4 ITS equipment e connected via Wireless ess Electronic message signs Variable speed limit systems Remote weather information stations (RWIS) Highway Advisory Radio (HAR) and connected sign beacons License plate readers Traffic detection (radar, etc) Cameras full motion PTZ and snap shot 4

5 Why Wireless Data? Lower cost per mile as compared to fiber in rural areas IP standards have increased competition and decreased equipment costs by almost 50% in the last 10 years. Potential wide area of coverage Higher reliability than commercial services (DSL and copper) Lack of acceptable commercial services in rural areas. Potentially less expensive over time compared to leased services particularly cell Not a replacement for fiber 5

6 New approaches Backhaul Capacityneeds to matchthe the need: WSDOT s wireless backbone is up 155MBs IP based connectivity o Serial to Ethernet converters for legacy devices Connectivity Point to Point & Point to Multipoint Medium speed wide area coverage Licensed or Unlicensed 4.9 GHz, new licensed spectrum for public safety. Can be deployed for up to one year before a license is required. 6

7 Connectivity ty - Point to point Backhaul Backbone or dedicated local short haul Licensed Longer distanced up to 50 miles Fixed Higher Capacity up to 155 MBs Lower cost per mile compared to fiber for rural areas Requires Line of sight IP based 7

8 Connectivity: Point to Point & Point to Multipoint i t Licensed or Unlicensed Distances up to 30 miles Capacity up to 24MBs Longer the distance the lower the bandwidth IP based Line of sight or near line of sight All ITS devices including full motion PTZ 8

9 Connectivity: ty Wide Area Coverage Licensed Distances up to 50 miles Lower bandwidth up to 64KBs Bandwidth is fixed 64KB or 32KB One base can handle several ITS devices IP based Non Line of sight All ITS devices except full motion PTZ Support mobile applications 9

10 Connectivity - Wide Area Wide area coverage from a selected site. WSDOT Gabi, Burch and Goat Mt communication sites provide over 6000 square miles of coverage. 10

11 Connectivity - Wide Area Near line of site at 49 miles. 11

12 Connectivity ty - Wide Area Near line of site at 49 miles. RWIS, SignControl and Snap ShotCamera 12

13 Connectivity ty - Wide Area Non Line of sight Sign Control 13

14 Licensed or Unlicensed Licensed 6Ghz, 11GHz, 18GHz and 23GHz up to 155MBs o Advantages no interference o Disadvantages higher costs 4.9 GHz up to 24MBs o Advantages no interference, lower costs o Disadvantages limited bandwidth Unlicensed 900Mhz, 2GHz and 5.8GHz up to 24MBs o Advantages deploy quickly, low cost o Disadvantages possible interference in urban areas o Risk of future interference 14

15 Challenges Bandwidth dt and Location o Wireless can be bandwidth limited Use higher capacity equipment to connect hubs or sites together and to get back to the Traffic Management Center Use Point to Point and Multipoint systems to connect to Devices that need bandwidths over 64KBs (PTZ Cameras) Use Wide area systems to connect more devices over a greater distance or where you do not have line of site or only need moderate bandwidth Plan accordingly know your backhaul capability Location Take into consideration your wireless connection when locating an ITS Device Line of site provides the best reliability for Point to Point and Multipoint systems Do you anticipate mobile data needs in your future? 15

16 Challenges Equipment and Costs Equipment Type Licensed Unlicensed Costs High capacity, High reliable microwave backhaul $50K to $60K per end Lower capacity, Point to Point and Multipoint $2K to $4K per end Wide area 64Kbs $20k per repeater or site and $2.5k per radio at an ITS location 16

17 Challenges Standards ds and Product Life Cycle Standardization and Product Life Cycle Microwave backhaul and Wide area equipment ttypically have a longer product life cycle 15 to 20 years. o Easier to standardize on equipment Point to point and Multipoint systems have shorter life cycles. They tend to follow a PC (consumer electronics) type trend. o Challenging to standardize on equipment and sometimes a vendor 17
