Embodiment Construction

[0014] Please refer to figure 1 , figure 1 It is a schematic diagram of using the interface device 16 of the present invention to communicate with the wireless local area network 14 and the wireless wide area network 10 . Such as figure 1 As shown, the interface device 16 of the present invention can be set in a mobile wireless area network 14, such as a bus, an airplane, or a large vehicle such as a train. For an access point (AP) device, the format of the data transmitted in the WLAN 14 must conform to the regulations of IEEE 802.11a / b / g. In the space formed by these mobile wireless local area networks 14, there are multiple mobile clients 18 (mobile clients), that is, the passengers of large-scale vehicles with mobile communication equipment, these mobile clients 18 can use both In some WLAN 14 structures, different locations in the vehicle select different times for internal connection communication within the WLAN 14 . The interface device 16 of the present invention ...

Abstract

An interface device, it is a access point device used in mobile communication and connecting wireless area network with wireless wide area network, this interface includes entity layer circuit and data transmission layer circuit, the entity layer circuit includes first connection end and second connection end; the data transmission layer circuit includes first medium access controller, second medium access controller, a flow controller and a bridge, the bridge is used for switching form of data.

Description

technical field [0001] The invention provides an interface device, especially an interface device which directly converts data packet form in a data transmission layer circuit to connect a wireless area network and a wireless wide area network. Background technique [0002] Wireless networking technologies can range from global voice and data networks (which allow users to establish long-distance wireless connections) to optimized infrared and radio frequency technologies (which can be used for short-range wireless connections). Common devices using wireless networks include portable computers, desktop computers, laptop computers, personal digital assistants (PDAs), mobile phones, stylus computers, and pagers. Wireless technology offers many practical values. For example, mobile users may use their cell phones to access email. Passengers using portable computers can connect to the Internet through basic stations installed in airports, train stations and other public places...
