What is Narrowbanding?

The Federal Communications Commission (FCC) started the narrowbanding proceedings, also known as refarming, almost twenty years ago in an effort to promote more efficient spectrum use in the 150-174 MHz (VHF) and 421-512 MHz (UHF) Part 90 radio frequency bands. The FCC has released numerous rulings during this time defining the requirements and mandating specific deadlines.
The purpose of this document is to provide you with the narrowbanding facts, starting with the key dates and requirements you need to know, followed by exemptions and additional information, how Motorola products meet the requirements, and steps licensees should take starting now.
KEY DATES AND REQUIREMENTS:
The FCC is mandating all Public Safety and Industrial/Business licensees convert existing 25 kHz efficiency operations in the VHF and UHF bands to minimum 12.5 kHz efficiency analog or digital operation, and that going forward they implement no more 25 kHz efficiency systems. To implement this mandate, the FCC developed rules and deadlines that impact both radio users and equipment providers.
