Cambium networks on Mt. Everest

Ever since my dad and I went to a slideshow (yes I said slideshow) at a dinner years ago I have always been fascinated with Everest. I am not one to want to climb it.  But the lore and “behind the scenes” of climbing is pretty cool.

Many folks think the numbers of people at the Everest Basecamp are few and far between. The below photo from an article about Cambium equipment providing wireless to the folks at Basecamp shows the sheer numbers of climbers ascending Everest each year.

One of the most prolific things I remember in the slideshow was the presenter saying after he was on the summit of Mt. Everest.  After a few minutes of taking it all in, he had a realization.  “I didn’t have to climb this mountain, but I have to climb down!”

What Everest Basecamp is like:

ePMP 3000: How to test MU-MIMO

http://community.cambiumnetworks.com/t5/ePMP-3000-MU-MIMO/ePMP-3000-How-to-test-MU-MIMO/m-p/102882

Intial MU-MIMO testing after deployment can be performed through the built-in Wireless Link Test Tool.On Wirless link Test page new option has been added for ePMP3000 – Mode. Wireless Link Test can be started to Single SM or to Dual SMs simultaneously.

ePMP tip of the day

ePMP GPS Sync Radio devices that have an onboard GPS contain two banks of flash memory which each contain a version of software.

The version of software last installed onto the device flash memory (using software upgrade procedures) is configured in the Active Bank. This software will be used by the device when the device is rebooted.

ePMP eDetect

One of the biggest tasks on a wireless AP is finding clean channels.  Once you find those clean channels, making sure you stay on a clean channel is the next task. ePMP has a feature under tools called eDetect. One of the things this can do is give you an idea of how many devices are on a given frequency.

The ePMP AP you see above is on a 20mhz channel, which is why many home routers and other devices are showing up.  If this was on a cleaner frequency it would look like the following.

While eDetect is not a replacement for spectrum analysis, it can give you a pretty good idea of what’s using a particular frequency.  Please note, you see the most things on 20MHZ channels because that is what most home routers are set to.
