H04W WIRELESS COMMUNICATION NETWORKS (broadcast communication H04H; communication systems using wireless links for non-selective communication, e.g. wireless extensions H04M1/72)
Description
H04W encompasses wireless communication systems and networks that transmit signals without fixed physical connections between transmitter and receiver. This subclass covers technologies including cellular mobile networks (2G through 5G and beyond), wireless local area networks (WLAN), satellite communications, and short-range wireless protocols such as Bluetooth and Wi-Fi. It includes methods and apparatus for network access, resource allocation, mobility management, and signal transmission across various frequency bands and modulation schemes. Related standards development, system architecture, and interoperability mechanisms between different wireless technologies fall within this scope.
