Wireless Telecommunications is a comprehensive course on wireless, including radio fundamentals, cellular and mobile telecommunications, LTE, 5G, Wi-Fi 6 (802.11ax) and more. Included in TCO CTNS, CTA and CTSME Telecommunications Certification Packages: https://www.teracomtraining.com/certi...

Topics: Mobile Network Fundamentals • Cellular Principles • Digitized Voice over Radio • Mobile Internet • FDMA, TDMA, CDMA and OFDM • 4G LTE and OFDMA • 5G: New Spectrum, Ultra-Broadband and IoT • Wi-Fi 6 802.11ax • Communication Satellites

Wireless Telecommunications is a comprehensive up-to-date course on cellular plus Wi-Fi and satellites for non-engineering professionals. Taking this course, you will develop a solid understanding of the fundamental principles of radio, mobility and cellular, network components and operation, digital radio, mobile phone calls and mobile Internet access, spectrum-sharing technologies like OFDM, and LTE and 5G. In addition, you will get up to speed on the components, operation and latest standards for Wi-Fi, and the essentials of satellite communications.

We'll cut through the jargon to demystify wireless, explaining the fundamentals of cellular and mobility, the buzzwords, the network, technologies and generations, the underlying ideas, and how it all works together... in plain English.

Course Overview

We begin with basic concepts and terminology involved in mobile networks, including base stations and transceivers, mobile switches and backhaul, handoffs, cellular radio concepts and digital radio concepts.

You'll understand how a phone call connects from a cell phone to a landline, and the different methods of allowing other devices to use a smartphone's mobile Internet connection.

Without bogging down on details, we'll review spectrum-sharing technologies: FDMA for first generation; 2G GSM/TDMA, 3G CDMA and 4G and 5G OFDM.

We'll take some time to understand how modems represent bits on subcarriers, and how OFDMA is used in 4G and 5G to dynamically assign subcarrier(s) to users.

This is followed with Wi-Fi, or more precisely, 802.11 wireless LANs: the system components, frequency bands, bitrates and coverage for all of the versions up to Wi-Fi 6 which is 802.11ax, the first Wi-Fi to implement full-duplex communications with multiple simultaneous devices using OFDMA and a theoretical 9.6 Gb/s. We'll also cover WPA-2 and WPA-3 security.

The course is completed with communications satellites, in Geosynchronous Earth Orbit and Low Earth Orbit, including Iridium Next and Starlink.


What You Will Learn

You'll gain a solid understanding of the key principles of wireless and mobile networks:
• Radio fundamentals
• Mobile network components and operation
• Coverage, capacity and mobility
• Why cellular radio systems are used
• Registration and handoffs
• Digitized voice over radio for PSTN phone calls
• Mobile Internet: "Data Plan"
• Cellular technologies: FDMA, TDMA, CDMA, OFDM
• 4G LTE and OFDMA
• 5G: new spectrum, more b/s, ultra-broadband and IoT
• Wi-Fi: 802.11 wireless LANs, Wi-Fi 6 / 802.11ax, Wi-Fi security
• GEO and LEO satellite communications
• Starlink’s service model


Learning Objectives

On completion of this course, you will be able to:
• Describe the basic concepts of a mobile communication system, identifying the principal components, the objectives of coverage, capacity and mobility, and the operation including registration and handoffs.
• Explain what “cellular” means and why radio systems are designed as cellular systems.
• Explain how digital cellular can be used for what used to be called “data” (now basically Internet access), using a phone as a tethered modem to connect a computer for Internet access, using a phone as a Wi-Fi hotspot for other computers, or of course surfing the web and using apps directly from a smartphone.
• Explain the principles and describe the operation of the different spectrum-sharing technologies: FDMA, TDMA, CDMA and OFDM.
• Define the term subcarrier, how subcarriers are used, and OFDMA.
• Identify the spectrum 5G will be deployed on and use cases for each.
• Explain the basics of 802.11 wireless LANs, Wi-Fi and hotspots and compare and contrast that to cellular radio.
• Describe the two basic strategies for communication satellites and the pros and cons of each.
