One of our Customers faced the problem of increasing the real throughput in the communication in the Moscow subway. They needed connection between a moving train and stationary points in a tunnel, with NLOS conditions and roaming between APs in the tunnel. The system is based on the Cisco 5 GHz Access Points of Cisco Aironet 3600 Series AP units and WiBOX PA D4M5-20HVX MIMO 4x4 directional antennas. The installation has been done at the standard of 802.11n on MIMO 4x4 technology (exactly with 3SS + one stream for a beamforming).

The goal was to get the maximum throughput between a moving point in the train and stationary points in the metro. In the tunnel there was a necessity to use the most directional antennas as it’s possible.

One of our local customers was looking for an efficient radio link for a short distance of 520m. We offered him our new MIMO 2x2 antennas of WIBOX PA M5-20HV. The customer installed RouterBoards 800 with R52nM in the antenna boxes. Then sent the test results to us. It was hard to believe that transfer of over than 300Mbps is possible in 802.11n MIMO 2x2.

Currently we are going to launch new MIMO 2x2 5 GHz and 6 GHz client side antennas which will operate at the frequency from 5.15 up to 6.50 GHz, with constant parameters which is unattainable for standard products. The separation between polarizations of 40dB allows to use the full MIMO standard options.

The research department in Wireless Instruments company designs and manufacture custom antennas for the special orders (Wi-Fi, WiMAX, LTE, GSM, MIMO 3x3, MIMO 4x4 etc.) . We have the professional design software and the measurement system.

Wireless Instruments basing on strong experience on many installation sides, resolved to change the standard way (using by most of the manufacturers) of producing mounting systems from steel (an angle-iron). The company decided to design much more solid mounting system, which can ensure much stronger antenna stability during strong winds. That…

The main design point of  WiBOX series was the combination of an attractive design and ergonomics. Furthermore there was a market research, where the antenna fitters were asked for the best and unique features which they would like to see in new products and make them better then the competitor’s boxes with antennas. As the…
