Maya WileyMaya Wiley could torpedo LAA"Coverage is at signal strengths below -72 dBm and down to signals as low as -90 dBm," New York City Counsel Maya Wiley tells the FCC and standards groups. We (I'm a New Yorker) are demanding that Verizon's LTE in WiFi spectrum not interfere with New York's plan to connect everyone, starting with 7,500 free gigabit Kiosks. Verizon's LTE proposal - now a subject of controversy in 3GPP - specifies that LTE-U will choose an unused channel if available. This data raises the question of "What is an unused channel?" I infer that lowering the detection threshold will probably be necessary.

Technology is moving fast; rules are changing slowly unless the change has a powerful patron. New York's petition has implications worth exploring.Harold Feld has pointed to changes in wireless rules that improve performance without undue interference. His ideas seem sensible to me. I'm presenting here the NYC claims and will be asking experts for opinions in a follow-up article.

"LinkNYC will provide strong coverage at a minimum of 150 feet from a kiosk. The initial links are providing coverage up to 400 feet in some cases, including down side streets, which means many more people in many more parts of the city will be able to take advantage of the system's seamless handoff facility. That scale of consistent and abundant connectivity has the potential to drive enormous innovation for the city. Based on initial analysis, that additional coverage is at signal strengths below -72 dBm and as low as -90 dBm."  

LinkNYC articles

Any wireless technology deployed in a band that provides broadband access o millions must incorporate the basic protocols for fair sharing … We remain concerned about the lack of coexistence mechanisms for lower level Wi-Fi signals. …

Ensure that the specification fully protects such signals.  Such Wi-Fi signals are necessary to deliver solid broadband access to millions of the city's residents and visitors. …                                                                                                   

Sincerely, Maya Wiley, Counsel to the Mayor

New York City is credible enough I'm comfortable reporting their point of view, especially as I found numerous examples of successful connections at low ratios. I don't know enough to evaluate how low the level should go. I'm reaching out to all the parties for more technical details, as well as some senior experts. Better information needed  I went ahead with this article because the issue is pressing at the FCC and 3GPP.
