Broadband and narrowband integrated communication device and system

Abstract

The invention provides broadband and narrowband integrated communication equipment and system. The broadband and narrowband integrated communication device comprises a narrowband communication module,a broadband communication module and a core control module, wherein the core control module consists of a transceiving scheduling module, a routing control module and a user access module. The narrowband communication module is used for realizing narrowband service; the broadband communication module is used for realizing broadband service; and the core control module is used for realizing the loading of the operating system, the control of the broadband communication module and the narrowband communication module and the operation task of an ad hoc network protocol, and providing a user interface. The broadband communication module and the narrow-band communication module can meet the transmission requirements of broadband service and narrow-band service respectively, and also can complete the construction of a self-organizing network in a severe communication environment through the narrow-band communication module, thereby enlarging the network coverage as much as possible. Meanwhile, the cooperative scheduling of the broadband communication module and the narrowband communication module can be flexibly used for providing the wireless communication service under the self-organizing network, wherein the bandwidth of the wireless communication service is as high as possible and robust.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a communication system integrating broadband and narrowband. Background technique [0002] The wireless ad hoc network is a multi-hop mobility peer-to-peer network composed of several nodes, using wireless communication, and dynamic networking. Its purpose is to transmit data streams with quality of service requirements through dynamic routing and mobility management techniques. Generally, nodes do not need fixed equipment support, and each node forms a network by itself; when a node wants to communicate with nodes outside its coverage range, multi-hop forwarding of intermediate nodes is required. Different from multi-hop in fixed network, multi-hop routing in wireless ad-hoc network is completed by common network nodes, not by dedicated routing equipment (such as router). This network form breaks through the geographical limitations of traditional wireless netwo...

Problems solved by technology

[0004] Purpose of the invention: The present invention aims to solve the problem that there is a contradiction between high bandwidth and high availability in a wireless ad hoc network, and that the broadband communication module is susceptible to interference in complex scenarios, and proposes a broadband and narrowband integrated The narrowband communication module has relatively higher anti-interference ability and can provide longer-distance communication coverage. It can provide communication services and networks with relatively short bandwidth and relatively low transmission rate. Situation awareness and complex scene networking services, the system proposed by the present invention realizes the cooperative work of the broadband communication module and the narrowband communication module, making full use of the advantages of both
