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. 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
