Many operators are deploying LTE in low frequency bands (700 and 800MHz) to improve coverage in rural and in-building penetrations. Others are looking at LTE relays as an alternative approach. We examine the differences between a repeater, a relay and an LTE small cell and look at two specific operator use cases.
Technology recap – repeaters, small cells and relays
Cellular repeaters have been use for decades to boost weak signals, particularly indoors. They amplify the signal and rebroadcast it at the same frequency for both downlink and uplink frequencies.
