![]() The Federal Communication Commission or its-certified facilities regulate these users indirectly. E.g., unlicensed wireless microphones, fixed and mobile TVBDs. Thus, they are not protected from interference. E.g., amateur stations, licensed wireless microphones, etc. However, the primary users have more rights than the secondary users. These include licensed users of the spectrum. Examples are digital and analog TV transmitters, cellular services, 2-way radios, etc. Therefore, these primary users have high interference protection. The Government gives some spectrum bands either on lease or as a property to some users. Note: The Government places Broadcast band 54-698MHz in a hierarchy. Tertiary Users: fixed and mobile TVBDs, medical telemetry devices, unlicensed wireless microphones. Secondary Users: Amateur radios, licensed wireless microphones, broadcast Tv camera control signalsĬordless phones, baby monitors, medical telemetry devices, hobbyist devicesīunched power cables, fluorescent fixtures, high voltage lightning Microwaves, X-rays, MRIs, Breakers, Arc welders, consumer electronics Wi-Fi devices, Bluetooth devices, Zigbee devices, and wireless USB devices Primary Users: FM/AM radio boosters and translators, Aural TV transmitters, Fixed and mobile broadband services, Digital and analog TV transmitters Intentional Radiators 900mhz and 2.4Bands Intentional Radiators: Broadcast Band(54-698mhz) Common Sources of Interference Natural Radiators These are the artificial technologies that use radio energy for sending communication signals. Although the FCC and product makers know about this, they can’t help it. Sometimes, devices emitting EMI are so small that one cannot filter them. For example, electrical contacts of a breaker. At times, these issues are purely unplanned. They are artificial technology that also emits such energy. However, these radiators do not exceed low frequencies except a few. These energies are lightning, intense solar magnetic storms, dust, or snowstorms. Some natural factors emit electromagnetic energy. There are some common interference issues.
