20dBm 1800/3800MHz Wide Band Repeater with Adjustable Bandwidth
Dual band 1800/3800MHz digital band selective repeater designed for public and private network applications.
Product Overview
The Public/Private Network Repeater acts as a relay between the BTS (Public/Private Network) and mobile phones. It receives the strongest signal from the BTS via the donor antenna, amplifies the signal linearly, and retransmits it to weak/dead zone coverage areas via the transmitting antenna distribution system. The mobile signal is also amplified and retransmitted to the BTS in the opposite direction.
According to different working principles, repeaters are divided into two types:
Analog - Enhances signal strength by amplifying analog signals
Digital - Amplifies digital signals by converting to analog and then back to digital
