Intelligent transportation systems (“ITS”) is vital for safety and efficiency on the nation’s roadways, and similar benefits in other forms of transport: maritime, air, and rail.  ITS is being vigorously developed worldwide and ITS-specific wireless is essential for dozens of major ITS applications.  These matters are described in one of ATLIS affiliate’s websites, www.telesaurus.com and in many other sites listed on its ITS links page. This involves more complex and advanced forms of wireless than current commercial and private mobile radio, including sub-meter level accuracy vehicle location with high reliability and consistent coverage in major metropolitan areas and eventually along most well-used roads and transportation facilities and corridors.
 
ITS, based on vehicle radios and coverage, is a perfect platform for Software Defined Radio (“SDR”).  SDR and ITS wireless will provide means for Intelligent Radio Frequency (“IRF”).  Precise location of vehicles and their RF antennas, and SRD will facilitate and utilize cognitive radio (“CR”) more fully than is possible for some time beyond in small handheld devices, due to the vehicles having the power, weight, and sized needed for cost-effective high-performance SDR based radio communications and GPS-terrestrial radiolocation reception and determinations.  
 
The above-described systems will utilize mission-critical grade radio for (this is a summary list):
  1. (1)  Very high accuracy terrestrial+GPS location.
  2. (2)  Two-way data to carry the location and instructions between vehicles and the ITS and IRF systems, emergency    
    communications (data and voice), and other essential transport data.
  3. (3)  Broadcast data to update onboard databases of all essential transport and safety information.
  4. (4)  Some additional more general two-way information on lower-priority basis.  
  5. (5)  Integration with 5.9 GHz ITS DSRC, and support of 4.9 GHz public safety local systems.
  6. (6)  Cross-band vehicle repeaters, for some classes of users, including the Infrastructure partners described below.
 
ITS SDR IRF will, in turn, support extensions of the network for wireless environmental monitoring and protection of essential components in the natural ecosystems, and essential components of the major human physical systems or “critical infrastructure” including power production and distribution systems.  These will mostly be fixed-data network extensions and applications.
 
ATLIS and its affiliates seek to partner with US Critical Infrastructure and governmental entities to deploy and provide essential wireless infrastructure for these planned ITS IRF systems, as described in the next two pages.
