摘要： There is elucidated a method of communicating data packets (210; 520) within a data communication network (10). The network (10) comprises communication nodes (30a, 30b, 30c, 40), wherein a first nodal set (30a, 30b, 30c) comprises nodes which are operable to communicate via a communication medium with a second nodal set (40) comprising at least one of said nodes (30a, 30b, 30c, 40). The method comprises steps of: (a) mutually synchronizing together two or more nodes of said first nodal set; and (b) simultaneously in a synchronized manner transmitting one or more data packets from the mutually synchronized two or more nodes of said first nodal set via said communication medium for substantially simultaneous reception at said second nodal set (40). The network (10) is susceptible to being simpler to implement in comparison to comparable contemporary communication networks, as well as potentially providing a better quality-of-service (QoS) especially when handover from one access point node to another is considered.
