Advantages of BEC 900 MHz Frequency-Hopping RF Systems
A 900 MHz frequency-hopping RF system offers several advantages over technologies like Wi-Fi, Bluetooth and other RF frequencies, particularly in terms of range, interference resistance, and reliability. Here’s how it compares:
Frequency-Hopping Spread Spectrum (FHSS)
• Benefits:
• FHSS spreads the signal across multiple frequencies within the 900 MHz band, rapidly switching channels according to a pseudorandom pattern.
• This makes the system highly resistant to:
• Jamming: Very difficult for attackers to jam the signal without covering the entire frequency range. Wi-Fi systems are susceptible to this issue.
• Interference: Reduces the risk of interference from other devices operating on a single frequency.
900 MHz Range
• Benefits:
• 900 MHz signals have better propagation characteristics than higher-frequency signals (e.g., 2.4 GHz or 5 GHz).
• They penetrate walls and obstacles much more effectively, making them ideal for large facilities like hospitals, warehouses, retail stores, or outdoor environments.
• Typical range: Up to several hundred meters indoors and much further in line-of-sight conditions like outdoors.
Interference Resistance
• The 900 MHz band is typically not congested like the 2.4 GHz or 5 GHz bands, which are used by Wi-Fi, Bluetooth, and many consumer devices.
• It is not prone to interference from microwaves, cordless phones, and other common household devices like Wi-Fi technologies.
Power Efficiency
• Benefits:
• 900 MHz systems require less power for transmission compared to higher-frequency systems, making them suitable for battery-operated panic buttons or portable devices.
Security
• 900 MHz FHSS inherently adds a layer of security by making it difficult for attackers to predict the frequency-hopping pattern. This is a big advantage for 900 MHz hopping frequency systems over Wi-Fi Based systems.
• Additional encryption can further protect the system from eavesdropping, spoofing, and replay attacks.
Use Cases for 900 MHz Frequency-Hopping RF
• Large Facilities: Hospitals, factories, or warehouses where long range and obstacle penetration are critical.
• Outdoor Applications: Campuses, farms, or remote sites needing long-range communication.
• Applications: Panic buttons, IoT sensors, or alarms that require low bandwidth but very high reliability and longer batty life.
