FCC Licensing

	Existing radio systems that currently operate on frequencies ranging between 150-512 MHz must convert their systems to one that has either a data rate of 4800bps/6.25 kHz or one voice path per 12.5 kHz by January 1, 2013 This deadline pertains to Public Safety, Industrial, and Business licensees
	Applications for 25 kHz (wideband) will be accepted until January 1, 2011. After this date, applications for greater than 12.5 kHz bandwidth will be accepted only if the equipment meets the efficiency standard of one voice channel/12.5 kHz bandwidth or 4800 bps/6.25 kHz (9600 bps for 12.5 kHz; 19.2 bps for 25 kHz)
	The January 1, 2011 deadline applies to "New" systems as well as modifications to existing systems. After this date, applications to modify to 25 kHz systems which result in an expanded service contour will be accepted only if the equipment meets the efficiency standard of one voice channel/12.5 kHz bandwidth or for data, 4800 bps/6.25 kHz (9600 bps for 12.5 kHz; 19.2 Kbps for 25 kHz)
	Equipment on 25 kHz channel may not be manufactured or imported after January 1, 2011. After this date, equipment operating at greater than 12.5 kHz bandwidth must meet the efficiency standard of one voice channel/12.5 kHz bandwidth or 4800 bps/6.25 kHz.
	This ruling does not apply to Part 90 paging-only frequencies.

Frequently Asked Questions

Q - Will we need to change frequencies or move to 800 MHz?

A - No. Narrowbanding does not require moving to another frequency band, you merely reduce the bandwidth of the channel(s) you are now using.

Q – Will this reduce our coverage?

A – Little if any. You may have to survey your system and area of operation. Only a thorough analysis of your coverage requirements can tell for sure.

Q - Will we have to buy new radios?

A - Possibly, most radios purchased in the last 6-8 years are already narrowband capable. They only need to be re-programmed.

Q – Will we have to convert to digital?

A– No. However, many agencies are using this opportunity to upgrade to digital technology. Most digital radios are dual mode capable and can operate in wideband analog as well as narrowband analog and digital. Digital is also more immune from adjacent channel interference along with features unavailable in analog.

A license granted by the Federal Communications Commission (FCC) is valid for 10 years. Rassbach Communications can assist you when applying for a new license, renewing, or modifying an existing license. We can complete the FAA study and help with your tower registration.
