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.

PTp550 Throughput with RF elements horns

Distance:5.03 Miles
Downlink RSSI: -59
ChannelWidth: 40MHZ
DownlinkSNR:33bB
Antennas: RF elements Ultra Horns
Downlink Ratio set to 75/25

Question: Why are you not using channel bonding? 
A)Having some reliability issues with channel bonding at the moment on the 550 platform.

Question: What was the link like before the horns?

Dmitry from Cambium talks ePMP 3000 antennas

Folks,

For some reason when I moved the blog to a new server some of the media did not move over right.  As a result, I am re-posting some of the content on the j2sw blog.

 

I was able to sit down at WISPAMERICA and talk with Dmitry from Cambium about some of the misconceptions of using 3rd party antennas with ePMP 3000.
