Mobile network infrastructure isn't exactly an enthralling dinner-table topic, and yet somehow, O2's actually managed to make it sound interesting. The carrier's announced that it's switched on its new "self-optimising intelligent network," which responds to customers' needs in real-time. Apparently it's the first of its kind in the UK, but what makes it so smart exactly? Well, according to O2, the network constantly monitors mobile usage in any given area. When it notices demand catching up with supply, causing a decline in network quality, O2's mobile antennas are remotely repositioned to boost signal and bandwidth in response. Or, as the company puts it, the network "determines the best possible coverage and capacity parameters for all customers in a defined area."
