Hot Rod spewed twice, yet, on this subject.
Obviously, I'm not communicating well... As a computer guy I'll tell you to have a look at hawking antenna's BUT I The antenna part isn't a problem. I have a Hawking antenna, quite directional, totally unsuited to swinging at anchor, on the hard. It works just fine, connected via active USB (didn't I already say that???) to my laptop, and I can talk on the boat with any of several unencrypted locations. I don't like it because it's connected to my computer. I'm looking for a wireless solution.. don't think that what you are trying to do is possible. Normally when you try and do a long distance with high gain antenna's you need a high gain antenna at both locations, you also get into using omni or unidirectional antenna's. Even with line of sight and a unidirectional antenna anything over a few Kms is getting crazy. SORRY I'm not trying to get over a few klicks. Just from the harbor up the hillside in the Caribbean will suffice just dandy. If I can "see" it I should be able to talk to it (23dBm) and hear it (8.5dBi, say, to keep the donut fat enough). My challenge is to get the signal not only out of the boat, but down to my laptop, wirelessly. I can do one or the other brilliantly. So far I haven't done both in one box. So, as the computer expert, leaving the challenge of antennas to me, what (12 V input, thank you very much) device does what I need? I'll figure out how to antenna it and elements-protect it. Later today you also said: Don't argue with this but your not going to get access to a WIFI hotspot at Star Bucks.... If the idea is to cruise the coast an get signals, "GOOD LUCK" I have no intention of trying to find Starbucks on evey little island. It was a rhetorical example. I don't even like Starbucks, let alone go into them, but lots do, so I used that example. I digress... But I have reason to believe that there may be a number of homes running wireless broadband in an unencrypted mode anywhere I might throw out the hook. Certainly, I and all of my neighbors' installations are that way. Pop off into the lake (where I'm waiting to rehab my shoulder, and live when I'm not working on the boat, or until the optionee takes it out from under me, whichever comes first), fire up my laptop, and point my Hawking at my house and I get signals enough to light my way home at night. Turn a bit and see the same result from my two-doors down neighbor. Take out the Hawking and just use my internal, and it's lots less. But I see 15 open connections well enough to surf. Do a google on "warsailing" and see a guy's site talking about a waterway where he lives. Can't see the chart for all the circles! So, in radio terms, I say again: What 12V device will allow (consider it just out to my dock, with me and my laptop on the adjacent shore if you can't deal with me seeing further) me to sit, and talk, to my remote (up the hill about 200 feet from the dock, after all) hotspot (unencrypted broadband source), with my laptop with its internal wifi card? Disregard that I also see my neighbors with my internal card at this distance - I want to use the single device for my communications, let's say, because it's got this cool interface for determining signal strength, or for allowing me to choose, or for switching automatically if one gets weak, or any other reason you may prefer than listening on my internal card, directly. I await your learned response, having no luck elsewhere, so far.

Skip, no need to limit yourself to 12 volt devices as long as they have
110 volt adapters. The price of small inverters is down to about $30 and they work fine. I have several on my boat for powering laptops, charging cell phones, etc. |

You might have a look at some of the many websites about building wireless community networks. There's even a book of that title on O'Reilly press these days. These places will be where pushing the limits or 802.11 gear is routinely discussed. There are links to some such networks at: http://en.wikipedia.org/wiki/Wireless_community_network For what you are proposing, as I understand it, two antennas/interfaces seems to be the go. If you consider they are doing different jobs, it makes sense. It's only a pity the masthead device is USB: if it were ethernet, all you'd need would be an inexpensive wireless AP that is also an ethernet switch. As a bonus, any non-wireless computer you subsequently installed onboard would have a wired switch port to connect directly to. Also note that you're not restricted to devices that come with supply units that can run off 12V: most devices like this have extremely modest demands and dc-to-dc supplies of various capabilities are readily available. --Damian |

Amazing that I'm even willing to respond after such a ****y response, do you
want help from people here or a flame war? You should be able to look at almost any router / bridge out there. If you flip them over you will notice that all of them run on a lot less than 110V. I currently use an APC (Backpack) that has a small inverter (12V) that can power or charge my laptop, PPC, cellphone and run a wireless router all from one cigarette lighter. The voltage on my linksys routers are around 5v. I'm not sure I've seen a solution that will do what you are asking for, you might consider a small router and hawking antenna up on the mast with only the 5v to power everything up.

