Within the world of 5G, devices communicate with one another via radio waves, which are carved up into sections called frequency bands. These bands, however, vary in speed and coverage.
In this blog, you'll learn about the types of 5G frequency bands, how they differ, and how Trenton's solutions support these bands to enhance computing at the edge.
With the technological landscape becoming increasingly interconnected, the ability to communicate between devices is critical.
Devices communicate via radio waves, which are forms of electromagnetic radiation that transfer data. These radio waves are divided up into frequency bands.
There are three frequency bands: low-band, mid-band, and high-band. Each of these bands has different capabilities (More on that later).
5G frequency bands can be used within private 5G networks to provide the best service depending on the environment and distance from the source signals, helping to eliminate dead zones.
Many materials can reflect or block high-frequency signals, but 5G technology can circumvent this by transmitting across the high-, mid-, and low-band ranges.
5G frequency bands also use frequencies across the three bands to optimize performance and can even use multiple frequencies at the same time.
This, in turn, makes 5G frequency bands more flexible than 3G or 4G bands and, as a result, increases coverage and reliability.
As mentioned earlier, there are three 5G frequency bands: low-band, mid-band, and high-band. Each band provides both outdoor and indoor coverage.
At a high level, low-bands have greater coverage but lower speeds, mid-bands have a balance of coverage and speed, and high-bands have higher speeds but less coverage.
In addition, each band presents opportunities for a service provider to balance between frequency, coverage, quality, latency, and reliability.
Spectrum availability will vary between different countries and regions in terms of bands, amounts, and timing.
Let's take a look at each in a little more detail:
Low-band 5G has a frequency range of 600 MHz to 700 MHz, and it provides coverage across a large area.
But this band also has lower speeds of around 50 Mbps.
High-band 5G can operate at 24GHz and above, providing incredibly fast speeds ranging from 1 Gbps to 10 Gbps.
But this band can only transmit data across short distances, limiting its coverage.
Users across various sectors depend on varying levels of connectivity and speed. This requires different 5G spectrum bands.
To support the needs of different users, network operators use network slicing to create independent, virtual network slices from a single shared physical network.
In addition, spectrum licensing limits activity on any one spectrum band to avoid interference and maximize efficiency.
Let's take a look at use cases for each 5G spectrum band:
Low-band 5G can be used to send small amounts of data from many distributed devices to a network and from a network back to these devices.
This holds especially true for covering wide outdoor spaces and transmitting data deep into an indoor environment.
Low-band 5G is commonly used for monitoring in rural areas and communication between indoor and outdoor machines.
Other use cases include IoT devices, smart cities, logistics, and smart agriculture.
Mid-band 5G can be used to quickly transmit data across large areas, providing a balance between coverage and speed, and it can still be used within both indoor and outdoor environments.
Higher speed means lower latency, which, in turn, means mid-band 5G can handle more data than low-band 5G.
This proves to be especially useful for 5G use cases like enhanced mobile broadband (eMBB) and Ultra Reliable Low Latency Communications as well as autonomous vehicles.
Other use cases include media and entertainment, health, smart cities, and smart agriculture.
High-band 5G offers the fastest data transfer speeds, but the coverage area is very limited. This offers incredibly high performance with low latency, but within a very targeted area.
This proves to be especially useful for artificial intelligence (AI) and edge computing applications, where massive amounts of data need to be processed, analyzed, encrypted, and delivered to users within a matter of seconds.
Other use cases include media and entertainment, manufacturing, automotive, and retail.
No equipment is needed to access 5G frequency bands, as the 5G network automatically switches between bands during transmission.
Additionally, many 5G devices have more than one antenna to support multiple bands.
At Trenton Systems, our 5G-powered high-performance computing solutions, in rack mount or small form factor, support all 5G frequency bands, providing the appropriate amount of coverage and speed based on user needs.
Equipped with increased data transfer rates and low latency provided by 5G connectivity, our systems help enhance applications like C6ISR, JADC2, and SIGINT at the edge in real-time within harsh environments.
This means critical insights can be delivered to military personnel across various domains within a matter of seconds, increasing situational awareness and, as a result, enabling them to effectively detect, track, and engage with enemy threats.
With varying levels of speed and coverage, low-, mid-, and high- 5G frequency bands provide users across the commercial, military, and industrial sectors with the tools they need to tackle complex, demanding workloads in various environments.
These frequency bands can also adapt to performance requirements, as networks can switch between frequencies, and multiple frequencies can be used simultaneously.
Across the multi-domain battlespace, 5G frequency bands give our warfighters the flexibility to quickly adapt to their surroundings and respond to enemy threats.
