From Tables 5.5-1 "E-UTRA Operating Bands" and 5.6.1-1 "E-UTRA Channel Bandwidth" of the latest published version of the 3GPP TS 36.101, [1] the following table lists the specified frequency bands of LTE and the channel bandwidths each band supports.
The 3GPP specification work is done in Technical Specification Groups (TSGs) and Working Groups (WGs). [23] There are three Technical Specifications Groups, each of which consists of multiple WGs: RAN (Radio Access Network): RAN specifies the UTRAN and the E-UTRAN. It is composed of six working groups.
The first version of LTE-Unlicensed is called LTE-U and is developed by the LTE-U Forum to work with the existing 3GPP Releases 10/11/12. LTE-U was designed for quick launch in countries, such as the United States and China, that do not mandate implementing the listen-before-talk (LBT) technique.

In the lower frequency bands to be used in rural areas, 5 km (3.1 miles) is the optimal cell size, 30 km (19 miles) having reasonable performance, and up to 100 km cell sizes supported with acceptable performance. In the city and urban areas, higher frequency bands (such as 2.6 GHz in EU) are used to support high-speed mobile broadband.
Further GSM-850 is also sometimes called GSM-800 because this frequency range was known as the "800 MHz band" (for simplification) when it was first allocated for AMPS in the United States in 1983. In North America GSM-1900 is also referred to as Personal Communications Service (PCS) like any other cellular system operating on the "1900 MHz band".
LTE-M or LTE-MTC ("Long-Term Evolution Machine Type Communication") is a type of low-power wide-area network radio communication technology standard developed by 3GPP for machine-to-machine and Internet of Things (IoT) applications.
(Generally speaking, lower frequencies allow carriers to provide coverage over a larger area, while higher frequencies allow carriers to provide service to more customers in a smaller area.) In the U.S., the analog AMPS standard that used the cellular band (800 MHz) was replaced by a number of digital systems.
