Max EIRP C5c United States


#1

Does the C5c follow PTP rules for max EIRP? I am testing a unit on a shot that has some trees/LOS obstructions so I’ve hooked up a 22db gain dish to it. Depending on what I set the gain to I can only get +40 out total. I’m running 2.4.0 on both the A-14 and the C5c. Any thoughts?

As far as I can tell Mimosa takes pretty special care to make sure they are following the rules for EIRP.

That said, you wont get P2P power using an A5-14 because that is a P2MP (Point to Multi Point) product. You will have to go C5c to C5c (with the P2P software on both) or use a B5 link to get P2P EIRP.

The PTP firmware for the C5c does follow the EIRP limits for the country it is operating in. In United States, these are the PTP EIPR limits:

5150-5250: EIRP 53 dBm, OOBE EIRP ~40 dBm
5250-5350: EIRP 30 dBm, FCC radar
5470-5725: EIRP 30 dBm, FCC radar, 5600-5650 blocked due to TDWR
5725-5850: EIRP unlimited, OOBE EIRP ~40 dBm

It is also a good idea to model you link in the Mimosa Design tool, and see the received signal you are getting compares to the Design tool prediction.

What about PTMP? I’m running my C5C on PTMP firmware connecting to an A5-14

Then you will only get the PTMP EIRP.

Mimosa’s design tool can do the modeling for A5-14 to C5c as well, but I doubt the C5c will connect to the A5-14 with the PTP firmware.

P.S. It is PTP not P2P, I am incapable of using the correct acronyms apparently.

Here are the EIRP limits for PTMP in the United States.

5150-5250: EIRP 36 dBm
5250-5350: EIRP 30 dBm, FCC radar
5470-5725: EIRP 30 dBm, FCC radar, 5600-5650 blocked due to TDWR
5725-5850: EIRP 36 dBm
