900 MHz: for urban & special rural overlay. Wireless Wide Area Networks (WWANs).
200 MHz: for rural & redundant urban underlay. WWANs: mostly in dual-mode with the 900 MHz.
Public / nonprofit / private joint ventures for ITS.
Telesaurus - University California ITS research: Telesaurus has a multi-year contract with UC (Berkeley) to provide collaborative R&D for its ITS program: in sum, nationwide ITS wide-area wireless, including integration with ITS local-area DSRC, and terrestrial pseudolite augmentation of GPS for US ITS and PNT, with initial test systems planned in California.
(See also diagram and other pages on this site for details.)
Multi- band vehicle installed radios: 900 & 200 MHz for WWAN; 4.9 GHz, 5.9 GHz DSRC, 2.4 & 5.8 GHz for mobile (in-vehicle) & roadside WLAN. WWANs handoff to roadside WLANs where there is secure coverage, increasingly available (offload traffic from WWANs to less expensive WLANs).
WWANs optimized for vehicular coverage. Vehicle power and antenna platform used. Software radio based. MIMO used as implemented in underlying standard-based equipment. COTS based.
IP based, with some circuit / PSTN. Some MSS satellite augmentation and backup.
Mobile high-speed broadcast (datacast) (digital, ODFM, ISDB-Tn/TDS-OFDM tech based) for: (1) core ITS data (regularly updated information, with high granularity, of: weather, road conditions, emergency alerts (preemption by, transit and transport schedules, critical roadside facilities (see “ISDB-Tn+caching” on ITS page), (2) terrestrial multilateration enhancement of GPS/GNSS (and backup of GPS if GPS jammed or spoofed) for core ITS constant vehicle location determination (by the mobile units), (3) broader location-based applications.
Two-way high-speed data (digital, standards-based, mission-critical tech based) for: (1) certain interaction with broadcast system, (2) return of location fixes, (3) emergency real-time voice and data communications, (4) other two-way communications secondary to core-ITS and emergency primary. See TETRA links on next page.
Agency preemption in emergencies of large capacity on the broadcast and two-way: shift capacity from non-emergency to emergency. The non-emergency use build “battery” for emergency use. Cache of extra enduser radios in several air-hub locations in US to fly in for emergencies.
Same system provides wireless links to fixed-stations for ITS data monitoring along highways, and key environmental data throughout ecosystems, with mesh-net coverage extension.
Construction and operation leveraging existing two-way and broadcast radio infrastructure of partner agencies and infrastructure companies, who are also core end users with secure capacity, access, etc.
Extensions to private maritime and private aircraft services, and inter-modal asset tracking.
Nonprofit foundation assisted, including access to spectrum, through all phases.
Designed to increase qualification for current and future federal support, due to high-public interest objectives, efficiencies, and long-term approach.

1. Congestion Mitigation. The below is from the US DOT ITS Office (underlining added):

“ Crisis of Congestion. Traffic congestion affects virtually every aspect of peoples’ lives – where people live, work, shop, and how much they pay for goods and services. According to 2003 figures, in certain metropolitan areas the average rush hour driver loses as many as 93 hours per year to travel delay – the equivalent of more than two weeks of work, amounting annually to a virtual “congestion tax” as high as $1,598 per traveler in wasted time and fuel. Nationwide, congestion imposes costs on the economy of over $65 billion per year, a figure that has more than doubled since 1993, and that would be even higher if it accounted for the significant cost of unreliability to drivers and businesses, the environmental impacts of idle-related auto emissions, or increased gasoline prices.

“ Traffic congestion also has a substantial negative impact upon the quality of life of many American families. In a 2005 survey, for example, 52 percent of Northern Virginia commuters reported that their travel times to work had increased in the past year, leading 70 percent of working parents to report having insufficient time to spend with their children and 63 percent of respondents to report having insufficient time to spend with their spouses. Nationally, in a 2005 survey conducted by the National League of Cities, 35 percent of U.S. citizens reported traffic congestion as the most deteriorated living condition in their city over the past five years; 85 percent responded that traffic congestion was as bad or worse than the previous year. Similarly, in a 2001 survey conducted by the U.S. Conference of Mayors, 79 percent of Americans from ten metropolitan areas reported that congestion has worsened over the past five years; 50 percent believe it has become “much worse.” “

2. Saving Lives, Reducing Accidents, Reducing Pollution, Improving Travel, etc.. Also from US DOT: ITS Benefits by category. ITS is absolutely essential to mitigate the congestion crisis described above as discussed in fundamental ITS documents in the last decade. ITS also is required to provide solutions to a host of other critical public-safety and public-interest problems. These problems and ITS solutions are described by category in the preceding DOT link, and also in FCC proceedings that established the two ITS Radio Services: LMS-M for wide area ITS wireless, and LMS-N and DSRC for short range ITS communications.

3. Nationwide ITS Wireless as Foundation for State & Local Government Wireless. Telesaurus has proposed this for years, and principals involved (while fairly obvious) are supported in various public and private studies by economists. It makes eminent economic and operational sense. The US DOT has stated that it may mandate DRSC (short range ITS wireless) before long in new vehicles, and plans a nationwide DSRC network: at main intersections and interchanges, and some other locations. If wide-area ITS is combined with DSRC as Telesaurus is pursuing, described throughout this website, such ITS wireless systems can provide an excellent, stable, mission-critical grade foundation--i.e., the wireless infrastructure, technology base, backhaul and other links, and coverage-- on which new regional governmental wireless can be developed and operated very cost effectively. In addition, local and state governmental entities is already substantially involved in ITS for the broadest ITS goals regarding all users of highways and other transportation systems. This “foundation” plan would benefit those entities as well as core “public safety” entities (law enforcement, fire, emergency medical, first responders, etc.) and all other government agencies that use wide-area wireless. For example, public safety 700 MHz and 4.9 GHz systems could be “hung onto” the ITS systems. In addition, ITS systems can provide “turn around” wireless capacity for such government agencies to restructure their VHF and UHF spectrum and systems: the agencies can use for some months to several years the ITS systems for some of their needs, allowing them to restructuring the highly fragmented and inefficient licensing in these bands among governmental entities. (Since these bands are fully used now, with minor exceptions, to restructure them requires relieving some of the current intense usage, as just proposed.) Also, public agency, including core public safety, entities will be major users of ITS wireless (each having large vehicle fleets and mobile workforces), and their own private wireless systems should be well integrated with their use of the ITS systems, including for much improved response to emergencies and other situations along roadways and other transportation systems.
