Re: [Repeater-Builder] Re: 802.11b wireless
Nate is correct in that the frequencies listed were the center freq of each channel. There are 14 channels. And yes, I forgot the decimal. Oh well I am old as well as tired. The channels overlap each other in that they are 22 MHz wide ( NO decimal) One can do the math and see which channels edge falls outside the Amateur band if you wish but if you do not run an amplifier, who cares. If my memory serves me 802.11 concept began in the late 80's and there were two forms approved by the FCC. One was DSSS (Direct Sequenced Spread Spectrum) that is used today and the other was FHSS (Frequency Hopping Spread Spectrum) that consisted of 75 channels spaced 1 MHz apart and traffic jumped between those channels. In 1999 the industry selected 802.11b as the standard with its max 11 Mbps. Of course we now have everyone pushing the 802.11g that have a maximum of 54 Mbps but we seem to forget that many access points use 10 base T Ethernet connections so you are limited to 10 Mbps anyway. Remember as the signal gets noise due to low signal strength the speed is decreased. I use 802.11g but often have only Mbps speed due to low signal strength. Still pretty fast as I have seen T1 that was only slightly higher is speed. With a good antenna it possible to get amazing distance. I have sent video with p1 picture to my brother Jim,KA8HAK over in Akron 16 miles from me. I was using 1 watt into 140 feet of 7/8 hard line to a 3 foot dish at 85 feet. He was using a home brew 44 element linier yagi on a tripod 7 feet in the air fed with LMR400! Until last year I had an FM repeater (2.411200 out / 2.431200 GHz in) on the air. It also ran 1 watt and had a 20 meg split. Worked pretty good but there were only three of us that could transmit. Jim KZ5AW, my brother Jim KA8HAK, and myself. Perhaps one day I will put it back on if equipment become more reasonable and others become interested. Oh well - enough of the rambling and at least I said something about repeaters.. 73 P.S. Nate, I am glad I gave you a laugh at the no decimal. One of my goals is to make someone laugh each day even if they are only laughing at me! It was a good day as is most of them..

That channelization map only shows the CENTER frequency of the direct-sequence spread-spectrum channel you're using. I believe Mr. Reese is incorrect in his statement that channels 7 and 8 are in the ham band. Each channel overlaps the channels around it -- they're wide. (Our old pal Nyquist's pesky theorem might point out that there's not enough bandwidth between from say, 2417 to 2427 to do a 11Mb/s data stream on Channel 3, and that's assuming you would run right up against channels 2 and 4. But, I sure as hell can't do the math without having had any coffee yet today!) The access points just deal with the interference they cause each other. When you're laying them out for use in an office building, you pick patterns that use 1, 6 and 11 to keep all the AP's out of each other's hair. Channels 1, 6, and 11 are the only channels that don't overlap each other in the U.S., so channel 1 extends up through Channel 3 (and below channel 1 down to just above 2400 MHz), and Channel 6 extends downward to Channel 4 and upward to channel 8. So the highest usable channel if you want to operate as a Part 97 station is Channel 6 if I didn't screw up my math. Or the top portion of your signal will be out of the ham allocation. ;-) I got a kick out of the 24XX GHz label too... that's pretty high! (GRIN) Nate WY0X JOHN MACKEY wrote: It should be noted, also, that the channels are overlapping on each other. The only channel setup that would NOT be overlaping it using channels 1,6, 11.

RE: [Repeater-Builder] Re: 802.11b wireless
Kevin, I am doing exactly the same thing to get internet out to the hamshack... using 12dB Cushcraft collinear cheapies, with my callsign VPN. It is also operating in the ham band. Probably wouldn't pass the test if push came to shove. The link is only used for call lookups monitoring the DX clusters, although I had plans for a weather station next year. I wonder how VPN fits into the mix? Does that count as encryption? Kind of a grey area... I had the extra gear from a network re-build at the office and decided to put them to some use. Not throwing rocks or anything... I just feel it is sometimes better to be wary of receiving a NAL. I have heard some rumblings of TCP/IP experimentation in the ham bands, but no details as of yet. It is a subject I am very interested in. There would be numerous uses for that concept as it relates to our hobby. Hopefully someone can shed a little light on the subject as I am certainly no expert in this arena. As for the Sipura boxes, the only knowledge I have of them is that they fit the bill we needed them for. My line of thinking was that if you could build an interface then it might be worth some effort. It sounds as though Steve has a much better handle on things than I do. Maybe he should take the point and impart some guidance. Thanks to Richard for his input. My 2.4gig ATV gear wipes the link out... ;-). I had no idea there was this kind of interest in this subject!

