Legacy technologies, like Bluetooth and Wi-Fi have seen many innovations and iterations. Fundamentally new technologies like Narrowband IoT/5G or Low-Power Wide Area Networks (LPWAN) have found rapid acceptance in the markets. Today preparation for 6G mobile networks is in full swing. With the 21st congress program, we will continue to provide information on novel wireless technologies and applications. We are very much looking forward to your interesting submission and to meeting you in Munich at the Wireless Congress: Systems & Applications on November 13th and 14th, 2024 in Munich, Germany – parallel to electronica!
