T-Mobile US, which notched up its 50 millionth subscriber in 2Q14, has announced that it has deployed voice-over-Long Term Evolution (VoLTE) technology across its entire network footprint. Just two months after introducing VoLTE in Seattle, the cellco claims that the advanced technology now covers 233 million Americans in 325 metro areas, well ahead of its initial schedule.
Further, the carrier has confirmed that its so-called ‘T-Mobile Wideband LTE’ network, which involves the use of at least 15MHz+15MHz of spectrum, is already live in 17 metro areas, with the cellco on target to reach 26 cities by year-end. Wideband LTE delivers theoretical peak down/uplink speeds of 110Mbps/38Mbps.
Meanwhile, the company notes that it has already started equipping its cell sites in preparation for the introduction of its recently acquired 700MHz A block spectrum. T-Mobile notes that it has started field-testing its first 700MHz-compatible devices, with a view to introducing them commercially before the end of the year.
