With an SR5 card in one box with a 23dBi panel and a CM9 in another box with a 19dBi PacWireless panel both running 2.9 the connection drops on heavy upload traffic. Both sides are set to connect at no higher than 24Mbps and download transfers exceed 8 Mbps but once a heavy upload starts the connection drops. Any ideas?
If you’re running an SR5 at 24Mbits, are you sure it’s getting its full 5W of power?
We have a 20 Watt 1.2A power supply connected with a 180ft shielded cat5 run. Just the connection is lost, nothing reboots or shuts down.
Ok, that answer tells me you didn’t understand the question. An SR5 card can draw slightly more than 5W of power at 3.3V from the miniPCI slot it is plugged into, worst case. A lot of systems can’t supply that much power and what you’ll see is the card go unstable under heavy xmit, which is the time of max power draw.
It isn’t so much the power you’re pushing up the CAT5, it’s how much of it is available to the card when it needs it. The first is important, but the later is critical.
Try adjusting the xmit power of the SR5 down to 300mw and see if things become stable. If they do, you’re probably chasing a power limitation of the board you are using. You might mention what board you’re using also, some are known not to work and others are marginal.
The client that disconnects on transmit is the CM9 radio, not the SR5. So, the SR5 shouldn’t have any power problems. The SR5 is in a RB532 so it’s not an issue of the SR5 drawing too much power. Downloads from the SR5 to the CM9 work fine.
Yep, now what you’ve given us a better picture of the setup, it doesn’t sound like a power issue so I’ll let somebody else make suggestions now.
I have experienced the same - on ATX machines (celerons/p2 ~400MHz, 256MB RAM, i440BX chipset, powered directly from normal power plugs). This is reproducible for me and seems to be problem in software, we use nstreme/exact-size and dynamic-size, framer-limit set to 4000 (max), clean RF environment, very short distances (1km, signal around -60db), cm9.
Everytime we start to transfer around 50Mbps total (either unidirectional or fullduplex together), CM9 cards are not behaving good.
Radio cards getting hot?
High TX duty cycle should make them up a bit more I think.
Less likely if your case is indoor and fan cooling.
Just a thought …
