Re: [WISPA] Alvarion VL Fixes Problems with Backhaul Links
Travis, That is a very good point. And one of the reasons that I'm trying so hard to stick with Trango. Using something else other than Trango for me, is almost like cheating on my wife. But there is a slight difference in modifying each of the two. Modifing a Trango unit, also may infringe on patent rights with the manufacturer, or cause unrealised RF emmissions that would cause a radio to fail FCC tests. There are also risks involved in damaging the radio due to more detailed soldering, compromising things like field repairabilty. A StarOS system is likely a certifiable system, if it is decided to in the future to go through the beaurocracy of the certification process.

In some cases I don't have an option and just lose the prospect (as unservable). The industry is in a stagnet state, where manufacturers are not delivering an ideal product that WISPs need.

When I can keep the prospect, its often because I have cost justified installing a dedicated PTP for them. (I don;t have that option for every one based on lease fees for roof access and available spectrum). Trying to customize the FOX for external antenna is a major pain in the neck, not to mention illegal, or Non-FCC compliant. However, out of desperation, I have on occassion been able to successfully customize a FOX 5580, to use an ext connector, and paired it up with a MTI dual Pol antenna or Gabriel Dual Pol. The fun in this industry goes away, when the only way to get the job done, is to illegally hack a CPE, for jobs. Its not my job to be the manufacturer. The good news is that manufacturers are comming closer and closer to offering equivellent value propositions. The most promising products of Fall 2006, I feel is StarOS V3 on WAR, because of their low cost, and recent addition of true Bridging and Large MTU for adequate VLAN support. I also think, Alvarion has a winner with its new V4 firmware products, but I need to improve my finance options, to be able to use Alvarion network wide. What I'd rather have happen, is Trango fix the problem. It would only cost them a few thousand to fix the problem on their end, and will cost me a million to rebuild my network (which isn't going to happen). Thats the problem... What do you do when the product line you want fixed, is still the best choice in many cases overall ? There is no leverage to effect change.

The problem is that Trango kept degrading their gear more and more like Canopy. And Canopy kept improving their gear. Trango still wins, because Trango is less expensive. Canopy still has some of the traits that I also don't like about Trango (darn DSS dish antennas). My goal is to gain the High Arpu business. Who the winner will be is not a dying breed product, but the manufacturer that steps up to the plate to deliver a complete product. I want to be done with half-assed antennas. What I've learned is that the ANTENNA IS JUST AS IMPORTANT AS THE RADIO. Trango's strength had always been their internal antennas and options for good external ones. On a side note, Does Canopy 5.8G CPEs have external connectors? The truth is, I want the cheap CPE antenna option, for half my installs, cause it saves me money and thats all I need to do the job. I just don't want to give up the flexibilty to optimize reliabitly for the other 50%. The other thing you forget is, I'd now rather fight it out, and stay put on the channel, doesn't mean that I will win.

The reason is that if every time I hiot noise, I move away from the channel, eventually others take those channels., until they are all gone, and their is no where else to move to. Sometimes its better to claim the space and say, "I'm here first", "go find another channel to play on". And keep fighting back with better antennas. As the antenna grows, you over power the interference, but the important point is, you reduce the interference to you and them, by restricting the beamwidth. The high power via antenna you go, the more courtious it is to the other player to attempt avoidence of signals interfering. Alvarion gives that advantage.

Re: [WISPA] Alvarion VL Fixes Problems with Backhaul Links
Matt, Don't forget the laws of statistics. You also have been in business for less than 2 years. We didn't have interference problems our first 4 years either. It wasn't until year 5 and 6, that it started to become tough. I may have complained a little about trango today, but List please don't take it out of context. Every Telecom and their brother, is trying to install in our town, they abandon their effort in defeat, and I'm still here 6 years later. My market also has Fiber in 80% of the building, there is tough competition for the high ARPU business, and its a hard market to consistently deliver on. And its not just the radio, it every aspect of a company. We are evolving through the years of experience we have had, and when we select which links we install and don't install, we do it with responsible choices to protect our reputation as a company that can deliver high ARPU quality. I'd argue that our network is a last man standing network in our market today. A lot of my comments are based on that the market will be changing, and manufacturers need to change with the market to give us options to better offer quality broadband that can compete with Fiber. I'm not going to point to any specific manufacturer to say its not an adeqaute product for the WISP that chose it, I'm just saying that Canopy is no exception, none of the gear that is out there today is the perfect system, and they are all 5 years old technology. The company that has most currently risen above the others based on technology to meet WISPs current need has been Alvarion with their V4 product. Wether its enough value to justify the price, is for the WISP to decide, and whether it will stay that way is up for the competing manufacturers to decide. For example the only thing Trango needs to do to be the leader again, is to add a integrated 17-23db model fox or an EXT model Fox. They could easilly do that with little sweat. Or simply fix their ARQ firmware for the 5830 product line and not have to make any hardware changes. Whether they choose todo that, I have no control of. Maybe they are so excited about their next generation Wi-Max gear, they want to go straight to that? I don't know. .

