3. Cohda Enhanced DSRC Radios
• Cohda has developed a DSRC Radio from the
ground up
– Unmatched outdoor, mobile performance
– We do not simply use WiFi chipsets
• Proven in over 11,000 kms of field trials
• Increasing OEM buy-in
– Our radios selected for large European FOT

4. VII PoC Key Findings
• COMM-2: Range for V2V between low height vehicles
is not adequate
• COMM-5: Antenna height from the ground has
significant impact on range
• COMM-6: Antenna pattern and orientation has a
significant impact on range
• COMM-9: DSRC range is heavily dependent on line of
sight; terrain effects are thus line of sight limited.

5. Intersection Collision Warning A
• Severely impaired performance of the COTS
radio for 400 and 2000 byte packets; and
• Cohda 30-40% better range than COTS for short
Rx
packets.
Tx
0 kmph 60 kmph

6. Intersection Collision Warning C
• Severely impaired performance of the COTS
radio for 400 and 2000 byte packets; and
Rx • Cohda 60% better range than COTS for short
0 kmph
packets.
Tx
60 kmph

7. Turn Across Path A
Tx
100 kmph • Severely impaired performance of the COTS
radio for all packet lengths; and
Rx & Truck • Cohda has more than 60% better range than
0 kmph
COTS for all packets.

8. Turn Across Path C
• Severely impaired performance of the COTS
radio for all packet lengths; and
Tx Rx & Truck • Cohda has more than 25% better range than
60 kmph 0 kmph
COTS for 50 byte packets, and COTS is
completely ineffective for longer packets.

9. Do Not Pass Warning A
• Severely impaired performance of the COTS
radio for all packet lengths; and
Rx & Truck
Tx
90 kmph • Cohda has more than 120% better range
90 kmph
than COTS for all packets.

10. Do Not Pass Warning D
• Severely impaired performance of the COTS
radio for 400 and 2000 byte packets; and
Rx & Lead
Tx 60 kmph • Cohda has more than 50% better range than
60 kmph COTS for short packets.
