slight correction - GeoComm developed a piece of software that can integrate the cellular location into an E911 network. The actual angle of arrival location derrivation hardware was built and patented by KSI Inc. out of Annandale VA (www.ksix.com). Our successful E911 integration was accomplished by a consortium of companies: KSI, Rural Cellular Corporation (RCC), CML Technologies Inc., Datamaster, and GeoComm. KSI reports that vehicle tracking is a possible use for this technology, but this is not anything GeoComm developed or offers. Anyone interested in this new technology should check out KSI's web site. Also, while the new technology could reduce the cost of a tracking device to whatever your cell phone costs, the location derrivation network must already be in place - so there is still a high cost. This could work in the future if it becomes standard for cell sites to be equipped with this type of gear. GeoComm currently offers vehicle tracking hardware that can interface to conventional or trunked VHF or UHF radio networks. We also have a unit that can connect to a cellular or PCS phone.

However, GeoComm has just developed new technology that can locate cell phones without GPS. The new system involves setting up directional equipemnt on cell towers which can monitor a wireless phone's service channel and report its location as often as desired. He reports that the prototype system is accurate to 50 ft, and can work where GPS can't (like in buildings). It elimintates the cost barrier because the cell phone doesn't have to make a call to report locations; it just has to be turned on. ---------------------------------------------------------------------- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
