Re: [WISPA] Re: Anyone using Exalt radios????
In order for us to keep ahead of the LECs and cable companies we need better products not cheaper ones. Well said, but can't we have our cake and eat it to? How about Better radios, Cheaper :-) High priced vendors don;t have high prices because their costs are higher. They have higher prices because they feel the market will pay higher prices based on the benefit of the product. When it becomes beautiful for buyers is when their is enough competition and varietty of high quality gear, that it starts getting sold based on the cost to produce instead.

Achieving advertised payloads 24x7 and not up to or best effort regardless of the environment (for the most part) is where the line is drawn. Good example is a TeraBridge 5x45 PtP radio set that costs between $8k - $15k depending on antennas, volume pricing etc. This is a radio that produces 45Mbps FDX period. No auto-rating, no ARQ, no ifs, no ands or buts. That's 90Mbps aggregate using only two 16Mhz wide channels. This radio was originally designed and built probably long before Trango even existed and has changed brand names no less than four times during its life. As the saying goes; They just don't make 'em like that anymore! lol Of course that doesn't mean the radio is immune to interference, but as long as you have enough gain over and above the noise floor they produce 45Mbps FDX. We have several pairs running in arguably one of the noisiest environments in the nation. In two separate cases we tried the Atlas at either side of a TeraBridge and the Atlas just couldn't cut the mustard. The Atlas is truly a toy in comparison to the TeraBridge. Back to the point of this thread...the Exalt radios look promising. I hope we see more products like the TeraBridge and Exalt radios. In order for us to keep ahead of the LECs and cable companies we need better products not cheaper ones.

But I get what I get where I get it. What I've been finding is that similar expereince is received with other products.(Meaning they don't always get their speed either). Most of my Atlas Links (above 10 miles) are not running at top modulation, they usually operating optimally (no packet loss and low latency) at the 36mbps modulation level, which pushes real data of significantly less, I forget the exact speeds with IPerf, but it was real close to 30 mbps. I don't have a single Atlas running slower than that in service. But on shorter links, we've gotten full modulation and full speed (45mbps) out of the Atlas. I believe I did post some speed results on the list over the summer. But you are right you can't get it in a very noisy environment, if you have to get the TX and RX power to high. But its not really a distance limit, its a delicate balancing act to get everything just right. (RX signal not to high, TX power not to high, RSSI 20db above noise floor ). Its all controlled by using the right antenna. The Atlas also makes a GREAT 5.3-54 backhaul, for links under 5-7 miles. When it operates at the low power, it runs much cleaner. PS. recognize that my first post, I did not catch that the Exalts were FDX.

RE: [WISPA] Re: Anyone using Exalt radios????
So is it safe to say that one could get one of those $9k Dragon Wave links licensed and ready to go for $12.5 - $15k? It really depends on dish size and licensing situation For example, licensing for a government entity (county, school, etc) is on a different schedule (costs about $1k) vs. licensing for a common carrier (WISP, Telco, etc) Also, w/ multiple links, things can change It gets complicated, but I can explain further if you want -Charles --- WiNOG Wireless Roadshows Coming to a City Near You http://www.winog.com -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/

Re: [WISPA] Re: Anyone using Exalt radios????
Brad, I recognize your points and don't deny them. But I get what I get where I get it. What I've been finding is that similar expereince is received with other products.(Meaning they don't always get their speed either). Most of my Atlas Links (above 10 miles) are not running at top modulation, they usually operating optimally (no packet loss and low latency) at the 36mbps modulation level, which pushes real data of significantly less, I forget the exact speeds with IPerf, but it was real close to 30 mbps. I don't have a single Atlas running slower than that in service. But on shorter links, we've gotten full modulation and full speed (45mbps) out of the Atlas. I believe I did post some speed results on the list over the summer. But you are right you can't get it in a very noisy environment, if you have to get the TX and RX power to high. But its not really a distance limit, its a delicate balancing act to get everything just right. (RX signal not to high, TX power not to high, RSSI 20db above noise floor ). Its all controlled by using the right antenna. The Atlas also makes a GREAT 5.3-54 backhaul, for links under 5-7 miles. When it operates at the low power, it runs much cleaner. PS. recognize that my first post, I did not catch that the Exalts were FDX.

RE: [WISPA] Re: Anyone using Exalt radios????
Hello Tom, Well, that's the point we're trying to make here as to why not all radios are equal. Achieving advertised payloads 24x7 and not up to or best effort regardless of the environment (for the most part) is where the line is drawn. Good example is a TeraBridge 5x45 PtP radio set that costs between $8k - $15k depending on antennas, volume pricing etc. This is a radio that produces 45Mbps FDX period. No auto-rating, no ARQ, no ifs, no ands or buts. That's 90Mbps aggregate using only two 16Mhz wide channels. This radio was originally designed and built probably long before Trango even existed and has changed brand names no less than four times during its life. As the saying goes; They just don't make 'em like that anymore! lol Of course that doesn't mean the radio is immune to interference, but as long as you have enough gain over and above the noise floor they produce 45Mbps FDX. We have several pairs running in arguably one of the noisiest environments in the nation. In two separate cases we tried the Atlas at either side of a TeraBridge and the Atlas just couldn't cut the mustard. The Atlas is truly a toy in comparison to the TeraBridge. Back to the point of this thread...the Exalt radios look promising. I hope we see more products like the TeraBridge and Exalt radios. In order for us to keep ahead of the LECs and cable companies we need better products not cheaper ones.

Re: [WISPA] Re: Anyone using Exalt radios????
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. 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.

Re: [WISPA] Re: Anyone using Exalt radios????
Never heard of them before until now...just talked to a sales rep and got unnoficially ~$12k. It looks like software defined radio so they probably have the capability to develop firmware to do a lot of the things that Orthogon did. He said they don't currently have a spectrum management feature or a 'lite' product like orthogon but likely will be incorporating something into upcoming software releases. For error correction they use variable mod. and FEC, software polarization selection, a few other things. Either way a product to keep an eye on... Jon Langeler Michwave Tech. Gino A.

Re: [WISPA] Re: Anyone using Exalt radios????
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... -B- Tom DeReggi wrote: The advertised throughput on a 200 Mhz radio is 100 Mb true throughput in each direction port to port.

RE: [WISPA] Re: Anyone using Exalt radios????
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.

Re: [WISPA] Re: Anyone using Exalt radios????
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.
