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

ATP
MPS (Mesh Positioning System)
Works Indoors & outdoors
 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

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
