The UK telecoms regulator, Oftel, has just (1st May) produced a briefing note that seems to encourage the idea of infrastructure sharing of third generation mobile networks. It defines 'infrastructure sharing' as including both physical sharing of sites, and also the sharing of capacity. The example Oftel gives is interesting. It says that two operators could divide up the country, one, say, building a network in Manchester, the other in Leeds. They could then allow free 'roaming' between the cities.
Our primary purpose is to provide revenue forecasts for the next three years. Our central forecast sees Retail revenues falling at percentage rates in the low single digits. Wholesale revenues are driven by different forces and will rise rapidly next year, and at a slower rate thereafter. The rise in Wholesale revenues will not be enough to stop a fall in overall income.
