Spectrum sharing with LTE is conceivable but not trivial

LTE has been designed to operate in high-interference environments. The technology divides wide radio channels of 5 MHz or 10 MHz into tiny subcarriers of 15 kHz for actual transmission with the ability to selectively use just a subset of subcarriers at particular times. This makes it fundamentally different from previous CDMA technologies such as CDMA2000 and HSPA that employ wide radio channels of 1.25 MHz in the case of CDMA2000 and 5 MHz in HSPA. This use of subcarriers enables LTE to avoid frequencies on which there may be excessive interference. This core feature of LTE may enable the technology to support spectrum sharing, but don't get too excited that we have identified the silver bullet to the looming spectrum shortage. There are many caveats.

UK's operators have banded to speed up 4G LTE 800 roll-out

O2, Vodafone, Everything Everywhere and Three have banded together to speed up the deployment of 4G services. Ofcom writes that the four have come together to form Digital Mobile Spectrum Limited (originally called MitCo), a company that will be funded by the successful bidders for 800MHz spectrum in the forthcoming auction. If any other party acquires spectrum in the auction, they can immediately become a shareholder in DMS Ltd.

The company will be responsible for ensuring consumers continue to receive clear Freeview TV signals following the roll out of 4G mobile services in the 800 MHz spectrum band. The early creation of such a company was one of the solutions highlighted by Ofcom and the government during conversations with mobile operators about speeding up the roll-out of 4G.
