Per the FCC, on January 1, 2013, all public safety and business industrial land mobile radio systems operating in the 150-512 MHz radio bands must cease operating using 25 kHz efficiency technology, and begin operating using at least 12.5 kHz efficiency technology. This deadline is the result of an FCC effort that began almost two decades ago to ensure more efficient use of the spectrum and greater spectrum access for public safety and non-public safety users. Migration to 12.5 kHz efficiency technology (once referred to as Refarming, but now referred to as Narrowbanding) will allow the creation of additional channel capacity within the same radio spectrum, and support more users.

ACD will work with public safety agencies and can perform the following services to ensure Narrowbanding compliance.

• FCC Regulatory Service, Frequency Coordination in VHF and UHF Bands
• System Transition and Migration from Wideband to Narrowband per FCC Requirements
• Engineering Design & Planning
• Project Management
• Needs Assessment and Conceptual System Design
• Grant Assistance
• Interoperability Strategies & Planning
• Single & Multisite Propagation Maps
• Indoor/Outdoor Coverage Testing
