximum connectivity potential by allowing low-cost sensors to be positioned nearly anywhere, connecting them to a network. For example, IoT will allow your refrigerator, toaster, thermostat, car, laptop, phone, and home security camera to be linked through a 5G network.
“Now, rather than just humans having connectivity, everything becomes interconnected, and that information will be incredibly powerful,” stated Wyglinski.
What advantages does 5G provide for consumers?
Beyond the internet of things, 5G presents many opportunities for consumers, such as enhanced location services, especially for self-driving cars and mobile phone apps, in addition to virtual reality. 5G also introduces a new type of sensor data. For instance, an autonomous vehicle can now receive 5G information about the location of every other vehicle on the road—both autonomous and human-driven. All that’s needed is a human with a cell phone in their pocket to collect data on the vehicle’s position.
Consumers will notice changes in how they connect to the 5G network due to its greater data processing capabilities, resulting in faster mobile internet and improved internet connectivity.
Concerns regarding 5G
There are concerns related to 5G, including possible privacy invasions and issues tied to cyber security.
5G increases connectivity and the ability to track individuals much more extensively. Innovations in 5G could also render it more vulnerable to cyber attacks. Given that 5G is more affordable, connected, and capable, if a hacker were to exploit a weakness in 5G, they could potentially access billions of devices. However, these vulnerabilities can be addressed. “The best way to secure your devices on 5G is similar to how we protect our computers today, using security software and updates,” according to Wyglinski.
Governments must also consider the challenges associated with 5G. A determined and technologically adept adversary could take advantage of the connectivity offered by the 5G network to engage in malicious actions against officials, in both virtual and physical domains.
The federal government is already taking measures to ensure national safety during the transition to 5G by establishing semiconductor manufacturing facilities in the U.S. and developing private 5G networks for important government offices such as the Department of Defense.
Another issue with 5G is that the infrastructure must be updated for it to achieve its full connectivity potential.
Why is 5G significant?
5G is crucial because of the enhanced connectivity it offers—bringing smartphones, smart appliances, vehicles, and IoT devices onto the 5G network.
The future of 5G and its impact on our lives
Currently, many of us rely on Bluetooth, Wi-Fi, and cell phone services, but in the near future, our ovens, refrigerators, heating systems, home lighting, and garage doors will all be linked through 5G. To utilize the 5G network on your smartphone, you will need to upgrade to a 5G-enabled device.
This vision of a 5G future might seem like science fiction, but it’s an impending reality that ushers us into a hyper-connected world.
I believe younger generations will anticipate even greater connectivity. Gen Z is highly interested in multimedia use and sharing aspects of their lives on social media. Transforming those sharing experiences into a constant engagement requires a robust network.
