如今,在全球通信基础设施中,有许多通信系统和网络,可以根据不同的类别进行分组,例如:模拟和数字,有线(常规电话网络)或无线(无线电通信),固定(LAN,WAN)或移动(GSM,GPRS等),协议(TCP / IP,蓝牙,ZigBee等。

远程通信或电信的现在和未来经历了所用手段的技术发展。最先进的系统由于微波范围内的更高频率带宽以及具有高功率天线的卫星的即时全球覆盖而实现了更高的通信速度。此外,电信系统的技术进步也促进了其他技术和概念的发展和出现,例如GPS定位系统的发展,将日常物品互连到Internet的可能性(物联网(IoT),行业现代化(工业4.0)或计算机安全或网络安全的发展。

3.1.- 电源, 测量设备和配件

电子学实验设备是指在电子学实践环节中进行实验所需的一套仪器。设备的特点取决于所要配备的实验室的理论水平,无论是技术研究所、大学还是公司的研发部门。电子实验室最常用的设备,一方面是电学测量仪器,有万用表或多用表等设备,根据型号的不同,可以实现电流表、电压表、电容表、电阻表等多种测量功能。另一方面,电子实验室有分析信号的仪器,有示波器、频谱分析仪等电子设备。最后,电子实验室有电子器件来产生信号,可以是电源产生的功率信号,也可以是函数发生器等变频模拟信号。未来的实验室仪器仪表旨在将所有的测量和信号产生设备(电压表、电流表、频谱分析仪、函数发生器等)统一在一个多功能设备中,并与计算机连接(这种连...

3.2.- 理论-实用基础

电子学基础是旨在为学生分析和理解最常见的电子电路的一般工作原理和构成电子电路的电子元件的个别功能打下坚实基础的知识体系。在电子学这样的专业学科中,掌握良好的理论基础,是后续设计和开发复杂电子系统的必要步骤。由于电子学也是工科的一个分支,很多理论概念都有直接的实际应用,如果在理论课上结合相关的实际例子进行教学,就会大大促进电子学学生对概念的吸收。电子学基础涵盖的内容非常广泛,其中电子电路的分析不能错过(利用欧姆定律、基尔霍夫定律、Thevenin定理、叠加定理、将分析的电路转化为更简单的等效电路等方程和程序)、基本元件的研究(电阻、电感、电容、不同技术的晶体管、二极管、晶闸管、逻辑门等)。...

3.3.- 应用通讯

今天,电信的应用和用途很多,如远程信息和远程信息服务、移动通信或全球定位系统等。通信技术的发展,如卫星通信的发展、光纤的出现、媒体的数字化等,使电信扩展到日常生活的各个领域。这种技术上的拓展,使得覆盖面更广,沟通速度更快,人与人之间的交流方式也不同。电话通信经历了从固定电话网到高速移动网的显著发展。因此,从固定技术到GSM或第二代(2G)、GPRS(3G)和4G技术或协议,再到5G技术,都有一个演变过程。自从互联网出现,并在TCP/IP协议的基础上发展出不同的协议后,本地或短距离(LAN、WLAN、WPAN)和长距离(WAN)计算机网络呈指数级增长。在无线网络内,WiFi、Wimax、蓝...
