wireless network devices (routers, access points, etc) in
network emit radio waves which your wireless devices (computers, smart
phones, etc) receive. We call this the WIFI Signal.
stronger the signal, the faster your network is. WIFI Signal
strength varies based on many factors, such as:
- Distance from devices (measurement from a wireless
access point to a laptop)
- Physical blockage of signals (walls, floors, furniture,
- Radio interference (conflicting signals from multiple
wireless access points)
- Wireless access point configuration (various settings on
In order to acheive maximum performance from a wireless network, you
must first quantify, or survey
the network's current performance. This survey must include
signal strength at all locations of interest. Once the signal
strength has been measured, we examine the
factors that are
causing weak spots and we measure the data
throughput between certain devices on the network.
the collective information in the survey, the network devices can then
be re-configured, re-positioned or otherwise improved with additional
equipment. The improved network will again be surveyed to provide a
The survey is done via first
drawing a plan (or utilizing an existing plan) of the particular
building or site. Special equipment is then used to measure
map the signal strength onto the plan.

WIFI Survey maps show the before and after signal strengths of a
particular floor in a residence. Webbstar was called in to
improve the signal strength on all the floors as well as the grounds.
The after map for this floor shows a marked improvement

wireless router with properly located access points.
