You just voted to put a self promoting business man to the highest office of

and  you are literally 'harping' on another business who is self promoting 
their product....

 

What gives .....

 

Maybe UBNT should be saying... "The AF11x is the best radio, As a matter of 
fact they only make the greatest Radios, and only they know how to make those 
radios.. Those are all phenomenal products,  very successful " ... Let's all  
"Make Broadband Great Again"

 

Would that help you in getting off their case ?

Sure, but don't claim you're better when you're not. There's nothing wrong with 
building a reasonable product for a great price if that's all you claim to be.

Real usable capacity at Layer 2 Ethernet depends on several variables besides 
the modulation level and the regulatory bandwidth.  For 1024 QAM there are 10 
bits per symbol so theoretically one would expect to get 400 Mbps in a 40 MHz 
channel (10 bits x 40 MHz symbol rate).

 

To actually make a radio that meets FCC spectrum masks, a reduction of the 
symbol rate down to around 35 MHz is required plus filtering, giving a max of 
350 Mbps over the air. 

 

After that, Forward Error Correction (FEC) is required which is typically 
around 85-90 % for most microwave radios using LDPC, giving a net throughput of 
around 300 to 315 Mbps.  

 

Add header compression at layer 2 which in the worst case for large packets 
adds about 2.5 % improvement and you get to around 325 Mbps, which is what 
Trango and others get on a single 40 MHz channel with the newest technology.

 

Ubiquiti maybe using a lower FEC rate like 75-80% (or a lower symbol rate if 
the filtering is not steep enough) and no header compression, which would give 
them about 250 Mbps for large packets.

 

Hope that helps!

What other radios will only do 250Mbps (502.4Mbps capacity according to the 
data sheet...) on one 40mhz single polarity channel at 256qam? The other's I've 
looked at are typically around 300Mbps...

Not that I'm saying the AF11 is a bad radio, I plan on putting up at least a 
few of them this year... but I find it a little funny that they use 1024qam as 
a selling point, when it can't do as much throughput at 1024qam as other radios 
do at 256qam.

I think this whole thread can be summed up that there's no magical way to get

divorced from reality, it's not 1200 Mbps no matter how many slick PDFs they 
publish.

One 40 MHz channel single polarity at 1024QAM 5/6 code rate is going to be 
nearly the same efficiency bps/Hz from many different manufacturers. Multiply 
as necessary for dual polarity or for larger channel sizes such as 60, 80 or 
112 MHz.

But if I can get 80mhz channels in both polarities (running at 56Mhz/1024QAM 
with this radio), I should be able to at least double he capacity of my PTP-800 
link which can do 228Mbps.  Right?

At 40 MHz and a single polarity, you're looking at an almost insignificant 
increase in throughput.

Their claim is 1.2 gb+.
Cut that in half as they're advertising the aggregate, so 600 mb+.
That's using both polarities, so now only 300 mb+.
Only I haven't heard of anyone getting much more than 500 in a single direction 
(they may certainly exist, I just haven't seen them), so now that 300 is really 
only 250.


Not much of an upgrade unless you can also get larger channels in both 
polarities.
