RE: [WIRELESS-LAN] LTE can mooch off of Wi-Fi spectrum with new Qualcomm chipset | PCWorld
Without a doubt, but I assumed it's unavoidable. Such is the nature of unlicensed spectrum. More wireless devices means more congestion, which means anybody for whom it's important that their systems work well will put them in the best available band until eventually it is saturated too. The only solution I can conceive of is to make enough unlicensed spectrum available that everything can coexist in an mutually acceptable manner. We don't have that with 5GHz. Add 60 GHz to the mix, with lots of high-capacity channels and poor propagation, and we probably get some breathing room, but even then I don't know how long it will last. -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Hector J Rios Sent: Friday, February 27, 2015 8:45 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] LTE can mooch off of Wi-Fi spectrum with new Qualcomm chipset | PCWorld All I can say is that if we continue down this path, the 5GHz band will eventually turn into the mess that the 2.4GHz band is today.

android 5 lollipop PMF
Anyone having issues with random android 5 devices connecting to PEAP/MASCHAPV2 wlan with Cisco gear? I have lots of working android devices on campus with 5, but I have had 4 that all can't connect to since update. All have the same issue can't get dhcp address. They will show that they passed auth in radius but the wlc shows them in DHCP_REQ state. It seems in reading things online that there are some issues with possibly android 5 having pmf turned on in the wpa_supplicant file. It seems you can copy the file off and change the setting but I'm just confused why other android 5 are working fine on the same wlan.

Re: [WIRELESS-LAN] LTE can mooch off of Wi-Fi spectrum with new Qualcomm chipset | PCWorld
It's gonna be a long time coming, but I think the eventual end-game here is we stop providing residential service at all. As the unlicensed spectrum deteriorates and the licensed providers (Verizon, ATT, et al) improve service and rates, eventually we'll hit a tipping point where it no longer makes sense. Students will just use their cell service. But again... that's a very long ways off yet. In the meantime, we have to do the best we can with the spectrum available to us.

They need the financial backing to stay in second and maybe close the gap on Cisco.
