Description

550916 V. Description of the invention (1) [Field of the invention] / The present invention relates to an access device for wireless local area networks, in particular, an access device for wireless local area networks, which can be different from and different from Dynamic terminals of transmission standards are linked. ', [Previous technology] Eighty-year years ^' The rapid popularity of the Internet has increased the number of regional networks built in the office to the court. In view of the advancement of digital wireless transmission technology and the inconvenience of cable installation, the demand for constructing a LAN 'or so-called wireless LAN by wireless transmission technology has increased significantly. … Wireless Local Area Networks (Wireless LANs) have developed considerably and are widely used in today's offices, retail stores, and large industrial facilities, such as warehouses or factories. These wireless LANs provide the transfer of data between computers, printers, servers, and other devices without the hassle and expensive installation steps of cables and connection terminals. For wireless LANs, a typical existing technology is IEE 802 · ΐι, whose f is a standard established by the Institute of Electrical and Electronics Engineers (IEEE). This standardized technology provides definitions from the physical layer to the sub-layer of data connection or the media access control layer (Media Access Control; MAC) under the open system connection model (OSen model). It includes specifications that can replace Ethernet or wired LAN transmission channels, and also provides roaming capabilities, a wireless-related additional feature.

Sequence Spread Spectrum) and infrared technology 〇 Wireless LAN products that use the IEEE standard are generally based on IEEE 802. 11 and IEEE 802.1 · 1 lb specifications. IEEE 802 · 1 lb is an extension of the original 80 2 · 1 1 'and has a more southerly speed'. The bandwidth operates at 2.4 GHz and is rated at a data transmission rate of 5.5 to 11 Mbps. The next generation of this standard, also known as IEEE 802.1 1 a, also known as HiperLAN2, will operate at a new bandwidth of 5 GHz and reach a higher data transmission rate of 54 Mbps. Compared with the spread spectrum technology used in Bluetooth, IEEE 802.1 1 and IEEE 80 2.1 1 b, it uses orthogonal frequency division multiplexing (〇rth〇g0nai FrequenCy

Division Multiplexing; OFDM) 〇 This IEEE 802.11a curtain can still be matched with ordinary Ethernet, without any switch selection. This IEEE 80 2 · 11χ standard is usually constructed as a pc card (pc card or PCMCIA card).

If the LAN supports wireless mobile terminals, such as laptops with I EEE 8 0 2 · 1 1 X functions or other small, bandable wireless data communication products, the LAN will also need to be connected to one or more Access point (also referred to as a base station). Each access device is connected to the LAN and has at least one radio communication, which forms wireless communication with the dynamic terminal. '
