Sensortec ST-GB series millimeter-wave radio links represent a new class of feature-rich backbone links for the carrier, government, and enterprise users. The ST-GB Series features a full-gigabit, full-duplex throughput with fiber interface using robust BPSK modulation for preserving the maximum link budget.
ST-GB Series offers two additional features -(1) adaptive rate adjustment allows rate fallback to 100mbps in cases of adverse RF conditions, using a much smaller channel size and improved Rx sensitivity, and (2) AES Encryption for the secure transmission of data at line speed and with little latency.ST-GB series systems are available with either 1FT low profile antennas or 2FT antennas for extended distance coverage.
