Mike, I was just about to post the same quote, and I looked down and saw it in your post.
How viable is 5GHz in this situation? I mean, we've now rolled out two AC buildings. The signals go through 1 wall fine, but 2 walls or a single outside wall and the signal is non-existent. If they won't be allowed to crank it up to 11, is it useful? What am I missing? -Brian ' ________________________________ From: The EDUCAUSE Wireless Issues Constituent Group Listserv [[email protected]] on behalf of Mike King [[email protected]] Sent: Thursday, August 27, 2015 8:08 PM To: [email protected] Subject: Re: [WIRELESS-LAN] LTE over Wi-Fi spectrum sets up industry-wide fight over interference Quote from the article: T-Mobile wrote. Qualcomm said its testing<http://apps.fcc.gov/ecfs/document/view?id=60001104452> shows that Wi-Fi access points often have better throughput when sharing a channel with LTE-U than when sharing a channel with another Wi-Fi access point. Here's my comment: We'll duh. Two AP's on the same channel is something we try to avoid, because "It's Bad®". How about comparing throughput of an AP with no interference (Cause that's what we call two AP's on the same channel), and a AP with LTE-U on the same channel.

Telecom companies won't be able to easily provision an LTE-U "tower" every 30 meters within our campus, limiting their ability to cause interference. Instead, I see them mostly using this fill coverage gabs by selling wifi routers with an LTE-U service built-in for rural and other underserved areas. Additionally, I see them using this to try to push their backhaul costs onto other providers. A Verizon could get a Cox to help foot their transit bill by selling their special routers to customers at just below their cost. Consumers would buy these routers because they are cheaper, and suddenly Verizon gets some "free" spectrum in that area and can manage things so the call terminates at the Verizon location nearest the other end of the conversation. The biggest risk on our end is probably having students bringing routers with this ability into their residences, but we can deal with that the same way we've always done... well, almost, depending on how the whole Mariott thing turns out.
