Dual band 1800/3500MHz digital band selective repeater designed for comprehensive signal coverage solutions.
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 then retransmits it to weak/dead zone coverage areas via the transmitting antenna distribution system. Mobile signals are also amplified and retransmitted to the BTS in the opposite direction.
According to different working principles, repeaters are divided into two types:
