InfiNet Wireless R5000 Technical User Manual

The top of the Input Signal stripe can be located in black (Good signal) or red

(Bad signal) background areas or somewhere in washed border between them.

It means the signal is good, bad or average correspondingly. When aligning the

antenna it is recommended to try to achieve the stripe top to be located in the

black area.

At the bottom of the Input Signal stripe may appear a special red sub-stripe. This

sub-stripe indicates the presence of packet retries and its percentage of the total

transmitted packets number.

During alignment test the Input Signal stripe may be moving along Cross Fading

scale and increase or decrease in height indicating the changes in the received

signal. When the top of the stripe is changing its location moving from one point

on the background area to the other it commonly leaves pink and blue marks

that indicate measured maximum and minimum levels of the signal at the

particular point. Thus it makes possible to observe the ―history‖ of the signal

changes. To clear the marks use ―Clear History‖ button at the bottom of the

page.

Main recommendations when using ―Antenna alignment tool‖:

1. It is recommended to start antenna alignment with searching maximum

signal level on a minimal possible bitrate. Afterwards automatic MINT

mechanisms will set the most appropriate bitrate when “Autobitrate” mode

will be enabled.

2. Input signal level should be between 12 and 50. ATPC is recommended to be

enabled.

If signal level it is more than 50 it is recommended to lower amplifier power

(ATPC will do it automatically).

If maximal signal level is less than 12 it is recommended to lower channel

width (for example, from 20MHz to 10MHz).

In some cases signal level that is less than 12 may be enough for radio link

operation. In this case one has to be guided by such parameters as number

of retries and Error Vector Magnitude. If the number of retries is small and

EVM is more than 21 (Input Signal stripe is green) then the radio link, most

often, will be operating properly.

3. Retries value should be zero or as low as possible.

4. The top of an Input Signal stripe should be located in the black area.

5. The signal quality should be good: EVM value should be more than 21.

6. Input signals of the two antennas of the device should have similar Cross

fading values (Input Signal stripes should be located symmetrically relating

to the 0 dB value).

ALL described recommendations are applicable to both (Local and Remote)

sections.
