Network system for sending and receiving various wireless network signals

The present invention relates to a network system for transmitting and receiving various wireless network signals, especially to a network system for transmitting and receiving wireless network signals. The wireless communication protocol used is decoded and converted, and the wired packet information to be transmitted is converted and encoded according to the stored encoding rules of various wireless network communication protocols, and then sent out in sequence. Therefore, The network system can exchange packet information wirelessly with any wireless network card using any wireless network communication protocol.

In the last ten years, the design of computer products has become more and more in line with the needs of humanization. In addition to reducing the size and ergonomics theory has been widely used in computer products, it can improve the transmission speed between computer products and peripheral equipment, and eliminate the interconnection between them. Cable arrangement has also become an important research topic for designers and manufacturers of various computer products and their peripheral equipment. Since the so-called computer standard (PC95, PC98, PC2000) was launched by the American businessman Microsoft (Microsoft) in 1995, wireless devices have become a standard computer equipment, and then the American businessman Microsoft (Microsoft) launched the Windows 95 operating system, It began to give desktop computers more possibilities in use, such as: support for multimedia devices, support for network functions, plug-and-play functions, etc., and became a standard function followed by the industry. Since then, the infrared transmission function has also been popularized on peripheral devices of computers. Since infrared transmission is directional, and it cannot work when the ambient light is insufficient (covering the fluorescent lamp with hands) or the device is too far away (3-5 meters), therefore, in recent years, many research units have aimed at this. Design a more advanced wireless network communication protocol in order to effectively improve many problems in infrared transmission.

In today's network systems that can send and receive wireless network signals, the communication methods of the network signals can be roughly divided into the following three types according to the specifications of the wireless communication protocols used:

(1) IEEE 802.11B: It is the IEEE 802 series of standards, formulated by the International Institute of Engineers (IEEE), using Direct Sequence technology (Direct Sequence), defining the Local Area Network (Local Area Network) to use wireless transmission for wireless network connections, and to transmit information Therefore, the IEEE 802.11 protocol is the wireless local area network protocol. The local area network signal defined by this protocol can be used within a distance of up to 100 meters indoors and about 300 meters outdoors, and has a very wide range for the number of connected devices. The use of space, the transmission speed that can be used in this protocol is about the current 100Base Ethernet.

(2) Bluetooth technology (Bluetooth): At the beginning of 1998, a wireless communication protocol jointly developed by well-known manufacturers such as 3COM, Nokia, Ericsson, Motorola, IBM, Microsoft and Sun, which uses frequency hopping technology (Frequency Hopping) , as a transmission medium between computers and peripheral equipment, its biggest advantage is that it overcomes the limitations of distance and the number of connectable devices, so it can still be used as a communication medium between mobile phones and computers, mobile phones and hands-free handsets, and various information appliances in the future. , a medium for wireless transmission of information, and even general household appliances such as TVs, air conditioners, stereos, and electric lights can also be used as a medium for wireless control.

(3) Home RF (Home RF) technology: frequency hopping technology (Frequency Hopping), its main purpose is to enable network appliances to use radio frequency signals for wireless network connections to transmit information and allow them to operate at 2.4GHZ Under the environment, it can transmit information of up to 1 megabit per second. Its biggest advantage is that it overcomes the limitations of bandwidth and the number of connectable devices. Therefore, many operators also use it in mobile phones and computers, mobile phones and hands-free handsets and Various information appliances are used as a medium for wireless transmission of information.

Although IEEE 802.11 has the advantages of longer signal distance, more storage devices, and faster transmission speed than Bluetooth technology and home radio frequency technology, Bluetooth technology and home radio frequency technology have the characteristics of crossing various fields of use and can be used for home appliances, computers and Due to the advantages of computer peripheral equipment and even mobile phones, the designers and manufacturers of various products now apply various wireless communication protocols to various wireless information appliances, computers, peripheral equipment and products according to their actual needs. on the mobile phone. In addition, since each wireless communication protocol uses the 2.4GHz ISM (Industrial Scientific Medical) channel, various products installed with various wireless communication protocols mainly use a wireless network set on it when connecting to the Internet. The card transmits wireless packet information according to the wireless communication protocol used. When a corresponding wireless network signal transceiver set on the wired network receives the packet information, it can use the network application program (Application) installed on it to ), perform routing (routing) and bridging (bridging) functions, and convert between wireless packet information and wired packet information, and provide path selection and address translation (Net Address Transfer, NET for short) and other functions.

However, in the aforementioned network applications that are currently on the market, they only have the function of receiving wireless packet information using the IEEE 802.11B protocol, or have the function of receiving wireless packet information using household radio frequency technology and Bluetooth technology, and cannot simultaneously receive the wireless packet information using the IEEE 802.11B protocol. 802.11B protocol, bluetooth technology and home radio frequency technology and other functions of wireless packet information, and it is impossible to convert the packet information of different wireless communication protocols. This incompatibility makes these devices have the function of network connection The information products of the company cannot be applied to network systems of other wireless communication protocols as expected, so that these information products have not been widely favored by consumers, but have gradually become popular in ordinary families and organizations.
