Wi-Fi Alliance Repeats Push for Industry-Crafted LTE-U Coexistence Standards

The FCC's best route to LTE-U/Wi-Fi coexistence is by watching and encouraging industry-led progress toward that goal, the Wi-Fi Alliance said in an ex parte filing posted Friday in docket 15-105. The group, which earlier this month put out its own suggested guidelines on how the two can coexist in the same spectrum (see 1511040059), has said the agency should monitor that coexistence development and step in on coexistence issues only if necessary. "I hope we have stepped in on it," FCC Chairman Tom Wheeler said Thursday after the agency's November meeting. "I've said to [LTE-U and Wi-Fi industry representatives], 'Folks, you've got to come together and resolve this in a broad-based standard.' It appears the House subcommittee has done the same. This is the way things ought to be taken care of. There are two things that characterize unlicensed spectrum. One, it's the innovation band; it's where all kinds of new innovations happen. And you want to make sure that in fact continues. The second is, it's the 'everybody respects everybody else' band. And we want to make sure both of those are happening. And the way that can be done is by a broad-based development of commonly agreed-to standards that meets both of those criteria." LTE-U backer Verizon "agrees," Patrick Welsh, assistant vice president-regulatory affairs, told us Friday in an email. "We are actively working with the Wi-Fi Alliance to develop coexistence guidelines for LTE-U." And in a statement, fellow LTE-U advocate Qualcomm said "proponents of LTE-U, including the members of the LTE-U Forum -- whose members also are members of the Wi-Fi Alliance -- are pleased to continue our ongoing collaboration with the industry through our work with the Wi-Fi Alliance initiative to develop an agreed-upon coexistence test regimen that will ensure that LTE-U and Wi-Fi successfully co-exist in the unlicensed spectrum, where the watchword is permission-less innovation, as Chairman Wheeler has correctly recognized.” The Wi-Fi Alliance ex parte recapped meetings between alliance CEO Edgar Figueroa and front-line staff of Wheeler and of Commissioners Mignon Clyburn, Ajit Pai and Jessica Rosenworcel, plus with Office of Engineering and Technology representatives. The Wi-Fi Alliance said it plans a Coexistence Test Workshop for the week of Feb. 8. The group's members include Apple, Broadcom, Cisco, Comcast, Intel, LG, Microsoft, Sony and T-Mobile, its website said.
