B45 (1500 MHz)

Band 45 is situated within the uncommon 1400 MHz spectrum and utilises a Time Division Duplexing (TDDTDD: A wireless communication technique that uses a single frequency band for both transmitting and receiving operations but separates these operations in time. In a TDD system, upstream (transmission from user equipment to base station) and downstream (transmission from base station to user equipment)…) configuration. This mid-band frequency is suitable for a range of environments from urban centres to suburban areas.

3GPP's ratification of Band 45 in September 2012, under Release 13, was strategically aligned with China's band plan, reinforcing the global harmonisation efforts in LTE spectrum allocations. The band however failed to gain traction and is widely considered obsolete.
