Quite a few posters have problems with getting a decent Wi-fi signal in their houses, through walls. There is a possible solution on the horizon, white space technology. In consultation at the moment. "A white space device uses gaps in radio spectrum, called ‘white spaces’, which exist in between frequency bands that have been reserved for TV broadcasting. Use of these white spaces would allow devices to transmit and receive wireless signals for applications such as broadband access for rural communities or innovative ‘machine-to-machine’ networks. Compared with other forms of wireless technologies, such as regular Bluetooth and Wi-Fi, the radio waves used by white space devices will be able to travel larger distances and easily through walls. This is because they would use the lower frequencies that have traditionally been reserved for TV. Enhanced Wi-Fi: The majority of current Wi-Fi devices operate in spectrum at 2.4GHz.
White spaces could provide new capacity, while boosting the range of devices, potentially enabling Wi-Fi networks that stretch across towns and cities. This is due to the lower frequency of TV white spaces (typically between 470 MHz and 790 MHz)."
