Description

200836519 IX. Description of the Invention: [Technical Field] The present invention relates to a multimode wireless network device, system and method, and more particularly to a architecture in a miAXC Wortchvide Interoperability for Microwave Access (Worldwide Interoperability for Microwave Access) architecture An MMAX wireless network device, system and method that have dual functions of a router and a relay station (Relay Stati〇n). • [Prior Art] Due to the increasing demand for electronic information devices and the need for real-time information transmission, mobile communication has become a necessary consideration for the general public to purchase electronic information devices. In the case of wireless network communication systems, the combination of RF technology and network technology allows users to connect to other network devices and transmit information over the wireless network without connecting to the physical network route. And can meet the needs of mobile Internet. The currently known mobile Internet technologies mainly include GPRS (General • Packet Radio Service), 3G (3rd Generation, 3rd Generation Mobile Communication System), WiFUMrdess Fidelity 'Wireless Compatibility Certificate, and WiMAX (w〇). Rklwide

Architecture such as Interoperability for Microwave Access, Worldwide Interoperability for Microwave Access. Among them, since GPRS and 3G are architectures under the Global System for Mobile Communications (GSM) architecture, there are disadvantages such as relatively slow transmission speed and relatively high cost of providing communication services. Relatively speaking, since WiFi and WiMAX are respectively structured under the Ethernet architecture, 200836519 can provide relatively fast network transmission speed and relatively low communication service cost. In the Fi-based architecture specified by the IEEE802.11b standard, it mainly provides short-range wireless transmission technology within a communication range of about 300 inches, so it is widely used in WLAN (^\%eless Local Area Network, wireless area). Network) in a wireless network device. The WiMAX architecture is based on the IEEE 802.16 family of standards (eg, IEEE 802.16-2004, IEEE 802.16e, and the still-developed IEEE 802.16j, etc.), which provides a communication range of up to 30 inches, so It is often targeted at applications that are part of the WAN (Mde Area Network). At present, WiFi and WMAX are generally regarded as complementary but not competing technologies, and are more likely to replace GPRS and 3G and become the mainstream technology for future mobile Internet access. In the current prior art, WiMAX and WiFi wireless network systems are still independent. See Figure 1, which is a typical example of a traditional WiMAX (or WiFi) wireless network system. A conventional WiMAX wireless network system usually includes a plurality of WMAX base stations 11, 12 to provide wireless network services, and each of the base stations ^, 12 provides a wireless signal strength range that includes a communication range m, 121. The wiMAXR mobile Internet device 13 located in the base station η communication range lu will be able to establish a connection with the base station 11 and enjoy the mobile Internet service. If the WiMAX mobile internet device 14 can receive signals from different base stations 11 and 12 at the same time, the mobile internet device 14 will automatically select the base station 12 with stronger signal stability to connect. In contrast, 7 200836519 耥If the WiMAX mobile Internet device 15 is located outside the communication range m and 121 of all the base stations 11 and 12, the mobile Internet device 15 will not be able to enjoy the actions provided by the base stations 11 and 12. Internet service. Therefore, in the prior art, WiMAX (or WiFi) system operators must set up base stations widely and in large numbers to provide sufficient signal coverage and stable communication quality. However, this will obviously keep the infrastructure costs of the system operators high, and indirectly hinder the popularity of WIMAX (or WiFi), and there is room for further improvement.
