Thailand’s auction of fourth generation spectrum has gotten more complicated. The National Broadcasting and Telecommunications Commission (NBTC) had hoped to auction 30 MHz of spectrum in the 1.8-GHz band, but now will allocate only 25 MHz.
As a result, two licenses, each of 12.5-MHz bandwidth, will be made available, instead of two allocations of 15 MHz each.
CAT Telecom also has withdrawn from the auction, a move required because it could not secure a required foreign partner
The problem is that the remnant 2.5 MHz of spectrum might be difficult to wring value from, as Long Term Evolution networks are channelized in 5 MHz increments. In the intended former plan, a carrier might have allocated 10 MHz in one direction, 5 MHz in the other direction.
If I understand the channelization plan, 5 MHz channelization will be the norm, with a remnant 2.5-MHz available in one direction, with a separate carrier. How efficient that might be is a question many would have. Large contiguous blocks of spectrum are most efficient. Small non-contiguous blocks of spectrum tend to be the least efficient.
