Kenwood was toying around with some LTE handsets at the 2017 IWCE show, they were rebadged Sonim units, if I recall correctly.
Kenwood is still working towards taking more of the market share, and this may be a good move for them. It's certainly a step in the right direction. With LTE taking a larger role in the industry, this makes sense. Will be interesting to see how this plays out in the long run.
