Re: [WISPA] OT - Patrick has left Alvarion
Wow Patrick, After thinking about how to congratulate you on a long successful and distinguished career and to offer you some thanks for being part of the last 10 years, which indeed has been a very exciting ride. Here's what came to my mind: (Think baritone and skip the mushy stuff) Memries, Like the corners of my mind Misty water-colored memories Of the way we were Scattered pictures, Of the smiles we left behind Smiles we gave to one another For the way we were Can it be that it was all so simple then?

Re: [WISPA] Trango Link 45
We have a large number of these radios in our network and are happy with them. WIth that being said, make sure you understand that the Trango link test uses 1600 byte frames.

Re: [WISPA] OT - Patrick has left Alvarion
Thanks Butch. It is actually a surprise to even some Alvarion insiders, many of whom did not know until last night when I sent a message to Alvarion folks. The name Sageni is a hybrid of the words sage and genie. I made it up. It is meant to imply something along the lines of the insights and knowledge you need and the can-do and at-your-service attitude of a genie. The pronounciation is simple -- say-gen-ee. No matter ones native language, most anyone from anywhere should be able to pronounce it. I spent hours one night thinking of names and hunting for an open URL. Amazingly, this simple six letter combo www.sageni.com was not taken. - Patrick On Tue, Jun 17, 2008 at 12:40 AM, Butch Evans [EMAIL PROTECTED] wrote: On Mon, 16 Jun 2008, Patrick Leary wrote: Sorry for the OT post, but I wanted to inform the community that I have left Alvarion after 10 years.

Re: [WISPA] modulation question
Bryan Scott brought up an important point: You can put QAM subcarriers on OFDM. But you can put almost any other type of subcarrier on OFDM too. That may be a confusing thing. OFDM is method of putting multiple FM modulated carriers on the air. Almost like sending multiple channels containing their own info and then combining all the channels at the far end. Those channels can have QAM subcarriers, but the RF is still FM modulated, not QAM modulated. That may be confusing to some. The FM modulation of OFDM gives it the inherent advantage of angle only modulation methods. Then there are systems that use QAM to modulate the RF. Those systems are less resistant to link problems but are one of the best ways to cram a bunch of data on the link. (V.90 dial up modems are a good example). When they added color to the BW TV signal, they used a QAM method. The original stereo AM radio signal was QAM.

Re: [WISPA] OT - Patrick has left Alvarion
Sorry for not getting back John. There is no cell phone coverage where we are temporarily staying (on the Weeki Wachee River) and I blissfully have not been checking v-mails. This is a gorgeous and little known part of FL, even though it is just one hour north or Tampa. It is the southern edge of what's called the Nature Coast. Crystal clear fresh water rivers bubble up from cracks in the lime stone. Deer, bear, bobcats, otters, manatees and ospreys are all around. Just two minutes ago my little girls were two feet away from a manatee sow and her calf (manatee swim by here many times a day).

Re: [WISPA] modulation question
what is a sub carrier? For IP guys, think of VLANs. You can cram a bunch of VLANs on an Ethernet link. Each VLAN appears to be its own Ethernet link. But to the trunk, all the VLANs appear just to be payload data. Same thing with RF. The on-the-air signal is modulated. OFDM or FM (or morse code or AM or whatever) method. That is the Ethernet. Inside that modulation, if you pick it apart, you may find the raw data (like Canopy does) or you may find other modulated signals (like the VLAN) that have to be further demodulated (QAM on OFDM like Orthogon). QAM methods are used to cram a ton of information on a link. Whether it is on the raw RF signal on in a subcarrier. But they are not as robust as simple direct modulation.

[WISPA] Sandbagging the levy
OK, I fill in one hole and another appeared. (Thanks Brian) I honestly don't know if Orthogon puts the QAM directly on each discrete RF carrier of the OFDM scheme or if those carriers are FMed with a subcarrier containing QAM. So, let me retreat to a previous statement that I still believe to be correct: OFDM does not have any relationship with QAM. (I have CODFM on the brain as that was a superior method of doing OTA HDTV but the ATSC selected 8VSB. But that was in another life...) OFDM strictly speaking only means taking a channel, transmitting multiple RF carriers within that channel. The frequencies are calculated such that there is a minimum of interference between them. Those individual RF carriers are (I discover) commonly refered to by some(most) as subcarriers. Strictly speaking, they are not subcarriers in the classical sense but that is a whole other discussion. I will concede that using the term subcarrier is in common use but is not accurate. (It really depends on what they are doing at the baseband level, so I might be wrong about that opinion as well.) The second channel (R-L) of an FM broadcast signal is on a subcarrier. Color of NTSC video is a subcarrier. Musak is on subcarriers of FM broadcast channels. OFDM bearer channels (howz that for mixing technologies) are discrete RF carriers. But since my opinion of the use of the term subcarrier is in an antiquated minority, I will yield that the term is the commonly accepted method of referring to those carriers. Gheeze it is hard to change.

