3.5G wireless broadband router

technical field

Background technique

With the continuous development of wireless Internet technology, the use of routers has become more and more frequent. A router is a device connected to various LANs and WANs in the Internet. It will automatically select and set routes according to the channel conditions, and send signals in the best path and in sequence. The router is the hub, the "traffic policeman" of the Internet. At present, routers have been widely used in all walks of life, and various products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet. The key difference between routing and switching is that switching occurs at layer two (data link layer) of the OSI reference model whereas routing occurs at layer three, the network layer. This difference determines that routing and switching need to use different control information in the process of moving information, so the two implement their respective functions in different ways. A router is used to connect multiple logically separated networks. The so-called logical network represents a separate network or a subnet. When data is transferred from one subnet to another, it is done through a router. Therefore, the router has the function of judging the network address and selecting the path. It can establish a flexible connection in a multi-network interconnection environment, and can connect various subnets with completely different data packets and media access methods. The router only accepts the source station or other Router information is an interconnected device at the network layer. It does not care about the hardware devices used by each subnet, but requires running software consistent with the network layer protocol. Routers are divided into local routers and remote routers. Local routers are used to connect network transmission media, such as optical fibers, coaxial cables, and twisted pairs; remote routers are used to connect remote transmission media and require corresponding equipment, such as telephone lines.
