Embodiment Construction

[0023] figure 1 It is a schematic diagram of the first embodiment of the wireless network of the present invention. The first wireless network 100 in this embodiment includes a single access point AP, a first service providing device SD1, a second service providing device SD2, and a portable notebook computer NB. According to the present invention, the first and second service providing devices SD1 and SD2 and the notebook computer NB are arranged on an extension line 104 extending from a single access point AP. For example, if a user of a portable notebook computer NB wants to redirect a document to the nearest printer, and the first and second service providing devices SD1 and SD2 are two printers in the wireless network 100. In order to determine the nearest device, the first service providing device SD1, the second service providing device SD2, and the notebook computer NB all measure the signal strength of the signal 102 received from the access point AP. In this example, s...

Abstract

A wireless network includes a first wireless device, a second wireless device measuring the signal strength of a signal received at the second wireless device from the first wireless device, a third wireless device measuring the signal strength of a signal received at the third wireless device from the first wireless device, and a fourth wireless device measuring the signal strength of a signal received at the fourth wireless device from the first wireless device. The fourth wireless device selects a nearest wireless device being either the second wireless device or the third wireless device according to the measured signal strengths.

Description

Technical field [0001] The present invention is related to wireless networks, and more particularly, the present invention can be used to determine the closest wireless device to a portable wireless device in a wireless network. Background technique [0002] As wireless networks become more and more widely used, there is an increasing demand for a portable wireless device to determine the closest physical distance to a service provider device in the wireless network. In addition, in some applications, such as redirecting music playback to the nearest home audio device, or redirecting a file to the nearest office printer, usually a method must be used to determine Get the closest device (not just the close device). Of course, this decision procedure must be automatic and does not require user operations. This decision procedure can generally be referred to as "location awareness". [0003] However, the application of location recognition is still in the development stage. Microsof...
