Bluetooth vs. BLE

This lecture covers the differences between Bluetooth and Bluetooth Low Energy (BLE), including frequency bands, connection setup, power consumption, range, and frequency hopping. It also discusses adaptive frequency hopping, interference from WiFi, and scheduling in wireless networks, addressing issues like mixed traffic classes, perceived quality of service, and uplink capacity with multiple users. Various scheduling algorithms such as Round-Robin, Max Throughput, Proportional Fair, and Max-Min are explained, along with utility-based scheduling and QoS considerations. The lecture concludes with an overview of scheduling in OFDMA systems, including subcarrier allocation, signaling, and different scheduling strategies.
