Verizon announced late last year that it would turn on fixed 5G services in 3-5 cities, including Sacramento, sometime in the second half of 2018. Now, the carrier’s deployment plans are getting slightly clearer.

Specifically, Verizon’s CEO Lowell McAdam told The Seattle Times that Verizon’s mobile 5G service will launch roughly six months after the carrier turns on its fixed 5G service. Those comments are notable because Verizon hasn’t offered too much detail about how it might roll out mobile 5G—although Verizon’s CFO said last year the carrier wouldn’t launch mobile 5G services in 2018.  

Verizon’s fixed 5G services are intended to compete with wired internet services by blasting a 5G connection from a nearby cell site to receivers either outside or inside users’ homes or offices. Mobile 5G, on the other hand, is designed for portable devices like smartphones and tablets.
