(Telecompaper) A group of UK MPs has published a report calling on the government to do more to end mobile 'not spots' in the country. Their report calls for measures such as fines for operators not meeting coverage targets and national roaming to improve coverage for end-users. The report by the 'British Infrastructure Group' of MPs found that a third of mobile users, or 17 million people, across the UK report poor or no reception at home, while as many as 28 percent of rural spots in the country also lack coverage. The MPs want the government to request information from mobile operators by December on what they are doing to ensure a promise that the UK has at least 90 percent geographic voice coverage by 2017.
