Question about WiTuners Spectrum Analysis Capability

Does WiTuners offer a spectrum analysis capability?

Yes, WiTuners offers a spectrum analysis capability as part of its live site survey function. It requires a calibrated RF receiver and WiTuners works with Wi-Spy DBX-pro which is widely available and does not cost a fortune. The Wi-Spy receiver allows WiTuners to display the actual spectrum conditions at a given location with resolution down to 1MHz.

How does the spectrum analysis capability help me maintain a high performance WLAN?

In the real world, Interference sources play a significant role in the performance of large WLANs deployed for professional use. The spectrum analysis capability helps you to understand what is actually happening at your WLAN site: it makes interference sources such as Bluetooth and Zigbee visible and it is able to display self-interference caused by external WLANs and by hidden node effects within your own WLAN. This information is taken into account by the WiTuners Optimization function so as to minimize the interference impact, regardless of its nature.

Why is true 3-D RF analysis so important?

RF signals propagate in three dimensions through and around objects, walls and floors. Therefore, only 3-D RF analysis can determine RF coupling and interference with sufficient accuracy to yield a truly optimal RF plan for a WLAN network. Most buildings have multiple floors and although many types of floor attenuate RF signal heavily, even the relatively low power RF signals of a WLAN network penetrate to other floors. In older buildings with wooden floors these signals may carry over 3 or more floors. WiTuners is unique in that it applies WLAN interaction analysis in three dimensions and over multiple floors.
