Wireless network system and method

A a method in a network, special is suitable for the low quality or a physical performance channel switching very high communication network, is of a wireless network (2), improves the transmission property the reduced bandwidth demand's situation. The method comprises the steps: (30) Packs a series of data to group (42) and application-aware; the edge of the series; and a ending the plug first packet (41); (41) to transmit the connected with first packet is received, wherein the groups (42) at least part and at least one first packet (41), and transmitting a confirm (60). The confirm (60) can be: The data packet and at least one first packet received; It is not the data packet is received and at least one first packet is received; Or multiple data set is received, and it is provided to group is received. Wherein the packet is not connected to the received reproduction of data packet and first packet for performing etching of the minimum, so that the number of the limiting number of communication for transmitting the data payload flowing.
