Abstract
The invention provides a method of determining the effectiveness of radio communication over an area covered by a wireless LAN. A value of a signal parameter, such as stability or throughput, is detected at each of a plurality of sample points spaced over the area. The variation in the parameter over the area is shown in colour on a display.

A method of determining the effectiveness of radio communication over an area covered by a wireless LAN, comprising detecting a value of a signal parameter at each of a plurality of sample points spaced over the area, representing the area on a display and showing on the display a representation of the variation of the parameter by interpolation between the detected values, whereby the viewer of the display can determine the effectiveness of radio communication over said area.
A method of illustrating the effectiveness of radio communication over an area covered by a wireless LAN, comprising detecting a value of a signal parameter at each of a plurality of sample points spaced over the area, representing the area on a display and showing on the display a representation of the variation of the parameter by interpolation between the detected values.
A method according to any of the preceding claims, wherein the interpolation is linear.
A method according to any of the preceding claims, wherein the signal parameter is throughput of data or signal stability, the latter being representative of the variation of received signal throughput from an average throughput.
A method according to any of the preceding claims, comprising detecting the values of two signal parameters at each of the plurality of sample points and showing on the display a representation of the combined variation of the two parameters.
A portable computer serving as a site survey tool and programmed to carry out the method of any of the preceding claims.
