Implementation and Demonstration of eBCS Concept in IEEE 802.11-19/1999r0
This presentation showcases the implementation and demonstration of the eBCS concept, including the system architecture, utilization of eBCS AP and STA, web server functionality, and data transmission processes. It covers the use of LDPC-Staircase/Triangle for packet transmission, IP multicast for data delivery, and digital signature for security. The presentation also details the interaction between eBCS AP and eBCS STA, the process of receiving and reconstructing contents, and enabling transmission rate configuration. Overall, it provides a comprehensive overview of how eBCS operates within the IEEE 802.11 framework.
