4G LTE B43 (TD 3700)
Band 43 is an LTE operating frequency Band. LTE is designed to work across a number of frequency bands – E-UTRA operating bands- currently ranging from 450 MHz up to 3.8GHz. The available bandwidths are also flexible starting with 1.4 MHz up to 20 MHz with Carrier Aggregation allowing use of wider multiples. LTE is developed to support both the time division duplex technology (TDD) as well as frequency division duplex (FDD). Availability of specific bands varies per country and operator.
4G LTE Band 43 is defined as for use as follows:
|Frequency Range:||3600 – 3800MHz|
|Width of Band:||200MHz|
|Channel Plan||TDD (Time Division Duplex)|

Available 4G LTE Hardware for Band 43:
4G LTE Base Station hardware
4G UE (User equipment) Terminals
(Please enquire for availability of specific devices supported for this band)
LTE is a standard defined by the 3GPP as technology for 4th generation (4G) mobile wireless networking technology.

FDD and TDD LTE frequency bands
FDD spectrum requires 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.
The greater likelihood is that a single UE or mobile will need to detect whether a TDD or FDD transmission should be made on a given band. UEs that roam may encounter both types on the same band. They will therefore need to detect what type of transmission is being made on that particular LTE band in its current location.
The different LTE frequency allocations or LTE frequency bands are allocated numbers. Currently the LTE bands between 1 & 22 are for paired spectrum, i.e. FDD, and LTE bands between 33 & 41 are for unpaired spectrum, i.e. TDD.
TDD LTE frequency band allocations
With the interest in TDD LTE, there are several unpaired frequency allocations that are being prepared for LTE TDD use. The TDD LTE bands are unpaired because the uplink and downlink share the same frequency, being time multiplexed. TDD LTE is popular in ISP and closed networks where there is either predominantly Data-centric use (rather than voice), no legacy of 2G/3G, or pressure on limited spectrum available.
