Re: [WISPA] Pathloss 4
Daniel, Most professionals use Pathloss. Most if not all commercial carriers use Pathloss I've been engineering Paths for 8 years and swear by it. Its worth it Knowing how to use it properly is priceless. I'm not in here much any more because some of the members like to go against the grain and try to re-invent the wheel with their profound knowledge and lack of experience. Pathloss is a winner. I've used it over the yrs to design networks in over 10 major US markets. 100-400 paths per market. Its a great product. You will need to know how to use a GPS. The software ( Pathlosss ) is a great tool but it should be used in coordination with a process of eyes on/ hands on . Nothing is more valuable than Driving the path and terrain to see what the software is showing you on paper. The software isn't going to show things like new construction. It isn't going to show you that 80' tree sitting on the highest terrain feature blocking your path with gear at 60' on the tower/rooftop.

Look at licensed. I know that is obvious but I think it is the only way short of bonding Orthogons together. I thought the max distance for 70 GHz gbps radios was about 7 miles. It has been a while since I read the specs. I am sure the rain fade would be an issue here. There is actually much less attenuation of 70 GHz than there is at 60 GHz. There is a spike of absorption of 60 GHz where water molecules eat that signal. It gets better above 60 GHz. I believe that you can go through the air better with as high as 100 GHz than what you can with 60 GHz. Obviously there are other licensed options in lower frequency space as well. I know Charles has some experience running licensed high capacity backhaul. Charles, what do you run for backhaul over 100 mbps FDX? Licensed doesn't make a lot of sense for us. We simply don't have the ability to predict where are growth is coming from. We routinely upgrade existing backhauls and/or reconnect our POPs together in different ways to increase our capacity and redundancy. With licensed we are forced to have a static configuration. I thought 24 GHz unlicensed had limited bandspace which made the top end about 100 mbps FDX? DragonWave seems to have a 24Ghz unlicensed product that can do 200Mbps full duplex. -Matt -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/ Check out the new AOL.

