What are Frequency Bands?

Frequency bands are specific ranges within the RF spectrum (3 kHz to 300 GHz) allocated for different types of wireless communication.

• Cellular Networks: Mobile carriers use licensed frequency bands, typically ranging from 600 MHz to 5 GHz, with newer 5G networks extending into the mmWave spectrum (24 GHz – 100 GHz) for ultra-fast speeds and low latency.
• ERRCS (Emergency Responder Radio Communication Systems): Public safety and emergency responder networks operate in dedicated frequency bands, such as the VHF (150-174 MHz), UHF (450-512 MHz), and 700/800 MHz bands, ensuring reliable communication for first responders inside buildings and in emergencies.

Each band is assigned based on performance needs—lower frequencies (e.g., 600 MHz, 700 MHz) travel farther and penetrate buildings better, while higher frequencies (e.g., mmWave) provide more bandwidth but cover shorter distances.
