SU Alignment Using LEDs
The LED RSSI indicators on the bottom of the radio provide a handy alignment tool. If all four LEDs are lit,
the unit is receiving –64 dBm or stronger. If no LEDs are lit, there is not sufficient signal strength to establish a
wireless link.
Lit LEDs Signal Strength
0 LED -80 dBm
1 LED -75 to -79 dBm
2 LED -70 to -74 dBm
3 LED -65 to -69 dBm
4 LED -64 dBm and stronger
Collocation and Channel Planning (temporary example from 900 manual)
With proper channel planning and adherence to installation guidelines, multiple M900S access points may co-
exist and operate interference-free on the same tower or building. The main consideration when collocating
access points is to ensure at least 10 ft. of vertical separation. Please see the diagram below for collocation
spacing and suggested channel plan.
Note: RSSI tool (telnet or LEDs) will show all RF
energy on a given freq. i.e. – a nearby SU on the same
freq. passing traffic may give the appearance of a
strong signal from your AP when in fact it is not and
cause a misalignment.
