Problems solved by technology

If a commercial electronic device communicates with both the Bluetooth channel and the WLAN / WiMAX channel, since the frequency band of the WLAN / WiMAX channel may overlap with the frequency band of the Bluetooth channel, the signal interference between the simultaneously transmitted Bluetooth signal and the WLAN / WiMAX signal may introduce signal transmission and reception errors

Embodiment Construction

[0019] In order to make the above and other objects, features, and advantages of the present invention more comprehensible, the preferred embodiments are listed below, together with the accompanying drawings, and are described in detail as follows:

[0020] see figure 2 . figure 2 It is a schematic block diagram of a device 200 capable of Bluetooth and WLAN communication according to an embodiment of the present invention. The device 200 includes a Bluetooth module 202 for Bluetooth communication and a WLAN chip 204 for WLAN communication. The WLAN chip 204 includes two sub-modules, a WLAN module 208 for WLAN communication and a packet-traffic arbitration (PTA) module 206 . To avoid interference between the Bluetooth signal sent by the Bluetooth module 202 and the WLAN signal sent by the WLAN module 208 , the Bluetooth module 202 must be coupled to the WLAN chip 204 to negotiate signal transmission and reception to avoid signal conflict. To reduce hardware cost and power ...

Abstract

The invention provides an apparatus capable of wireless communications and methods for operating the same. In one embodiment, the apparatus comprises a packet traffic arbitration (PTA) module and a first wireless transceiving module, and the first wireless transceiving module is connected to the PTA module via a wire. The first wireless transceiving module sends a first request for performing a first signal transceiving to the PTA module via the wire, receives a first response to the first request via the wire, and performs the first signal transceiving when the first response indicates that the first request has been granted by the PTA module. The invention prevents the signal interference problems during simultaneous transmission of Bluetooth signals and WLAN / WiMAX signals.

Description

technical field [0001] The present invention relates to coordination among Bluetooth, wireless local area network (Wireless Local Area Network, hereinafter referred to as WLAN) and microwave access global interoperability (Worldwide Interoperability for MicrowaveAccess, hereinafter referred to as WiMAX) communication, especially about the use of Bluetooth , A device and a method for wireless communication between WLAN and WiMAX. Background technique [0002] For commercial electronic products such as mobile phones, both Bluetooth and WLAN are important communication channels. However, both Bluetooth and WLAN channels communicate via the 2.4GHz Industrial, Science, and Medical (ISM) frequency band. see Figure 1A , which is a schematic structural diagram of a WLAN frequency band conforming to the IEEE 802.11b standard. Three static non-overlapping WLAN channels with a bandwidth of 22 MHz are spread over a frequency band ranging from 2400 Hz to 2483.5 Hz. see Figure 1B , ...
