As George said, the G2 definitely supports higher xmt power at lower 
modulations if set manually.  They actually promised me the auto feature, even 
gave me a due date and release number for the firmware.  I think what happened 
was they released the G2 with promo pricing, and discovered people would only 
buy it at the promo price, so they pulled development off it.  They also went 
through a messy ownership change around that time, who knows if they even have 
engineers anymore?  Although they released a 6 GHz version of the G2, so I 
guess there’s some development.  They have some big utility customers, like in 
the energy sector, maybe one of them wanted an inexpensive 6 GHz radio.

 

It’s not that big a deal, just annoying.  Wouldn’t be the first time a vendor 
promised something in future firmware and it didn’t happen.

 

It’s the last month of the year, you could always call around and see who needs 
another sale for their quarterly or annual sales numbers.  Nothing wrong with 
Trango Apex Plus for that application.

I think you may be asking too much to desire ATPC / varying transmit power 
levels on Exalt's lowest priced model 18 GHz licensed band link. 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.

I really hate to admit it, but those requirements would make me look at Exalt 
once more. 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.

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.

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.
