<i>How can I find out if wireless ADSL is available in my are - Edgware / London?
And are there any other advantages to it over normal ADSL?
Would it be more convenient for people with laptops so that they can use it anywhere in the vicinity of wireless ADSL availablity?
Where can I find out more about it?</i>
Not sure if you actually know what you are talking about, so apologies if this is stuff you already know. "wireless ADSL" could be one of two things:
1) wi-fi hotspots - these are being rolled out in starbucks, coffe republic some hotels etc. It is pretty short range so you have to be pretty much in the buildings. It isn't a substitute for having a connection at home.
2) wi-fi at home - for this you just have an ordinary ADSL connection (wired) and then hook up a wireless access point of some description to it. Gives the benefit of wi-fi around your own home but beyond that is effectively the same as if you had the ADSL wired into your computer.
If you want to go the whole wireless way and use it outside your home you also need to sign up with an ISP who runs the hotspots you want to use. This means that at the moment you wouldn't have access to all hotspots unless you signed up with several, and it is pretty pricey.
