Mobile communication device and wireless connection establishing method thereof

Abstract

The invention provides a mobile communication device and a wireless connection establishing method thereof. The wireless connection establishing method of the mobile communication device can be applied to a situation in which the mobile communication device uses a first wireless communication module and a second wireless communication module to establish a wireless connection with at least one peripheral device, wherein the signal range of the first wireless communication module is greater than that of the second wireless communication module. The method comprises the following steps that: the first wireless communication module is utilized to search peripheral devices located within the signal range of the first wireless communication module and establish first wireless connections with searched peripheral devices; state information of the second wireless communication module, which is corresponding to each peripheral device, is obtained through the first wireless connections; and then, the second wireless communication module is utilized to establish second wireless connections with the peripheral devices according to the state information.

Description

technical field [0001] The present invention relates to a device connection establishment method, and in particular to a mobile communication device and its wireless connection establishment method. Background technique [0002] The Wireless Gigabit Alliance (WiGig for short) is a wireless transmission technology for multi-gigabit data transmission per second on a 60 gigahertz (60 GHz) frequency band. When WiGig's wireless docking station is applied to the connection between consumer electronics and peripheral devices, it can break through the limitation of traditional wireless fidelity (Wi-Fi) transmission speed and provide a practical experience that is 10 times faster than Wi-Fi. Transfer speeds, up to several gigabits per second. The high-speed transmission performance provided by WiGig can not only greatly reduce the time for data transmission between devices, but also simplify the traditional wired connection method using transmission lines (cable), providing a simple...

Problems solved by technology

And because the WiGig wireless expansion base can only be paired with a single device, once it is paired or connected to any device, other devices can no longer establish a connection with it, and even cannot find this wireless expansion base

In addition, due to the high frequency of the 60Ghz radio signal, its path attenuation is more serious than that of the 2.5Ghz system, so the transmission distance of the WiGig signal (3.5Gbps) is only 15 feet within the line-of-sight range (Line-of-sight). Compared with the transmission distance of 160 feet provided by the current Bluetooth 4.0 technology, it is significantly shorter

The single-device connection and low transmission distance of WiGig mentioned above will make it difficult for users to search for or connect to the WiGig wireless expansion base in actual use.
