200409494 V. Description of the invention (2) Seven levels of transmission. The closest to the user terminal is the physical layer in the seven layers of the network. The physical layer refers to the hardware network interface or the communication medium. The part is mainly to convert the actual hardware signal into a signal that the computer can accept. The control environment of this layer has no standard agreement content, but is produced by the hardware manufacturer. The second layer up is called the data link layer, which mainly provides computers and computers to send data packets to the other party on the physical network without error. It also contains the network layer, the transport layer, and so on. Wireless network types are like fixed networks. Wireless networks can be divided into different types according to the distance that data can be transmitted, including wireless wide area network (WWAN), wireless metropolitan area network (WMAN), wireless local area network (wlan), And wireless personal networks (WPAN). Closely related to the present invention are wireless wide area networks, wireless local area networks, and wireless personal networks (WPAN), where wireless wide area network technology allows users to establish wireless connections on remote public or private networks. These connections can be made in a wide area (such as cities or countries) using multiple antenna stations or artificial satellite systems maintained by wireless service providers. , And wireless LAN technology allows wireless connections in small areas, such as in a company or teaching building, or in a public space, such as an airport. Wireless LANs can be used in temporary offices or other spaces where extension cables are prohibited, so that users can choose to work at different times in different locations within the building. In a wireless LAN infrastructure, a wireless workstation (with radio

Description of the Invention (3) The network card or external modem device) will be connected to a wireless access point (AP), which functions like a bridge between a workstation and an existing network backbone. . In 1997, IEEE passed the wireless LAN ^ 8 0 2 · 1 1 standard, designated! Up to 2 million bits per second (Mbps)

Data transfer rate. The new governing standard ΙΕΕΕ 〇2. Ua / b / g sets out the general specifications for detailed transmission data formats and transmission rates in wireless $ WANs. After that, the wireless personal network technology allows users to create surround In personal space, the communication transmission range is up to 10 meters. At present, the two main WPAN technologies are Bluetooth and infrared. Bluetooth uses radio waves to transmit data. It can penetrate walls, pockets, and briefcases. Another type of connection that is very close (within one meter) is to establish an infrared connection. To standardize the development of WPAN technology, I £ £ e established the IEEE 8 0 2 · 1 5 working group of WPAN 'with the main goals of low complexity, low power consumption, interoperability, and coexistence with the IEEE 8 0 2 · 11 network. "The ideal of a mobile information service environment is to provide a ubiquitous information environment so that information users can use various wired or wireless transmission networks to use information resources on the network at any time and at any time. However, Today's mobile communication capabilities are not enough to provide mobile users with cost-effective wireless communication to support real-time multimedia information transmission.
