When the highest degree of accuracy is required for your mission-critical applications, there is no substitute for a professional-grade manual site survey. Only by thoroughly sampling for not only signal strength, but signal-to-noise ratio, interference, along with data rates and throughput, can problems be identified such as: deadspots, co-channel interference from internal and external access points, and not having enough capacity per access point.Without gathering the correct information and then knowing- through extensive training and experience- how to make the necessary adjustments or recommendations, a wireless network design that can reliably support latency-sensitive, mission-critical applications is nearly impossible to achieve. Our pre-installation wireless site surveys start with temporarily mounting the same access points and antennas that will be permanently installed, as determined through a predictive model. Without using the same hardware that will be permanently installed, designs can easily be based upon false conclusions leading to unreliability. Just about everyone with a wireless card and netstumbler claims they can perform a wireless site survey. Before choosing a vendor, make an educated decision and find out what kind of tools, experience and training will be used. Do they have a methodology or organized approach, and what references can they provide?
