1. Wireless Communications in ITS

2.  Existing Applications  Interconnect  Remote Communications to Field  Original Future Concept  Plans Can Change

3.  164 th St SE & 3 rd Ave SE to 164 th St SE & 9 th Ave SE  Connects Mill Creek with Snohomish County ENCOM 5200 ( RS-232) 900 MHz

5.  Notebook Computer  Wireless Air Card (Cellular Modem)  Connect to System  Connect to Signal/PTZ/Video Detection

6. Wireless TMC

7.  Dial up Telephone  To field masters  To isolated. Stand alone signals  Very slow  Lots of lines and lots of modems  Expensive  DSL/Cable  Faster  Still expensive

8.  Fiber Optics not Considered an Option.  Broad geographic region  Lack of available fiber  Complicated and expensive  Total Wireless System was the Idea  Arterial mesh network (point to multi point)  High capacity backhaul system (point to point)

11. Wireless Arterial Mesh Network

13. Minimum Radio Requirements  5.8 or 5.9 GHz  50 Mb minimum bandwidth for intersections.  300 Mb minimum bandwidth for backhaul

14. Installation Requirements  Multiple Routes  Good Line of Sight  Turn Key Operation  Be Flexible

15.  Enter Black Rock Cable (Fiber Network)  Connections to Major Corridors  Pull 12 Strand Fiber and Splice to Signal  Black Rock Needs to get to SR 9  Snohomish County Conduit Banked to SR 9

16.  Enter County DIS  Purchase of Dark Fiber from Black Rock  Eventual Multiple Path Fiber Connections to all signals
