Results from a study by market research company GfK has found that Wi-Fi usage is on the rise, with home users forming the majority of customers. Apparently some 380,000 wireless routers were sold in the first quarter of this year alone and that figure is expected to rise steadily. Those airwaves might be getting pretty crowded soon.

Sales will probably be helped along by the arrival of draft-n standard wireless networking and the ever increasing number of VoIP handsets making better use of the hotspots. Yesterday we reported that Buffalo has joined the ranks of Draft-n supporters, alongside Netgear and D-Link (and probably others) but we haven't seen any many products that can take full advantage of the increased data transfer rates yet - more things like this would be good though.

Interestingly, business users heavily prefer mobile wireless technology such as 3G cards. I assume that's because they can happily pass on those monumental data charges to some faceless corporation.
