Cambium is officially releasing the PMP450x Radio 16.2.3 software. It is the initial release for MicroPop and Retro hardware, and also a bug fix release for CBRS and all of 450 series.
- Radio software and documentation can be found at https://support.cambiumnetworks.com/files/pmp450/.
- CBRS procedures that involve both cnMaestro and radio software can be found in the cnMaestro repository at https://support.cambiumnetworks.com/files/cnmaestro/.
16.2.3 will be available on cloud cnMaestro within 24 hours.
Problems and Limitations Corrected in 16.2.3
|All CBRS||CPY-16835||Modified handling of CBRS 400 response code in a grant response. When a radio requests a higher EIRP than previously authorized on FW SAS, and SAS responds with a 400 grant response suggesting the previously authorized lower value, the radio will now send another grant request with the previously authorized lower value.|
|CBRS with Domain Proxy||CPY-16829||Difficulty establishing CBRS AP to Domain Proxy connection when upgrading to System release 16.2.2. This fixes a problem when using cnMaestro as an HTTP proxy for CBRS messaging as documented in field service bulletin FSB9082|
|All 3.6 GHz||CPY-16843||Re-allow scanning of 3.6 GHz 7 MHz in FCC region (can be used by operators with CBRS disabled)|
|450||CPY-16142||450 SM reporting SNR on the wrong path|
|450m||CPY-16864||Session drops with 450m and heavy downlink broadcast or multicast traffic.|
|All CBRS||CPY-16871||SMs sometimes not adjusting power after enabling CBRS|
|450 AP||CPY-16854||PMP 450 AP resetting due to BufNum/Head mismatch|
|450 AP||CPY-16735||PMP 450 AP Reset due to MPU Violation|
|450 AP||CPY-16580||Multiple MPU violation error crashed across two APs at the same time.|
|All||CPY-16816||Unable to claim device in cnMaestro due to serial number on device did not properly terminate.|
|All CBRS||CPY-16823||Update grant expire time. Grant will now be renewed 24 hours or 1 week prior to the Grant Expire time, depending on the SAS vendor, rather than a few minutes prior as was done in 16.2.2 and previous releases|
|450b PTP and MicroPoP||CPY-16585||For 3 GHz 450b PTP and MicroPoP units, the SES/SYN LED falsely indicates sync when “Free Run Before GPS Sync” was disabled.|
