Understanding the Frequency Range
UHF technology operates within a broad frequency range of 300 MHz to 3 GHz. Access control readers typically operate around 902MHz-928MHz. This bandwidth allows for robust signal transmission, enabling UHF readers to communicate with credentials over greater distances compared to lower frequency technologies like LF (Low Frequency) or HF (High Frequency). The extended range of UHF signals opens new possibilities for access control applications in various environments.
Enhanced Read Range
One of the most significant advantages of UHF technology is its extended read range. UHF readers can detect and authenticate credentials from a considerable distance, sometimes reaching up to 25 feet. This extended read range offers numerous benefits, such as improved convenience for users, reduced bottlenecks at entry points, and enhanced overall efficiency in high-traffic areas. In addition, UHF readers such as AWID’s XM-700 reader for doors can provide touchless access to the door allowing a user to simply walk though the door provided the credential is within 7 feet of the reader. Standard LF readers typically operate within the 4” – 8” read range requiring the user to be in very close proximity to the reader.
Superior Signal Strength
UHF signals can penetrate different materials more effectively compared to other frequency bands. This characteristic makes UHF technology particularly suitable for access control applications in environments where obstacles such as walls, doors, or structures may obstruct signals. The superior signal strength of UHF readers ensures reliable authentication even in challenging physical conditions.
Compatibility with Multiple Credentials
UHF technology supports a wide range of credential types, including cards, key fobs, and even mobile devices equipped with UHF capabilities. This compatibility allows for flexibility in access control solutions, enabling users to choose the most convenient and secure credential format for their specific requirements. In addition, AWID’s complete line of UHF readers allows for a Long-range vehicle reader at a gate and standard UHF readers on doors so the user requires only one credential. This can be a significant cost savings as well as a convenient solution for facilities that have a gate and other doors such as a pool or clubhouse.
Interference and Noise Immunity
UHF technology boasts robust interference and noise immunity, ensuring reliable and accurate communication between readers and credentials. This characteristic is crucial in environments with multiple access points, crowded spaces, or areas prone to electromagnetic interference. The immunity to interference and noise helps maintain system integrity and mitigates the risk of false readings or authentication failures.
Regulatory Compliance
UHF technology adheres to globally recognized regulatory standards, ensuring compliance with industry regulations and guidelines. Compliance with international standards enhances the interoperability of UHF readers and credentials, allowing for seamless integration with existing access control systems and infrastructure.
Conclusion: UHF technology offers numerous advantages that make it an ideal choice for access control applications. With its extended read range, superior signal penetration, compatibility with various credentials, immunity to interference, and adherence to regulatory standards, UHF technology provides security dealers with a powerful tool to enhance access control systems. By understanding the capabilities and benefits of UHF technology, security dealers can leverage this technology to unlock new business opportunities and deliver advanced access control solutions to their clients.
