The number of 4G LTE frequency bands is increasing. We are also moving into an era of downlink CA beyond 5 Component Carriers (CC). High Performance UE (+26 dBm) usage is expanding as is LAA (Licensed Assisted Access) in unlicensed 5 GHz spectrum enabling small cell densification.
The U.S. is about to embark on 3.5 GHz in shared spectrum, Citizens Broadband Radio Service (B48 CBRS), which will enable expansion of private LTE networks and neutral hosts. 2018 will bring the rollout of the FirstNet B14 LTE system for first responders, which will be available for usage in consumer cell phones where spare capacity exists.
3GPP has approved the first 5G New Radio (New Radio) Specification (38.101) using an LTE anchor in a Dual Connect configuration of LTE and 5G systems, called non-standalone (NSA NR). 5G will initially use FR1 (Frequency Range 1, <6 GHz) bands n28, n41, n71, n77, n78 and n79; then mmWave FR2 (Frequency Range 2, >6 GHz) band n257 (28 GHz); and followed by n260 (39 GHz).
