T-Mobile US executives blasted AT&T's ambitious 5G plans this week, citing numerous unanswered questions around device availability, spectrum and footprint.
AT&T announced plans to launch mobile 5G by the end of 2018. However, the company's release left out specifics including what markets will be included in the launch and what devices will be compatible with the new capabilities. The latter is a particularly pertinent question as most major chipset vendors - including Qualcomm and Intel - said they expect commercial 5G chipsets to become available in 2019.
