What Is 5G? Your Guide To The Current Generation Of Wireless Communications

5G Infrastructure Market

5G Infrastructure Market

5G infrastructure refers to the network of macro and small cell base stations with edge computing capabilities required for the functionality of the fifth-generation cellular network technology standard.

While many things are uncertain on the road to 5G, it is easy to imagine new and innovative use cases emerging. To understand how these will change infrastructure requirements, we’ve broken them down into three categories: enhanced mobile broadband, IoT, and mission-critical applications. These use cases require network performance to be 10x the current level across all network parameters as measured by latency, throughput, reliability and scale. To achieve this goal, mobile operators must invest in all network areas, including spectrum, radio access network (RAN) infrastructure, transmission and core networks

Challenges in expanding 5G NR mm Wave network coverage

One of the biggest challenges in broadening 5G NR mm Wave network coverage is the cost of deploying additional mm Wave base stations. The following are some other primary 5G mobile mm Wave problems and how to overcome them:

  • A key aspect of this deployment requires robust backhaul deployments using new wireless backhaul infrastructure that will make mm Wave densification more cost-effective.
  • There will be path attenuation that limits coverage, requiring many small cell deployments; However, analog beamforming helps overcome this path loss.
  • mm Wave requires line of sight (LOS), which can lead to signal propagation limitations. Advanced beamforming and beam tracking help leverage path diversity and reflections.
  • mm Wave only works for stationary use. The solution here is a handover with adaptive beam steering and switching that overcomes deadlocks.
  • A large form factor is required for mm Wave, which is power hungry and has thermal challenges in a small form factor. The solution is modems, RF and antenna solutions to comply with the form factor and thermal limitations imposed by the commercialization of the smartphone.

The costs and investments associated with traditional 2G, 3G and 4G networks, unlike those for 5G, will vary over time and depend on local conditions. Operators have at least two options. The first involves a lean-in strategy where they are prioritizing 5G investments in hopes of accelerating the commercial prospect. The second involves a more conservative approach, delaying 5G investments for as long as possible while existing networks are upgraded.
