LTE WiMax re-allocation

The Singapore Infocomm Development Authority (IDA) is working on the re-allocation of spectrum bands available for 4G services:

2.3 GHz and 2.5/2.6 GHz bands will expire in 2015.
900 MHz and 1800 MHz band assignments will expire in 2017.
Despite the fact that 4G services are currently running in the existing bands and therefore a conflict is arising at the development stage, IDA decided not to re-allocate 900 MHz bands for the time being.

For the use of LTE or WiMax the below bands are under discussion:

• 14 lots of paired spectrum (2x5 MHz per lot) in the 1800 MHz band;
• 8 lots of paired spectrum (2x5 MHz per lot) in the 2.5 GHz band;
• 6 lots of spectrum (10MHz per lot) in the 2.3 GHz and 2.5 GHz.

Spectrum caps are suggested, of up to 2x45 MHz of spectrum in full for 1800 MHz and 2.5 GHz band paired categories. The consultation also suggest 2x20 MHz in the 2.5 GHz band, for which only new candidates may place a bid.

In 2021, the 2.1 GHz spectrum for 3G mobile will expire.
700/800 MHz spectrum is not expected to be longer available.
