Re: [AFMUG] Higher power 18Ghz radios..

I’ve used the layer 1 capacity from the Aviat and Dragonwave datasheet, so this should be before any compression, frame size, etc shenanigans. So I think this is apples to apples DW 56Mhz/2048 = 995 Aviat 60Mhz/2048 = 1012 DW 80Mhz/2048 = 1245 Aviat 80Mhz/2048 = 1370 Peter Kranz

Re: [AFMUG] Higher power 18Ghz radios..

We need to know what they are basing this throughput on compression, frame size, etc. no way they can claim a 64 MHz bw (reference the emission designator in the chart) has the same throughput as a true 80 MHz bw radio at the same modulation. Sent from my iPad > On Feb 26, 2019, at 6:26 PM, P

Re: [AFMUG] Higher power 18Ghz radios..

Like we’ve seen with all vendors, what are these data rates based on? Aviat’s “AirRate” is the absolute rock bottom including the worst possible FEC, no compression, etc. When comparing apples to apples, the bit rates for similar bandwidths and modulations will be similar. Sent from my iPad

Re: [AFMUG] Higher power 18Ghz radios..

I also believe the Dragonwave Radio is actually a full 80Mhz channel based on the throughput.. For instance, the Bridgewave/Remec Navigator 80Mhz/2048QAM radio is 1248 Mbps vs 1252 Mbps from the Dragonwave vs 1370 for the Aviat.. Peter Kranz www.UnwiredLtd.com

Re: [AFMUG] Higher power 18Ghz radios..

If you’re referring to AF11, isn’t that an OFDM platform? Which is an unusual choice for a licensed radio, most are single carrier QAM. OFDM lets you implement with a DSP approach and naturally gives you a power spectral density plot that looks like “Bart’s head”. It naturally yields a certai

Re: [AFMUG] Higher power 18Ghz radios..

Modulations above 256QAM have diminishing returns, especially if you can’t do a true 80 MHz channel. Going from 2048 to 4096 QAM sounds like a huge leap, but it’s really 12 bits instead of 11. Also important to look at performance during rain fade, like what is xmt power at 256QAM, also how

@Tim.. WTM platform may not support 80Mhz channel in 18Ghz, you may be stuck with 50 Mhz according to the technical datasheet: So, reviewing… The delta between 64Mhz and 80Mhz is not that high.. ~118 Mbps or around 9% which is interesting given the 25% more theoretical BW. Aviat

Re: [AFMUG] Higher power 18Ghz radios..

If that’s the case, it must’ve been truly horrid at 56 MHz. There are consequences in this wasting of spectrum - you’ll notice that modulations less than 16 QAM are not currently coordinated or licensed since they fail to meet the FCC’s minimum of 1 bit/Hz. Any operation of the AF-11 at QPSK o

Re: [AFMUG] Higher power 18Ghz radios..

Yeah, but my point is that they made a really noisy 56mhz radio work by just occupying a full 80mhz channel... at least that's the way I understand it. It seems like they're kind of doing the same thing here. On Tue, Feb 26, 2019 at 3:24 PM Tim Hardy wrote: > While the AF-11 used a 56 MHz chipse

Re: [AFMUG] Higher power 18Ghz radios..

While the AF-11 used a 56 MHz chipset, the radio occupies 79.6 MHz - unlike all other radios with these chips that limit their bw to 56 MHz (this used to be the ETSI maximum). The AF-11 system gain is horrible for 1024 QAM when compared to other outdoor radios - either full 60 MHz or full 80 MH

Re: [AFMUG] Higher power 18Ghz radios..

Interesting, so I'm guessing that they're able to reduce the noise to an acceptable level at that high of power by using a narrower channel... kind of like what Ubiquiti did with the AirFiber 11. On Tue, Feb 26, 2019 at 1:54 PM Tim Hardy wrote: > > Just an FYI.. > According to this chart, the oc

Re: [AFMUG] Higher power 18Ghz radios..

Just an FYI.. According to this chart, the occupied bandwidth is only 64.5 MHz so you will be losing capacity vs radios that occupy the full 80 MHz bandwidth. The DW radio will have to be coordinated and licensed in one of the 80 MHz channel allocations as there are no FCC channel plans betwee
