本文将从以下几个方面入手,着重阐述无线网络解决方案之直序列扩频(DSSS)与跳频扩频(FHSS)技术的不同之处。同时本文也将顺便回答如下几个问题:1、为什么直序列扩频系统具有较高的抗干扰能力?2、为什么直序列扩频系统比跳频扩频系统更适用于大型百货商店和工业环境?3、为什么直序列扩频具有比较高的有效数据流量?4、为什么直序列扩频系统与跳频扩频系统相比有更大范围覆盖能力?5、为什么直序列扩频系统相当于跳频扩频系统每Mbit/s的成本更低?6、为什么直序列扩频系统比跳频扩频系统有更好的功耗效率?
This article starts with the following sections, highlighting the differences between DSSS and FHSS for wireless network solutions. At the same time this article will also answer the following questions by the way: 1, why the direct sequence spread spectrum system has a high anti-interference ability? 2, why the direct sequence spread spectrum system is more suitable than the frequency hopping spread spectrum system for large department stores and industrial environments Why direct sequence spread spectrum has a relatively high effective data flow? 4, why direct sequence spread spectrum systems and frequency hopping spread spectrum systems have a wider range of coverage? 5, the direct sequence spread spectrum system is equivalent to the jump Frequency spread spectrum system per Mbit / s lower cost? 6, why direct sequence spread spectrum system has better power efficiency than frequency hopping spread spectrum system?
