FCC Licensing
Almost all business two way radios require an FCC, Federal Communications Commission, license. Rassbach Communications submits the application to a coordinating agency and then to the FCC for final approval. Once the license has been approved by the FCC it is valid for 10 years. We are able to help you with new licenses modifications, FAA studies, and tower registration.

Narrowband Information and Deadlines
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) .
Frequently Asked Questions
Q- Will we need to change frequencies or move to 800Mhz?
A- No, narrowbanding does not require moving to another frequency band.
Q- Will we have to buy new radios?
A- Possibly, most radios purchased in the last 6-8 years are already narrowband capable. They will only need to be reprogrammed.
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 and narrowband analog and digital. Digital is also more immune from adjacent channel interference along with features unavailable in analog.
