Partly prompted by getting a shiny new TomTom bluetooth GPS recently, I thought I’d fire up Wififofum on the way home to see what it found. It’s been about a year since I last did this and plotted the data and it was fairly interesting to see the difference. There are a *lot* more access points out there today, and more now have WEP turned on. Shipping them secure by default must be helping 
Of course the ones with WEP turned off may be using some other security, but if the SSID is default I’d guess not
Last time I did this I plotted the results using google maps. My code seemed to have broken over the last year so I decided to try the Microsoft Live mapping api. I was pleasently suprised to find it much easier to use than the Google one, and it seems to render the maps quicker as well I’ve also done things properly this time and uploaded the data into a database and made it easier to import data. The prod-development AP with no WEP outside of the Hornby factory might be interesting
The map is here for the interested.
