Carlson Wireless Launches The Longhaul ST, The Next Generation Of Wireless Microwave Connectivity For Multiple Applications

Today’s traffic-monitoring project or public safety agency demands higher data throughput and lower latency—at an affordable price. The LongHaul ST seriesis Carlson Wireless’s answer to these requirements, with both an indoor rackmount version as well as an outdoor integrated antenna.

The third series in the LongHaul product family, the ST provides even higher data throughput and greater network capabilities than its predecessors.  This performance data has already been proven during a recent independent field test where it outperformed all competitors.

In a daisy-chain network test for urban traffic monitoring involving several microwave links, the ST lost zero throughput and delivered rates three times higher than other products. (see related story)

Several links are necessary in a traffic-monitoring network because of the many obstacles in an urban environment, from the tree-covered intersections where traffic cameras are located to the tall buildings where the signal must reach.  Each link has to be extremely fast and the delay extremely short.

The ST makes it possible to monitor clusters of intersections from a central point. And the channels may be narrowed from 20 to 10 to 5 MHz without channel overlap. The fact that it’s possible to realize upwards of five links in a row without decreasing bandwidth opens up a world of applications in many cities.

Outdoor antenna system for LongHaul ST

Carlson Wireless’s trademark low latency means that wireline-quality digital VoIP phone lines can be transmitted alongside lightning-fast Ethernet. With the optional 4-port IP-to-analog device, the ST can integrate traditional phone systems into a VoIP network.

The ST is also the first Carlson Wireless product to utilize Gig-E ports, allowing for unrestricted data output at the same speed it is transmitted over the air (up to 270 Mb/s).  These functions are among over 45 unique product features included with the new LongHaul ST.
