Product Description
20dBm Digital 700/800MHz RF Repeater - Band Adjustable Cellular Network Repeater
Product Overview
Dual band 700/800MHz digital band selective repeater designed for cellular network enhancement.
How It Works
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.
- Analog Type: Enhances signal strength by amplifying analog signals
- Digital Type: Amplifies digital signals by converting to analog and back to digital
