Download Datasheet (PDF)

The EMTS Telecom Services LTE Band Selective in Line Booster (ILB) is integral to the LTE network deployment. It extends the coverage by receiving processes and amplifying the RF signal. The single-band LTE-1800 MHz ILB s 30dBm booster provides an affordable solution to solve indoor signal coverage problems in LTE 1800MHz systems. Due to signal fading and attenuation caused by architecture obstacles, the signal strength is weak; our ILB, with its easy installation & maintenance, can help carriers get a faster return. The ILB works as a relay between the BTS or pickup repeater and mobiles. It picks up the signal from BTS or the repeater via coaxial connections, linearly amplifies the signal, and then retransmits it via the Indoor Signal Distribution System to the weak/blind coverage area. The mobile signal is amplified and retransmitted to the BTS in the opposite direction. It provides two versions of a full band or a band selective fix band (factory set) type.

Key Features
