Arrista’s CR-100 in-building repeater is a Class B Broadband device, it will
process the entire cellular 800MHz spectrum. Input and output duplexers and
band pass filters in the downlink and uplink path provide the repeater’s
filtering and isolation. The maximum gain in each of the downlink and uplink
path is 60dB. Both the downlink and uplink paths incorporate automatic
gain/level control, to ensure that downlink and uplink power amplifiers are not
overdriven and operate free of distortion. As well, the automatic gain/level
control ensures that in normal operation the downlink and uplink gain mirror
each other. The CR100 also has primary and secondary subscriber ports,
allowing the repeater to double the in-building coverage area.
