Wi-Fi Hack Aids Boarding Parties 69

Posted by Zonk from the guess-where-i'm-iming-from dept.
Kage-Yojimbo writes with a link to the site Strategy Page. There, they're reporting on a military adaptation of civilian wi-fi equipment to use in boarding operations on the high seas. Modifications to normal off-the-shelf gear can result in a range of over 700 meters, allowing information to be passed through on-shore internet connections. "The main reason for all this was to speed up the transmission of passport photos and other personal data back to the ship, so that it could be run through databases to check for terrorists or criminals. This wi-fi hack cut several hours off the time required to check documents. The Expanded Maritime Interception Operations (EIMO) wireless system was developed last year, to provide several kilometers of range to the original wi-fi gear (which has been in use for over three years). Each pair of wi-fi units costs about $1400 to construct, using common parts to add more powerful antennae to standard 802.11g wi-fi equipment."

      Or basic WISP equipment. Tranzeo has 4.9ghz systems that start at $433 per radio, and can do a good 5 miles or so. Each unit can act as a client, a bridge, or an AP (they sell directional units, and units with n-connectors so you can attach a direction or omni antenna) Ive installed their 2.4ghz radios as far as 5 miles from an AP. $1400 bucks for a pair of radios seems a bit much, IMO. Not that the article was heavy on details anyway.

      • Equipment brands aside- It's not so much the cost of the radio as the cost of the antenna.

        Per FCC regs, a Point-to-Point connection can have an 'unlimited' power output - that is to say, following the outlined methods of reducing the intentional radiation before the antenna - you are only limited by the radio's ability to scale its signal down, the passive gain and quality of your antenna's element, and the attentuation of the connecting hardware between the radio and the antenna (cabling, connectors, etc).

        Not entirely true. The FCC also allows you to increase EIRP up to 4W if your antenna gain is at least 6dBi and the system is a fixed, point-to-point setup (Part 15.247). You must also reduce your transmit power 1dB for every 3dB of antenna gain over 6dBi, which means you can technically achieve much higher than 4W EIRP if you've got a ver

        • Whether a ship anchored offshore qualifies as "fixed" or not, well I'm not sure.


          A tricky one, for sure. Oftentimes fixed is regarded as Point-to-Point, while mobile Point-to-MultiPoint.

          The 4W EIRP is for PtMP - PtP/Fixed is only limited by the decrease active gain/increase passive gain rule and the fact that there comes a point when you can't reduce the wattage of the radio without attentuating before the antenna element.

          The military has their own frequencies which they can use for (relatively) unencumbered communications. When they use the ISM bands used by 802.11, they are bound to the same limits as the rest of us (legally).

    The military has much higher requirements for equipment. It wasn't until just recently that 'throw away' equipment became good enough for military use. By that I mean that the cost of replacement / repair became equivalent or parity. A cantenna and a $70 router can be replaced quickly without need for repairs... that is to say that the repair process is called replacement. This was never the case for military grade equipment in the past.

    The advent of surface mount parts caused the cost of manufacture to drastically drop while the cost of repair soared. This doesn't work for armored vehicles, but for electronics it does.

    You will notice other effects of 'modern warfare' also: the humble low-tech RPG has been a fiercely dangerous weapon. Very low-tech roadside bombs are rising in popularity too. While that has little to do with the cantenna and COTS 802.11g router, it does show that high dollar, high tech equipment is not always the best choice. If it works, well.. it works, and if people in the field find something that works, you will have trouble stopping them from using it.

    I'm sure that the Pringles company are more than willing to keep shipping chips to the middle east.

      Not so. The military has long found that it is sometimes more efficient to simply discard malfunctioning equipment. Remember, cost is not so much an issue as availability. A radio that's out for repairs is unavailable, and the cost of that unavailability can be higher than the price tag of a brand new unit. Trained service technicians are not always on hand either, particularly under battlefield conditions.

      My father was in the military a long time ago, and the techs he know would often just tag a piece of electronic equipment as "unrepairable" when the only thing wrong was something like a busted knob. That's because new equipment was readily available, tech time was expensive and limited and it just wasn't worth their time to try and fix it. They had more important things to do.
      • There are stories dating back to World War II when New Zealand aircraft mechanics would trawl the junk piles at American air bases in the Pacific to salvage parts that were judged "unrepairable" by US forces. With a bit of time and effort, the part would be made servicable again and deployed on a NZ aircraft.

    The U.S. Navy has adapted civilian wi-fi (wireless networks) for use at sea during boarding operations. By modifying off-the-shelf wi-fi gear, the navy increased the range to over 700 meters. The main reason for all this was to speed up the transmission of passport photos and other personal data back to the ship, so that it could be run through databases to check for terrorists or criminals.
