Embodiment Construction

[0014] figure 1 An example of a wireless network system 10 is illustrated in accordance with one aspect of the invention. The wireless network system 10 can comply with one of the IEEE 802.11 standard versions for WiFi networks. Wireless networking system 10 includes WiFi access point (AP) 12 that transmits radio frequency (RF) communications over wireless communication link 16 via antenna 14 to multipurpose device 18 via antenna 20 . WiFi AP 12 and one or more other WiFi access points (APs) can connect to the same or different wired networks (not shown). The multipurpose device 18 performs periodic channel scanning to determine which of a plurality of APs to select to connect to and receive resources from a given WiFi network. An AP can be selected based on one or more parameters (eg, capacity, signal strength, selected users, etc.) associated with the selected AP. When the multipurpose device 18 receives resources from selected APs, it acts as a station (STA) device.

Abstract

Systems and methods for channel scanning for multirole device are disclosed. One implementation relates to a method for servicing functions by a multirole device. The method comprises dividing a channel scan over a plurality of channels into a plurality of channel scan time periods (152), and repeatedly time division multiplexing a time period for the servicing of one of a station (STA) function and an access point (AP) function, a time period for the servicing of the other of the STA function and the AP function, and a channel scan time period for each of the plurality of channel scan time periods (156).

Description

technical field [0001] The present invention relates generally to electronic devices, and more particularly to systems and methods for channel scanning of multipurpose devices. Background technique [0002] Wireless and mobile networks based on IEEE 802.11, also known as Wireless Fidelity (WiFi), have experienced rapid growth. WiFi is a mechanism that allows electronic devices to exchange data wirelessly over a computer network. A WiFi-enabled device, such as a personal computer, video game console, smartphone, tablet, or digital audio player, can connect to a network resource, such as the Internet, via a wireless network access point. Access points (or hotspots) have an indoor range of about 20 meters (65 feet) and a greater outdoor range. Hotspot coverage can consist of as small as a single room with walls that block RF signals, or as large as a larger area of ​​several square miles covered by multiple overlapping access points. A wireless access point (WAP) connects a ...
