Usually when companies offer free stuff, they tie it up to something you pay for, but Nokia's decided to just install and activate a set of 26 Wi-Fi hotspots in and around central London and let everyone access them for absolutely nothing. 20Mbps wireless links are being installed into phone boxes as part of a trial, though there is a 1Mbps limit per user so as to prevent power users from hogging up all the bandwidth. Done in partnership with Spectrum Interactive, Nokia's test run is aimed at finding out how people use Wi-Fi on the move and to understand how to better serve their needs. It'll last until the end of the year, you don't need to have a Nokia phone or even like the company to make use of it, and if it proves a success, the free wireless connectivity will be made permanent early in 2012.
