Technical Advancements in Bluetooth 6.0 – Bluetooth 5.4 vs Bluetooth 6.0

Bluetooth 6.0 introduces several key features that elevate its capabilities, particularly in positioning accuracy, connection stability, and energy efficiency. Let’s delve into these innovations:

1. Decision-Based Advertising Filtering
   This feature significantly improves the efficiency of Bluetooth Low Energy (LE) devices by eliminating redundant advertising packets. It ensures that only one broadcast packet per device is received, reducing congestion and enhancing network performance.
2. Monitoring Advertisers
   Enhancing scanning efficiency, Bluetooth 6.0 allows devices to notify the host when target devices enter or exit the range. This feature is particularly useful for applications requiring dynamic interactions, such as proximity-based services.
3. Isochronous Adaptation Layer (ISOAL) Enhancement
   By transmitting larger data frames in smaller link-layer packets, this enhancement reduces latency and increases the reliability of data transfer, particularly in high-bandwidth applications like media streaming.
4. LL Extended Feature Set
   Devices can now exchange comprehensive link-layer feature information, enabling better compatibility and leveraging shared capabilities for optimized performance.
5. Frame Space Update
   This replaces the fixed 150 µs interval between data packets with a negotiable interval, enhancing data throughput and reducing transmission delays.
