Cutting the wire (was) WiFi connectivity afloat - other usenet sites/URLs sought
A brief review, and, perhaps, a restatement of the problem (left below for
newcomers) in a different light which might get some of the creative minds here going in a different direction. I've got this neat bridge (Senao 2611DB3 Deluxe) in a NEMA enclosure atop the mast, with an 8.5 dBi antenna connected to it via a 6" pigtail (virtually no signal loss). It's 200mw, so it reaches out really far (23 dBm). It's antenna is omidirectional so it doesn't matter which direction the boat's pointing. The signal pattern is fat enough to cover sea level to many hundred feet high from the typical anchoring location. It's point-to-multipoint so it can see any available "visible" access point. Because my XP network program controls for me, I can select which of the available access points it sees that I want to talk to. Connected to my computer via ethernet, and powered with 12V via separately appropriately sized wire, both up the mast, it sees a WAAAY farther than the card in my laptop would, allowing me a great deal more latitude in finding a usable signal when I'm at anchor, wherever that may be. However, I'd really like to shed the wired connection (the ethernet connected to my computer, as it's a laptop and I'd like to be able to carry it up on deck without a tether). Unfortunately, a bridge won't talk in both directions over the antenna. How can I get some other wireless device (one which can talk to my computer) to seamlessly (so I see my remote AP as though it were coming in via my laptop antenna) talk to my bridge? There may be a variety of voltages of whatever this device may need; I'll work out getting power to it, and, as long as I'm having more than one - Schaeffer fans from the northern US may recall that ditty? - I'll put it up the mast, in the enclosure, too, so there's essentially no distance between the two, in case that's of any issue. Can this be done? Can I put some other wireless device (that is, which can see my computer's wifi) in connection with my bridge, so I can see (and choose which of potentially many) a remote AP? If so, what is that device? Better, is there a device which already integrates those functions? Thanks.

To emphasize the point, I don't want to have to connect either a laptop or permanently mounted computer to a bridge (which would get the job done) via anything, ethernet, USB active cable, coax or otherwise. Even allowing a wireless AP/router below would not solve the problem, as I haven't found a pair which will talk to each other, and I don't want the complexity/extra wiring that would entail, either, if it would (work). Some sort of arrangement which would require proprietary eqiupment (Part A will talk to Part B only if they're both the same manufacturer, e.g, as I can't assure that any shoreside point would have that manufacturer) likewise isn't satisfactory. Amplification is a good thing (i.e. 200-1000mw) but the antennas are what most likely will get the job done, and I have that part handled. The problem so far has been that I can't find an AP and Bridge which will talk to each other. Surely there's something which will work, and can take common DC power up the mast? Since nobody here (or, at least, apparently so) knows of such a beast, can anyone point me to better forums on usenet, or websites, devoted to the subject? Perhaps some sites devoted to wardriving or the equivalent? It's a bit of a recursive loop, as not knowing what will actually accomplish the job makes looking other places for other solutions more challenging. Thanks for suggestions on other venues...

Another county heard from (original discussion left below for reference):
I called one of the antenna manufacturers (the same kind I have) to inquire about one of their ("complete marine wifi") setups, and got to talking with a tech. It's his assertion that without a computer connected to the bridge there won't/can't be any shoreside communication. Whether it was a dedicated tiny computer doing nothing else or a desktop acting as a relay point, somehow it's necessary to have that brain in between. Worse, at least according to him, it's necessary to have antenna wire between the(ir) amplifier and both the antenna and server computer. Note that I don't know if theirs is a bridge or just an amplifier... We wrestled with the problem for a while before concluding that - at least with the equipment they offered - it was necessary to have wire from a computer to the antenna. So, there's at least one mfr. who sez it can't be done. I'd hate to think they're right, but the consensus is building... Sorta a PS he Damian, Larry, et.al., thanks so much for the thoughtful responses. I'm buried at the moment so can't fiddle with it (trying to sell/empty the house and deal with some mechanical issues on boats which need both detailing and selling before departure from this house, shortly). However, I'll try to take the laptop out to the dock, along with a power cord and the units I have to play with the configurations which have been offered, this weekend. I'll come back to those posts when I have info.

Skip,
It's his assertion that without a computer connected to the bridge there won't/can't be any shoreside communication. If he means the computer must be directly wired to the bridge, he is just flat wrong. Here is a solution that is not quite perfect, but will work. Put only the bridge and antenna on the mast. Power it with power over the ethernet cable (POE) and you only have one wire to run up the mast. Put your access point or router any where you like down below. Now the onl;y catch is that when you want to change your connection to a different wireless server, not really all that often, you will need to unplug the ethernet cable from the access point and plug it into the computer. Reconfigure the bridge to the server(ssid) and swap the cable back to the access point. It's a little painfull for me since my bridge won't let me browse for available networks--I have to know what is available, but you shouldn't have to. "Skip Gundlach" wrote in message ...

L8R Skip, about to enter active rehab, the sooner to get back to active refit and eventual launch! Skip, I believe your answer will be another computer cat 5 connected to the wireless and having another wi fi card and antenna at deck level to talk wirelessly to your portable. A 1" rack space server would do. I do not know exactly what software this base boat processor would need, but suspect you may need to go so far as remote console supervisory control over the "boat base station processor", similar to that used in computer classrooms. You would select the base server as your link from the portable, and work as the net manager on remote access. You would need complete access from the remote to the base server, and should use a crypto link. It would emulate a backbone for your intranet wan. You will need to manage the base firewall / gateway. I'm out of date, retired. Sorry I can't be more specific. Terry K |
