Accessing and networking method for wireless digital communication

Abstract

A network access method used for the wireless digital communication, a wireless communication system comprises a number of wireless communication module, and each wireless communication module has its own baseband controller and radio transceiver, and the independent local clock, and it is characterized by: the base station comprises one or more above wireless communication modules, each wireless communication module occupying a band, and the band is divided into a management channel and several business channels; in addition, the single wireless communication module becomes the user terminal, and the user terminal can work not only in the management channel, also in the business channel, through frequency hopping to realize, and the wireless communication module of the base station sends and receives the information through the timeslot of the local clock definition, which processes wireless communication with one or more user terminals, and it has the advantages of high flexibility, scalability and portability, and it can be used in personal communication, LAN communication, industrial control, and other fields.

Description

Technical field [0001] The invention relates to a networking method for wireless digital communication in a wireless local area network. Background technique [0002] A wireless local area network (WLAN) is a new method that uses wireless technology to replace the previous wired wiring method to form a local area network, and can provide all the functions of a traditional wired local area network. Wireless local area network has the advantages of convenient installation, flexible use, economy and easy expansion, so it is used in more and more fields. [0003] As the cost of radio communication modules decreases, more and more wireless communication technologies integrate multiple radio communication modules into a single communication device and use this as the basic unit of a wireless local area network, thereby increasing the capacity of the entire system. [0004] Among the existing technologies, GSM, GPRS, CDMA, etc., as the mainstream of wireless communication, have been wid...

AI Technical Summary

Problems solved by technology

But as a small local area network, similar wireless communication modules and networking modes are too complicated and expensive

And for the Chinese people, the various technologies mentioned above are closed, and it is difficult for us to modify them to meet the needs of our business

[0005] For example, the Chinese patent No. 00808585.4 "Communication Protocol for Packet Data in Mesh Topology Wireless Networks", which is in a type of wireless packet radio mesh topology communication system, said type has A plurality of interconnected nodes with a line-of-sight layout, a method of communication between nodes comprising the steps of: dividing time into synchronous frames of known length; in each frame, providing time slots for control information, thereby Provide synchronous control channels; between communication nodes, use the control information at each communication node to schedule asynchronous data transmission or reception between the control channel time slots, thereby providing data channels. Its advantages are: (1) regional The signal is highly covered, (2) the bandwidth capacity of the network is increased, (3) multi-routing leads to routing diversity and load balancing, the defect is that compared with the mesh structure disclosed in the literature, one node in the website structure can communicate with multiple nodes , and there is no unified upper-level control center, the classification is not obvious, its communication scheduling is easy to cause confusion, its complexity is relatively high, the cost of implementation is also higher, debugging is relatively difficult during the implementation process, and reliability decreases
