Can network sharing propel LTE?

The recent announcement by Tele2 and Telenor to jointly build and own a 4G network in Sweden highlights what might become a trend for future 4G networks. In their announcement, both companies said they will form a 50:50-owned joint venture to roll out a nationwide 4G LTE network in Sweden. Not only will they share their active network components - essentially the RAN - but they are sharing the spectrum too. The deal includes both the 2100MHz and the 900MHz spectrum bands, ensuring that the network will have nationwide coverage. By sharing their RAN and spectrum, Tele2 and Telenor will effectively operate as mobile virtual network operators on their jointly owned network. Article
