42% of Worldwide Households Expected To Have Wi-Fi By 2016 91
retroworks writes "'Wi-Fi network use will nearly double in homes around the world come 2016, according to new Strategy Analytics research. Already used in some 439 million households worldwide, equivalent to 25% of all households, Wi-Fi home network penetration will expand to 42%.' The report says China already has the highest home Wi-Fi use."
Channel Crowding (Score:5, Interesting)
I hope there appears some solution to the channel crowding already extant with so many home wireless networks. With only channels 1-11 available, and those overlapping with each other, it's already difficult to try to find a clear niche of spectrum. I live in a rural town about 30 miles from the nearest major metropolitan area, and still I count around 15 wireless networks within detectable range.
Basically, it's all just too crowded.
Either the FCC needs to open up some more surrounding spectrum to use, 5ghz networks need to pick up in popularity, or some other technology needs to become available.

In the meantime(and/or forever, since it seems to be an accepted truth that any available spectrum is either the god-given right of legacy broadcasters or must be sweethearted to a cellular Telco as quickly as possible lest the terrorists win) it would be nice for access points to 'back off' more intelligently.
A limited number of AP deployments are actually looking for maximum range. The rest only actually want enough range to handle the X devices in the household; and any spillover is useless or worse. It would be useful for the client and the access point to be able to exchange information with each other on signal quality, and settle on minimum levels needed for the distance and speed required.

Wifi improvements are achieved because of the limited spectrum. The problem with the "more power" approach is obvious. The virtually same problem exists with "more bandwidth". More bandwidth will not lessen the congestion, because access points will use wider bands instead of allowing more access points to use non-overlapping bands.

I wish I had mod points for you, I really do...
In my apartment, there are literally 30+ networks within range at all times, and to make matter worse, they channel surf up and down the band constantly. It didn't matter what channel you picked, if it was clear enough to be attractive, within a few minutes there would be a handful of other networks camped on top of yours as they constantly searched for clean channels.
I ended up having to go completely hard-lined because I couldn't even pull down 5 meg on a wireless-N connection 15 feet from the router, so now I've got wires across my ceilings and around doorways and shit all over my apartment, but at least I can pull down the 30 meg service I'm paying for. I just did a quick search with the Wifi scanner app on my phone just now and there are 12 networks parked on channel 5, 7 on channel 7, and the rest are just sitting here chasing each other up the band as I watch in real-time.
There needs to be a better way for routers to communicate with each other when they are within interference range and negotiate channel assignments because it's only going to get worse as more phones and shit come out with built in hotspots of their own, not to mention automobiles out in front of the damn building as well competing for spectrum.
