All rights reserved Why Is Wireless Data Delivery to cars so Important?  When you are in your car, you are going places.  How do I get there?  What is the traffic like ?  Where can I eat, drink or be merry?  Is there room at the inn?  What is the next available tee time?

6. Copyright 2004 Tele Atlas. All rights reserved Cell Network  Infrastructure Cost (already exists)  ~200K/tower X 300 towers per major market = $60M/major market + license fees  Benefits  Two-way communication  reasonable bandwidth  Good coverage in major markets  Issues  Not always on (yet)  Data services compete with very profitable voice bandwidth

7. Copyright 2004 Tele Atlas. All rights reserved 802.11 Wireless Internet Network  Infrastructure Cost  ~5K/base station X 1,000 base stations = $5M/major market  Benefits  Two-way communication  Great bandwidth potential  COTS hardware  Issues  No alternate revenue stream to subsidize buildout yet… (Gov’t funding of VII or other commercial apps)  Need power and right of way to install network  Time – Not a short term alternative until infrastructure built out

8. Copyright 2004 Tele Atlas. All rights reserved Satellite Radio  Infrastructure Cost (already exists)  ~200M per launch + 100M per satellite + Ground Repeaters = >$1B for nationwide coverage  Benefits  Nationwide coverage  Issues  National broadcast requirements makes local data expensive  Receivers currently expensive  Current economic drivers are the number of subscribers, not value added data services. Adding the “Marching Band Channel” might drive more subscribers than a new data service.

9. Copyright 2004 Tele Atlas. All rights reserved Terrestrial Radio  Infrastructure Cost (already exists)  ~500,000K/transmitter X 5 transmitters = $2.5M/major market  Benefits  Local broadcast of local data  Uses sidebands and does not take away from core audio bandwidth  Upgradeable to Digital for increased bandwidth  Issues  Billing mechanisms more difficult  Coverage spotty outside of Urban Areas

All rights reserved Wireless Data to the Car - Conclusions  Satellite Radio appropriate for one-way low- bandwidth national content  Terrestrial Analog Radio efficient for one-way local content  Terrestrial Digital Radio effective for large amounts of one-way local or national content (like POI or map updates)  Cell Phones a good bridge solution for 2-way communications, until…  Wireless Internet is a great solution when infrastructure implemented.