Following up my own post to combine replies' feedback.
First, let me say thank you for the ideas which are starting to flow from this exchange. Still no answers, but at least ideas pertinent to the question. So, to the current crop: From: Skip, no need to limit yourself to 12 volt devices as long as they have 110 volt adapters. The price of small inverters is down to about $30 and they work fine. I have several on my boat for powering laptops, charging cell phones, etc. Actually, I'll have plenty of AC. I just want to limit the amount of stuff I have to do and clutter I'll create. Running two wires up the mast just makes it more difficult. Of course, any device will no doubt have an adapter, because they're not designed for remote powering, usually, or accomplish it via POE. Given that Cat5 has 4 unused points, I could actually have three different power levels as long as I didn't mind a common negative, and wasn't concerned for solid strand tiny (and untinned) wires trying to carry an amp about 100 feet by the time we're finished with sourcing and running the power up the mast :{)) From: "Damian James" On Mon, 15 Aug 2005 17:59:27 -0400, Skip Gundlach said: ... My challenge is to get the signal not only out of the boat, but down to my laptop, wirelessly. I can do one or the other brilliantly. So far I haven't done both in one box. So don't.

The requirement then isn't whether the high-gain kit can send a usable omni signal too, but whether it has an ethernet interface. Well, actually, that is a problem. The two I had, one wireless AP, connected via cat5 to the bridge, constantly was in some sort of conflict. Putting these two next to each other on the bench, connected to each other with cat5, shouldn't engender conflict messages (should it?). As to omni signals, that's an antenna function, and easily solved. You might have a look at some of the many websites about building wireless community networks. There's even a book of that title on O'Reilly press these days. These places will be where pushing the limits or 802.11 gear is routinely discussed. So far, all I get is talking to like units for range, and those in between can also see the signal. My problem has been to have an omni-talker (vs omni-directional) setup, as well as the conflict issue. However, if you can direct me to something which relates to a wifi computer talking to some single device which can see APs in other (diverse, not the same equipment, unencrypted) locations, that (I think) is what I'm looking for. To recap the original, the AP and Bridge were Senao 200mw 2611 deluxe units, connected via cat5, both 12V. Not elucidated, I don't think(recall), was the AP had a (5+dBi) rubber duck to see me (and any others who looked with their wifi setup) and the bridge had an 8.5dBi stick to see and talk to places far away. Never got to talk to each other on the bench, let alone up the mast. Always a conflict whenever I connected the two together, regardless of the IP configuration(s) used. There are links to some such networks at: http://en.wikipedia.org/wiki/Wireless_community_network For what you are proposing, as I understand it, two antennas/interfaces seems to be the go. If you consider they are doing different jobs, it makes sense. It's only a pity the masthead device is USB: if it were ethernet, all It's not. It's straight 12V, with wireless signal. My *cockpit* antenna is USB. If I didn't mind having my computer connected via ethernet, the bridge would work fine. I want a wireless solution. Putting an AP at the nav and running the ethernet up the mast doesn't solve the problem, as it can't even do it on 4" (the custom one I built) or the standard 3' pigtail, on the bench. you'd need would be an inexpensive wireless AP that is also an ethernet switch. As a bonus, any non-wireless computer you subsequently installed onboard would have a wired switch port to connect directly to. Well, yes. As above about wired connections/wireless goals. So, is, somehow, the Senao unit unsuited to the job, being only either AP or bridge? I'd sure love to do some cheapie solution rather than the more expensive one currently trying to talk to the bridge! Also note that you're not restricted to devices that come with supply units that can run off 12V: most devices like this have extremely modest demands and dc-to-dc supplies of various capabilities are readily available. Agreed. However, as above about simplicity. See more below... From: "Terry Spragg" Skip, packet switching should seek out survivable routes for each packet. I'm sorry, but I'm not knowledgeable enough to get the connection here. I don't think routing is the issue, though, if system conflicts are caused by routing problems, perhaps that's an attack I can follow. Currently, I've disputed the amount with my credit card company, who's temporarily credited against the supplier, who says 'it isn't convenient for me to provide technical support at this time' - but has, in the past, worked with me to try to sort this out (unsuccessfully). If there's a solution which will allow me to keep these two units (fine, powerful ones) and make them play nice, I'm happy to do that. Late to join, sorry if I just missed some basic to this proposition. Why not just use an antenna cable about 6 feet up the mast to avoid long AE run losses at giga frequencies, use two wireless hubs below decks, with one AE on each side of the mast? Ethernet them together and let it fly? I wonder if software would handle switching well in a yawing environment, linked to shore. Seems to me the internet was designed for multi routing and survivability. On a dock or two anchors, you could replace the shoreside omni with a steerable beam if you needed longer reach. (Sorry to rub your shoulder wounds the wrong way;-) Heh. No problem. I very much doubt I'd need more than the antenna setup