Spinwave Systems, Inc.

Site Survey Tool, SWSST

Type:  Misc. Hardware
Description:  Spinwave Systems' mobile Site Survey Tool allows users to easily test the RF link quality and signal strength at desired sensor locations prior to installation. The Site Survey Tool takes the guesswork out of your quotes and installations. Pushing the survey tool's button will establish a communication link with the closest receiver module. The survey tool's LED and blink pattern will indicate the link quality and signal strength of the 4 best RF channels among all 16 available IEEE 802.15.4 channels. The LED's color will be a solid green for excellent links. A green blinking LED indicates a good link. The LED's state will change from a steady orange to a blinking orange for marginal signal strength and turn to solid red for out of range conditions.
