Water tower install with mounting frame

We recently headed up a job for a client of installing some RF elements horns, Cambium ePMP, and Baicells LTE for a client.  One of the gems of this job was the frame the client designed for the job.  We can’t take credit for this. We just think it’s cool. Some of these pictures were taken during construction, thus post clean-up.

The frame is truly an example of how WISPs are stepping up their installs to become more standardized and carrier-grade. It costs some money but is worth it in the end.


Quick tidbit on Cambium GPS sync source

Synchronization source– Synchronization mode supports two types of timing sources: the timing signal provided by a Cambium Network’s Cluster Management Module (CMM) or by the AP’s own on-board GPS receiver. Both these sources require GPS Synchronization capable AP hardware and will allow APs to receive a stable timing signal to synchronize their own Tx/Rx cycles.

There is a third option for the Synchronization source, namely “internal”. This “Internal” Synchronization source option is NOT an actual synchronized timing source and when selected, it just provides timing from an internal unsynchronized source. “Internal” is NOT to be used in GPS Synchronized deployments but could be used with single PMP AP installations. The “Internal” timing source is also used when the Flexible DL/UL ratio option is selected.

    • Added warranties for PTP 820F
  • ePMP
    • Add ePMP 3000L, Force 300-CSM and Force 130

These products are only available in the 5 GHz band and please note that the Force 300-CSM and Force 130 are not supported in United States, Canada and associated FCC countries.

  • PMP 450 family
    • Added notification of pending End of Life for PTP 450 and PMP 450 SM
    • PMP 450b SM changed to use the new parts which can be used for either PTP or PMP
  • General
    • Warranties – updated default warranties in line with changes to warranty options
    • Changed the best server to process in batches and report high level results at the end of each batch to show progress when analysing large projects and reduce “Not responding” issues.
    • Discontinued RF Elements SH horn antennas and added similar HG3 horn antennas
    • Added a “Highlight AP” function to the offline map which when selected will grey out all other APs and associated SMs to allow focus on the SMs connected to the selected AP.


Select the new icon, shown in the red box above and then select the AP that you want to highlight, remember that you can use the up and down arrow keys to toggle between overlapping APs to select the one that you require. Click outside the AP coverage area to return the screen to normal but leaving the highlighter enabled or click on the pointer option on the toolbar to disable the highlight function.

  • Stopped errors when deleting AP or SM from the Subscriber Site List tree
  • Force the proxy port settings to be an integer
  • Added missing power cord in PMP 450i AP BOM
  • Prevented errors when creating hub level reports
  • Ensure that HCMP Expert mode DL and UL slot allocations are loaded correctly
  • Corrected error on PTP 550 2+0 when changing regulation
  • Improved Options dialog label formatting
  • Prevent errors when changing quantities in the hub BOM
  • Corrected error when selecting the original PMP 450i integrated AP on 5.2 GHz/Canada
  • Allowed custom clutter categories to load correctly from project file
  • Mac only – Disabled Delete option on the hub using the right-click menu in the tree
  • Mac only – corrected issue preventing users from selecting antennas in the BOM Estimates and equipment templates
  • Mac only – prevent errors when clicking quickly multiple times in BOM quantity cells

Cambium ePMP compatibility graphic

Please note the following for e3K compatibility. We do not recommend or support running a mix of 3.X AND 4.X on the same sector. All APs/SMs should either be running on 3.X release or 4.X release but not mixed for commercial deployment. Standard upgrade path should still be followed,
