Mount Sapphire Eye in the most centralized location of the WLAN area. Eye can be installed on
the ceiling, wall or mast.
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: Eyes must not be located too close to any metal objects and places
surrounded by concrete walls.
The best installation location is easily verified with:
 Site Miner: The Site Miner kit includes a Carat laptop and an Eye unit (with battery).
