COMPASS Features and Functions

Updating QUATRA RED Software

From time to time, the QUATRA RED firmware is updated for feature improvements and bug fixes.

Updating QUATRA RED firmware can be accomplished in either of two ways:

1. Connect the LAN port on the QUATRA RED NU to an active Ethernet LAN. The unit updates its

firmware automatically, communicating with Nextivity's cloud.

a. Make sure the NU's Internet connection can get through the firewall.

2. Update the COMPASS software by connecting it to an active Internet connection. Connect the

COMPASS to the QUATRA NU and follow the instructions on the WAVE PRO app.

Donor Antenna Setup

 With the help of COMPASS, select a location on the roof with a dominant signal level at least

6dB higher than other signals.

 Install the donor antenna at the designated location and height.

 Verify that the antenna is pointing towards the donor site and it has a clear line-of-sight.

Connecting Donor Source

The QUATRA RED system can accept up to two individual donor signals (LMR and FirstNet), each

technology has a dedicated donor port. These ports cannot be reassigned or reconfigured. Each donor

can be established to the system via off-air. A directional antenna is recommended to provide the best

signal quality. (Nextivity offers many directional antennas that can be used. See www.cel-

fi.com/products for details).

Isolation calculation and setting

QUATRA RED automatically calculates and sets isolation according to any value given. The default

isolation value is 20 dB. To enter a new value for isolation:

1. Click on the current isolation value

2. Type-in the new value

3. Click on calculate and set

A message will appear on the screen once the system has been adjusted to the new value.

If you can't achieve enough isolation, you can try one of the options below:

1. Increase the spatial separation between the donor and the closer server antenna.

2. Try a larger value for the coupler feeding the antenna causing the issue

3. Look for a donor antenna location with some physical obstructions such as walls or columns.

4. If you're using a wide-angle donor antenna, consider replacing it by a high-isolation antenna.
