Apparatus and method for detecting a wireless access point for wireless network communication

摘要

A wireless network communication card usable with a host apparatus is disclosed. The wireless network communication card includes an access point detection circuit that detects a wireless access point through a wireless antenna. A power inlet to which power is supplied in response to an access point detection request from a user when the power of the host apparatus is suspended, the power inlet being connected to the access point detection circuit is included, as is an indicator coupled to said access point detection circuit that indicates a presence of an available wireless access point in response to a detection by said access point detection circuit.

主权项

1. A host computer comprising:
a wireless network communication card having an access point detection circuit for detecting a wireless access point, wherein said access point detection circuit is capable of being powered by a main power source or a battery power source, wherein said wireless network communication card further includes a memory device for storing instructions to operate said access point detection circuit without activating an operating system of said host computer; an access point detection request button, coupled to a latch circuit of said wireless network communication card, controls a switch between said main power source and said battery power source such that power is provided to said access point detection circuit from said battery power source regardless of whether or not said main power source from said host computer is available, after said access point detection request button has been activated, wherein said switch is controlled by said latch circuit via an inverter transistor circuit; and an indicator, coupled to said access point detection circuit, for indicating a presence of an available wireless access point in response to a detection of said wireless access point by said access point detection circuit.