Re: [WISPA] Sandbagging the levy
In Quincy, we had one of the few levees that held until a nut went over and pulled some bags off the top and made it fail on purpose. He had recently been released from jail after serving a term for arson of a school. The local TV station interviewed him as the breech was happening and he was acting like the hero and claiming he was trying to fix the problem. However local levy officials had just visited the very area and said it was one of most sturdy parts. As I recall, a news helicopter or someone actually got footage of him pulling the bags off. He was charged with causing a catastrophe. A local entrepreneur floated a barge over to West Quincy for the purpose of turning it into a restaurant after the water receded. I don't know if that happened or not. Not that any of this has anything to do with WISPA... - Original Message - From: Victoria Proffer [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Tuesday, June 17, 2008 9:14 AM Subject: Re: [WISPA] Sandbagging the levy I believe the 93 flood was called the 100 year flood.

This is a big step for you Patrick. I, for one, and glad you are taking it. Your insight and passion are a great benefit to anyone you work for/with. Having the Entrepreneur perspective to go with your corporate insider experience will make your future advice even more valuable. If there's anything I can do, please do not be afraid to ask. And boy will the questions come out of the woodwork. Being on the front side of the paycheck is a whole lot different than signing the back of one! Silly things like professional insurance, should I get that new tool or that new stove etc. are much harder decisions that one would think! (Said the one that just surprised his wife with a 65' bucket truck instead of carpet! sigh) Once you get over the shock of seeing your savings dwindle, hounding people for the money they owe you etc. you'll love working for yourself. It's great to be able to take off work to take the kids to ball games etc. and not have to beg anyone for permission. I miss very few of the things that my kids do. Take care and enjoy your summer.

[WISPA] Press Releases Decision
The WISPA board has discussed this matter of Unauthorized Press Releases on the WISPA listservs. Our consensus is that if any WISP or Vendor wants to make Press Releases they should send them to Rick Harnish [EMAIL PROTECTED] or Matt Larsen [EMAIL PROTECTED] for release on the WISPA Homepage. People that want to read the press releases can do so on the website without cluttering up everyone's email box and using excessive bandwidth to send these out. We will allow postings on the WISPA listservs which include a link to a private webpage which contains the Press Release or a link to the WISPA homepage. This decision should adequately solve everyone's goals and issues with minimal disruption. If Matt or I are not reelected in the upcoming election, I will notify the list for who the responsible party will be. The WISPA board will also reserve the right to decide which press releases are to be published and which are to be denied. We will not post financial information about a company on the webpage.

Re: [WISPA] modulation question
Chuck, Nice posts! Thanks for the clarification.(PS. I clearly had some misunderstanding/FUD in my last post, regarding QAM.) While you are at it Can you comment a bit on OFDM, regarding the math, of what occurs to power levels as it divides into subcarriers and recombines on the receive end. There was a good post on the STAROS forums about it a year or so ago, but I couldn't find it again to repost to this list. It brought forth some relevent info on how to correctly do link budget calculations and what RSSI should be expected considering OFDM versus DSSS style gear.

For IP guys, think of VLANs. You can cram a bunch of VLANs on an Ethernet link. Each VLAN appears to be its own Ethernet link. But to the trunk, all the VLANs appear just to be payload data. Same thing with RF. The on-the-air signal is modulated. OFDM or FM (or morse code or AM or whatever) method. That is the Ethernet. Inside that modulation, if you pick it apart, you may find the raw data (like Canopy does) or you may find other modulated signals (like the VLAN) that have to be further demodulated (QAM on OFDM like Orthogon). QAM methods are used to cram a ton of information on a link. Whether it is on the raw RF signal on in a subcarrier. But they are not as robust as simple direct modulation.

But you can put almost any other type of subcarrier on OFDM too. That may be a confusing thing. OFDM is method of putting multiple FM modulated carriers on the air. Almost like sending multiple channels containing their own info and then combining all the channels at the far end. Those channels can have QAM subcarriers, but the RF is still FM modulated, not QAM modulated. That may be confusing to some. The FM modulation of OFDM gives it the inherent advantage of angle only modulation methods. Then there are systems that use QAM to modulate the RF. Those systems are less resistant to link problems but are one of the best ways to cram a bunch of data on the link. (V.90 dial up modems are a good example).

