Importance of PIM in LTE

As the number of WISP LTE deployments increase, there are many things WISPs will need to be mindful of.  One such item is properly supporting antenna cables. LTE systems are more sensitive to cable issues.  In a previous blog post, I talked about pim and low-pim cables.   One of the things that can cause low pim is improperly mated cables.  If cables are not supported they can become loose over time.  Vibration from equipment or even the wind can loosen connections.

How do we support cables?
We can take a cue from the cellular industry. The following are some examples of proper cable support.  Thanks to Joshua Powell for these pics.

Where can you get these?
A good place to start are sites like sitepro1 or Tessco has a selection.

So the next time you are planning your LTE deployment think about cable support.

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.