Re: [WISPA] high throughput backhaul options
Your point is extremely valuble considering there are alot of people out there claiming to use point to point radios when in reality they are putting up a Multipiont ap and sm with the spray and pray mantality. ( extremly unengineered and poorly erenginered.) Some of those same people don't have any kind of safty program. Yet they want to hire someone else to take all the risk not pay them and have the audasity to point the finger at someone else when they have issues. Usually done because as you stated they only care about me and could really care less about the industry the customers or average Joe that is just trying to connect two offices that are miles or blocks apart that doesn't even fit on the competion platform. There are alot of start ups that do this. I can't tell you how many I have worked with. Some are members of this digest. Its the same old game of I'm and expert after only a yr or so in the industry. While thats great for an upstart that doesn't really have any competition it is a grave industry down fall. Unengineered or poorly engineered links end up eating alot of man hours troubleshooting. The spray and pray mantality has no place in our industry its for amatures. -Original Message- From: [EMAIL PROTECTED] To: wireless@wispa.org Sent: Wed, 13 Dec 2006 11:17 AM Subject: Re: [WISPA] high throughput backhaul options Considering my name comes up here several times I guess I should reply Tom DeReggi wrote: So there is no misunderstanding. My original comment was based on radios like early WMUX, that used the whole spectrum range. I have nothing against high capacity radios 100mbps FDX and Higher. I don't have anything against selecting higher capacity radios when needed, or chosing a radio that is less efficient because it is the only radio capable to meet the need, or required to get the job done. Where my beef is, is using an unefficient radio to accomplish something when an efficient radio is available to deliver equivellent speed (at a reasonable cost). Price is not everything. As WISPs we have a responsibility to do the best job we can. We are not obligated to sacrifice, but we are obligated to live by example and do the best we can, with consideration of others in the environment. If someone is doing that, I have no beef, regardless of the technology that is used. Unfortunately you are not going to get the same latency with a half duplex radio. So latency is one issue. Another is security. Using something that is proprietary also makes your network more secure. So those are 2 good issues to coinsider why to not use something like a Trango for large scale backhaul. My post was not about wether PTP or PTMP or any specific radio or deployment design was more efficient than another, and irrelevent because there is a requirement for all types that have issues more important than the efficiency. My point was what ever method was chosen, the provider should be aware to install the most efficient system possible that does not have a significant trade off, within reason. But what do you consider a significant tradeoff??? I'd always recommend a 100mbps FX radio that used 32 mhz of spectrum over one that used 100Mhz of spectrum. That's fine as long as it meets your business model. But is the 100 Mhz. is more economical and I am not using that spectrum, then why not use it?? There are so many people that just put up links, and then say if I don't have problem with interference thats all that matters. That is selfish and foolish. What should they do?? Assume that they are causing interference and what??? Shut down??? I think the best you can do is design a system within your knowledge base and budget. Its not true that interference is bi-directional. I know that... The high gain system is going to kill the lower gain system. Usually. C/I is obviously important. The responsible thing to do is to do a channel scan/survey to see the free-est channel, and then broadcast on that channel, with the intent to avoid interference to others. But you know that's not a given... It is clear as day what is and isn't good etiquette, and those that do not follow it, will ultimately loose in my prediction. In my earlier days, if I felt interference, I just switched to another channel to avoid the conflict, an advantage Trango gave me easilly. Exalt does that in 1 Mhz. channels. And you can switch polarities via software also. But we don't do it anymore, we hold our ground. If our link is up, and we see new interference on it, we go after the interferer until they move. What does go after mean I can tell you, if someone puts up a radio using all 100mhz of spectrum, and it happens to cross one of our cellsite or subscribers taking them down, the offendor's link will be taken down (made unusable) within
Re: [WISPA] high throughput backhaul options
The right thing to do is to coordinate the install with the wisp so you can monitor the exsisting link while installing the new and have plan B ready to go if there is a conflict. No harm no foul. That can be a challenge if you don't know the wisp is even there. I have done this repeatedly with Government agencies trying to use unlicensed gear in an ever growing wisp markets. For you non believers a spectrum scan gives you great insite into what is out there. So you can plan ( engineer ) around it. If done properly, 360* on a verticle, horizontal, and diagnal polarity. You get great results. You may find complete spectrum saturation...you may find nothing..What ever you do don't do anything the right way and don't invest any money to do it right either. What do most do. Well I don't think I need to cover that, your point is well made. In south America several yrs ago it was called the AMP WARs which some members of this digest still do today. Thats the kind of unprofessionalism I am talking about. Thats also why it confuses me that so call professionals will use the cheapest spectrum hogs on the market and then brag about how big thier customer base is just to save a dollar and then bitch when they have issues with performance because they short cut and didn't bother with doing the home work. Youv'e gotta love Fluff. CHEAPER doesn't mean BETTER I don't care how well it suites your pocket book. If you can't afford to do it right then don't do it. If that means you need to hire someone to figure it out for you then hire them, but make damn sure you pay them if you want thier help in the future.

Re: [WISPA] Soapbox follow-on
Weather proofing is not just rain and snow ( weather ) but natural condensation
that happens with the natural rising sun. The Dew point.
Metals and sufaces become natural condensation pionts and as it collects it
will also evaporate and that will work its way into connectors over time.
Sometimes sooner, sometimes later. Having a protective barrier prevents that
from happening.
There is a specific way to weather wrap as well. You can't just courtesy, snot,
and wrap well you can but it wont last. you need to be specific in the way the
wrap is applied. Each layer is different. Just like a Roofer lays down
shingles. Some people will even use a clear coat spray or scothch guard finish
as one more layer of protection, from water and the baking sun light.
I have never had to use a coating spray but I know field techs that have and do.
My two cents,

