4G/LTE Band chart

Ever wonder the meaning of the B (band) number shown on your device from B1 to 31 in the FDD and 33-44 in the TDD band frequencies

There is a growing number of LTE frequency bands that are being Assigned as possibilities for use with LTE. Many of the LTE frequency bands are already in use for other cellular systems, whereas other LTE bands are new and being introduced as other users are re-allocated spectrum elsewhere.

FDD and TDD LTE frequency bands

Usually FDD spectrum comes in pair bands, one of the uplink and one for the downlink, and TDD requires a single band as uplink and downlink are on the same frequency but time separated. As a result, there are different LTE band allocations for TDD and FDD. In some cases these bands may overlap, and it is therefore feasible, although unlikely that both TDD and FDD transmissions could be present on a particular LTE frequency band.
