Download or read book Wireless 101 written by Eric Coll and published by Teracom Training Institute. This book was released on 2023-01-31 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless 101 delivers the core technical knowledge needed by anyone serious in the wireless business today. A great deal of Wireless 101 is devoted to mobile communications, because one of the great things about wireless is you can move around while communicating, and people are willing to pay cold hard cash for it. If you added up all of the industry associated with mobile communications: everything from selling handsets and providing customer service, all of the people who work for the carrier, the trucks they buy, people getting jobs as riggers installing equipment on towers, the insurance they have to pay for – the mobile communications industry shows up as part of the gross domestic product of every country in the world. Bluetooth and Wi-Fi are now an indispensable part of everyday life including in-building Internet access and connecting your phone to your car as soon as you get close to it. In July 2022, Starlink was delivering download rates bursting up towards 1 Gb/s to remote areas for $120 per month. This brings Broadband To The Remote Masses in one fell swoop, and will surely boost the quality of life and economic activity worldwide. So that’s covered too. Part 1: Wireless Fundamentals The first part of Wireless 101 is Wireless Fundamentals, five chapters that set the foundation, with radio fundamentals and spectrum, how modems are used to move bits, and radio penetration, propagation and fading. Part 2: Mobile Communications The second part of Wireless 101 is Mobile Communications, fourteen chapters on mobility and mobile communications from A-Z, beginning with the ideas of cellular radio, handoffs, how PSTN phone calls (“Voice minutes”) are implemented, and how Mobile Internet (“Data plan”) is implemented. We’ll explain the technologies: FDMA, TDMA, CDMA, OFDMA, the generations, and LTE and 5G New Radio, including millimeter-wave Ultra Broadband and low-bit-rate 5G services for IoT. Part 3: Fixed Wireless In the third part of Wireless 101, we’ll cover other radio systems, primarily fixed wireless, where the question of continuous communications while driving down the highway doesn’t come into play so much. We’ll cover Wi-Fi: wireless LANs, standards and security, Bluetooth, broadband wireless home Internet, point-to-point, Low-Power Wide-Area Networks, and finish with satellite communications and Starlink.

Download or read book Legacy Technology All About T1 written by Eric Coll and published by Teracom Training Institute. This book was released on 2023-02-09 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legacy Technology: All About T1 This module provides detailed information on the carrier system technology called T1. T1 used to be a principal subject of telecommunications courses, but is now relegated to the back of the book, as T1 is a technology running at 1.5 Mb/s on copper wires, replaced with Gigabit/s Optical Ethernet on fiber. That said, there are thousands of T1 circuits installed and in use, and some readers of this book have picked it precisely to learn about T1 because they have been tasked with supporting it, or auditing an existing installation. Power companies, the military and government still have T1s in place, along with T1s at big organizations that are no longer being used, but have been forgotten and are still being paid for each month... a small but appreciated part of any phone company’s revenue. This chapter on T1 also provides a very detailed explanation of synchronous Time-Division Multiplexing, framing and channels. Since the principles of operation of legacy SONET fiber-optic transmission systems are the same as T1, learning about T1 is also learning about SONET.

Download or read book The PSTN and Broadband on Copper written by Eric Coll and published by Teracom Training Institute. This book was released on 2023-02-09 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The PSTN and Broadband on Copper Before wireless and fiber, two copper wires were used for the physical access circuit for telephone and cable TV service in suburbs and cities. Today, these wires are also used to deliver broadband. In this module, we’ll understand how DSL broadband service runs on twisted pairs put in place for analog POTS telephone service; how cable modems move broadband on coaxial cable; and how both are delivered as fiber to the neighborhood then copper to the premise. To finish up, we’ll review digital on copper wires: LAN cables and T1s.

Download or read book The OSI Layers and Protocol Stacks written by Eric Coll and published by Teracom Training Institute. This book was released on 2023-02-09 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The OSI Layers and Protocol Stacks There are so many functions that must be performed to interoperate systems, a structure is required to organize the functions so that separate issues can be treated separately. We'll explore the most commonly-used structure, the ISO Open Systems Interconnection 7-Layer Reference Model. You'll learn what a layer is, the purpose of each layer, examples of protocols like TCP and IP used to implement layers, and gain a true understanding of how a protocol stack works for applications like web surfing and VoIP.

Download or read book Digital Media Voice Video Images Quantities Text written by Eric Coll and published by Teracom Training Institute. This book was released on 2023-02-09 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital Media: Voice, Video, Images, Quantities and Text The converged network carries all media: voice, video, text and images in packets. An essential first step is digitizing the media, representing it using 1s and 0s, to be carried in said packets. We’ll first understand analog vs. digital, how voice is digitized and reconstructed, the G.711 64 kb/s and AMR codec standards. The same principles apply to images and video in formats like jpg and mp4 video. We’ll make sure you are up to speed on binary and hexadecimal for quantities, and finish with ASCII and unicode for coding keystrokes and emojis.
