摘　　要：蓬勃发展的物联网应用需求中孕育了多种2.4 GHz无线通信协议,众多共存的无线协议既是物联网设备、平台互联互通的基础,也是通信系统干扰来源,导致通信效率降低。因此,2.4 GHz频段的干扰与共存技术成为行业内一个研究热点。本文介绍了Zigbee、蓝牙和Wi-Fi等无线通信技术及其抗干扰特性,通过分析共存环境的复杂性和关键性,简化仿真模型,提出了2.4 GHz频率共存的关键性能指标,讨论了如何保证2.4 GHz无线技术的共存性能,对物联网更广泛互联互通发展具有重要意义。The booming application requirements of the Internet of things call for a variety of 2.4 GHz wireless communication protocols.Many co-existing wireless protocols are not only the basis of the interconnection of devices and platforms of the Internet of things,but also the source of interference in the communication system,resulting in the reduction of communication efficiency.Therefore,the interference and coexistence technology of 2.4 GHz band has become a research hot topic in the industry.This paper introduces the wireless communication technologies such as Zigbee,Bluetooth and Wi-Fi and their anti-jamming characteristics.By analyzing the complexity and criticality of coexistence environment,simplifying the simulation model,this paper puts forward the key performance index of 2.4 GHz frequency coexistence,and discusses how to ensure the coexistence performance of 2.4 GHz wireless technology,which is of great significance to the wider development of the Internet of things.
