4.9 GHz Band Licensing and Rules Overview 
  

Introduction 

 
In 2003 the FCC assigned the 4940-4990 MHz frequency band for Public Safety use. 
Any qualified agency may now obtain a license and use the band. This document 
provides a brief summary of FCC rules covering the 4.9 GHz band. Specific FCC rules 
are covered in Subpart Y in 47CFR part 90. 
 

Qualified Licensees 

 
The 4.9 GHz band is a licensed band available for use by public safety agencies. Any 
agency qualified for a 700 MHz license qualifies for a 4.9 GHz license. Generally this 
covers all government entities, private companies sponsored by a government entity 
(such as private ambulance services) and any organization with critical infrastructure 
(power companies, pipelines, etc.). 
 

Approved Uses of the Band 

 
The band may be used for any terrestrial based radio transmission including data, voice, 
and video. Point-to-point and multipoint operations are permitted. All multipoint and 
temporary (less than 1 year) point-to-point links are primary uses of the band. Permanent 
point-to-point links are secondary uses and require separate site licenses. Where 
interference cannot be eliminated by technical or operational modifications, primary 
users take precedence over secondary users. BreezeACCESS 4900 can be configured as 
point-to-point or multipoint system 
 

Prohibited Uses 

 
Aeronautical use and commercial use of the band is prohibited. 
 

Special Considerations 

 
After filing of a license application, the FCC will handle any required coordination for 
band use near the Canadian border. Also, use of the 4.9 GHz band must not interfere with 
radio astronomy observatories (radio quiet zones). 
 

Obtaining Licenses 

 
Both general and site-specific licenses may be obtained at any time through the Universal 
Licensing System (ULS) available at 

www.fcc.gov

. There is no charge and applications 

are processed within hours. Site-specific licenses must have endpoint coordinates 
submitted with the application. 

 
Time Limits 

 
There is no time limit for construction and operation under a general license. A site-
specific license must be operational within 18 months of the grant.
