Prior to the launch of Freeview, National Grid Wireless (formerly Crown Castle UK) the company responsible for providing transmission services for the Freeview service, made a number of improvements to the transmitter network, the end result being an improvement in the robustness of the signal and an increase in overall coverage. National Grid Wireless will continue to make improvements to the Freeview network to improve the quality of the signal and increase coverage but, regrettably, National Grid Wireless are unable to give a definitive timescale as to when Freeview will be available in areas that cannot currently receive it.
