LTE Frequency Bands

LTE support two duplexing modes:

  1. TD-LTE : Time Divison Duplexing LTE.
    • Both downlink and uplink transmission takes place at the same carrier frequency, unpaired spectrum, at different time slots.
    • The UL and DL slots are isolated through gaurd period. One merit TD-LTE is UL and DL capacity can be changed dynamicallcay.
    • No diplexer is required for TD-LTE, so cheaper UEs.
  2. FDD-LTE : Frequency Divisin Duplexing.
    • In FDD operation two carrier frequencies are required, paired spectrum. One for uplink transmission(f_{ul}) and other for downlink transmission (f_{dl}).
    • UL and DL isolation through gaurd bands.

The following LTE frequency band table is based on ETSI TS 136 101 V12.5.0(2014-11). The LTE/E-UTRA bands 1-32 are allocated to FDD-LTE and bands 33-44 are for TD-LTE bands. The initial choice TD-LTE is driven purely by spectrum availability.
