we have 3 foot links over 20 miles and they work great, florida rainy here, when rain fade occurs you have adaptive modulation and rapid port shutdown that works well.

Re: [WISPA] Licensed Backhaul
Cost effective depends on your goals. Its nice to see products comming out like APEX9, enabling $6900/link pricing standard, which are fully feauture rich to latest standards. 366mbps is a lot of bandwdith for most people. And companies like Solectek offering discounts on their older generation model, that are still good upto 300mb, and had amazing even lower pricing.(note they also have new generatin products) Those are all great examples of more "cost effective". However, I'd like to point out Trango BRoadband's latest models that support Compression and that they are awesome. The compression really works at less than 1ms, and I've seen anywhere from 1.5 to 4X capacity increase compressed, allthough spec sheets tend to advertise 2x to be conservative. Its obviously more cost effective to buy 1 radio with Compression, than 2 radios without to get the same speed, if need more capacity than 1 radio can provide, or if you cant find another free channel or large channel. What do you do if you wanted a 50mhz channel, but you only found a 30mhz one available in your freq coordination? The answer is use a radio with compression. Whats most cost effective, is getting the best $ per mb, not necessarilly best $ per link, and knowing that each MB is a resource that can be resold for a higher reoccurring profit. More bandwdith equals more potential profit. You need to consider your site requirements, and labor involved. Its more cost effective, to put up an all-outdoor CAT5 Licensed radio unit, if replacing a pre-existing all-outdoor CAT5 5.8G link, being able to re-use preexisting cabling. Or if you are paying for colo space per months, its more cost effective to use a little POE indoors mounted to a wall, instead of a rack. You could easilly assess a $2000 cost savings on install labor and supplies selecting an all-outdoor unit instead of Split archetecture. In the long run, you might find a split archetecture to be more cost effective, considering you only have to stock one model of Indoor Unit for all freqs and all sides of links, if the IDU was designed as a multi-band type. If you bought one brand of radio for every link, you might see a cost savings in NOC support labor and development, as software OS and training became standardized network wide. I can tell you the first step is to define the need. Second step is defining what product will be most costeffect to solve that need.

Re: [WISPA] Licensed Backhaul options
Title: Message Dustin, I'd like to see those screen shots. In case interested... I had reviewed the spec sheet of Andrews 3 ft, Gabriel 2ft, 2ftHQ, 4ft, 4ft HQ and compared. Understanding that this is theory based on spec sheets being accurate, this was my finding... 2ft HQ dish did great (best of 3) to prevent colocation interference. However, 4ft dish (regular) did much better at preventing front interference. However, Andrews 3ft, came pretty darn close to the performance of 4ft dish, at 3ft ease, price, and windload. Of course 4ft HQ dish beat them all in all categories, but at a hefty price and windload. Analyzing three sites in question, each site was better off with a different one of the antennas based on the need of the site. Site 1: The 3ft, needed high gain, some noise in front, but no other antennas on the roof. Site 2: The 2ft HQ, lots of colocation noise, but landlord not allow 4ft dish. (used 2ft over 3 ft, as msot noise was colocation based) Site 3: The 4ft HQ, lots of colocation noise, 4ft mounting OK, lots noise in front, and every db counts. I'm going to put them to the test next week when they arrive. Here were actual compulations from spec sheets, (averaged data). Degrees are number of degrees off center, not total beamwidth. 2ft compared to 2ft HQ aboutsame until...-60 deg off center,4 db more for HQ -90 deg off center, 12 db more for HQ.-180 deg off center, 9 db more for HQ summary: no benefit to combat front end noise. Great for colocations noise, and limited antenna seperation. 4 ft compared to 2 ft HQ 4 ft much better than 2ftHQ till 58 deg. at 7 deg, 4ft 9 deg betterat 40 deg, 4ft 5 deg better at 58 deg both antennas are equal at -32 isolation. at 90 deg, 2ftHQ -40 db isolation, 8 db better than 4ftat 180 deg, 2ftHQ -46db isolation, 4 db better than 4ft Summary: 4 ft better for front end interference.however, 2ftHQ still significantly better for colocation noise. Andrews 3 ft - 4ft at 7 deg, 4ft 9 db better than Andrewsat 10 deg, 4 ft 5 db better than andrewsat 20 deg, 4ft 8 db better than andrews at 40 deg, both about the same at -32db.(steady slope to 90)at 90 deg, andrews -38, 6 db better than 4 ft. at 119-180 deg, both at about -42. Summary, 4 ft better for front interference (below 35 degrees).however, Andrews has equal colocation protection, and better verticle speration, and 4ft dbi, at 3ft ease and windload.

