Bahrain’s Telecommunications Regulatory Authority (TRA) has released an invitation for expressions of interest in 30MHz of mobile spectrum in the 1800MHz band to be available for temporary release for a period of six months, extendable for further periods of two months duration. The available spectrum includes the following band segments, which have been packaged into three 2×5MHz paired sub-bands (uplink, downlink): 1750MHz-1755MHz, 1845MHz-1850MHz; 1755MHz-1760MHz, 1850MHz-1855MHz; and 1780MHz-1785MHz, 1875MHz-1880MHz. It is intended that this spectrum will be included in a future tender for full mobile licences, which together with additional spectrum (yet to be decided) should be capable of facilitating advanced, fourth-generation mobile systems such as Long Term Evolution (LTE). Therefore the current planned release of unallocated spectrum will be on a temporary basis only. The deadline for responses is 21 April 2011.
