5G - The next generation of Mobile Broadband

The 5th generation of mobile technologies – 5G, is a significant step beyond 4G LTE networks in multiple aspects. 5G was defined to reduce latency, increase bandwidth, increase reliablity and allow for significatly greater numbers of devices. 5G is actually a number of technologies, defined by 3GPP as “5G NR” (New Radio) and SMARTER (Study on New Services and Markets Technology Enablers), and by ITU with IMT-2020.  

 The 3 use cases of 5G 

Enhanced mobile broadband (eMBB)– Higher data rates, Higher capacity capacity and connectivity expansive area.  This is the what most consumers would expect 5G to be, comparing to the common usage of 4G.

Massive machine to machine communications or massive Machine Type Communication (mMTC) – IOT … millions of devices, low power, low bandwidth.

Ultra-reliable low latency communications (URLLC) –vehicle to vehicle communications, autonomous driving, telesurgery – anything that needs millisecond type latency, and near zero loss. This is the Tactile Internet.

5G Spectrum

5G has been allocated (and continues to be allocated) spectrum in a number of ranges, low, mid and high frequencies, because of the variety of use cases. In the US, there are 3 major areas.

Low

600Mhz

Mid

3100-3500Mhz

3700-4200Mhz

High

27.5-28.35Ghz

37-40Ghz

64-71Ghz

Each country allocates has different ranges available, but the use cases dictate that there will be some available spectrum across similar ranges.
