Verizon’s nationwide 5G will only be a “small” upgrade over 4G at first

Verizon Communications CEO Hans Vestberg said that most 5G mobile users will see a "small" upgrade at first, and he stressed the continued relevance of 4G. Vestberg reiterated previous Verizon statements that the biggest improvements will come on millimeter-wave spectrum in the most densely populated and trafficked areas. But millimeter-wave frequencies don't travel as far as low- and mid-band radio waves and are easily blocked by walls and other obstacles, making them unsuitable for nationwide coverage. As such, Vestberg was asked whether consumers will see a noticeable difference between 4G and 5G in areas without millimeter-wave coverage. Vestberg said that customers will eventually see "dramatic improvements," but not in the near term.
