Re: [WISPA] In-Wall AP UniFi
Matthew, Working for a Wi-Fi manufacturer (other than Ubiquiti) I'd like to offer some advice based on what we see in the hospitality market. Creating sufficient density, capacity and coverage solely with the 2.4GHZ band is really hard to do. You might be able to pull it off if the hotel is very small, you use the lowest TX possible and put an AP in every guest room. Otherwise, I'd work toward creating a dual-band network and make the most of the 5GHz band. When we engineer hotel installations we often disable 2.4 on 'every-other' AP. This is not a hard and fast rule of course. Architecture, construction and materials will play into that decision, but in general, we turn down 2.4 to half-power and disable many of those radios on our dual-band APs. Most of our hotel installations are governed by the brand (or flag, we like to say) and as such, we are seeing a big push to in-room APs that support 802.11ac wave 2. If the UniFi In-Wall AP meets your needs, great. They do make a really fine product, but engineer carefully. Best of luck!

Re: [WISPA] Alvarion Tech support
Hey Cameron, The new firmware for the VL900 platform indeed provides better performance. The new filters are hardware based but controlled in software. One of the new features is the ACCS and NFS controls (Automatic Clear Channel Selection and Noise Floor Selection). The way this will work is the Spectrum Analyzer Mode will determine the noise characteristics per channel and then can make an automatic selection of noise floor and clean channel. There will still be manual adjustment of optimization rules for skilled users available in the interface. If you didn't catch the webinar last week, one of the tests we ran was a head-to-head comparison against another 900 MHz radio. We tested six locations that were all NLOS. We outperformed the other radio in five of the six locations and could connect in every location whereas the other guy only registered a connection in three of those sites. (50%) You all will be the first to know when the firmware is GA. We are taking orders for hardware through partners and distribution channels.

Re: [WISPA] 3.65ghz sector
Hi Gino, I am glad to be here. Thanks much. When you follow the link I sent earlier (I got it from www.wispa.org) you will get three items in return; a ROI white paper that covers most of your questions from below, a datasheet on the product line and a link to a video that a partner put together detailing a drive test. Very cool stuff. Check the link out and if you have unanswered questions please let me know. One more note. A few months back we put out an excellent guide on how to obtain the 3.65 license from the FCC. It was authored by a former Alvarion person who is no stranger to the list. (Gotta give credit where credit is due, we are still friends.)If anyone needs a hand on how to get authorized for the band, whether you are implementing our gear or the next guy's, this is the place to start. http://www.alvarion.com/3650licenseguidedownload/?ref=WISPA.orgsource_t ype=Text For both iterations of our 3.65 product line you do not need an ASN. DHCP for the CPE broadcast domain is definitely a good idea. We don't require DHCP to manage the network. As in any network an NMS is always a good idea. I have never met a doctor that does not carry a stethoscope. Network visibility, trending, alarming, software updates are all important tasks any operator faces. However, we do not require an NMS right out of the gate. You could migrate to our own NMS called Alvaristar as well as a configuration tool called Alvaricraft. Since we support SNMP you could use your own tools already in place as well. I hope this helps folks.

Re: [WISPA] Tower accident
When I was on your side of the business (working for an integrator), I took the two-day ComTrain course. I usually worked the ground, prepared loads and worked the winch or tag lines. I was not interested (nor my wife) in working at height. But the course taught me valuable lessons; first, I learned what it took to be safe. It enabled me to watch over the guys about to go up the structure, check their gear and make sure they had the gear that was needed to be safe. But second and most importantly I learned how to do a rescue. Thankfully I never needed this skill. Most fire departments as I learned from ComTrain do not have a clue what it takes to get a man down off of the steel. Time is precious in those situations. Glad I knew how, glad I never had to. So I am curious. For those of you that only need to send one climber to complete a task, how many of you send two climbers so that there is always someone certified in rescue on the ground? And if so, are the equally equipped? This is a great topic spurned from a tragic and preventable accident. One more note. I hired a crew to do an emergency repair on a Crown tower we co-located on, in February many years ago. It was REALLY cold. So they sent a two man crew to replace two Alvarion ODUs. They both climbed and did not leave a guy on the ground. The first guy was properly clothed and took his time getting to 325'. The second guy did not like the cold and decided to climb the second leg and race up to the radios. I doubt he was 100% or he would not have been able to move that fast. In the end he exerted himself so much that he sweat on the way up and as soon as he reached 325', he could not feel his hands or feet. I pulled him off the tower and told his foreman to never send him on one of my jobs ever again. At least he left the site under his own power that day.

Re: [WISPA] Cat5/PoE grounding on tower
Mark, You did not mention what system you are using or cable type. However, if the CAT5 has a braided shield or a drain wire you can use a kit from Andrew that would be applied much in the same fashion as a coax ground kit. Depending on the length of your runs you may wish to ground the middle of the run as well.

[WISPA] Multiple DNS implementations vulnerable to cache poisoning
Thought the community should be aware of this one. A rather lengthy blog detailing the exact mechanics of DNS cache poisoning got leaked yesterday. -Eric http://www.informationweek.com/news/internet/security/showArticle.jhtml? articleID=209401195 http://www.kb.cert.org/vuls/id/800113 The Domain Name System (DNS) is responsible for translating host names to IP addresses (and vice versa) and is critical for the normal operation of internet-connected systems. DNS cache poisoning (sometimes referred to as cache pollution) is an attack technique that allows an attacker to introduce forged DNS information into the cache of a caching nameserver. DNS cache poisoning is not a new concept; in fact, there are published articles that describe a number of inherent deficiencies in the DNS protocol and defects in common DNS implementations that facilitate DNS cache poisoning. The following are examples of these deficiencies and defects: Eric Albert Application Engineer Alvarion, Inc.

