November 2017 Discussion Points IEEE 802.11 has a record of successful spectrum sharing between licensed and unlicensed use Part 15 REQUIRES licensed services to be protected Protection of radars in the 5 GHz band has been a major success Even the weather radar industry, the most vocal critic of DFS, now publicly states that DFS works to protect their radars The FCC three years ago re-opened the 5600-5650 MHz band, as they were convinced that DFS does protect the incumbents All interference received was from devices with non functioning DFS Older systems, before DFS was required Rogues that turn off DFS or move non-DFS channel devices into the band; all enforcement issues TVWS has not had sufficient deployments to judge efficacy Agenda Rich Kennedy, HP Enterprise

November 2017 Discussion Points [2] The Wi-Fi industry has engaged a major engineering firm to study all of the issues in the four discrete segments of these bands Interference mitigation studies will show that all incumbents will be protected…or the FCC will not allow Wi-Fi in these bands Ruling that unlicensed cannot share in these bands would be a major blow to the growth of the primary wireless onramp to the Internet, to the detriment of American people, business and services that rely heavily on Wi-Fi Rich Kennedy, HP Enterprise