Mike

Thanks for the kind words, Tom and Marlon. I knew there was a reason I liked
this List! {:-)
Tom, you've hit on a really good point, that system (installation)
specifications can be highly personalized, which is the central issue of
the current courtesy wrap debate. In my experience, properly applied mastic
and outer tape wraps yield many years of trouble-free connector service
life, with or without the c. wrap. (? Would that be crap from another
perspective?) {:-) And, by the way, a properly applied courtesy wrap is
stretched tight and overlapped so that it is, in fact, another moisture
barrier.
That said, I haven't noticed that this wrap, or its lack, affects
weatherproofing performance at all. What the wrap DOES affect is the ease
with which a connector can be taken apart for service. Not only is the stuff
fluid and really gummy-especially at summer temperatures-but it must be
remembered that it is inherently an INSULATOR. Any bits which remain on
connector threads during re-assembly can impede fully circumferential
shielding, and it ain't that easy to get all of the silly goop cleared off
fine threads. And anything that keeps my sorry old butt hanging up on a
tower longer than necessary ain't a plus either . So, it's really more a
matter of personal preference than absolute right or wrong; I merely prefer
specifying a wrap. Make sense?
As to your next topic, you are definitely preaching to the choir! Your point
that it's easy to make hasty and unfounded judgments is well taken-we've all
been there at some point-but this seems to me to occur far less often,
especially in smaller systems, than your first example. Many years ago I had

Ed,
Good post.
Without the courtesy wrap, mastic will flow into every possible space--like
connector threads--and become a real nuisance when a connection has to be
taken apart.
What is the harm of the Mastic flowing into every space like threads? Is it
really that big a nuisance? We haven't had that much trouble pulling off the
Mastic on our broadband connection, and the fact that the Mastic fills the
thread means a water path no longer exist, sorta like Plumbers using that
white thread tape. Would you agree, that if someone doesn't mind the
nuisance, not using the courtesy wrap, would be one level better
waterproofing? I'm NOT saying Courtesy Wrap is wrong, just that it may be an
installer's preference for convenience. Are you finding it to be more of a
nuisance, on different size cabling? For example Telcos tend to use much
larger Coax, and as a result have MUCH thicker rolls of waterproofing and
Mastic, which may be harder to cut through, and therefore more relevant to
have the courtesy WRAP?
I'm constantly amazed how many folks cannot seem to afford to do things
right the first time but seemingly can afford to do those same things over
another 2, 3 or more times.
I'll add that most often when things are not done adequately it is not a
decision of Affording. Its an issue of enforcement. The person
installing the gear is rarely the person responsible for the cost of the
repair after the fact, if one is needed. There fore people tend to be lazy,
and do the minimum to get the job done. I see it all the time. Installer
thinking, Oops, I left my Mastic in the VAN, so I'll use more Super 88
instead, or throw some plumbers putty in there,

Re: [WISPA] Lightning Protection
Your sapose to do both ground outside before you get to the shelter portand insideto tie into the ground ring inside the shelter. Your grounding should be every 75 to 100 feet of your cable run down the tower.So if you have 300 feet of cable run your going to have 3 grounds in your system TOP, MIDDLE, BOTTOM. I usually see at least two TOP and BOTTOM, one at the ODU and one inside or sometimes outside if the grounding bar/ring is on the outside of the tower.Nothing really wrong with just two, butone every 75-100 feetis standard. It can be different from tower to tower depending onhow the site was engineered and built. Example most ALtel sites have a ground bar at the port entery ( outside) to the shelter which ties into the main ground ring, on this site yes you would ground outside. You still have to ground the equipment to the rack inside the shelter, but your surge supressor would go outside. Other sites you will have to ground inside because the site designhas the bus bar ( ground bar ) inside just after the entery port. Both designs are very common. So to answer yes it does good to have a supressor inside its you last defence untill you get to the radio ( idu ) and then as long as its grounded to the rack and the rack is grounded to the ground ring inside the shelter it should be a well protected link but even then it isnt a garrenty that you are 100% safe. Lightning is a strange hazzarded to try to ward off. I am in Florida so I see just about everything as far as protect ion goes. And I can tell you right now that if your customer isnt a MAJOR carrier you site is probably not properly designed aganst lightning strikes so you need to bring them up to speed and properly ground the site or the customer is just asking for trouble.I work with a local WISP that had no Idea about grounding and I have had to redesign the ground rings on most of their sites. SO FYI it doesnt matter how much protection you put in if it isnt properlydesign inside and shelter and outyour equipment will get fried everytime.

I thought the suppressor was supposed to go straight to ground ?http://www.kywifi.com/images/vptower/CIMG5529.jpgCan someone clarify - I think we've been doing this wrong all of these years if this IS the proper way to do it .JohnnyO -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/ -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