Many folks would choose to use other algorithms for queuing in high throughput links, but generally nagle is on by default. Clearly, some form of queuing is desirable for maximum throughput of small packets, but more interactive applications are hurt by queuing e.g. VoIP. Therefore, it is useful to see what throughput is obtained with and without the setting on if you are considering using the radio pair for VoIP.

RE: [WISPA] Licensed Backhaul options
Title: Message Charles you make a good point, but I’m going to throw a “but” in here: but the Orthogon / Canopy 300 radio’s will run also run at: 64 QAM .92 dual -62 receive sensitivity +18 output (252.9 throughput) 64 QAM .75 dual -68 receive sensitivity +18 output (206.7 throughput) 16 QAM .87 dual -71 receive sensitivity +20 output (160.8 throughput) Full list can be found in the release notes and if you do the math on those modulations you can get some very good performance. I do agree with you that the licensed links would make more sense, but hanging 4 foot dishes on towers becomes a very expensive task or if you have to do a non-penetrating roof mount skid, the cost difference between the sleds is big. So we have to take in more than the cost of the radio’s, licenses, leases and dishes but put together the total cost because if you are hanging BIG dishes you’re going to dig deeper into your pocket. Sorry I missed you at the show, I’m on baby watch so when she saw wireless beer and gear she called foul and took away my kitchen pass L.

The Spectra would be around $20k with external antennas. A licensed product is going to be at least that, and probably $5k more.

RE: [WISPA] Licensed Backhaul options
I'm looking at moving to a licensed solution to increase throughput across one of out backhaul links that spans 5 hops. Distances between hops range anywhere from 7 to 19 miles. Can anyone recommend a licensed radio manufacturer that should net us 50Mb-100Mb per hop? Hi Bobby, >From reading your post, I could surmise (to your detriment) that you missed the WiNOG conference in Austin last week. One licensed manufacturer was actually offering a show special for a FREE 100 Mb upgrade (e.g., buy the radio at the 50 Mb price but get a 100 Mb radio) to show attendees (this is worth thousands of dollars per link). That said, now that you've listened to my "snide remark" -- I'm actually going to provide some useful information (consider it the cost of free but useful advice =) To go 9-17 miles, you will have to use either the 6 or 11 GHz frequencies...FCC Part 101 stipulates a minimum dish size of 4' for 11 GHz, and 6' for 6 GHz -- the first question you must ask yourself is whether this doable for your towers/rooftops? Anyone who tells you that 18 GHz (which allows for a 2' dish size) will do the link for has no idea what they're talking about. I would recommend reading the following article put out by Broadband Wireless Magazine a few years ago helping WISPs understand Point-to-Point Licensed Links http://www.shorecliffcommunications.com/magazine/volume.asp?Vol=39&story=365 If you have any additional questions, feel free to ping me offlist -Charles --- WiNOG Austin, TX March 13-15, 2006 http://www.winog.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bobby Burrow Sent: Thursday, March 16, 2006 1:21 PM To: wireless@wispa.org Subject: [WISPA] Licensed Backhaul options I'm looking at moving to a licensed solution to increase throughput across one of out backhaul links that spans 5 hops.
