Clearwire's CEO Bill Morrow said the looming 4G standards battle is not a big issue because the company has flexible equipment that can shift from WiMax to Long-Term Evolution technology relatively easily.

The majority of wireless operators around the world have chosen LTE for their 4G upgrade paths, which could be a reason Clearwire's stock has been battered lately. WiMax still has a time-to-market advantage over LTE, but Morrow said the company is well-prepared to shift strategies if it needs to. Many of Clearwire's routers are compatible with WiMax and LTE, and a shift would essentially only require a software update, Morrow said.
