Wireless Developer Network
The WirelessDevNet is a pretty cool website, and has channels on a bunch of interesting topics, in particular Bluetooth and Location Based Services.
They offer an RSS Feed, but it appears to be for the entire site, and isn't available per channel. Pity, but still good.
Obviously, it is targetted more towards developers, so if you're into that sort of thing, then this site might be for you. It contains a lot of articles written locally, as well as pulling in and referencing articles and tutorials from other locations, so it's a decent 'landing pad' for wireless development.
Wireless News @ Wired (Funnily enough!)
Wired News offers a feed all wireless-related news stories that they are covering, conveniently located on their /news/wireless page.
Wi-Fi Networking News
Wi-Fi Networking News looks like it has a pretty good finger on the pulse of what's going on in the wireless world, with very regular updates and a good coverage of industry info.
Note to self: keep an eye on these guys.
A Few Good Links
I was having a look on TechRepublic and found some good articles about wireless technology (just search for 'wireless' on their site);
Wirelessweek.com - Pretty good info site
Wirelessweek.com is a pretty good site for information about all sorts of things in the wireless industry. It doens't appear to have an RSS feed unfortunately, but is a good place to catch up on what's going on.
