Detailed Product Description

Main Features

Monitoring software can be upgraded locally or remotely;

Avoid interfererence from co-frequency;

Enlarge the coverage area with omnidirectional antenna;

Extend the signal distance of base station;

Wide dynamic range,low power consumption and low noise figure.

main functions

Auto Shut-Down

Protect from over output power

High isolation from uplink to downlink,high stability and reliability.

ALC (auto level control)

Software set up the gain, power and channel etc.

Display output figure

Application Range

Enlarge the service area, eliminate blind area obstruct from edelweiss, building and hurst etc.

Enhance the electromagnetic field, and enlarge the cover area.

Located along the freeway, enhance the cover efficient

Resolve the coverage of the large building, marketplaces and underground where signal blind area

Idle signal in Base station induced to high traffic area so as to optimize signal coverage
