Sprint was the first official carrier to launch 4G service but opted to go with WiMAX instead of LTE. Unfortunately for Sprint WiMAX ultimately failed due to poor in building coverage and LTE on lower frequency bands took preference by the majority of consumers. Recently Sprint filed a 10G form with the Securities and Exchange Commission stating they’ll shut down 4G WiMAX by the end of 2015. “As a result of the Clearwire Acquisition, we expect to continue to migrate from Clearwire’s wireless broadband technology to LTE technology through the deployment of Network Vision utilizing the 2.5GHz spectrum acquired,” Sprint said in the paperwork, also mentioning they’ll be shutting down 4,300 cell sites that won’t be needed after the switch to 4G LTE.
