6 INSTALLING EYE
Install Sapphire Eye in the most centralized location of the Wlan area.

Sapphire Eye has extremely sensitive radio technology inside
The receiving signal is 10-20dB stronger than the basic Wlan end-user
The transmitted signal is 5-6dB stronger at the access point side than with the basic
Wlan end-user
For best accuracy of the Wlan performance, the Sapphire Eye location should be selected so
that:
The average signal level for the managed Wlan access points are between -65dBm and
-30dBm
NOTE: The bad performance area is not necessarily the best Eye location.
The best installation location is easily verified with:
Portable Sapphire kit. The kit includes a Carat laptop and an Eye unit (with battery).
