Why LTE should wait for 2.3GHz

In the UK the regulator OFCOM is considering auctioning the 2.4GHz spectrum to mobile phone operators for LTE. The problem is that this could compromise the performance of devices using Bluetooth, Wi-Fi and ZigBee in the adjacent 2.4GHz band. This article argues that the value of protecting the 2.4GHz spectrum may be orders of magnitude greater than the licence value of the 2.3GHz band, and that any proposal to allocate it to mobile operators should be delayed.
