Trango's new Atlas Series of Tri-Band Wireless Ethernet Bridges is the first radio of its kind capable of operation covering the license-exempt 5.8 GHz ISM band, the lower 5.3 GHz U-NII band, and the proposed upper 5.47 GHz U-NII band. The Atlas Series utilizes a high-performance OFDM architecture with dynamic adaptive modulation and a contention free, point-to-point protocol. With user selectable data rates from 6 through 54 Mbps and employing Dynamic Frequency Selection and Transmit Power Control as required by the new U-NII band regulations, the Atlas delivers 45 Mbps actual user throughput at the Ethernet port over a range from 6 miles with the integral antenna to 20 miles with the connectorized model and external high gain antennas.With the addition of the Atlas Series, our customers now have a robust, OFDM Ethernet Bridge solution with 45 Mbps throughput performance and total flexibility that covers the 5250 to 5875 MHz operating bands," said Zdravko Divjak of Trango Broadband. "The Tri-Band Atlas Series raises the bar in performance and value for high-capacity backhaul systems and is the first of many innovative broadband wireless connectivity products planned for introduction over the coming year."Posted by Rasel Sajal at 2:15 AM 0 comments
