Trio Q Radio - Dynamic Beacon

I believe the latest firmware on the Q radio has this feature

 

In the Modulation section,

a. From the drop-down list for Dynamic Policy, select ARQ.

b. From the drop-down list for Dynamic Beacon, select Master.

 

Will changing the dynamic policy to arq affect how it preforms? My radio was setup with RSSI as standard.

 

Does the Dynamic ID just identify which site is replying back to the basestation?

Re: Trio Q Radio - Dynamic Beacon

Note first that these comments refer to Trio Q firmware 2.2.5.6746 or newer, when installed in ETSI-type radios. QAM and the related features will be available in the very near future for FCC-type radios.

 

Dynamic Policy and the related features have a significant amount of "Help" in the web browser if you click the "More help..."  blue link by each item. Also, this topic is discussed in some detail in the Trio Q user manual, which will be installed on your computer when you install the TView+ Management Suite software package.

 

This software can be downloaded from the se.com website. Go to Products, then Telemetry and Remote SCADA Systems, then scroll down to Data Radios and select either the Licensed or License-Free radio type. On the page for your radio type, select the Software and Firmware tab, and TView should be near the top.

 

On page 44 of the December 2019 version of the Q user manual there is quite a bit of information about each option for Dynamic Policy. Near the bottom of the page, in the ARQ section, the manual states:

 

When the Dynamic Policy is configured as ARQ, the RF data rate selection by the radio is
determined by the ARQ retry rate. If the currently selected RF data rate is too high to support
reliable reception of transmitted packets, ARQ retries will be required and the packet
retransmitted. ARQ retries are transmitted at progressively lower speeds to ensure delivery. The
aim of the algorithm is to choose the optimum RF data rate of the initial packet transmission and
maintain an ARQ retry rate of between zero and 1%. This policy is only available in QAM mode...

 

The Beacon ID is used by Remote radios to ensure they are following the beacon of the correct Master radio, as it is possible there could be more than one Master that the Remote radio can hear.