RE: [WISPA] Which UPS to use?
This seems like a good opportunity to lob in a sales pitch of sorts. But I will disguise it as an engineering discussion to appease the tech crowd. I will preface my comments by saying I do not know the original application for which this question was posed. Most of the gear (there are exceptions) in our business, in the end run on DC power. Our radios are a good example. The chassis based BS-AU can run on -48 VDC power supplies and supply the necessary DC voltages to the cards and ODUs. The process of running a UPS (which in application is a battery powering an inverter) only to knock down the 120VAC into DC seems overkill. The process is inefficient, generates heat and can be expensive. This process is commonly known as the double-conversion method. Side bar: some UPS units, not all, don't handle power correction. They will kick on during under/over voltage situations but they do little to correct for the quality of the power. Over time poor AC power quality will chip away at the MTBF of everything connected to it. I have also heard that many of the more popular UPS units have trouble with generators, especially the generators that have automatic throttles. If the quality of the generated power is poor it will burn up the MOVs that are in place at the input side of the UPS. But I digress... I think the Telcos have had it right for some time. Although how they got there is another discussion. But in the end DC power affords you some options. A properly engineered DC power plant will take the brunt of bad power and isolate it from your gear. The rectifiers take the hit so to speak and the batteries don't care. Any power events such as brownouts, surges or blackouts don't get telegraphed to the radio equipment. Another point worth noting is the availability of modular-based rectifiers and battery chargers. Lots of options. (I have even seen hydrogen fuel cell units in place a major POPs. Really cool gear.) One WISP who has employed this design had a long outage that almost drained the batteries. They pulled a pickup truck with a full tank of gas up to the site and topped off the DC string. Others have taken the approach of using wind/solar/hydro/utility. Also, if you can build a POP on nothing but DC, think of how much energy you will save just by cutting out the wasted heat that an inverter (or UPS) creates. If the design calls for a cabinet, chances are you will not back-up the air conditioner. Where does all that heat go during a long outage? (DC fans anyone?) Here is the sales pitch. Alvarion manufactures several options in the DC genre. We have the aforementioned -48VDC PS for the BS-SH chassis solution. When you design a system with one radio family (i.e. VL) redundant power supplies can be implemented at the tower. And now, for the Pièce de résistance, we have a DC standalone power supply for VL. It is the OPS-DC. Its input range is 10.5 to 32 VDC and draws less than 1A at 24VDC. Slightly more draw at 12VDC. The temperature range is -31 to +131F. Why all the hoopla? A DC battery charger with a good deep cycle battery and the OPS-DC could run a VL sector for... well, a really long time. This idea will certainly not work for everyone or for every design. But it sure is fun to imagine the possibilities. I hope to hear some creative responses. Thanks for reading.

RE: [WISPA] LMR600, LMR900, Heliax
Dear list, I have not seen anyone comment on the principle of coax cutoff frequency and how it can impact the decision to use one size of cable over another. Some of our customers have run into this problem. The problem of not being able to install the tower electronics right next to the intentional radiator. It is not our preferred installation method but it does happen. The Cutoff Frequency of the coax is an equally important consideration in addition to loss and physical characteristics. The outer diameter of a coax cable is (roughly) inversely proportional to the cutoff frequency. If the physical 1/2 wavelength of the carrier is SMALLER than the diameter of the coax then problems will ensue. When the size of the coax is large enough that more than one RF path exists, the frequency is above cutoff frequency, and cable attenuation is very high, and return loss is very high. If multiple modes with different phase velocities propagate within a span of coax, interference can occur within the medium itself. In RF cable, the best operation occurs when only one path for the RF exists.

Static protection, grounding, electronics all swap out as a unit. For locations that are hard to climb, I use radio at bottom, amp and antenna at top. Started out using HyperLink amps, now use RF Linx. Over 7 years, I've had 2 amps fail, and 1 antenna and amp destroyed by a direct strike. In the direct strike, the amp saved the coax down the tower and all the radio gear below... And RF Linx replaced the amp under warranty.

Look at any cell tower and you will see what you need to use, then count on twice the loss if you use 2.4 or many more times that at 5.2 or 5.8 Look at a price range of tens of $ a foot, once installed properly. This brings you to the next obvious issue. Now for the lesson in RADIO. You have degraded your system so much by adding loss, you can figure that your antenna just magically became 0 dB gain instead of what it was. You may even totally offset the antenna gain and be upside down (as they say at the car dealer down the street). So go buy the best antenna you can, with the most gain possible. Of course now that moves us to the next step. Can't get a high gain antenna

Hi Brad, The cable we supply with the VL product is terminated following the ANSI/EIA/TIA 568-B2 standard. We pre-terminate the cable in an effort to speed the installation process. The design of the weatherproof boot is intentional to provide an impervious seal from the elements. Having installed more of these radios than I can count in previous roles, I admit learning another color code can be daunting. But it is only eight conductors. When done properly it tests the same as any other straight cable. Happy Holidays!

So what's the impact overall to you business model under the AlvarionCOMNET program?

We have deployed a LOT of these radios already and I can tell you this is a great price. I'm looking forward to Alvarion extending this program to other products. (Patrick...)
