However, it currently affects the transmission of data between mobile terminal equipment and central equipment. For example, the wireless communication protocol cannot meet the requirements of the user to receive or transmit quickly, and the transmission of data is limited to the data transmission speed: the conventional wireless communication architecture uses point transmission reliability for the purpose. Although the practice can be two: "Capital: for generations;; but at the expense of the original is very limited and the responsibility of the non-occupation:: f broadcast method for data transmission, thereby avoiding the cost. Right, / / mode is At the expense of data transmission reliability: In this case, the industry has proposed that most of the operations of the central equipment 19167 J300299 - one of the winter end equipment will transmit the data packet of its datapackage to the central equipment, For the central device to receive the transmission status of each mobile terminal device according to the feedback of the feedback message, for example, if the data transmission between the central device and its mobile terminal device is correct, the job is based on the line. The transmission of the secret device feedback 2 determines that the data transmission between the mobile terminal and the mobile terminal device is correct; for example, if the ▲ medium and the „ If the transmission error occurs, then the data backup error between the mobile terminal and the mobile terminal device is determined according to the transmission message fed back by the mobile terminal device. At this time, the central packet f is newly transmitted, so that the degree can be determined. Uplifting two;:, @的秘秘' However, because each mobile terminal device sets the material in the receiving center: the data packet transmitted by the party, the mobile terminal device receives the resource packet (4), the packet loss occurs, the device feedback The mechanism for transmitting messages is to improve the sinfulness of the 1, 2, and 4 mechanisms for the entire performance. However, the performance of this one line is much less effective. This _ device sends::: The loss of the seal ί, all need to be through the above mobile terminal: Bay U center device' thus still waste wireless bandwidth. The center 2 === mobile terminal equipment requires frequency media data and / or video media; = immediately borrow m 枓) instant transmission, because the data transmitted between the center and the current terminal equipment is: Instantness, in order to meet the demand for video transmission speed. ί 夕 media sighs the tribute 19167 6 1300299 槿 目前 2 current wireless communication architecture is generally a wireless embedded rack • increased. The limitation of the data is related to the difficulty of data transmission. How to propose a technique for wireless transmission of data to overcome the conventional knowledge [invention], and to solve the problem that the industry needs to solve. : In view of the above disadvantages of the prior art, the main object of the present invention is > and transmission speed.
