Advanced Wireless Protocols

Advanced wireless protocols include Bluetooth LE Channel Sounding, which uses phase and timing measurements of radio signals to determine precise distances between devices with centimeter-level accuracy. This enables secure proximity detection and distance-based access control without requiring additional hardware. Wi-Fi 7 and emerging Wi-Fi 8 standards incorporate advanced geolocation capabilities that can determine device positions within indoor environments using signal strength, time-of-flight, and angle-of-arrival measurements.

Bluetooth LE Channel Sounding provides secure distance measurement resistant to relay attacks, making it valuable for keyless entry systems, contactless payments, and access control. Wi-Fi 7/8 geolocation enables indoor positioning systems that can track devices throughout buildings, supporting applications like asset tracking, navigation, and location-based services. These protocols integrate positioning capabilities directly into standard wireless communication, eliminating the need for dedicated positioning infrastructure while providing the accuracy needed for many consumer and enterprise applications.
