课程名称：新！CWNA无线网络管理员培训CWNA-109 课程概述：本课程将帮助您掌握参加CWNA-109考试所需的所有必要知识，另外，还将介绍为CWS CWT考试所需的更多主题，并为CWDP CWSP考试奠定坚实的基础。通过本课程，您将能够理解无线网络、相关标准及其操作原理，以及如何确保这些网络的安全。在学习过程中，建议按顺序完成课程内容，因为本课程是以连贯的方式构建的。 学习内容包括： 1. **无线技术基础**：学习不同的射频（RF）技术，包括波长、频率和幅度等。 2. **RF数学基础**：掌握RF数学的基本概念，理解术语如dBi、dBd、瓦特（watts）和毫瓦（milliwat）。 3. **天线理论**：深入了解不同类型天线及其工作原理，基础知识帮助进行天线计算。 4. **无线局域网（WLAN）标准与架构**：了解IEEE 802.11标准、无线拓扑、基本服务集（BSS）及架构组件。 5. **无线安全**：探讨无线安全问题、认证与加密方式，包括对称加密和非对称加密。 6. **网络协议**：学习动态主机配置协议（DHCP）、网络时间协议（NTP）及域名系统（DNS）在无线网络中的应用。 7. **站点调查与设计**：预测WLAN设计及其在语音、视频和数据应用中的应用，进行有效的预部署和后部署站点调查。 通过本课程的学习，您将对无线网络的各个方面有全面的理解，为后续的认证考试打下坚实的基础。
In this course you will learn all necessary topics for your CWNA-109 Exam. You will also learn more topics that you will need for your CWS CWT exams and you will gain immense knowledge for the fundamentals for your CWDP CWSP exams. Thanks to this course, you will be able to understand wireless networks, their standards, how they operate and how you can secure them. When you are learning throughout this course, it will be a great idea to follow without skipping any lessons as the course was built in a sequencial manner. You will start your learning experince by going over different RF Technologies such as Wavelength, Frequency, Amplitude etc. Then you will start learning the RF mathematics which is an essential part of understanding what certain terms mean such as dBi, dBd, watts, milliwats. After that we will start learning about different antennas and we will have a better understanding as we already have the necessary knowledge on rf mathematics and an essential part of antenna calculations.RF CharacteristicsFrequencyWavelength and AmplitudeRF Spectrum and ReflectionRefraction and MultipathScattering and AbsorptionFree Path Loss - Line of Sight and Fresnel ZoneRF MathematicsWatt - Milliwatt and Decibel (dB)RF Mathematics and RulesWhat is dBi and dBdRSSI and SNREIRP Effective Isotropic Radiated PowerRF Antenna CharacteristicsRF Antenna Principles and PolarizationMagnetic Field and DensityAntenna Types and Omnidirectional AntennasDirectional AntennasAntenna Connectors Attenuators and AmplifiersLightning Arrestors and SplittersWLAN Industry OrganizationsIEEE and WiFi AllianceRegulatory Bodies FCC and ETSISpread Spectrum TechnologiesSpread Spectrum OverviewSpread Spectrum FHSS and DSSSSpread Spectrum DSSS Deep DiveDSSS Continues and OFDMIEEE 802.11 Bands and Standards ISM and UNII BandsChannel Widths and Channel OverlapsChannel Aggregation80211 Standards Overview80211b and 80211g Standards80211a and 80211n Standards80211ac Standard80211n 80211ac BenefitsSpatial Multiplexing (SM)Transmit Beamforming (TxBF) and Maximal Ratio Combining (MRC)Multiple Input Multiple Output (MIMO)Coexistence of Standards RTS and CTSWLAN Architecture and ComponentsWireless Topologies and AdHoc NetworksBasic Service Set (BSS) Infrastructure modeSSID Service Set IdentifierWireless BridgesMesh APs and ComponentsHow Wireless Frames Transmit80211 Frame FormatWireless Management FramesWireless Control and Data FramesWireless Lan ControllerWLAN Network Security Wireless Security Issues AuthenticationEncryption - Symmetric and AsymmetricOpen Authentication and WEP AuthenticationTKIP WPA and AES EncryptionMAC Filter and SSID Hiding (Cloaking)EAP Overview8021X OverviewEncryption KeysWPA and WPA2 AuthenticationMiscellaneous WLAN Protocols Dynamic Host Configuration Protocol DHCPDHCP for IPv6NTP and DNS For Wireless NetworksIPv6 AddressingSite Survey and WLAN DesignPredictive WLAN Design and Voice ApplicationsPredictive WLAN Design and Video ApplicationsPredictive WLAN Design and Data ApplicationsPre Deployment Passive Site Survey and Interference SourcesPre Deployment Active Site Survey - AP On A Stick Pre Deployment Active Site Survey Part 2Post Deployment Site Survey