i support 2.4 ghz communication data wise as long as its for amateur use only , i know ppl dont want to think about legaities in the ism band but itsnt the same as pirating a call and slammin 80 meter , anyhow i have several proven ideas on long range point to point 50 + miles , and some few manufacture links , and simple wireless node repeaters for passing data , much likethe days gone by the big big packet networks that faded in the dust , and the best part is it works just as well at 10 mwas 200 mw non licence and i bet swell at 100 watt full amateure power on us chan 1-6 with call sign of course , her ein the hills of PA NLOS is a real problem , lotta cracks to fill with signal for true 11 mbps wifi Russ N3TIH - Original Message - From: Tedd Doda [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Wednesday, December 08, 2004 7:54 PM Subject: Re: [Repeater-Builder] Re: 802.11b wireless On Wed, 08 Dec 2004 18:26:21 -0500, Kevin Custer wrote: however feel free to discuss the technical nature of the subject in any detail here.

Re: [Repeater-Builder] Re: 802.11b wireless
Careful! That channelization map only shows the CENTER frequency of the direct-sequence spread-spectrum channel you're using. I believe Mr. Reese is incorrect in his statement that channels 7 and 8 are in the ham band. Each channel overlaps the channels around it -- they're wide. (Our old pal Nyquist's pesky theorem might point out that there's not enough bandwidth between from say, 2417 to 2427 to do a 11Mb/s data stream on Channel 3, and that's assuming you would run right up against channels 2 and 4. But, I sure as hell can't do the math without having had any coffee yet today!) The access points just deal with the interference they cause each other. When you're laying them out for use in an office building, you pick patterns that use 1, 6 and 11 to keep all the AP's out of each other's hair. Channels 1, 6, and 11 are the only channels that don't overlap each other in the U.S., so channel 1 extends up through Channel 3 (and below channel 1 down to just above 2400 MHz), and Channel 6 extends downward to Channel 4 and upward to channel 8. So the highest usable channel if you want to operate as a Part 97 station is Channel 6 if I didn't screw up my math. Or the top portion of your signal will be out of the ham allocation. ;-) I got a kick out of the 24XX GHz label too... that's pretty high! (GRIN) Nate WY0X JOHN MACKEY wrote: It should be noted, also, that the channels are overlapping on each other. The only channel setup that would NOT be overlaping it using channels 1,6, 11. There are also channels 12, 13, 14 but they are not authorized in the US. -- Original Message -- Received: Wed, 08 Dec 2004 07:24:15 PM CST From: Richard D.

There would be numerous uses for that concept as it relates to our hobby. Hopefully someone can shed a little light on the subject as I am certainly no expert in this arena. TCP/IP over AX.25 (encapsulated) was working in the late 80's, and became fairly popular in the early 90's. (AX.25 being the protocol more typically called Packet Radio by most hams.) Worked well. In an insightful move, early Internet hams also allocated us addresses in the global address allocations. The entire 44.0.0.0/8 TCP/IP address range is still allocated world-wide to Ham Radio on the Internet. TCP/IP over Packet was speed-limited by the modulation type(s) and radios used, so by todays standards it was very slow. Some folks did move on up to microwaves and push the speed limits up, but most hams playing with IP-over-Packet used UHF where they could cram 9600 bps through a standard UHF FM radio if they pulled the receive audio off the discriminator and were careful about levels on the input side. On VHF, 1200 bps was common. Both were typically set up half-duplex, although with a little ingenuity and more radios, point-to-point links didn't have to be. TCP/IP over Ham Radio is getting a bit off-topic for Repeater-Builder, but if you have any questions I can point you to some other lists and resources off-list. Fire me off a note. Nate WY0X Yahoo!

I've yet with play with that stuff, but it sounds to me like a pair of gain antennas at each end could get you a couple of miles to where you would have wired internet access. Anyone try this? Bob NO6B I have a 6.65 mile non-line-of-site path to bring internet access to my home from the center of town where our T1 line exists. I use 802.11b (2.4 gHz) with larger grids (about 24 dB gain) on each end. There are different cards available these days that have better receiver sensitivities and more power, however, they are illegal for operation when used in non licensed applications. I simply programmed the cards to operate in the ham portion of the band and used my callsign for the SSID. I do not want other peoples opinion on the legality of running internet that is encrypted over the ham band, as I really couldn't care about someone else's opinion on my operation, however feel free to discuss the technical nature of the subject in any detail here.
