Wireless Mesh Bear Tracking

Project Plan

GPS Unit on bear collars

Collar transmits GPS location via VHF frequency to land-based routing units

Routing units relay collar location information to a remote end user

Implementation/Testing

Phone conference with Digitwice.

PCB/Layout All schematics and

layout have been completed.

Layout sent forfabrication on February 15th, received February 24th.

Will be making 2 units
