Seeing that I live in a small part (Rhoose Point) of a small village (Rhoose) on the edge of Cardiff (Rhoose) Wales Airport I thought I’d try to find out how many wireless networks there are in a this small rural area.
To start with I have a wireless network on NETGEAR shared between 2 laptops, which is open and free to use for anyone who wants to try.
Looking from home I found closed networks on BTVOYAGER a network called HORACE and one called SABAD. I then drove round the village with my laptop and found several networks - cxl-wifi, another BTVOYAGER, belkin54g, SABSW, NETGEAR, HILLNET, Livebox-2FAD, WANADOO-550D, linksy_nth, and at Cardiff Wales Airport BT Openzone.
Out of the above only 3 are open wireless networks free to use by anyone who finds them and the others are all secure. The exception to this is the network at the airport which uses BT Openzone. To use this you have to buy access time, walk into a hotspot, which could be a train station, café, shopping centre, restaurant/bar or airport open your wireless laptop or PDA, and connect to the internet using wireless broadband. Although not free to use it does give you access to thousands of public hotspots in the UK and tens of thousands global hotspots worldwide.
A completely free wireless network would allow people greater access to the internet no matter what their income and would create greater mobility of use for laptops and PDA’s.