Tom DeReggi RapidDSL & Wireless, Inc IntAirNet- Fixed Wireless Broadband - Original Message - From: "Patrick Leary" <[EMAIL PROTECTED]> To: "WISPA General List" Sent: Friday, September 22, 2006 3:09 PM Subject: RE: [WISPA] Alvarion VL Fixes Problems with Backhaul Links "My goal is to gain the High Arpu business." Tom, that is exactly where Alvarion excels and why it is my opinion that the more premium an operator becomes in the total quality of their service, the more likely an operator is to choose Alvarion. And these customers have different service level expectations that go far beyond the speed. They require a reliable connection that they can essentially forget about. Any connection that draws the attention of the end customer is a bad connection, because something is happening that forces them to deal with it. That is a distraction. That leads to a sense of insecurity, which is something a high ARPU customer will not tolerate over time. So Alvarion radios are built and given feature sets that allow an extreme level of customization (lots of depth in the VLAN abilities for example) and reliability (both physical and in terms of link stability). As well, as an operator you are able to pull a huge variety of statistics to reduce trouble shooting time when you do have to trouble shoot. And on the basic level, the way our radios use the air means we scan scale high ARPU customers better per sector than any other UL brand. That is especially true is you are offering more than just "high speed Internet access" such as VLANs and services like VoIP. It is plenty true that there have been numerous small WISPs that have left Alvarion (something I am going to work hard to change), but I have never met a SCALED operator that switch FROM Alvarion. I have met countless though that have moved to us as they have reached the stage where they need to become higher end providers. You are a prototypical example of such a WISP. John's is such a case. Marty's Roadstar is one of the most classic examples, having moved from 802.11b to Trango to Alvarion. Now for sure we are not perfect and we have our share of quirks, but we are out there still investing heavily (millions) in this unlicensed market, including on the product front. And we are fiscally very healthy and always have been. We are a horse a long term operator can tie his cart to. And I cannot understate how important that is. Many companies and all the huge telecom equipment providers (including Moto) are not investing in fixed now hardly at all, much less unlicensed fixed.

RE: [WISPA] Alvarion VL Fixes Problems with Backhaul Links
For sure we are a premium product, so we will never be near the lowest and don't ever want to be in that game. We try to offer value. That said, frankly, I personally am not a fan of how we list our pricing. MSRP is very misleading since each company may have a different channel model, or lack of one entirely. In other words, our pricing appears much higher than that which people actually pay, even people buying in quantities of one much less those buying in volume. In terms of oversubscription, having it or not is neither good or bad and there is nothing to tilt your nose to about oversubscription in and of itself. You offer a dedicated circuit and your clients pay accordingly much more and should. I assume they chose you because they want that dedicated circuit and believe you offer it at a value. Others chose to sell oversubscribed service, which is perfectly acceptable and does result in a lower ARPU than a dedicated circuit. That said, sure there are operators that WAY over subscribe. I've some cable ops doing 1000:1 residential which must be crappy service. We advise of a residential of 20:1 and a commercial of 4:1, maybe 5:1.

I have met countless though that have moved to us as they have reached the stage where they need to become higher end providers. You are a prototypical example of such a WISP. John's is such a case. Marty's Roadstar is one of the most classic examples, having moved from 802.11b to Trango to Alvarion. Now for sure we are not perfect and we have our share of quirks, but we are out there still investing heavily (millions) in this unlicensed market, including on the product front. And we are fiscally very healthy and always have been. We are a horse a long term operator can tie his cart to. And I cannot understate how important that is. Many companies and all the huge telecom equipment providers (including Moto) are not investing in fixed now hardly at all, much less unlicensed fixed.

For the golden answer. GPS only helps you design your own network, and I already take care to use best practices for my own network, when its comming from myself.

Re: [WISPA] Alvarion VL Fixes Problems with Backhaul Links
As much as I've protested Canopy, (in my mind poor design), the smaller the gaps are getting. The problem is that Trango kept degrading their gear more and more like Canopy. And Canopy kept improving their gear. Trango still wins, because Trango is less expensive. Canopy still has some of the traits that I also don't like about Trango (darn DSS dish antennas). My goal is to gain the High Arpu business. Who the winner will be is not a dying breed product, but the manufacturer that steps up to the plate to deliver a complete product. I want to be done with half-assed antennas. What I've learned is that the ANTENNA IS JUST AS IMPORTANT AS THE RADIO. Trango's strength had always been their internal antennas and options for good external ones. On a side note, Does Canopy 5.8G CPEs have external connectors? The truth is, I want the cheap CPE antenna option, for half my installs, cause it saves me money and thats all I need to do the job. I just don't want to give up the flexibilty to optimize reliabitly for the other 50%. The other thing you forget is, I'd now rather fight it out, and stay put on the channel, doesn't mean that I will win. With Trango, I still have the option to change my mind, when somebody beats me up, and I need to go run to another channel or polarity. Its always good to have a backup plan.

