fcc 800 mhz rebanding project

"800 MHz Rebanding" refers to a requirement by the Federal Communications Commission (FCC) to reconfigure certain frequencies in the 800 MHz band to eliminate interference between commercial systems and public safety or industrial system. If your agency is currently licensed on any affected 800 MHz frequencies, you should have received notification from the 800 MHz Transition Administrator (www.800ta.org) concerning the rebanding of your 800 MHz frequencies system.

If affected, your agency should be in the process of negotiations with Sprint for a Planning Funding Agreement (PFA) that provides funds to plan for your reconfiguration. The PFA will ultimately lead to a Frequency Reconfiguration Agreement (FRA), which provides reimbursement to your organization for the required costs associated with the physical reconfiguration of your systems.

The Arizona Interagency Radio System (AIRS) uses national interoperability channels in the 800 MHz band that ARE affected by rebanding and must be reconfigured. The Arizona Department of Public Safety, Wireless Systems Bureau has completed negotiations with Sprint to fund the planning phase of rebanding for these channels and will soon begin the efforts needed to develop a reconfiguration strategy for AIRS.

At this time, we anticipate following a phased migration approach of 800 MHz channels at AIRS sites on a published schedule. We understand that many agencies rely on these AIRS 800 MHz channels for interoperability and that reconfiguration of agency user radios may be required before an AIRS site can be reconfigured. A schedule for reconfiguration of the AIRS 800 MHZ channels including these dependencies will be published on this site as it becomes available.

If you are not directly licensed for the AIRS 800 MHz channels but are utilizing them under a memorandum of understanding with the State of Arizona licenses (AIRS MOU), your user radio reconfigurations may be included as part of the State of Arizona 800 MHz Rebanding Project.

During the planning phase of this project, all AIRS MOU users will be contacted regarding your agencies participation in the State’s 800 MHz rebanding project. 

Rebanding Update 05/14/2014   

The Arizona Interoperable Channels Plan establishes requirements and/or recommendations for programming of statewide interoperable channels into subscriber units and to provide guidance on the use of the interoperable channels during day-to-day and emergency use. The plan includes standardized programming guides intended to enhance the capability for increased interoperable communications throughout the state in the VHF, UHF, 700 and 800 MHz bands and strongly encourages that each agency incorporate these channels into their channel plan, train their users on their use, and utilize these channels during training, exercises and events involving multiple agencies and jurisdictions to assure proficiency.

The plan recommends that 800 MHz radio users program their units to include an interoperability deck or zone of 800 MHz conventional channels configured as follows in the pre-rebanded environment.

The AZ DPS Wireless Systems Bureau (WSB) strongly encourages all AIRS system users to add post rebanded AIRS 800 MHz interoperability zone (or channels) to all of their radios during a first touch of subscribers as part of the rebanding effort.

DPS WSB will reband AIRS state supported infrastructure after all users have completed first touch (by region or statewide). Once the AZ AIRS sites are rebanded statewide, and your agency concludes that other adjacent states that you may interoperate with have also completed rebanding any other 800 MHZ mutual aid channels that your agency may utilize, all AIRS systems user may remove the pre-rebanded AIRS 800 Zone (or channels) from all their radios during second touch.

This multi-phase approach will allow AZ 800 MHz radio users to maintain the ability to operate on both the new and old AZ and national NPSPAC mutual aid channels until rebanding is complete in all affected areas along the US/Mexico border. This is critical to ensuring AZ 800 MHz radio users are able to utilize AZ and national NPSPAC mutual aid channels both in receiving assistance from responders coming from areas that have not rebanded or to provide mutual aid assistance in areas that may or may not have rebanded.

Additional technical approaches may be possible for groups that program specific regional AIRS 800 MHz channels interleaved within operational zones of their radios, especially in areas that operate their own trunked radio systems. Please contact your system or rebanding vendor should your agency have more questions regarding potential options.

Until the schedules for major 800 MHz system operators in AZ as well as non-affiliated AIRS system users, those included on the AZ DPS rebanding plan, are better defined, the DPS WSB cannot supply a projected schedule for the rebanding of the AIRS system infrastructure. As soon as this information becomes available, this site will be updated to include this information.
