The lines continue to be drawn in the battle over LTE-U. The new technology, which incorporates LTE cell services that operate over unlicensed spectrum to relieve cell site congestion, is being advanced by big players like Verizon, Alcatel-Lucent, Qualcomm, Ericsson, and Samsung. The development of LTE-U, its backers claim, will result in better wireless services for consumers.
Cable companies and the Wi-Fi Alliance are crying foul, however. They feel that since LTE-U doesn’t follow the LBT (Listen Before Talking) protocol, it can ” transmit uninterrupted for an undefined period of time regardless of other network traffic on the channel.” This, the cable companies fear, could lead to interference for Wi-Fi and other technologies that use unlicensed spectrum. The pro-LTE-U side disputes that claim, and notes that Wi-Fi doesn’t always share spectrum fairly, either. In the end, it could be that the FCC will have to sort this all out.
