Microflex AV/ADV/AVr/ADVr North-American user’s manual / Rev 1.4

The Microflex in master mode continuously transmits a beacon (at 10 msec
intervals) to remote stations and this, whether or not, the data or audio port is
active. This beacon provides a good signal for RSSI measurement at each
remote station.

To conduct the remote site survey proceed as follows:

STEP 1.

Install the proper antenna at the remote location proposed

STEP 2.

Connect the Microflex configured as a Slave to the antenna

STEP 3.

Align the antenna to obtain maximum RSSI

STEP 4.

Note the RSSI value

____________________________________________________________________________

If the RSSI bargraph does not reach the third LED indicator at low bit rate and the fourth
indicator at medium bit rate, there might be insufficient margin to guarantee a
continuous high quality link (BER > 10

-5

). Considerable temperature variations and heavy

rain can cause path loss variations of up to 3 dB. There are two (2) options to decrease
path loss:

1) Increase the height of the base / repeater or remote antenna, or

2) Increase the gain of the antennas used (within the 11 dBi limitation, including cable
losses).

If these options are not feasible, a repeater station may have to be installed strategically
along the path.

3.1.5 RF Exposure Considerations

In order to comply with the RF exposure requirements of CFR47 1.1310, the
S1000 must be installed in such a way as to allow a minimum separation distance
of 10 cm (4 in.) between antennas and persons nearby.
