9. Future of Wi-Fi

In the future many major cities intend to provide blanket coverage for anyone in the city, even in underground trains.

This is also happening in the private sector. For example, providers such a BT are forming a huge free Wi-Fi network in the UK for their existing customers by encouraging many of their customesr to allow their BT-home hub routers to be used as a Wi-Fi hotspot.

At the last count there were over 4 million hotspots in the network and it is the largest wi-fi network in the world.
