I put in quite a bit of wireless PTP microwave and except for rotten weather (rain fade) and cranes getting in the way (crane fade) it worked flawlessly. It used to be that 24 ghz required an FCC license but it's nice to know that it doesn't anymore.

Like brokeda said, turn the power down - but be careful. If the weather gets bad you'll lose signal. What does the system use to measure signal strength? Volts? db? I don't remember the db rating anymore, but if it's volts, then 3.5 volts would be
just fine.

I believe it is DB. The web server onboard has a basic test utility and so can set how strong it transmits.

Dumb question: Why would one turn the power down? Just as a courtesy to anyone else down the road that might be using 24ghz? Radiation?

As I said before, we are amateurs at PTP wireless. We wouldn't be taking it on if it were not for saving a homeless shelter a lot of money.

My next challenge is to find a bigger clamp. They have an existing 4" mask on one side and the one that comes with the dish will only support up to 3". Hard piece to find, even online.

The picture is the dish/unit attached to a ladder for testing.

Well, interference with other equipment is certainly an issue, but if the equipment is running too 'hot' you could burn it out.

According to the manual , it looks like you have several option in tuning the power output. Power attenuation, max power output, automatic power output (automatic gain control?), etc. Decreasing the power output would lower your noise floor and potential for interference.

Remember that radio is easy to interfere with (technically) and anyone else on 24ghz will interfere with you. As long as it is occasional, it won't cause any issues (the equipment is designed for this). But the more someone else on frequency transmits on 24ghz, the more likely you will see decreased performance.

One sure way to get someone else's transmitter to transmit more is to interfere with it, as it will then try to resend the things that didn't make it to the other end.

So...if someone else is on 24ghz somewhere around, the more power you use, the more they will transmit after being "jammed" by your noise. Their retransmissions will then "jam" your transmissions, and you'll end up getting worse performance for both parties - both you and the mystery 24ghz user. So it's in your best interest to not overpower the neighbors, as then their system won't need to transmit as many times to send one piece of information (because you didn't overpower it).

Thanks guys! Will do.

Please start a new topic for your problem.

Try using an Ayrstone. I am sending signals over 1000 feet with very little db loss.

https://www.ayrstone.com/

That Ayrstone is perfect for just supplying internet-only connectivity over a large 360-degree area. It isn't really like a WAP for a private network sharing devices though. Plus, a building to building link - directional connection - in a 'clear path' enviroment would probably be better served with the Trendnet.

I will remember the Ayrstone especially for businesses wanting to supply a public wireless connection like a coffee shop, etc - nice range!

The Ayrstone isn't uni directional but you can connect two (or more) of them together. The second one can be plugged into a switch and then "wired" devices can be on an extended lan and/or wan.
