Veriwave has primarily focused on building Ethernet and 802.11 wireless test equipment for carriers and equipment manufacturers for quality assurance, test and development. WaveDeploy is Veriwave's first enterprise-focused product and builds on their experience in 802.11 wireless testing. Traditional site survey tools that measure radio frequency characteristics such as broadcast power and channel interference and provide an assessment of quality are based on a series of assumptions that may or may not manifest in the real world. By simulating devices and traffic types like HTTP, voice over WLAN, and streaming media, WaveDeploy can see how applications are behaving on a live network.
Unlike other spectrum analyzers offered by Cisco Spectrum Expert, Air Magnet and Ekahau that require specific hardware cards for analysis, WaveDeploy can use any wireless card. That makes client support easy for the two software only models WaveDeploy Basic and WaveDeploy Pro.
WaveDeploy works by using a network server attached to the wired network and a software client in WaveDeploy Basic and WaveDeploy Pro or a hardware client in WaveDeploy Expert. A floor plan is loaded and scaled to the WaveDeploy grid. Administrators then take the agents around the floor plan taking measurements and marking on the floor plan where they are standing. This is typical for a site survey. WaveDeploy's tests, however, go beyond RF measurements by testing for TCP and UDP goodput, which measures the amount of successfully delivered data, streaming voice and video MOSS scores and other application metrics. The result is what the company calls a quality of experience measurement from the user's perspective.
Victoria Poncini is a wireless IT architect with Microsoft and manages the company's global wireless network of 15,500 access points, 450 controllers, and over approximately 100,000 users worldwide. "We want to create pre- and post-deployment surveys that we use to create SLAs and for troubleshooting. We currently use spectrum analysis for the site survey, but that doesn't allow us to simulate multiple clients with different chipsets and software stacks nor get a good feel for application performance over the WLAN. We have had trouble with real-time traffic like voice, video and multicast traffic over 802.11a/b/g WLAN network. It's going to be an issue as we migrate to 802.11n. In our testing, we found that WaveDeploy performance closely matches real-world client experience."
