What Makes MEA Better?
Adhoc Peer to Peer
(N:N)
Infrastructure
(1:N)
adhoc Peer to Peer Multi-Hopping®
Cost-effective performance, scalability &
survivability with seamless support
for ad hoc and infrastructure-based operation
Ad Hoc Mode
Client to Client communications
Clients can hop thru each other to reach other clients in the
network
Infrastructure Mode
Client link directly to Wireless Routers or Intelligent Access
Points
Unique solution that supports both Simultaneously!
“adhoc Peer to Peer Multi-Hopping®”
Increases coverage & reliability while increasing system-wide
performance
The Origin of MEA
DARPA Requirements:
• 250 Mph mobility
• Megabit data rates
• 100% IP based
• No fixed infrastructure
• Highly survivable
• Accurate/fast Position -location
• Resistant to interference
Ideally suited for demanding
mobile broadband users

• Multiple data channels defined by frequency for high spectral efficiency
TDMA / TDD
• Sequenced message data for minimal contention and channel utilization
efficiency
CDMA / DSSS
• Spread spectrum for excellent processing gain and multiple code defined
channels for high spectral efficiency
CSMA / VCS/MA
• Virtual carrier sense similar to wired Ethernet

Non GPS based
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

MEA System Overview
Basic Technology
Mesh Networking
ad hoc peer to peer multi-hopping
RF Modulation : QDMATM
Frequency : 2.4GHz, 2nd ISM Band, Non Licensed Frequency
Frequency Channel
3 x 20 MHz for Data
1 x 20 MHz for control
Data Rate
Burst : 6 Mbps / Throughput : 1.6 Mbps
Handoff : Soft Handoff (Make-before-Break, Cellular Type)
Mobility Speed : 250 mph (= 400Km/h)
Output Power : ~ 300 mW ( ~ 25dBm)
Antenna Gain : 1, 2, 4, 8 dBi
Geo-Location : DTOF (Differential Time of Flight), Non-GPS System

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
Eddie Cheevers Race Team
WiFi was tried and failed,
but MEA still used today
Racing Video
- 400 miles at 230mph
- 100% coverage over track
- 1000 measurements per sec.
- 700 seamless handoffs per race
* 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

Reliability & Coverage Extension
Reliability
Peer to Peer Multi-hopping will reduce shadow area and make the service stabilized
Coverage Extension
2.4GHz, 5GHz ISM have less coverage by
limited power and antenna gain
Client outside of coverage can connect to
the network by multi-hopping
