Pico Digital Repeater

 

Digital tri band repeater is designed by adopting SDR (software Define Radio) technology based on FPGA (Field Programmable Gate array) & DSP (digital Signal Processing) platform.  FPGA & DSP platform enables the flexibility in frequency bands selection across the technologies (GSM900, GSM1800 & WCDMA2100) through software very easily at field without changing any hardware. Digital Tri-band repeater has designed with built in Modem to connect with a centralized Network Monitoring Software.  Network Monitoring Software can control and monitor the repeaters operational features like gain, output power, frequency band allocations and real time alarms from the field.

Significant Features

Ø Support Tri-band systems (GSM/DCS/UMTS/FD-LTE /TD-LTE) is available.

Ø Frequency bands allocations can be changed by software locally or remotely.

Ø Flexible Bandwidth, Tunable and Movable by Software, Customized Band

Ø Maximum 6 sub bands per technology

Ø Frequency bands can ON/OFF by soft switch

Ø Better out of band rejection compared to Analog SAW technology

Ø Built in Modem for remote control

Ø Complies the ETSI & 3GPP2 Standards

Ø High Working gain

Ø Auto shut down and AGC based on threshold settings

Ø automatic detection of isolation, and can automatically eliminate

self – excitation, The elimination scope is greater than 30dB.

Ø Coverage of A 600m2 Apartment or A 1500m2 Basement