I've envisioned, and anything more than omnidirectional is more work than I want to do, so it's moot, anyway. As to two antennae shortly up the mast, as Larry is fond of saying WRT antennae, height is your friend, so mast-top it is. Getting the signal there wants to be wireless, though I could, per above discussions, get my AP to the bridge that way (ethernet) if it were necessary. Another item, mentioned in other commentary before, is that this would also serve other cruisers in the area, as they'd see my AP and be able to use it as well, as I'd intentionally leave it open (more below). Might need one wireless router to act as a hub, the other as gateway. What would happen if you moved a wireless laptop around on deck while connected? Packet switching is a wonderful tool. That was exactly the idea. Not necessarily to be moving around, but not to be connected by wires, and to be anywhere on deck, or even in the dink at the nearby shore, for example. However, just to be sure I'm on firm ground with the terminology, are you suggesting *3* units, two of which can talk to the bridge (point to multi-point)? D-links need 5 volts. You can get that from 12 volts. I wonder at range and antenna directivity effects of the mast reflector element. As it happens, that's what came with the setup first, returned for extra-cost upgrade to the second Senao unit (to solve the voltage difference and simplify powering). Certainly, if the antenna were next to the mast, it would change the pattern of an antenna severely. In my setup, I'd use the stick out the top (no antenna shadow/reflection) and the duck out the bottom, or perhaps the side (the better to see on deck, belowdecks). However, in close proximity like that (75 feet max anywhere aboard), even putting the duck on the top should work, I'd think. It's nice to have multiple redundancy at sea. The nearby fleet could share any connections all around a mooring. Kids might be happy to net game on rainy anchorages. That's about what I had in mind. I think I'd make it stealth, rather than advertise that it was my boat, in the event that any governmental agency might get upset about it, but the end result is just what I was thinking. and, finally... From: "HotRod" Amazing that I'm even willing to respond after such a ****y response, do you Heh. Amazing that I should have responded at all given the obliquity and non-connectivity. But I did say I was grouchy from the pain. Long timers here recognize that I have a low tolerance for digression, and reflexively change topics when it's not the one which started. Perhaps, despite my spelling corrections in my title, it's time for that again so folks don't get lost in the forest (this thread is almost long enough to engender guns or anchors at some point soon). So, since I don't recognize your handle, I presume you've not been around long enough to recognize me for what and who I am. Likewise, me, too, for you. Perhaps we'll learn to live with each other... want help from people here or a flame war? You should be able to look at almost any router / bridge out there. If you flip them over you will notice that all of them run on a lot less than 110V. I currently use an APC (Backpack) that has a small inverter (12V) that can power or charge my laptop, PPC, cellphone and run a wireless router all from one cigarette lighter. The voltage on my linksys routers are around 5v. I'm not sure I've seen a solution that will do what you are asking for, you might consider a small router and hawking antenna up on the mast with only the 5v to power everything up. Ah, but you see, that's exactly what I'm trying to avoid. As above about the wiring. Perhaps a router might do the job that an AP would not? I really would like to be able to give others access, too, which makes it seem necessary that the router also be an AP. The Hawking antenna is USB, and not nearly the power I envision, not to mention that it's highly directional. However, I really don't care what solution there is, so long as it's set-and-forget. Being ****y again, I don't recall ever saying I had a problem with 110 volts in any unit I'd looked at. I just don't want 48V (one recommendation), 5 and 12 (your situation) or other complications to running a suitable grade line up the mast to power whatever I've got up there with 12V. To recap, I want to be able to communicate with wireless stations ashore, which my laptop antenna can't reliably do on its own. I *could* connect to the Senao bridge via ethernet and, with a big stick, make that connection. But I want to do it wirelessly. What I've been told (which may well be wrong, but it's by a supplier from which I expected to just buy a bridge from, thinking the antenna would see me and the shore easily) is that I need an AP for my computer, and a bridge for the shore, both connected and talking to each other (thus the pigtail between the two units I have in hand) as well as outbound in both directions (deckside/dink/harbor and shoreside). Sorry if I ruffled your pipes. I'm just frustrated and in pain and without even my own computer, it being off for nav upgrade.

Just a thought: you've got the orientation right with the cat5? Connecting two hubs/switches together requires that either 1) one or both network devices has the capability to auto-detect the orientation of the cable; or 2) you use a crossover cable. This is also required connecting two computers without a hub/switch. Crossover cables will have pins 1 and 2 switched with pins 3 and 6. That would be: w/g g w/o bl w/bl o w/br br on one end, and: w/o o w/g bl w/bl g w/br br at the other end. I'm reluctant to mention it because probably you've got this part sorted out. But it's certainly a show-stopper if you haven't. If this is ot hte issue, then what exactly do you mean by "conflict"? You mentioned messages of some kind? --Damian |
