Supports 3 Tracking Modes Absolute
• References from network infrastructure
Pre-deployed network
Outputs GPS coordinates
Relative• References portable routers
• Gives position within area
Proximity• Shows distance to reference nodes
* GEO Location
Differential Time of Arrival (DTOA)
Requires minimum of 3 Infrastructure Neighbors (1 hop) Infrastructure nodes must have GEO location programmed in them
Must have better than -75 dB link to neighbors
Will use up to 6 nodes in the calculation
Geometry is important for accurate geo (prefer reference nodes on a plane
rather than a line)
Requires good geo coordinates programmed into devices At least 6 digit accuracy
Deploying GEO will require a greater number of infrastructure devices
and enough consideration

Real Time Data Analysis Proven always-on mobile connectivity 100% coverage 230+ MPH
Seamless Performance in Incredibly Harsh Environment Heat, Vibration, Interference Overcame the ‘Wall of RF Noise
WiFi was tried and failed, but MEA still used today
Eddie Cheevers Race Team- 400 miles at 230mph - 100% coverage over track- 1000 measurements per sec.- 700 seamless handoffs per race
Racing Video
* High Speed motion
Key Points Vehicular Mobility = Motion and Hand-off tested at 230mph race track trial High speed motion with real-time handoff is required for data connectivity at vehicular
speeds. Real time handoff enables future applications such as Voice over IP and real time
mobile video. Data rate drops as speed increases
Feature Benefits Always up data connection – even when moving videotape traffic violations for DUI/stolen vehicle evidence
Competitive Data Points There are none Some competitors “claim” motion at 2.4 – but competitors claim a lot and deliver little 802.11a does not support motion; 802.11b/g will support up to 30mph with limited
data rates per internal testing
