Kurt This is a good point, the CPEs are all sending a signal back to the AP at random times but as you scale more are hitting at the same time which can over load the receivers on some AP radios. When you lower the power on the units that are closer this reduces the total power levels the radio

I have already emailed Mikrotik a week ago, and opened a new thread on their forum. They should at least get the idea of what I need and develop a test that is specific to their wireless. I do NOT want this to turn into a year long project. Travis Tom DeReggi wrote: Butch, You have

Tom, One thing I did when I was building StarOS radios was use one mounting screw per board. Partly I was doing that because I thought the board should be grounded to the case, but it also would have helped if the glue failed on the plastic standoffs. Also, I'm not sure what the bad

I've used them for a few years now and can't recall seeing any of the larger sized bases come unglued from the enclosure. I use these everywhere, all I use is boards and rootennas. The ones that have failed are the skinnier small based ones. I've seen that when it got too cold inside a nema

One nice thing about the new 4 ports in the enclosure, they use the metal standoffs we are suposed to be using, so it's grounded like you said in various spots on the board. John Valenti wrote: Tom, One thing I did when I was building StarOS radios was use one mounting screw per board.

I was looking around for a method to keep at least my backbone running during an extended power outage. (we have had ice storms take out power for 4 - 7 days). It seemed like the small generators might be a solution, the Honda/ etc name brand ones seem to be ~$600 for 1000 watts. And I found

If you are powering anything but a rectifier to charge batteries, look for a generator with inverter technology such as the honda EU series. Most portable generators don't have the voltage or frequency regulation stability to keep UPSes or sensitive electronics running. Inverter generators
