"Verizon and Boingo are working together to architect a hyper-dense network designed for large and small indoor spaces as part of Verizon's ongoing 5G network expansions," a Verizon spokesperson said in a statement. Verizon this week made Phoenix, Arizona, the 10 th city in which its 5G Ultra Wideband service is available. Chase Field, the home of Major League Baseball's Arizona Diamondbacks, and Talking Stick Resort Arena, the Phoenix Suns' NBA arena, are among the limited number of landmarks where the service will be available.
