1 Copyright © 2006 – Pete Loveall AE5PL Digital Radio for the Last Mile Last 30 Miles Digital Amateur Radio vs. WiFi

2 Copyright © 2006 – Pete Loveall AE5PL Agenda Introduction Recent Disaster EmComm Digital Technology in Amateur Radio D-STAR Technology High Speed (IP) Connectivity Low Speed (Serial) Connectivity Voice EmComm Requirements Sample Scenario Summary

3 Copyright © 2006 – Pete Loveall AE5PL Recent Amateur Radio EmComm 9/11 Tsunami Hurricanes Tornados Floods Earthquakes

4 Copyright © 2006 – Pete Loveall AE5PL Why Amateur Radio? Primary Communications Infrastructure Overloaded or Destroyed Large Pool of Trained Communicators Equipment Not Reliant Upon Existing Infrastructure Frequency Agile

5 Copyright © 2006 – Pete Loveall AE5PL Primary Modes Used VOICE Winlink Packet CW

6 Copyright © 2006 – Pete Loveall AE5PL What’s Missing? Reliable, Usable Data

7 Copyright © 2006 – Pete Loveall AE5PL Is Data Important? Does FEMA Use Forms? Does the Red Cross Use Forms? Do 99.999% of Served Agencies Use Forms? Which is More Accurate: Voice or Data?

8 Copyright © 2006 – Pete Loveall AE5PL Is Voice Obsolete? No Tactical Commands Real Time Narrative Real Time Status

9 Copyright © 2006 – Pete Loveall AE5PL D-STAR Digital – Smart Technology for Amateur Radio Developed by JARL Open Protocol Specification Digital Voice Digital Data

10 Copyright © 2006 – Pete Loveall AE5PL D-STAR High Speed Data 1.2 GHz 128 Kbps (150 KHz BW) IP Ethernet Connection Internet Capable

12 Copyright © 2006 – Pete Loveall AE5PL D-STAR vs. WiFi 128 Kbps 15-20 Mile Range Omni-directional Antennas for Range 10 Mbps 1-2 Mile Range Directional Antennas for Extended Range

13 Copyright © 2006 – Pete Loveall AE5PL D-STAR Voice/LS Data 144 MHz, 440 MHz, 1.2 GHz 4800 bps (6 KHz BW) 3600 bps AMBE Voice (EC) 1200 bps Data 3 Wire RS-232 or USB 1.0 GPS Capable

14 Copyright © 2006 – Pete Loveall AE5PL Digital Voice/Low Speed Data

15 Copyright © 2006 – Pete Loveall AE5PL DV vs. AV Combined Voice/Data 6 KHz Bandwidth Error Correction Greater Range Voice & Data on Separate Channels 12 KHz Bandwidth Weak Signal Noise

16 Copyright © 2006 – Pete Loveall AE5PL D-STAR Applications D-PRS –Icom GPS & APRS Remote Internet Simultaneous Voice & Data Simultaneous Voice & GPS Data

17 Copyright © 2006 – Pete Loveall AE5PL EmComm Requirements Rapid Deployment Minimal Learning Curve Remote Connectivity Minimal Infrastructure High Accuracy Immediate Response

18 Copyright © 2006 – Pete Loveall AE5PL Sample Scenario Katrina Aftermath –Infrastructure Destroyed or Ineffective –Command and Control Destroyed or Significantly Reduced –SAR Efforts Required –Shelters Deployed Throughout –Logistical Support Required

19 Copyright © 2006 – Pete Loveall AE5PL Primary Communications (Non-Amateur Radio) Satellite Voice Satellite IP Direct VHF/UHF Agency Communications

20 Copyright © 2006 – Pete Loveall AE5PL Amateur Radio Requirements Rapid Deployment Trained Communicators Radios Compatible with Temporary Infrastructure Large Area Coverage Voice/Data/IP

21 Copyright © 2006 – Pete Loveall AE5PL Amateur Radio Requirements Rapid Deployment –D-STAR Go Kits Trained Communicators –Amateur Radio Operators Radios Compatible with Temporary Infrastructure –D-STAR High Speed Connectivity with Satellite –D-STAR Low Speed Connectivity (including Voice) with Satellite Large Area Coverage –10-30 Mile Radius Voice/Data/IP –D-STAR DV on single channel –D-STAR High Speed IP
