Brad,
I'm aware of your Atlas experience. We've gotten Full 45mbps out of an Atlas
numerous times.
However, I admit, often that does require antenna size upgrade, and that
needs to be factored into the end cost for comparison.
Add a little noise to the equation and that puppy will auto-rate
itself down to the 10Mbps neighborhood in a heartbeat.
Thats why you turn off auto-rate, and turn on ARQ.
I guess I just never get that excited about buying a radio that costs more
than a decent car. (when a car technically is much more expensive to make)

Not only that, but the Atlas isn't capable of 45Mbps in any form much less
FDX. Most we've ever seen out of an Atlas is maybe 20Mbps HDX with very
clean air. Add a little noise to the equation and that puppy will auto-rate
itself down to the 10Mbps neighborhood in a heartbeat.
Believe me these "up to" or "best effort" radios are tempting, but until you
deploy a few $15k - $30k PtP radio sets that actually produce what they
claim you won't understand what we're talking about.
When I say "you" I'm not directing that at anyone in particular just a
general comment.
Best,
Brad

Tom,
You're gonna bond 2 atlas links and get close to 100 Mb full
duplex????? How is that??
The 200 Mb Exalt is 100 Mb TX /100 Mb RX
If you use your equation you really need 4 Trango radios which is 5 x
$3000 = $15000 and that will give you 100 mb with 50/50 MIR. Not to say
what you would use up in spectrum (20 Mhz. x 5 = 100 Mhz......OK...you
could play with polarity with good antennas and probably do better).
So the Exalt doesn't look that expensive after all........ :-)
And BTW: I was told to expect MIR control for asymetrical bandwidth soon...

OK so lets compare to Trango Atlas or Alvarion Backhaul (which has
similar metrics) with equivellent speed models. Taking that maybe only
1% of my market could pull off a 64Mhz channel.
Exalt Specs... 200rating @ 64Mhz = 100 mbps then
100rating @ 32Mhz = 50 mbps... @ $16,000 list.
This of course being best case based on noise
level and acheivalbe modulation.
Trango Specs.... 54rating @ 20Mhz = 45 mbps, for $3000.
So, if I bonded two Atlas Links, I'd get equivelent performance to the
high performance version at 30% less spectrum use, and 1/5 th the cost.
Now of Course Trango, is Ethernet only, and does not have the wayside
T1 support or Fiber/GPS features. And there is value to that for
someone offering Voice services also.
All I'm saying is that the street price sure better be a lot lower
than the list price listed, as you suggeset it is. The second you are
in the > $15,000 range, you might as well be doing licensed for the
extra $1000 bucks or two to make it survivable.

Personally I couldn't be happier. They work as expected and stated.
They have relatively straight forward GUI interfaces, you can move
the center of the channel to any 1 Mhz. division, it works on 5.3,
you can get a straight indoor only unit or an outdoor unit with
integral antenna or N connectors, they have 2 year warranty. OOB
replacement guarantee, the inegral antenna has electronic polarity
control, it can syc all units on a msite so you can use one channel,
the gps option is very reasonable and you don't need a central
controller or cabling between radios. User defined latency and
channel bandwidth as well as free upgrade to 5.4 when it becomes
available.
The advertised throughput on a 200 Mhz radio is 100 Mb true
throughput in each direction port to port. The radio throughput is
based on a 64 Mhz channel.
Now lets address the Motorola Orthogon for a minute. It has no GPS
syncing. It has no integral fiber interface. The fiber "kit" is an
option that allows for cable runs in excess of POE lengths but you
still need external power. I can put a media converter and external
power on a Exalt radio also.
As far as the bandwidth is concerned the Orthogon still uses 60 MHz
to give full bandwidth. It just uses 30 on vertical and 30 on
horizontal.
On a positive note for Exalt the C/I is much better on the Exalt
radio which ultimately guarantees better distance in noisy environments.
The pricin on the Connectronics site is MSRP. You can get it quite a
bit lower...

Bob,
Tell us about your experiences with these. Work as advertised?
Approximate cost per pair?
Thanks,

www.exaltcom.com 100 Mb FD 2.4 Ghz. radio. Hmmmm..... I bet
Marlon would love to have one of these for a neighbor! :-) -B-
