System based on distributed wireless fusion network

Abstract

The invention relates to a wireless network, the next-generation communication, the technology of cognitive radio and the technology of ad-hoc network, and especially relates to a system based on a distributed wireless fusion network. A to-be-solved technical problem is how to improve the utilization rate of spectrum resources. The system comprises a plurality of assembly system terminal nodes, and the terminal node of each system consists of a broadband wireless spectrum cognition detection unit, a cognition ad-hoc network protocol unit, and a network integration interface unit, wherein each unit transmits information in a mode of ad-hoc network. The beneficial effects of the invention are that the system can be cooperatively used with a user terminal of a mobile cellular network, and improves the use efficiency of wireless spectrum; the system is cooperatively used with various types of data collection terminals, forms various types of wireless monitoring networks, and increases the network access speed; the system is cooperatively used with a wireless sensing network, and the wireless sensing network provides network access spectrum resources; the system is cooperatively used with a future 4G network user terminal; the system can be used independently, and serves as a 3G or 4G network user terminal.

Description

technical field [0001] The present invention relates to wireless network, next-generation communication, cognitive radio technology, ad hoc network technology, and in particular to a distributed wireless fusion network system. Background technique [0002] With the rapid development of wireless communication technologies, spectrum resources, especially spectrum resources below 2.5 GHz, are becoming more and more scarce. Due to the emergence of wireless local area network technology and wireless personal area network technology, more and more people access the Internet and telecommunication network in a wireless way through these technologies. Most of these technologies use unlicensed frequency bands to work, which makes these frequency bands tend to be saturated; but other licensed frequency bands (such as radio and television service frequency bands) require certain protection from the telecommunications network to avoid interference. This leads to very low utilization eff...

Problems solved by technology

Most of these technologies use unlicensed frequency bands to work, which makes these frequency bands tend to be saturated; but other licensed frequency bands (such as radio and television service frequency bands) require certain protection from the telecommunications network to avoid interference with them

This leads to very inefficient use of these dedicated frequency bands, and it is precisely these authorized frequency bands still occupy a large part of the spectrum resources, which invisibly causes a huge waste of spectrum resources
