20dBm Triple Band Digital Repeater

Support multiple sub-bands of 900MHz/1800MHz/2100MHz


Users can set the number of sub-bands and sub-band bandwidth


Real-time Isolation Detection: The device would automatically detect and alarm when insufficient isolation happens


Self-excitation Elimination: It will automatically decrease gains when self-excitation occurs because of insufficient isolation


Uplink Hibernation Mode: The device will enter hibernation when no cellphone user is in the coverage area, to save power consumption


Manual Gain Attenuation, with 1dB step to attenuate the gain among 1-31dB range umption


ALC could limit the output power to ensure stable signal


With built-in WEB page monitoring software, the device could be locally managed by a PC through LAN port connection. What’s more, it supports remote control and management through wireless connection with 3G Modem.

Digital wireless signal repeaters adopt signal processing technology such as self-adaptive and recognition technology. With digital filter and echo cancellation technologies, digital repeaters could detect and eliminate interference in the received signal. These technologies can make the isolation of the received and transmitted signal meet the expected standard and availably improve signal quality. With the development of software radio technology, digital wireless repeaters have gradually replaced analog wireless signal repeaters. As one of the maturest and most representative digital wireless repeaters, S20T-EDW applies the latest digital technology scheme, featuring low consumption, excellent RF indicators and more stable performance.
