Let me try this again... Apparently it didn't go through yesterday. -----Original Message----- From: John Seaman Sent: Wednesday, June 27, 2007 10:40 AM To: WISPA General List Subject: RE: [WISPA] TrangoLINK Giga vs Dragonwave
I wanted to set the record straight on few points here... Points 1-5: It is true the that TrangoLINK-Giga utilizes 56 MHz of spectrum to achieve throughput of 300+ Mbps. 56 MHz happens to be an ETSI (European) approved channel size. In the US, users can obtain (contrary to Charles claim) single 80 MHz liceneses at the same price as 40 MHz license. Charles' claim that you need to pay for two separate licenses is not true. The TrangoLINK-Giga system provides 311+ Mbps full duplex IP connectivity with one license. 6. TrangoLINK-Giga uses 256 QAM modulation to get 311+ Mbps FD (not 240 Mbps as Charles claims) using an 80 MHz channel. Using 128QAM TrangoLINK-Giga achieves 273 Mbps with a receive sensitivity of -64. (comparable to Charles' claim about Horizon) Now, to REALLY compare apples to apples, take Horizon's (per Dragonwave's datasheet) 40 Mhz channel 256 QAM (297 Mbps with RX sens of -60.5) and compare it to Trango 40 MHz channel 256 QAM (240 Mbps with RX sens of -63.2). It is not as different as he implies. 7. Again.. Charles statement is misleading.. He is comparing the output power of the basic Horizon to the Horizon high power version and noting a 7 dB difference between them. As per the Trango datasheet, the output power of the TrangoLINK-Giga (which depends on the modulation scheme) ranges from +17 dBm to + 20 dBm.. which is comparable to the high power version of Horizon for the higher modulation modes... And considerably higher than the Horizon base model. TrangoLINK-Giga has very comparable system gain figures with the Horizon high power version (which I assume costs more). Yes, the Horizon (High Power Version) power is higher for the slower modulation modes. 8-11. TrangoLINK-Giga is indeed a new product and Trango has in place a dedicated, experienced, hard working team working dilligently to ensure a smooth launch of this exciting new product. We are keenly aware that the initial success of this product will largely depend on the trouble-free deployments and operation for all of our eager early adopters. If anyone would like more info or clarification please do not hesitate to contact me. Please note that my posting is not intended to discredit Dragonwave.

There are two relevent prices to consider.... >Entry Cost and Full Speed Cost. Sure, let's compare apples to apples, to start: OVERALL THROUGHPUT 1. The TrangoLINK Giga requires 56 MHz of spectrum to get 311 Mb of FD throughput...the FCC doesn't allow someone to license a 56 MHz channel, so to run at this date rate, you would have to license 2 adjacent channels (2x the license cost, and at ~ $3500 / link, it's nothing to sneeze at) 2. From an entry point perspective, if you only license 1 channel to start (e.g., aren't using the data throughput), there's no way to "reserve" that adjacent channel...you have to hope / pray that in the time period that you "scale" that no one licenses your neighboring channel 3. Under Part 101, it is technically illegal to just "squat" on the frequency by grabbing that extra channel...you have to use it or you lose it 4. That said, if we're only going to use a single channel, the "Full Speed" upgrade point of the TrangoLINK Giga is 240 Mb FD, NOT 300 Mb 5. From a comparison perspective, Horizon has a max capacity of 350 Mbps FD on a single FCC channel (so it's 350 vs 240) RF PERFORMANCE 6. From a raw performance perspective, TrangoLINK Giga requires 256 QAM modulation to get 240 Mb FD...Horizon does 270 Mb FD with 128 QAM; the difference in receive sensitivity between 128 QAM to 256 QAM can be anywhere from 5-10 dB 7. High Power -- not sure about the specs of the TrangoLINK Giga, but having a High Power variant gives Horizon an extra 7 dB worth of output power...depending on the frequency, that can be almost 2' worth of antenna RELIABILITY 8. Like it or not, the probability of issues in a first revision of any hardware manufacturer's product is extremely high...Dragonwave has been producing licensed point-to-point radios for over 5 years and is on the 3rd generation of its hardware platform... 9. Trango's past 2 first "revisions" of hardware almost inevitably fails...look at their last several "new" products (I'm talking reengineered...HD Mesh is just Atlas + Mikrotik + glue, 2.4 GHz was based upon 900)...Atlas, 900 MHz...to me, it seems like it usually takes them about 1 year to get something to work properly...maybe 3rd time is the charm? That said...it's one thing to be "first" when it's only $1-2k, but $10k+ makes it a bit more painful when you've got to wait 6+ months for them to get it to work right ROADMAP 10. Dragonwave is a company that is focused exclusively and is committed to backhaul; it also has a product roadmaps for AirPair that allow for future upgradability (AirPair has a roadmap that will get it to 1 GB+ in the future) 11. Trango builds a product and a market, and then "moves on" Some food for thought -Charles Operating Manager CTI <- WISPA Paid Vendor Member & Dragonwave Distributor ------------------------------------------- WiNOG Wireless Roadshows Coming to a City Near You http://www.winog.com -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tom DeReggi Sent: Saturday, June 23, 2007 7:54 PM To: WISPA General List Subject: Re: [WISPA] TrangoLINK Giga Trango appears to have a MUCH better price point, considering upgraded to full speed. Although, I'm having difficulty getting confirmation on Dragonwave's Full capacity Best price, to be certain. Its also important to understand that there is a undisputed reliabilty advantage of having a combo indoor/outdoor model, regardless of whether an Outdoor model is mroe convenient and preferred by many WISPs. I guess I'm saying We should be comparing apples to apples, Airpair to TrangoGigalink, and not fair to compare Trango to Horizon prices because of that..

I thought it would be more aggressive from the newest player on the block. For the 100Mbps full-duplex version, it was only about 25% less than a similar Dragonwave setup. I guess I was hoping for more like 50% less. :) Travis Microserv Matt Liotta wrote: Our Trango rep provided us with a price quote. I didn't speak to the person directly, so I don't know if I am allowed to share or if it was based on a volume commitment. I will say it is in line with what most people are expecting out of Trango price wise. -Matt Tom DeReggi wrote: Charles, That statement, really depends on the price that is relased, and the volume the buyer is considering, as well as their time frame. If someone is planning on dropping 1/4-1/2 million on Licensed gear in a year, and the price is really good, allowing the provider to get 30% more links up for the same dollar, its not much of a risk being the first, considering the future potential reward. If the WISP's timeline is also spread out over the year, they have plenty of time to wait for bug fixes, before the bulk of the deployments. The golden question right now is, what price is Trango going to be at? The prospective buyers are predicting a low cost entry point, just because Trango has Always delivered industry leading price point, to jump start volume adoption in the industry. However, prior to seeing the price released, I'll say Dragon wave has the upper hand, for potentially being able to be the price leader based on their all outdoor design, compared to Trango's half and half indoor/outdoor. I will tell you, the most exciting news of the year for me, is clearly Trango's entry into the Licensed space. I selected them once for their Superior designs, and wouldn't hesitate to do it again, if they follow their own suit with the initial mentality of innovated products, such as the 5830 product line in it's day. With that said... I spoke with Dragon Wave, at the IWPC workshop this week. These guys get it, and is going to be a tough act to follow. The Dragon wave vision is to have a single management platform and infrastructure design for all your needs. Dragon wave is also very highly considering launching an E-band or 60Ghz product to their line, in the near future. Could you imagine that? Thats a product line that could bring WISPs to carrier class. Licensed Backhaul, GB near interference-free last mile.
