Bob,
They way you wrote it, you are correct its not to bad at all.
My post was based on what I thought I read from someone else's post that
stated that the 200mbps model (raw) pushed 100mbps of throughput (real), I
was assuming based on waste of protocol overhead like Wifi. Trango has a
very efficient MAC with little waste. If the the Exalt does real throughput
of 100mbps in each direction, than that is a completely different animal and
value proposition. And getting 50mbps Full Duplex in 32Mhz, also might be a
speed leader in unlicensed.
Bob, have you confirmed actual real throughput?

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,

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