Let's get rid of NMEA

Then a Protocol Converter that can translate between the two Protocols in question, BiDirectionally.... -- Bruce in alaska add path after fast to reply I have this silly dream of a wifi network you just plug any DHCP-enabled device into 12V. The "marine router" connects to it and assigns it an DHCP IP, then makes a connection to its port 12345 and presents it an automatic broadcast of every data statement being received at the router. In that data stream is the IP and ID data of every instrument available. When you turn on the new Wind instrument, the router reports to all connections the new wind instruments ID/IP and starts feeding the wind data to the broadcast stream. Even your handheld walkie talkie, pocket GPS, tablet computer, laptop, etc., all connect to the boat's network. The walkie talkie can display lat/long/wind/course/speed/distance to waypoint....any data that's available...right on the walkie screen. The chart plotter in the hand held GPS shows the same data as the one at the helm or on the nav software on the computer. It all exists with off-the-shelf hardware. Software for it exists or is easily written in Linux, holding down cost by using an open source operating system every manufacturer can use for free. All instruments will talk with all other instruments WITHOUT this proprietary bull**** trying to force the boater to buy only our equipment we have now. Any device can connect DIRECTLY to any other device on the network. The computer can directly connect on a separate channel to the autopilot, for instance. They can swap data separately from the public broadcast channel. Ethernet - TCP/IP can make this happen this month. There's no need to reinvent the wheel with a bunch of "marine", read that "proprietary" nonsense.... My cellular provider, Alltel, is being swallowed by the most dispicable company in America, Verizon Wireless....5GB/mo for $60 + 25 cents/MEGABYTE over that limit....$250/GB! That isn't going to happen. We have a new carrier on CDMA with EVDO called Cricket. Unlimited service is really cheap in limited areas, one of which I live in. Cricket only has one model of USB cellular modem and won't permit tethering via bluetooth to my Nokia N800 Linux tablets (2), so I've looked around and found a grand solution! http://www.zatznotfunny.com/2008-02/...000-best-evdo- router-ever/ The cellular phone modem (upper left in picture grey plastic) is plugged into this magic box, which is a real router with the added feature of a USB modem port that the cellular connects to. 256 wifi users can now share the one cellular modem's limited bandwidth over regular wifi. I borrowed the router from a company here until mine is delivered and signed up for the $40/month Cricket (www.mycricket.com) EVDO cellular modem $59. Wherever I go, my car now creates a wifi hotspot I can use up to about 35 meters from the car to my Nokia N800 Linux tablets. Both tablets can be connected, simultaneously, and use the same internet connection, which on little Cricket is about 300-700Kbps on the street. It even works great underway as the car drives around because wifi doesn't handoff but cellular does. My SSID on the wifi is W4CSC/MOBILE and it's wide open....help yourself. The router is about $200 from places on the net.... This thing would be great on a boat, as the solution to the internet problem, even away from the marina with wifi. It's its own hotspot, so anywhere you'd have cellular data connectivity, you have your own wifi internet....such as anchored out in the harbor far away from the free wifi. Cellular has much wider range than any wifi to get to the boat's system. Put these things in a plastic enclosure at the top of the mast or on the yardarm and simply feed +12VDC from the house batteries permanently to it and you'll have internet wherever you have cellular. Mine simply sits on the back shelf of my '73 Mercedes 220D sedan and provides plenty of signal for sitting at a table in any restaurant, whether that restaurant has wifi or not.... I'm sure there's a similar GSM capable router that would work in Denmark and the EU available. Only the programming on the USB port interface would be different. |

They actually are concerned, your sarcasm notwithstanding, because open hotspots are frequently abused, particularly with illicit peer-to-peer filesharing. Such abuse constitutes a substantial portion of network traffic at the expense of legitimate users. Since cellular spectrum is limited, it's an even bigger problem for cellular than for Wi-Fi. Many carriers specifically address network abuse in the terms of service. -- Best regards, John Navas, publisher of Navas' Sailing & Racing in the San Francisco Bay Area http://sail.navas.us/ |

Many carriers specifically address network abuse in the terms of service. My hotspot has a blistering range of 125 feet on its best day. I doubt many peer-to-peer downloaders are within its range circle during lunch at Waffle House. I've never seen any of them connected or on its log files. You call peer-to-peer filesharing "Illicit". Which law are they breaking file sharing? Got a URL to it so I can read it? I didn't know file sharing or using bandwidth sold to me as "UNLIMITED" was illegal or immoral. If they don't want me on the system, all they have to do is shut me off and NOT TAKE MY MONEY....same as any other business. So far, noone has complained as most of the bandwidth they cannot "store" until profits rise just goes to waste, unused by anyone. I've never seen the system slow down to a crawl because users had the audacity to actually connect something to it and USE what they are paying for. The slowdowns here are caused by poor propagation and interference from large military aircraft reeking havoc with multipath flutter bouncing off large aluminum clouds. |

You might very well be surprised one of these days -- it's a big problem at local coffee houses, public libraries, etc, with open Wi-Fi. You call peer-to-peer filesharing "Illicit".

I'm guessing you haven't bothered to read your terms of service. http://www.mycricket.com/termsandconditions See #7 in particular.
