Experimental device for heterogeneous wireless network having strong bandwidth difference characteristic

Abstract

The invention discloses an experimental device for a heterogeneous wireless network having a strong bandwidth difference characteristic. The experimental device is applicable to a 2.4GHz wireless network, a 400MHz wireless network, a 5.8GHz wireless network, a code division multiple access (CDMA) network and a very high frequency (VHF) range wireless network. The experimental device comprises a general computer, software radio equipment, a CDMA router and a VHF radio station simulator. The general computer is connected with the software radio equipment for establishing the 2.4GHz wireless network, the 400MHz wireless network and the 5.8GHz wireless network, the software radio equipment comprises front-end hardware equipment and a rear-end software module, the rear-end software module runsin the general computer, the front-end hardware equipment is connected with the rear-end software module by an universal serial bus 2.0 (USB2.0) technology. The general computer is connected with theCDMA network router for establishing the CDMA network. The general computer is connected with the VHF radio station simulator for establishing the VHF range wireless network. The experimental device ensures rich teaching contents and open experimental environment, and provides convenience for students to study and research various heterogeneous networks.

Description

technical field [0001] The present invention relates to a teaching experiment device, in particular to a teaching experiment device built on the basis of software radio technology for 5 heterogeneous wireless networks with large bandwidth differences of 400MHz, 5.8GHz, 2.4GHz, CDMA and VHF frequency bands. Background technique [0002] With the development of wireless communication technology and the promotion of various applications, each wireless frequency band can be used for wireless communication. The wireless networks corresponding to different frequency bands have large bandwidth differences, and also present different structures and characteristics. For example, the bandwidth of a 400MHz wireless network is often hundreds of Kbit / s, while the bandwidth of a 2.4GHz wireless network can reach tens of Mbit / s. Building a device that efficiently connects these heterogeneous networks with strong bandwidth differences becomes a network A need for teaching and even network r...
