200810481 IX. Description of the invention: [Technical field to which the invention pertains] The method and the I method of the present invention relate to a wireless network cable,

Wireless network transmission... Send/receive (station) Take the W in the super box. [Prior Art] Fig. = is a request for coffee according to the prior art. Γ^Γ=A diagram of a hali-duplex wireless network that sends (de"to send (10) signals. Often, wireless networks use a half-duplex mode that cannot perform both data transmission and reception. When the wireless network uses half-duplex mode to access the wireless medium #, the RTS δ Ι Ι 111 and the CTS signal 121 are used to prevent collision of the media access signal. First, the transmission station 11 having the frame to be transmitted transmits The RTS signal 111' is used to initiate the transmission process. Then, all the peripheral stations that have received the RTS dl number 111 stop generating radio waves (racji〇wave). When the receiving station 120 receives the RTS signal 111, the receiving station 120 transmits the CTS signal. 121. In response, the CTS signal 121 also prevents all peripheral stations from generating radio waves. The transmitting station 110 that has received the CTS signal 121 transmits a block 112 to the receiving station 120. The receiving station 120 then transmits an acknowledge signal (acknowledge signal). 122 to the transmitting station 110 in response, and the transmitting station 110 receives the confirmation signal 122. 200810481 25064pif.doc Carrier sensing multiple access with collision avoidance (Carri Er sense multiple access with collision avoidance (CSMA/CA) is a media access control (MAC) algorithm commonly used in wireless area network (LAN) environments (algorithm) Provided by a distributed coordination function (DCF), the distributed coordination function checks whether the radio link is cleared by the transmitting station 110 before transmitting the block 112, and at each The end point of block 112 is compensated (back_off) to prevent collisions between other stations, similar to Ethernet. Carrier sensing is used to determine if media is available and is divided into Physical carrier sensing function and virtual carrier sensing function. The physical carrier sensing power is summed into: the physical layer and depends on the media used. And modulation mode. The network configuration vector (netw〇rk all〇cati〇n vector, NAV) provides virtual carrier sensing, and when the media is retained, The network configuration vector is a timer that indicates time information. The network configuration vector is included in the frame header of each of the RTS signal 111 and the CTS signal 121, and then transmitted. The transmitting station 11 and the receiving station 120 set the time required to complete their network configuration vector operations, thereby preventing other stations from using the media. At the same time, timing is based on a hyperframe in the wireless personal area network (PAN) (criminal (four) such as Cong). 200810481 25064pif.doc FIG. 2 is a diagram showing a superframe according to the prior art. As shown in FIG. 2, the superframe 200 sequentially includes a beacon period peri〇cj) 210, a contention access period 220, and a channel time allocation period 230. For example, non-synchronous data or control commands are transmitted or received during the contention access period 220. The channel time configuration period 230 includes a channel time allocation (CTA) 232 and a management CTA (MCTA) 231. For example, CTA232 is used to transmit or receive control commands, synchronization data, or asynchronous data. The length of the contiguous access cycle 220 is set based on the access point and by the beacon box distributed in the beacon period 210 to transmit the contention access period 220 to stations in the network. In the contention access period 220, CSMA/CA is used as a media access method. On the other hand, the channel time configuration period 230 uses time-sharing multiple memory

A time division multiple access (TDMA) system in which a specific time window (timewind〇w) is provided for each station. The access point configures a channel time for a device that requests media access and transmits data to or receives data from the corresponding station during this time. The MCTA 231 is configured for a pair of stations that need to transmit/receive data and is used as a shared CTA that can access the TDMA system or use a slotted aloha protocol. Methods of transmitting compressed data over a multi-billion GHz band and methods of transmitting uncompressed data via a tens of millions of Hz sf have been used to transmit data. Because the size of the uncompressed 200810481 25064pif.doc data is larger than the size of the compressed data, the uncompressed data can only be transmitted through the band of tens of millions of Hertz, and in addition, even during the transmission. In the case of loss, the impact on the output of uncompressed data is less than the effect on the output of the compressed data. Blowing "In wireless communication, the beacon box includes the time course 2 for accessing the network media.
