    The State of Wireless London

    INFO VISUALIZATION:Julian Priest has an interesting piece up about, well, "The State of Wireless London."







    Shown here is a visualization of shown nodes for commercial wifi services in Greater London, however the piece talks about home and office wireless access points also. In a fairly crude manner, he estimates the total number of WAPs inside the M25 highway circling London to be about 20,000:





    Total Distance flown 348.4 km

    Total nodes seen 1525

    Radius of view ~0.5 km

    Flight height ~0.4 km

    Ground area covered ~0.3 km -2

    Total area covered ~98 km -2

    Node density ~15.5 nkm -2

    Estimate of nodes within the M25 ~19451
