Professional two-way radios are used in commercial, industrial, emergency, and transportation settings where reliable, real-time voice communication is essential. These radios typically operate on licensed frequencies allocated by the Federal Communications Commission (FCC) and offer advanced features such as encryption, trunking, group calling, and extended range.
They are commonly used in:
- Public safety (police, fire, EMS)
- Maritime and aviation services
- Transportation and logistics
- Construction and manufacturing
- Hospitality and event management
Categories of Professional Use
1. Maritime Radio (VHF Marine Radio)
- Operates in the 156–174 MHz band
- Used for ship-to-ship, ship-to-shore, and distress communications
- Channels are internationally standardized (e.g., Channel 16 for emergencies)
- Required by law for many vessels, especially commercial and ocean-going craft
Features:
- DSC (Digital Selective Calling)
- Weather alerts
- High and low power settings
- Waterproof rugged design
2. Aviation Radio (Airband)
- Operates in the 108–137 MHz VHF range
- Used for communication between pilots and air traffic control (ATC)
- Channels are strictly regulated by the FAA and ICAO
Common Applications:
- Tower, ground, and approach control
- En route communication
- Airport operations
3. Land Mobile Radio (LMR)
- Used by public safety, government agencies, utilities, and transportation services
- Divided into:
- Public Safety LMR (PS-LMR): Police, fire, EMS
- Business/Industrial LMR: Construction, utilities, schools, hospitals
Technologies:
- Analog and digital modes (e.g., P25, DMR, NXDN)
- Trunked systems for efficient frequency use
- Encryption for secure communication
4. Taxi and Transportation Dispatch
- Operate primarily in UHF and VHF bands
- Often part of LMR or private licensed business radio networks
- Used for coordinating dispatch, navigation, and passenger management
5. Railroads (Railroad Radio)
- Operates primarily in the 160–161 MHz range
- Used for dispatch, train control, and yard communication
- Mandated by the Federal Railroad Administration (FRA) for safety compliance
6. Industrial and Commercial Use
- Warehousing, logistics, security, retail, and event management
- Commonly use business-band radios with FCC Part 90 licensing
- Emphasize clarity, durability, and multi-channel capabilities
7. Emergency and Incident Response
- Integrated into ICS (Incident Command System) protocols
- Often uses interoperable radio systems that bridge agencies
- Critical during natural disasters, large events, or public health crises
Licensing and Regulations
Most professional two-way radios require FCC licenses for operation. Agencies and businesses must:
- Apply for a Part 90 license (or relevant license class)
- Adhere to power output, frequency coordination, and call sign use rules
