A US-based mobile operator is to deal another blow to Intel's hopes for Wimax by launching 4G mobile network based on Ericsson's Long Term Evolution (LTE) technology next year.
MetroPCS is the latest mobile operator to opt for the Internet Protocol-based LTE technology to support higher data speeds than 3G networks, according to the Financial Times.
Korean handset manufacturer Samsung is to provide MetroPCS with its initial LTE-based smartphone.
Earlier this month, Intel, which has invested heavily in Wimax, slammed mobile operators for not backing the technology for their 4G networks.
Intel chief Paul Otellini accused mobile operators of being self-serving in refusing to move on to Wimax as they are still trying to recoup investments in 3G.
Otellini said Wimax is a viable and proven 4G technology that is being commercially deployed in Japan, Russia and some parts of the US.
But mobile operators are increasing choosing LTE, which is expected to be deployed by most of the world's major network operators over the next five years.
Verizon Wireless, a joint venture between Verizon Communications and the UK's Vodafone group, is expected to begin commercial deployment of its LTE-based network in the US shortly.
