Sprint used the 2.5 GHz spectrum for its WiMAX network in 2010. This frequency forced the installation of four times the number of towers compared to 800 MHz networks because of a 3-mile signal range. The WiMAX hardware demanded high levels of power. The HTC EVO 4G experienced thermal issues and battery depletion. The industry crushed WiMAX by adopting LTE as the standard. T-Mobile acquired Sprint in 2020 for its 2.5 GHz spectrum.#Sprint#WiMAX#4G#LTE#tmobile
