Berkeley Varitronics Systems, Inc. has updated its Yellowjacket b/a/n/g Tablet Analyzer for 802.11n Wi-Fi networks. 802.11n networks have increasingly become complex to deploy; therefore the wireless tools to measure and monitor RF performance have had to advance proportionally. IEEE 802.11n has distinct advantages over the previous 802.11b & 802.11g standards in that it has added (MIMO) Multiple-Input Multiple-Output and 40 MHz channels to the physical (PHY) layer. MIMO technology uses multiple antennas that provide more information over that of a single antenna. The use of antenna diversity and spatial multiplexing provide significant improvements in performance. The company added this capability to the Yellowjacket b/a/n/g Tablet Analyzer along with the Swarm mapping software in order to provide comprehensive Wi-Fi measurements in a single tool sought after by IT Managers and Security personnel.
