Auxiliary Radio Communication System
- The wireless communication ancillary facility system is a facility necessary for fire fighting activities in buildings which enables seamless wireless communication between the fire brigades on site and on the ground which minimizes the damage by responding to threats of human lives caused by accidents such as fire.
System Outline
Functions and Features
- Transmits 450MHz band wireless signal to low band frequency to minimize transmission loss
- The transmitted low-band frequency wireless signal is re-converted to the 450MHz band, which is the wireless communication frequency band of the radio and transmitted through the antenna
- Application of DSP technology to avoid oscillation which occurs in two-way radio communication using one feeder cable
- Seamless two-way wireless communication without interference
- Prevent mutual interference when using both fire-fighting radios and management radios simultaneously
- Support up to 64 channels of management radio
- Support inter-floor mutual communication regardless of location
- Construction cost reduction and easy maintenance with high efficiency and low loss transmission technology reducing the number of transmission loss compensation amplifiers and various transmission line equipment
