Re: [WISPA] MT power supplies THE SOLUTION
Regarding cable That makes since. We really like the Arc wireless cable because it meets the need for 70% of the CPE side installs (residential and small business) with ease of use and the right price. The industry really needed a product like that. But the ARC cable is what it is, and is no substitution for high grade cable when it is needed. The Superior Essex we use now, has been proven to be awesome. We use it the other 25% of the time, when we have long runs or have to extend across gravel flat roof (where there is risk it will be submerged in water or walked on.). Many don't realize that it is not just the metal shielding that gives isolation from interference (environmental or self induced crosstalk). The non-metalic outer jacket and inner jacket of the wires also have isolating characteristics that contribute. There is something to be said for total thickness of a cable.

Re: [WISPA] MT power supplies THE SOLUTION
Additionally consider, just because something works on the ground doesn;t mean that it will work up in the air, for two reasons. 1) When operating outside of specs, it may take a period of time before the equipment starts to fail and flaws show up. (heat build up, or stress on devices) 2) Interferences stretched along the tower structure for 250 feet, may be different than interferences that exist in a coil at the ground. Take note, that even though COILS can degrade signal, I've tested 500 feet cables on the ground in coils with Trango successfully, but up on a roof, failures at 200 feet in some circumstances. So... first, do the math. second, test on ground. third, prey that it will works after its been installed on the tower. :-) The most important lesson, is to rule out unknowns before you install on the tower. Test IP configurations of radios from laptop. Use patch cables that will be used when testing live. Work with a set of knowns. So you don't have to Climb just to rule something out. And always test before you climb down.

Re: [WISPA] MT power supplies THE SOLUTION
I started with RB 532 on tower. It comes down 265 feet to poe injector to router. Major packet loss. 2) switched RB 532 out. No change. 3) Created test setup on ground with "bad board" and it looked fine. (from laptop--6ft cablepoe265 ft---RB) 4) Blamed it on the cable, and got a cable certifier from a friend. 5) Right before climb, I re did the test setup on the ground. This time I plugged the 265 feet into the actual router instead of my laptop. The problen was back. (I was bummed) 6) One final test. Get another 265 foot cable. I used 265ft for power and 265ft for data to eth 2 or 3. Problem solved. I can only speculate that the chipset on RB 532 poe port is diffrent from the chipset on eth 2/3. And for whatever reason it was not compatable with cable, hardware, ect.setup. I may never know for sure why, but I have the workaround. Good enough for me. FWIW I ended up pulling 2 new cables (all 3 certified fine). I used the original cable for data (it has "real" shield) I used my new 2 (cheapo foil shield) for power and slapped the other into eth3 for the heck of it. Lessons learned for next time. Measure cable, crimp, and power up on ground using the EXACT same everything as what the final deployment will have. And then test. Hope that sums it all up. Ok to directly answer your question. Yes. I did this on the ground test unit. Brian Rohrbacher Paul Hendry wrote: Brian, Just out of interest, did you try running both power and data over the new cable and did you still see the same issue?

Re: [WISPA] MT power supplies THE SOLUTION
I was on 48v from the start. But I tested 4 48v power supplies300, 420, 700, and 1000mA units. None of that had any effect. The seperate cables. One for power, one for data fixed it.

Solution has always been to increase the voltage to reduce the amperage to control voltage drop. That is why you see transformers all over the place. I like 48 Volts a whole lot more than 24 volts.
