    • 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.

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,

Ultimate gaming rig

The finished Big O features a PC, Xbox One X, and PlayStation 4 Pro cooled by a custom CRYOGENIC hard line liquid cooling system controlled by the PC. A Nintendo Switch dock is accessible via the front of the system just by opening the front panel, and just like a normal dock, you are free to remove the console at any time.

Wisps getting it done

Several times a year, Paul Conlin barrels up a steep, wooded hillside in his mud-green Rhino SUV to the top of Rattlesnake Mountain above Hume, to perform maintenance on his equipment, which puts homes scattered in the valley below on the internet superhighway.
