ANTENNA SYNC

ANT-SYNC is an active GPS/GLONASS antenna designed to filter and amplify RF signals received from global navigation satellite systems (GNSS) and feed them to a GNSS receiver at InfiLINK XG, InfiLINK XG 1000 families outdoor units. GNSS receiver recovers timing and positioning data which is used to provide timing reference for TDD synchronization as well as to make device location information available for EMS and NMS systems via SNMP protocol.

ANT-SYNC is a fully ruggedized weather-sealed outdoor unit compliant to IP66 and IP67 water and dust protection standards.

As an active antenna, it protects the receiver from interference coming from co-located 3G/LTE BTSs, which would make GNSS signals irrecoverable otherwise. It requires VDC power for normal operation, which is fed via the RF port, so it can only be used with compatible GNSS receivers such as those built into InfiLINK XG, InfiLINK XG 1000 families.

TDD synchronization allows multiple co-located InfiLINK XG/InfiLINK XG 1000 families units to operate co-channel or use adjacent channels thus achieving frequency re-use and eliminate self interference. Because of GNSS-based timing reference, both intra- and inter-site synchronization can be supported. Refer to InfiLINK XG/InfiLINK XG 1000 Technical User Manual for more details.
