description The invention provides a data scheduling device and a method supporting service quality in a wireless MESH network. The device of the invention comprises two schedulers, wherein in the primary scheduler, a service sorting manager queues requests according to service types; a scheduling queue selector I selects a request queue to be scheduled; a bandwidth allocator I virtually allocates bandwidths; a transmission mode selector provides a modulation encoding mode corresponding to connection; a user bandwidth statistic device combines discontinuous bandwidths into continuous bandwidth and sends a primary scheduling result to a source node; in the secondary scheduler, a scheduling selector II selects service of priority scheduling from the service queue; a bandwidth allocator II computes the largest/smallest sending quantity of the frame, differentiates the grades of the services and schedules the services frame by frame; and a data mapper sends the scheduled data to a physical layer and transmits to a destinatio
