As title says, I have upgraded two new ePMP1000 5GHz Connectorized Radio with Sync to 4.7.0.1. My understanding from this post, [GPS Firmware AXN\_5.1.\_8174](https://community.cambiumnetworks.com/t/gps-firmware-axn-5-1-8174/85760) , is that the bundle should include the GPS firmware. However it is not. Any help would be appreciated.

Hello @Matt_Allen,  
could you tell me which GPS FW version is there now?  
Depending on GPS chip version there can be different FW and version accordingly.

Products affected ePMP1000 ePMP2000 ePMP3000 ePMP3000L Background GPS synchronization is one of the most effective ways to limit self-interference. GPS synchronization allows all APs to share an accurate timing reference so that all can transmit and receive at the same time. With GPS synchronization the network can scale to significantly larger sizes without any AP’s transmission interfering with the rec…

Also you can PM me a techsupport file from the radio. I can take a look at all together.

There is GPS firmware bundled with the firmware as a package, first you must update the radio, then it will tell you if your GPS chip has an available gps update and will provide a way to update it.

Which gps firmware on which radio exactly, need the hardware ID not the mac or serial number.
