Hi capstone,
This sounds similar to a product demonstration National Instruments did, tracking cyclists live on Google Maps.
Check it out!In
this case a PDA was used (as Mike suggested) for acquiring data
(including GPS), which was then sent to a remote server via a mobile
broadband modem. The server then updated Google Maps.
The modem used
was not a National Instruments product. The only Wi-Fi product we
currently provide is the NI WAP-37x1 industrial wireless access point,
client, and bridge. It is basically an industrial version of a common
802.11b/g wireless router. This makes it useless for a communication
range of an entire city, but could suffice to give a smaller scale
demonstration.
