Channel-selective GSM/UMTS/LTE repeaters
Channel‐selective versions of SEE's 2G GSM / 3G UMTS / 4G LTE repeaters are also available.
A "selective filter" option may be added independently to the uplink and/or downlink.
This digital unit also allows:
o Selection of up to 4 frequency sub-bands to repeat (therefore eliminating other sub-bands)
o Independent programming of the following settings for each of these sub-bands:
§ Central frequency
§ Bandwidth (100kHz ‐ 5MHz)
This feature therefore allows for use of the repeater to eliminate unwanted carriers, and only repeat signals for the required operators.
