Control information and service separate layered isomerism millimeter wave wireless local area network framework

Abstract

The invention discloses a control information and service separate layered isomerism millimeter wave wireless local area network framework which is characterized in that a 2.4 Ghz / 5 Ghz omni-direction control subnet is used as a foundation, a plurality of 60 Ghz orientation service subnets are borne on the foundation, the control subnet comprises an access point and a plurality of users, the access point and the users are provided with intelligent antennas which are antenna arrays with beam forming capacity, and the antenna arrays can form certain antenna beams which can achieve orientation sending and receiving. The framework has the advantages that control information and service are separated, 60 Ghz millimeter wave high-speed service data transmission is achieved, network service capacity is greatly improved, meanwhile, basic operation of the whole network is guaranteed through omni-direction control information of 2.4 Ghz / 5 Ghz frequency bands is guaranteed, unnecessary energy loss caused by high-frequency-band transmission is avoided, and joint optimization of energy efficiency and spectrum resources is achieved finally.

Description

technical field [0001] The invention relates to a wireless local area network architecture, in particular to a layered heterogeneous millimeter wave wireless local area network architecture in which control information and services are separated, and belongs to the technical field of wireless networks. Background technique [0002] The progress of wireless communication technology is always chasing the pace of application demand growth. When IEEE802.11n products that can provide a net rate of hundreds of megabytes are widely used on various handheld terminals and have become standard configuration components of terminal equipment, applications such as wireless high-definition video transmission, mass downloads, and wireless Gigabit Ethernet Data transmission rate requirements have been as high as 1-3Gbps. At the same time, the shortage of wireless spectrum resources seriously restricts the further improvement of terminal speed. For this reason, many countries such as Europ...

Problems solved by technology

If the basic coverage of the network is still achieved in the traditional way, it is expensive and almost impossible to achieve

Therefore, it is not possible to simply copy the 60GHz millimeter wave from the current wireless local area network or wireless personal area network. It is urgent to find an energy-efficient networking architecture that can not only realize the directional transmission of 60Ghz high-speed services, but also minimize unnecessary energy. consume
