See preceding page for ITS and IRF wireless.
 
ATLIS associates hold FCC licenses in 217-222 MHz, 904-910 MHz, and near 930, 940, and 960 MHz in over 80% of the US including all but a small percentage of the major markets for ITS and related IRF networks.
 
The best way to build and support these includes access to the best wireless technology, and partnering with both US critical infrastructure and State, local, and Federal public agencies to partner in building and operating networks with substantial shared components (with suitable security, firewalls, etc.).  
 
We are working on an number of initiatives to achieve this, including:
  1. •   The TETRA-US Initiative.  See www.tetra-us.us, a website sponsored by the ATLIS-related nonprofit foundation, Skybridge Spectrum Foundation (“SSF”).  
  2. •   TETRA and other needed equipment to work on 150-222 MHz and 700-900 MHz (all private and governmental PMR bands in these two broad ranges).
 
The more we can assist US public agencies and critical infrastructure obtain or at least have access to advanced equipment and have solutions in these ranges, the more we will have opportunities to partner for the above-noted public-private partnerships involving ITS and IRF.  
 
Regarding these two bands, especially 150-222 MHz: solutions we are working on, and that can be achieved soon, include:
  1. •   TETRA equipment: see here >>>>>.
  2. •   SDR for ITS, in our research contract with University of California CCIT (generally described in the two downloadable papers at top of this page:  >>>>>, and in the SDR Forum (SSF is a member): see the Forum’s site under ITS matters: >>>>>.
  3. •   Use of our “geographic” 217-222 MHz as “turn around” spectrum in networks deployment partnerships with US public agencies (such as statewide wireless programs) and critical infrastructure (such as regional power utilities), where, with TETRA equipment spanning 150-222 MHz, they shift traffic to 217-222 MHz, then reorganize their site-based VHF high band spectrum into a better regional plan, then put the VHF band into service.  (The same may be achieved in 800-900 MHz, but the need appears greatest in VHF high band.)
  4. •   Use of SDR and multi-mode PMR chipsets such as the “Superstar” chipset, to enable the equipment for the above purpose to operate both on TETRA mode (25 kHz wide channels with 4-slot TDMA) and P25 mode (12.5 kHz wide channel FDMA).
