Description
Technical field
The present invention relates to portable terminal and its implementation of a kind of Wimax of comprising wireless access function and Bluetooth wireless transmission function, relate in particular to system and implementation method that a kind of Wimax of elimination wireless access technology and Bluetooth RF are disturbed mutually.
Background technology
Along with the development of mobile communication technology with popularize, people require more and more higher to the mobile communication data performance of services, also emerged the higher air interface technologies of a lot of link rates, such as the Wimax technology that adds the 3G standard ranks recently is the micro-wave access global inter communication technology, and its peak value downstream rate has reached 10Mbps; Up-to-date standard in the point-to-point transmission Bluetooth technology is that the wireless transmission rate under the SIG bluetooth 2.0+EDR can be supported 3Mbps, and the wireless technology of these different application occasions also progressively is integrated on the same portable terminal.Because the frequency range (2402MHz-2480MHz) that Bluetooth technology is used is close with Wimax technology frequency range (2.3GHz-2.4GHz, 2.5GHz-2.7GHz) commonly used, the problem that the radio frequency coexistence is disturbed unavoidably occurs.While is along with the release of two kinds of technology new standards, described Wimax technology radio frequency maximum transmission power can reach 30dBm, described Bluetooth technology radio frequency maximum transmission power can reach 20dBm, thereby makes that the radio frequency mutual interference problem of two kinds of communication modes is more serious.When two kinds of business interfere with each other when serious, make two kinds of professional other transmission qualities that divide decline to a great extent, cause a certain communication blocking or interruption easily, and then influence the experience of mobile phone users.Equally, Wifi (the Wireless Fidelity: Wireless Fidelity) technology that uses always in the wireless access technology, though its radio-frequency emission power is less than the Wimax technology, but because its frequency range of using is 2.4GHz～2.4835GHz, the frequency range of using with Bluetooth technology overlaps substantially, there are the problems referred to above equally in portable terminal for while bluetooth enable and Wifi access function.
Support simultaneously in the prior art that the portable terminal of Wimax technology and Bluetooth technology occurs, the main solution that two kinds of communication modes of present solution are sent out radio frequency mutual interference altogether is the corresponding radio-frequency antenna distance that increases two kinds of communication modes, thereby reduces the radiated interference energy; Though this solution simple and feasible, but in order to reduce the radiated interference energy of two kinds of communication mode work, need to increase the corresponding radio-frequency antenna distance of these two kinds of communication modes, thereby caused the portable terminal size all bigger than normal relatively, make portable relatively poorly, and this solution can not thoroughly be eliminated Wimax technology and the Bluetooth technology radio frequency phenomenon of mutual interference mutually.As seen, prior art awaits further developing.
