The Wi-Fi Alliance’s long-awaited – and controversial – LTE-U Coexistence Test plan has landed.
The reg-walled test plan is supposed to help work out if LTE-U – the mobile carriers’ plan to use unlicensed spectrum if nobody else is talking – can coexist with Wi-Fi.
Carriers, already under a spectrum squeeze, are hoping they can pitch their tents on Wi-Fi’s campground, promising that LTE-U won’t disrupt Wi-Fi. will play nice if there are Wi-Fi users around.
Negotiations between the groups and America’s Federal Communications Commission have been tense, and at one point, Qualcomm complained its input to the test plan had been ignored.
In particular, Qualcomm had complained that the proposal to use -82 dBm as the threshold LTE-U would treat as “vacant” was too loose, and would leave a lot of Wi-Fi users out in the cold. That, however, is the lowest test threshold in the test plan.
Qualcomm is already conducting LTE-U field trials with T-Mobile, and early this week it asked the FCC for a 12-month extension to the authorisation it first received in May of this year
The aether is already soo much crowded by Wi-Fi connections in the range of the 2.4GHz that any new type of connection that want's to rely on that band will surely make a mess. Also such thing, in my opinion, is so prone to abuse by companies and hacking that I shudder.
You do realize that WiFi single channel n is like 130 mbps for like 150 ft in any given direction before the speed deteriorates.. Given that most isp only provide 50 to 70 theoretically that's the maximum one would need in a router... However what actually slows these little success down is actually buffer space and total bandwidth.. Mos to these don't have gigabit ethernet lol and only have 10/100 so not only is the buffer small but so is the pipe it's suppose to squeeze into
But yeah I agree with Qual com.. - 82 is far too loose.. Like that would be pretty bad for WiFi but honestly.. We should just move cell into the 3.6 ghz spectrum
