Approaching Telecom Protocols with Erlang and Binary Analysis

This talk by Sebastian Weddmark Olsson at Code BEAM Europe 2023 covers how to approach new technological domains, specifically in the context of telecom protocols and codec development. Sebastian introduces his experiences working in the telecom industry, highlighting the complexities of various telecom components and their interconnections. He emphasizes the importance of understanding and interpreting binary data when building telecom codecs, showcasing Erlang's capabilities in this area. Sebastian also delves into tools like Wireshark for network analysis and the benefits of using the BEAM languages for efficient binary pattern matching. He further discusses his open-source project for decoding different telecom protocols, aiming to simplify the complexities of telecom specs by providing a unified and human-readable format.
