Networks on LTE bands 1, 3 (LTE-FDD) are suitable for roaming in ITU Regions 1, 3 and partially Region 2 (e.g. Costa Rica, Venezuela, Brazil and some Caribbean countries or territories. Networks on LTE band 20 (LTE-FDD) are suitable for roaming in ITU Region 1 only.

As of March 2013, 156 commercial 4G LTE networks existed, including 142 LTE-FDD networks and 14 LTE-TDD networks. [86] As of November 2013, the South Korean government planned to allow a fourth wireless carrier in 2014, which would provide LTE-TDD services, [ 77 ] and in December 2013, LTE-TDD licenses were granted to China's three mobile ...

Specific requirements of the IMT-Advanced report included: Based on an all-IP packet switched network. [4]Interoperability with existing wireless standards. [5]A nominal data rate of 100 Mbit/s while the client physically moves at high speeds relative to the station, and 1 Gbit/s while the client and station are in relatively fixed positions.
The Asia-Pacific Telecommunity (APT) band plan is a type of segmentation of the 612–806 MHz band (usually referred to as the 600 MHz & 700 MHz bands) formalized by the APT in 2022–2023 and 2008-2010 respectively [1] and specially configured for the deployment of mobile broadband technologies (e.g. most notably Long Term Evolution, LTE).
For example, a walkie-talkie or a DECT phone or so-called TDD 4G or 5G phones requires only a single frequency for bidirectional communication, while a cell phone in the so-called FDD mode is a full-duplex device, and generally requires two frequencies to carry the two simultaneous voice channels, one in each direction.