Yes that REALLY hurt the financials of my business. The reason, is that its a high noise environment where we're attempting to deploy, and its impossible to offer zero packet loss solutions with TDD unless ARQ is available, in these situations. It makes it worse with all the WiFi gear going up, because you don;t know its there half the time, until its starts transmiting. (darn I hate contention based). Yes, of course, Beta ARQ firmware exists for the 5830-ext, but it can't be used reliably. One of the big mistakes I made is I tried to use it, and learned that it locks up the SU radios every couple of days, when under heavy load. I did my testing of it on about 10 links. I started on 4 low use links, and it appeared to be stable, with only a random lockup every couple of weeks that I thought was something else. But after I installed it on the high volume links (other 6), they started locking up like crazy. (yes used most recent supposedly fixed firmware).

I'd rather not have the business, than to get my reputation tarnished by installing links the subscriber ends up cancelling and complaining about.

What you can't forget is that in PtMP, you can't encrease the antenna side of the AP. Not everything can be solved with the big antenna on SU side. Without ARQ one is toast. Trango gave me so much hope when they developed ARQ for the 5800 Foxes, which works fantastically. I'd select the Fox over a 5830-ext any day because of ARQ. But thats not good enough, I need ARQ and EXT connectors. Last year, I made Trango aware that we needed ARQ on 5830-EXT and Link-10s more than anything, and a year later, we still don't have it, and its not on their priority list. That is frustrating for my business. Customers don't wait in Urban Tier1 markets. When the Link doesn't go up in a few days, or their were a couple of noise issues that scare them, they have already placed their order with someone else. What it has forced me to do, is slowly start swapping out my Trango APs, to make room (spectrum and antenna lease fees) for radios that can deliver packetlossless links. Even Wifi gear can offer packetlossless links. And its forced me to go back and re-negotiate my contracts with property owners to try and not pay per antenna, so I can get more antennas of larger size (PtP) for less money on the roofs. Its a BIG waste of time, that I wouldn't have to do, if Trango added ARQ reliable ARQ to 5830-ext. I'm still a Big Trango fan, and still am basing my business around its product, because of its value proposition, but I am loosing sales and getting more black eyes than I have to, because Trango does not have a EXT antenna product line that delivers reliable ARQ. I haven't bought a new Trango 5830 AP in ages, I have to many pulls on the shelf waiting, when I need one. If Trango never released ARQ for the FOX, I would have never kown what I was missing. But now that I have experienced it, I can't live without it. The two biggest reasons, for lack of progress in my company is, 1) Waiting for technology, and 2) Waiting for finance to come through. I can't count how much money I burned just waiting. I don't want to wait any more. I'm tired of waiting. I don't have the energy to keep waiting. I want it now. I need it now. This is a time to market business, where there is a domino effect of disaster tied to waiting.

RE: [WISPA] Alvarion VL Fixes Problems with Backhaul Links
I fully believe these payload rates are achievable in little or no noise environments. I think it's important to add a disclaimer stating these rates are theoretically obtainable under ideal conditions. In comparison a product that has mechanisms to avoid noise or block noise will perform better. Our VL setup running v4.0 is only able to achieve 2-3Mbps uploads TCP HDX and 8-10Mbps downloads TCP HDX. Running TCP FDX tests is pretty ugly, so I won't even bother posting.

RE: [WISPA] Alvarion VL Fixes Problems with Backhaul Links
I fully believe these payload rates are achievable in little or no noise environments. I think it's important to add a disclaimer stating these rates are theoretically obtainable under ideal conditions. In comparison a product that has mechanisms to avoid noise or block noise will perform better. Our VL setup running v4.0 is only able to achieve 2-3Mbps uploads TCP HDX and 8-10Mbps downloads TCP HDX. Running TCP FDX tests is pretty ugly, so I won't even bother posting. This is a real world deployment under real world noisy conditions not a "glossy ad best case" claim by a manufacturer interested in pushing boxes off the shelves. Patrick, any chance Alvarion will reconsider a software switchable Dual Polarity AU and SU? Any chance Alvarion will consider offering both 5.3GHz and 5.8GHz bands in one product?

