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."
