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
