Grayson Wireless selects Trimble's GPS receivers for wireless 911 location systems - Business - Brief Article

Mobile Internet, The, April, 2002

Trimble announced that Grayson Wireless has selected its GPS time and frequency receivers for installation in Grayson's Geometrix wireless 911 caller location systems. As a part of the Geometrix system, Trimble's OPS receivers will provide precise timing synchronization between Geometrix base station location receivers to locate an emergency caller's handset.

Grayson's network-based Geometrix Wireless Location Systems are compatible with all cellular and PCS network technologies, and all existing customer handsets. Grayson builds and installs Geometrix systems for wireless carriers to comply with the FCC Phase II E9 11 regulations for wireless 911 caller location. The system automatically determines and forwards a wireless caller's location coordinates to public safety agencies that receive emergency calls. To maintain caller privacy, Geometrix systems are designed to provide location information only when a wireless user initiates a 911 call.
