Veriwave's WaveDeploy Raises the Bar on WLAN Assessment - Page 2

The Fine Print
Despite these benefits, WaveDeploy has a few limitations. For starters, large volume client "what if" testing won't be convenient until WaveDeploy WiFi hardware is released. First-generation WaveDeploy WiFi will only simulate SISO clients; a second-generation MIMO unit will be produced later this year.
Additionally, WaveDeploy is a measurement tool, not a predictive planner. Floor plans are just drawings; a configurable "radius of influence" determines how far each measurement is used for interpolation. If no measurement was taken close to a spot, it appears as a void on the heatmap. Furthermore, because WaveDeploy does not consider the impact of building materials, interpolated results around the corner from a sampled spot could be off.
Finally, WaveDeploy surveys can be repeated to validate fixes or verify expected SLAs. But WaveDeploy is not a continuous measurement or service assurance system; it cannot alert you to changes or automatically adjust your WLAN. But as Mathias suggested, "It's not hard to see management or assurance tools (and sensors) incorporating this functionality over time."
See for Yourself
Veriwave is releasing WaveDeploy Basic as a free download at www.wavedeploy.com. Basic can be installed on a Windows laptop to measure three metrics (RSSI, interference, and TCP throughput) for any local Wi-Fi adapter. This free program cannot measure other kinds of clients or applications, but it can still be useful -- and give potential customers a feel for WaveDeploy.
Later this summer, Veriwave plans to ship WaveDeploy Expert, capable of measuring traffic sent through up to 300 client devices (live and/or simulated by WaveDeploy WiFi). Price depends on number of WaveDeploy WiFi units. Expert will offer added benefits to larger enterprises and integrators that need to perform "what if" analysis on larger, complex, mission-critical WLANs.
