    • A wireless network permits wireless devices to determine their own location and receive location-based services. The network includes a communication server coupled to a plurality of access points and at least one mobile wireless device that wirelessly communicates through the access points. Each wireless device includes a location table through which the wireless device can determine its physical location. The location table includes the physical location of the various access points indexed by their network addresses. When the wireless device communicates with an access point, the access point provides the wireless device its address. The wireless device uses the address of the access point as an index into the location table to determine its own location based on the location of the access point. Once the wireless device has determined its own physical location, it requests location-based services from or through the communication server.
    • 无线网络允许无线设备确定自己的位置并接收基于位置的服务。 网络包括耦合到多个接入点的通信服务器和通过接入点进行无线通信的至少一个移动无线设备。 每个无线设备包括无线设备可以通过该位置表确定其物理位置的位置表。 位置表包括由其网络地址索引的各种接入点的物理位置。 当无线设备与接入点通信时,接入点为无线设备提供其地址。 无线设备使用接入点的地址作为位置表的索引,以基于接入点的位置来确定其自己的位置。 一旦无线设备确定了自己的物理位置,它就从或通过通信服务器请求基于位置的服务。

    • A wireless network adapter for establishing wireless communication links between electronic devices. In one embodiment, the wireless network adapter comprises wireless communication circuitry encased in a shell in the form of a detachable molding element of an electronic device. The wireless network adapter further comprises a bus connector adapted to couple the wireless communication circuitry to an expansion bus when the shell is attached to an outer surface of an electronic device. The wireless network adapter is a fully integrated solution further comprising an RF antenna for communication with a wireless network and a radio modem comprising a radio, a receiver, and modulation circuitry. The RF antenna in the wireless network adapter may take one of several forms. The antenna may be a dedicated unit housed within the shell of the wireless network adapter. Alternatively, the antenna may form a part of the outer shell of the adapter or it may form a part of a company logo located on the shell the adapter. The wireless network adapter is installed in an electronic device such as a portable computer. The electronic device comprises, at a minimum, a system microprocessor, an expansion bus, a read-writeable memory device, an input/output device, and an expansion port connected to the expansion bus that is configured to accept the detachable wireless network adapter. Another embodiment of the present invention comprises an electronic device equipped with an external sleeve configured to accept a wireless network adapter insert.
    • 一种用于在电子设备之间建立无线通信链路的无线网络适配器。 在一个实施例中,无线网络适配器包括以电子设备的可拆卸模制元件的形式封装在外壳中的无线通信电路。 无线网络适配器还包括总线连接器,其适于在外壳附接到电子设备的外表面时将无线通信电路耦合到扩展总线。 无线网络适配器是完全集成的解决方案,其进一步包括用于与无线网络通信的RF天线和包括无线电,接收机和调制电路的无线电调制解调器。 无线网络适配器中的RF天线可以采用几种形式之一。 天线可以是容纳在无线网络适配器的外壳内的专用单元。 或者,天线可以形成适配器的外壳的一部分,或者它可以形成位于外壳上的适配器的公司徽标的一部分。 无线网络适配器安装在诸如便携式计算机的电子设备中。 电子设备至少包括被配置为接受可拆卸无线网络适配器的系统微处理器,扩展总线,可读写存储器设备,输入/输出设备和连接到扩展总线的扩展端口。 本发明的另一个实施例包括配备有外部套筒的电子设备,其被配置为接受无线网络适配器插入件。
