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 reliability and allow for significantly greater numbers of devices. 5G, in reality,  is not one, but 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

5G is focused on three specific and significantly different use cases – Enhanced Mobile Broadband, Massive Machine to Machine, and Ultra-reliable low latency communications.

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.

600Mhz

3100-3500Mhz

3700-4200Mhz

27.5-28.35Ghz

37-40Ghz

64-71Ghz

As of mid 2019, the FCC has over 13Ghz of spectrum allocated or under review for licensed 5G use, and another 14Ghz of unlicensed spectrum that will at least in part be used for 5G.

Internationally, each country allocates independently, and thus utilizes different available ranges, but the use cases dictate that there will be some available spectrum within certain general ranges.
