Cellular blockers interaction term - cellular blockers and heart

The ICS Repeater is working as a relay between the BTS and mobiles. It receives the low-power signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction. The Repeater is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve signal coverage and communication quality. Its easy installation and maintenance can help carrier get fast return. FeaturesAluminum-alloy casing with IP65 protection has high resistance to dust, water and corrodingReal Time interference signal cancellation (Multi-path Fading, Feed-Back signal) greatly reduces system isolation requirementNo interference to BTS by adopting linear amplifier with high gain and low noiseAdopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlinkRS-232 port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise repeater's working status and download operational parameters to the repeater Applications To expand signal coverage or fill signal blind area where mobile signal is weak or unavailable.