RE: [WISPA] Alvarion VL Fixes Problems with Backhaul Links
Agreed that Trango has clearly fallen behind...way behind. However, the VL is also far from being an "end all" solution. The VL has no mechanism to avoid interference (No RX threshold etc.) other than just to retransmit. Also, the VL does not offer the flexibility to change polarities on the fly. In fact Alvarion doesn't even offer an H Polarity SU INT and if you rotate the V Polarity SU to H you'll likely have a water penetration problem. The VL is only available in a 5.3GHz or 5.8GHz solution further limiting the flexibility the product offers. As our HUB sites increase in number and decrease in required coverage area we have found the 5.3GHz band to be VERY valuable. You do not have that flexibility with VL. When Alvarion is presented with the freq and polarity suggestions they simply respond with "we're RF purists" talking points. No indication that maybe, just maybe those would be good features to add to the product. We deployed a VL in an above average noisy environment with the latest v3.x firmware and the results were dismal to say the least. Fortunately upgrading to v4.0 allowed us to salvage the deal, but we still can only pass a few Mbps. This is far less than what a Trango M5830AP can do in a noisy environment. As with most things YMMV.

to see if it all works financially. Alvarion's numbers don't work everywhere, but after the fact, we are finding that they actually would have worked in more places than we originally thought. Now in fairness, I have made some cross comparison between PtMP and PTP products. The Trango Atlas has an external antenna option also if doing PTP.

OK, so we haven't found a way to use Alvarion equipment on residential markets except where we don't have to compete with $30/mo dsl. But I know some folks, even on this list, who somehow have done that. But on the business side, our transition from Alvarion BAII or 900 to VL has had the same response from our customers that you describe "wow, that is fast". Mind you, these customers are still limited on our bandwidth manager to the same 1Mbps symmetrical speeds. But the VL network just seems to fly compared to the previous, 4 or more year old technologies now. It's also hard to try out other technologies when someone like you give a report like this one: I was thinking about using Trango for a link, but I do not want headaches, not today and not 5 years from today. Thanks. Mario John Scrivner wrote: As you guys know my company was having some serious speed and reliability issues with our existing Trango backhaul some time back. We have about 25 tower locations in Southern Illinois which until recently were all fed from these Trango radios. We had countless short outages, signal irregularities, bandwidth crunches, etc. The Trangos used to work just fine. In the last year or so the Trango links have become a big problem for us. We tried several things to fix these problems but the Trangos were simply being pushed to do more than they were designed to do. The amount of packet counts, speed, etc. we needed to reliably serve the towers simply was too much for these radios and they were buckling under the strain. I have always thought highly of Alvarion and knew we could probably find a good place for their equipment in our network someday. Previously the trouble with choosing Alvarion had always been that we either needed something they did not offer at the time needed ( as was the case when we selected Trango for multi-point 5 GHz backhaul back in the day) or that they were too expensive. Alvarion finally has a place in our network. In the case of our troubled backhaul links Alvarion's VL product seemed to fit the bill to help us now. We had seen reports of 50,000 packet per second throughput and up to 35 megabit per second capacity with the new Version 4 of the VL firmware. When I asked about the product I was directed to a guy named Mike Cowan of Wireless Connections who is a RF engineer and sells Alvarion VL. Mike spent an incredible amount of time with our staff to look over the issues we were having and help us find ways of correcting it. He never charged us a dime for what I consider to be thousands of dollars worth of support and training. Mike Cowan and Alvarion did more for us to help us build a better WISP network than any vendor ever has since the day I became a WISP. We also had some serious peer to peer traffic issues on our network which were resolved with a Mikrotik box running to slow down that traffic. The combination of this box and the new more robust Alvarion VL backhaul has led customers to remark, "It's like the difference between night and day". We have zero downtime on our backhaul now. We were getting countless reports of downtime from our network monitoring system before. Now it just works. I don't think I can overstate the impact Alvarion VL has had on my network. If you are having problems with your network then you need to at least call Alvarion and give them a shot. In the last three months or so we have migrated about 40% of our backhaul links over to Alvarion VL. Since that time outages on those most troubled links have vanished. Throughput has tripled. People have gone from screaming and yelling to sending their friends to us to hookup. If you guys want to compare the numbers out there I am sure you will find a few different systems that will give comparable umbers to what we are seeing with Alvarion VL. What you do not see in those numbers is the quality and the reliability of the system. I have always been a tinkerer and I will continue to tinker. What I believe though is that there is something to be said for buying a high-quality, engineered system and that is what you get with Alvarion VL. If you have tower locations and/or enterprise customers who cannot afford to be a test subject for your tinkering then consider calling Alvarion for those links. There is no shame in admitting you cannot possibly build a system as reliable as a company who has spent millions of dollars and hired countless designers to research and build a better data radio. I am certainly not ashamed to
