SUBJECT:uGPS Connectivity Issues in APAC and Russia

MODEL / SYSTEM AFFECTED:    1096H (Universal GPS Module) deployed only in the region highlighted by the red arrows on the map in the attached file.

REASON FOR SERVICE:    Interference from a satellite launched in the second half of 2017 is causing interference with some GPS receivers throughout the Asia Pacific and Russian regions. In particular, certain Cambium Networks uGPS units, deployed in the regions, periodically lose their connection to the GPS satellite network and thereby cannot provide the 1 PPS signal needed to synchronize Access Points.

RESOLUTION:    A firmware update to fix the issue is now available. This fix requires the uGPS unit(s) to be returned to an Authorized Cambium Center for the firmware update.  If you are experiencing uGPS connectivity issues on a device deployed in the region within the red box above, please go to https://support.cambiumnetworks.com/ and open a support ticket with the subject “uGPS Update.” Cambium Support will help you determine if the unit is impacted and provide you with a process for returning the uGPS unit(s) for this firmware update.
