Existing System Communications
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

Original Future Concept
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)

Original Future Concept
Minimum Radio Requirements
5.8 or 5.9 GHz 50 Mb minimum bandwidth for
intersections.
300 Mb minimum bandwidth for backhaul
![Page 14: Wireless Communications in ITS. Existing Applications Interconnect Remote Communications to Field Original Future Concept Plans Can Change](https://reader031.vdocuments.site/reader031/viewer/2022032201/56649d2e5503460f94a04cf8/html5/thumbnails/14.jpg)
Original Future Concept
Installation Requirements
Multiple Routes
Good Line of Sight
Turn Key Operation
Be Flexible

Plans Change
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

Plans Change Again
Enter County DIS
Purchase of Dark Fiber from Black Rock
Eventual Multiple Path Fiber Connections to all signals
