This article reports on the new management products that give network executives tools to control radio waves, the most elusive element of wireless local area networks (WLAN). The RF tools, so-called for their ability to read radio frequency waves, lets administrators see details such as Internet protocol headers, identify new devices that start transmitting, and identify electro-magnetic interference, among others. The new products use radios that scan the air, pull data from the radio chipsets in WLAN devices, and expose via graphical user interface displays and alarms what is happening on the Layer 1 wireless connection. Some of the products are presented which range from full-blown RF management systems to offerings sized for either small or large WLANs, to incremental improvements in existing products.