This is not just a random number picked. Someone else will probably explain it better, and I welcome them to, but for now I'll try :-) It has something to do with how OFDM takes the signal and breaks it up into lower powered sub carriers. As modulations are higher, they get broken down into more sub carriers, hence QAM 32,64,256, etc. I believe it has something to do with how the math works with Watts versus DB, when the signal gets split and added back togeather again at a later process. There are two side effects that come... As higher modulations are used, it more work for the card and Transmit power becomes less, and receive

[WISPA] How much data

Re: [WISPA] modulation question
Each system is different as to the number of carriers and a different number of modulation levels on the carriers. Basically it is Shannon's law which defines the maximum rate of data that can be transmitted over a channel. But no real system can hit the Shannon limit. The imperfections in the demodulators vary from manufacturer. The simple answer is the more you try to pump through, the more signal you need. Shannon's law contains a signal to noise ratio as one of the components. If you want to have more throughput, you have to have more signal or less noise. The short answer is, read the manual. I would hope they are all conservative on the published signal levels needed for the different bit rates. As far as DSSS goes, I really don't know if the Shannon formula applies or not.

Thanks for the clarification.(PS. I clearly had some misunderstanding/FUD in my last post, regarding QAM.) While you are at it Can you comment a bit on OFDM, regarding the math, of what occurs to power levels as it divides into subcarriers and recombines on the receive end. There was a good post on the STAROS forums about it a year or so ago, but I couldn't find it again to repost to this list. It brought forth some relevent info on how to correctly do link budget calculations and what RSSI should be expected considering OFDM versus DSSS style gear.

For IP guys, think of VLANs. You can cram a bunch of VLANs on an Ethernet link. Each VLAN appears to be its own Ethernet link. But to the trunk, all the VLANs appear just to be payload data. Same thing with RF. The on-the-air signal is modulated. OFDM or FM (or morse code or AM or whatever) method. That is the Ethernet. Inside that modulation, if you pick it apart, you may find the raw data (like Canopy does) or you may find other modulated signals (like the VLAN) that have to be further demodulated (QAM on OFDM like Orthogon). QAM methods are used to cram a ton of information on a link. Whether it is on the raw RF signal on in a subcarrier. But they are not as robust as simple direct modulation. But there is always a tradeoff. The following is not really accurate but it may give a data guy another way of thinking about it.

But you can put almost any other type of subcarrier on OFDM too. That may be a confusing thing. OFDM is method of putting multiple FM modulated carriers on the air. Almost like sending multiple channels containing their own info and then combining all the channels at the far end. Those channels can have QAM subcarriers, but the RF is still FM modulated, not QAM modulated. That may be confusing to some. The FM modulation of OFDM gives it the inherent advantage of angle only modulation methods. Then there are systems that use QAM to modulate the RF. Those systems are less resistant to link problems but are one of the best ways to cram a bunch of data on the link. (V.90 dial up modems are a good example). When they added color to the BW TV signal, they used a QAM method. The original stereo AM radio signal was QAM. Cable modems use QAM. - Original Message - From: Chuck McCown - 2 [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Monday, June 16, 2008 11:15 PM Subject: Re: [WISPA] modulation question I think some disambiguation may be in order. QAM is a vector modulation method:. http://en.wikipedia.org/wiki/Constellation_diagram It shares almost nothing with OFDM methods. Irrespective, all receivers (CW, AM, FM, SSB, VSB, angle modulation, OFDM, QAM, TCM, etc) can have an RSSI output from the AGC, limiter or demodulator. Strictly speaking it only means Received Signal Strength Indicator. It is modulation agnostic. It is not related to the modulation. - Original Message - From: Tom DeReggi [EMAIL PROTECTED] To: [EMAIL PROTECTED]; WISPA General List wireless@wispa.org Sent: Monday, June 16, 2008 10:10 PM Subject: Re: [WISPA] modulation question I'm not sure exactly your question?

Re: [WISPA] mission critical 100Mbps links
Dragonwave has been our best radio ever. 18ghz with 2ft dishes shooting 13 miles for 9 months without missing a single ping. We push about 50Mbps across it daily. Trango also has their 18ghz product that is less money than Dragonwave. You can purchase a Trango 100Mbps 18ghz set with 2ft dishes for less than $15k. Upgrade to 300Mbps full duplex is $3,000 extra (software key, so can be added later). Travis Microserv RickG wrote: Any opinions on 100Mbps radios for mission critical 100Mbps PTP links?

Re: [WISPA] mission critical 100Mbps links
How critical? Harris Constellation full hot standby space diversity is about as mission critical as you can get with microwave. That would be licensed. A little less critical would be Dragonwave. We use them and love them. Put up a double set redundant system with STP. Trango 18 GHz stuff seems to be working well for us as well. Lower cost. Again, redundant with STP/OSPF type of stuff. Then lower cost yet would be Orthogon. You can get 100 Mbps on all of those (at least I think you can on the Trango, not totally sure). If this is a link that is involved in launching nuclear missiles or keeping air traffic control operational, I would bury fiber backed up with Harris.
