Copyright(C) 1994 - 2009 Network World, Inc. http://www.networkworld.com/newsletters/wireless/2009/070609wireless1.html Location is playing an increasing role in Wi-Fi networks. Most recently, Trapeze Networks announced a location-based radio frequency firewall application for its location appliance that works like a fence to prevent Wi-Fi devices in unauthorized areas – such as parking lots – from penetrating the WLAN.

John Cox 2009-06-30T12:00:00-04:00 http://www.networkworld.com/newsletters/wireless/2009/062909wireless2.html Wireless LANs rarely allow for simple direct cost comparisons. In addition to variable pricing structures among vendors, one reason is that product architectures differ. That means some systems have different components than others. So how can you compare them, tit for tat? Joanie Wexler 2009-06-30T12:00:00-04:00 http://www.networkworld.com/newsletters/wireless/2009/062909wireless1.html Recently I conducted some comparative research on how Wi-Fi vendors price their wireless LAN systems, and it was quite an eye-opener. There are notable variations among vendors, for example, as to what they include in their basic systems and what they charge extra for.

Jim Duffy 2009-06-22T12:00:00-04:00 http://www.networkworld.com/reviews/2009/062209-wlan-site-survey-test.html The pre-installation site survey has long been a core element of wireless-LAN deployments. The concept is simple: set up an access point, and, running a site-survey application on a mobile computer, walk around, noting signal strength in various locations in order to build a coverage map.

Craig Mathias 2009-06-22T12:00:00-04:00 http://www.networkworld.com/reviews/2009/062209-wlan-site-survey-bvs-test.html BVS's Swarm (most of their product names have an insect theme) is actually a set of applications that implement a fairly complete site survey tool. The first, Projector, imports and scales floor plans, and also places walls, windows, doors, and APs, among other radio and passive objects, in the model. Craig Mathias 2009-06-22T12:00:00-04:00 http://www.networkworld.com/reviews/2009/062209-wlan-site-survey-ekahau-test.html Ekahau is best known for their real-time location and tracking (RTLS) products, but they're also in the site-survey business – in fact, one of the key applications for Ekahau Wireless Site Survey is to assist in planning and deploying an RTLS installation, which requires precise calibration for optimal accuracy. Craig Mathias 2009-06-22T12:00:00-04:00 http://www.networkworld.com/reviews/2009/062209-wlan-site-survey-motorola-lan-test.html LANPlanner is a direct descendent of one of the original WLAN predictive tools from RF modeling pioneer Wireless Valley, acquired by Motorola. This is a very robust product, and, like all planning tools, perhaps a bit intimidating to non-engineers. Operation, however, is straightforward, and includes both predictive and analytical capabilities. Craig Mathias 2009-06-22T12:00:00-04:00
