Cisco OEM’s a 5 GHz PTP radio from Exalt. Old news. If they bought Exalt, that’s news to me, but I don’t think so.

Exactly the same with the Trango ApexPlus which also did ATPC before it did variable power. They then later adapted ATPC to provide variable power. Exalt could do the same.

It's actually a lot easier for the manufacturer to design the link with a fixed +18 or +19 Tx power, than to do the feedback loop and control system needed to properly and reliably implement ATPC based on RSL thresholds on the other end radio. How do you know it definitely does support higher tx power at lower modulations (you want +22 at QPSK 3/4???), it's entirely possible the radio itself was designed from the beginning as a fixed +18 Tx power. In any case this should be a moot point with a 2 mile link.

The ExtendAir G2-18 would be a good fit. We have a link at 2.5 miles on Radiowaves HP2's at both ends. It has held up surprisingly well in the rain. 2 to 2.5 mile AF24 links in the same area drop. I guess the -34dBm RSL helps. Yes, it dropped to -70dBm, but still maintained the required 100Mbps FDX. You get single unit sparing with the replaceable/rotate-able diplexer. They're 802.3at and use about 26 watts. You get ACM without a license key. They come with a base 25Mbps license. If the promo is still going, you get 100Mbps keys with it. I don't remember if there's a 200 or 250Mbps or if you have to go from 100 to the full 370. The one thing that Ken and I have both asked Exalt for, which at this point I expect will never happen, is power per mod level, aka variable power. All you get is fixed power with ACM on. IIRC, 18 or 19dBm for 18GHz and 21dBm for 11GHz at 256QAM. The radios definitely do support higher power at lower modulations, so they're either stupid or lazy. No coordinator will even bother with variable power on the PCNs. We tried and got objections stating that "the radios don't do that". Exalt kept saying it's coming in future software, yet here we are two years later and nothing. On 12/9/2016 2:47 PM, Adam Moffett wrote: A lot of manufacturers to pick from.... With licensing and a spare radio/dish, I'm thinking $9,000. You could talk about other companies' unlicensed 24ghz options and compare apples to apples. ------ Original Message ------ From: "Eric Muehleisen" <[email protected] <mailto:[email protected]> > To: <mailto:[email protected]> "[email protected]" <[email protected] <mailto:[email protected]> > Sent: 12/9/2016 2:31:13 PM Subject: [AFMUG] microwave pricing 2 mile 18ghz link. Only needing about 150mb/s speeds. 2ft. dish maximum. Five9's. Rainzone K. Need a quick and dirty, ballpark idea of costs including licensing and spare radio/dish. Need to price it against an AirFiber24 install.
