RF (Radio Frequency)
Radio Frequency (RF) technologies refer to the use of electromagnetic waves (typically in the 3 kHz to 300 GHz range) to transmit data wirelessly. This includes:
🔧 Common RF Applications:
- Wi-Fi (2.4 GHz, 5 GHz, 6 GHz)
- Bluetooth
- Cellular networks (3G, 4G, 5G)
- Radio and TV broadcasting
- RFID (Radio-Frequency Identification)
- Two-way radios / Land Mobile Radio (LMR)
- Public Safety DAS (Distributed Antenna Systems)
- Emergency Responder Radio Coverage Systems (ERRCS)
🛠️ In the context of fire and building safety (NFPA, etc), RF technologies are:
- Critical for first responder communication
- Used in DAS to ensure radio coverage in hard-to-reach areas (e.g., basements, stairwells)
- Must comply with codes like NFPA 1225, IFC, and IBC
