What is the maximum bandwidth of 1 LTE channel?

LTE RF Conformance Page 12 2. LTE Physical Layer • LTE physical layer (FDD/TDD) supports bandwidth from 1.4 to 20 MHz . Current LTE supports a subset of 6 different system bandwidths.

LTE carriers are narrower in bandwidth, up to 20 MHz maximum that can be aggregated together to create a channel bandwidth up to 100 MHz in LTE-Advance, or up to 640 MHz in LTE-Advanced Pro.

The channel bandwidth is defined as the effective bandwidth multiplied by the frequency reuse factor , where the effective bandwidth is the operating bandwidth that is appropriately scaled by the uplink/downlink ratio.

What is a Channel in LTE? The information flows between the different protocols layers are known as channels. These are used to segregate the different types of data and allow them to be transported across different layers.
