One of my old college buddies worked on a system like this, years ago now, in the Toronto area. Their biggest recurring issue was with the vehicle maintenance manuals, which typically would begin each procedure with an instruction to the mechanic to disconnect "all electronic devices" and end with an itemized list of devices to be reconnected -- the latter of course not including the recently-added GPS unit....

On our end, we found that the bus provider wasn't real interested, and then they ended up doing it themselves. Go figure. What about leveraging the USB port on the modem, for the likes of the USGLOBALSAT or Garmin GPS that connect via USB? I don't know that it could be done, but it's another interface to consider. -Lee From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Zachary McGibbon, Mr Sent: Wednesday, February 01, 2012 11:28 AM To: [email protected] Subject: [WIRELESS-LAN] Inter-Campus Wifi & GPS Tracking Last year there was some discussion on this list as per setting up Wifi on Inter-Campus shuttle buses and here at McGill we were in the middle of doing our tests for our 4 shuttle buses between our downtown and remote campus. As of January this year, we now have Wifi on all four of the buses. We are using a setup of: . Aruba AP70 . Bluetree BT-6801EB Modem (3G) . Axis T8122 DC 30W Midspan (to power the AP) . Oberon 1025-00 NMEA enclosure We chose the Axis POE injector since the Aruba AP only has a 5v input and we are running directly off the alternator of the bus which gives us 12vdc. One of the next parts of the project we would like to do is to add GPS tracking to the bus so students would know how close the bus is (as it gets quite cold here in Montreal during the winter!). Since there is a second Ethernet port available on the AP70, we thought of using this for the GPS, however I can't find any Ethernet GPS'. Does anyone have any ideas of what we could use? I had thought about getting a Garmin OEM GPS with a serial port output connected to a Lantronix Serial to Ethernet box and sending back the NMEA strings to a server, however I wanted to find an all included Ethernet solution and not have to worry about powering and configuring two devices. Also, if we did use the OEM solution with NMEA strings, I'd have to find some way of plotting these on a map (Google Maps would be preferable) and this would probably require a lot of in house programming, or of course we could just use APRS.
