2.8 RSSI LED Indication

For easily configuring A-6000 radio status, 3 RSSI LED are designed in IDU to indicate radio RSSI status. The

following mapping table explains the meaning of RSSI – “L”, “M”, and “H” LED signal status.

RSSI (dBm) L M H

<= –65 Off Off Off

-65<RSSI<=-60 Flash Off Off

-60<RSSI<=-55 On Off Off

-55<RSSI<=-50 On Flash Off

-50<RSSI<=-45 On On Off

-45<RSSI<=-40 On On Flash

RSSI>-40 On On On

2.9 Alignment Tools

While easily adjusting directional antenna, we design alignment tools to indicate radio signal strong or not. In alignment

tools, we use Level to display current RSSI status and design beep in different frequency to represent different SNR value.

Following two tables are Alignment Tools Level value mapping with RSSI, and Alignment Tools vs. SNR mapping table,

respectively.

Alignment Tools Level vs. RSSI :

RSSI (dBm) Level

-90 0

… (RSSI+90)*2

-45 90

Alignment Tools vs. SNR :

Beep Frequency SNR (dB)

0 SNR< =25

0.975Hz 25<SNR<=30

1.95Hz 30<SNR<=35

3.9Hz 35<SNR<=40

7.8Hz 40<SNR<=45

15.6Hz 45<SNR<=55

31.2Hz 55<SNR<=60

∞ SNR>60
