Theres multiple duelling companies just in the class license antenna space. Like not even emitters, just designing compatible antennas for other peoples telco products.

Theres the whole thing where all the wigig chips that dell binned got upcycled into a companies flagship rf product.

Cambium v Ubiquiti has been an ongoing contest. Add Mikrotik in for good measure.

RF Elements is always trying to sell me something new.

Aviat has bought out NEC's famous flagship RF line, at least in terms of US distribution.

Theres enough happening.
