We begin with the terminology and basic concepts such as cellular radio, digital radio, base stations and transceivers, handoffs, mobile switches and backhaul. Then, we review spectrum-sharing technologies and their variations in chronological order: FDMA for first generation, GSM/TDMA for second generation, and CDMA for third generation. We'll explain the OFDMA spectrum-sharing method for 4G LTE and 5G used to dynamically assign subcarrier(s) to users and how bits are represented on subcarriers by modems. This is followed by a lesson on Wi-Fi, or more specifically, 802.11 wireless LANs and Wi-Fi 6, and a lesson on satellite communications including Iridium Next and Starlink. On completion, you will be able to draw a model of a cellular wireless telecommunications network, identify all of its components and technologies from handset to mobile switch, and explain the characteristics and operation of FDMA, TDMA, CDMA and OFDMA.

Next, we'll cover Plain Ordinary Telephone Service and aspects of telephony including twisted pair, the voiceband, analog, supervision and signaling including DTMF. The course finishes with an explanation of the SS7 control system for the telephone network used in the US and Canada.

    Course 2212 OSI Layers and Protocol Stacks free preview
    Course L2212 OSI Layers and Protocol Stacks

    OSI Model • Layers • Protocols • Standards • Protocol Stacks • FedEx Analogy

    14 interactive multipart lessons, multiple-choice exam and certificate. Produced 2020.

    This course is the first in the set of 4 "networking courses" in the CTNS, Certified Telecommunications Network Specialist package. It establishes a framework, used for all of the subsequent discussions, which is the OSI 7-Layer Reference Model. This framework allows us to organize the many functions performed so that we can discuss the issues separately. It defines groups of functions called layers. To begin, we'll define "protocol" in comparison to a standard. Next, we'll define "layer" and provide an overview of each of the seven layers, its name, purpose and function; and how a layered architecture operates. Then, we'll go back in more detail with one lesson for each layer, examining the functions to be performed, and giving examples of where and how the various protocols are used in the implementation of particular layers. The result is one protocol on top of another on top of another, creating a protocol stack, to fulfill the required functions. To make this easier to understand, we finish with the famous FedEx Analogy which illustrates the concepts using a company-to-company communication, and an analogy of Babushka dolls which illustrate how, at the bits level, the protocol headers are nested. Upon completion of this course, you'll be able to define a protocol as differentiate from a standard, explain why we require a layered architecture, name the 7 layers of the OSI model describing the purpose and functions of each, explain how a protocol stack works and where protocol headers are located.

    Course 2211 LANs, VLANs, Wireless and Optical Ethernet free preview

    Course L2211 LANs, VLANs, Wireless and Optical Ethernet – which could also be titled "Layer 2".

    Layer 2 Switches • VLANs • 1000BASE-T • Ethernet on Copper • Power over Ethernet • MAC Addresses • MAC Frames • Office Wiring Plan • Cables Categories • Wireless Ethernet (Wi-Fi) • Ethernet in the Core, MANs and PONs • Optical Ethernet • Fiber Types • Field Installation • SFP Transceivers

    7 interactive multipart lessons, multiple-choice exam and certificate. Produced 2020.

    This course is all about Ethernet which is the equivalent of physically connecting two devices. We cover the fundamentals, the equipment and implementations including wireless and fiber, twisted-pair copper cables, MANs, PONs, in a building and in the network core. We'll begin by defining "broadcast domain" and its first implementation over a bus cable. We'll explain LAN interfaces, how each has a hard-coded MAC address, and, since all stations in a broadcast domain receive all MAC frames, how the address field is used to determine who a MAC frame is for. We'll learn how the bus in now inside the Ethernet switch, also called a LAN switch or Layer 2 switch, how the LAN switch knows the MAC address for the stations, and how the MAC frames are forwarded by the LAN switch to one or more stations. You'll learn how broadcast domains defined in software are called VLANs and can be used to separate traffic by work area and device type at the enterprise level or by customer at the carrier level. Then we'll cover the IEEE 802.3 standards and the evolution of Ethernet from 10BASE-5 to 1000BASE-T on LAN cables and the TIA-568 cable categories, and Wi-Fi certification and 802.11 wireless LANs. We'll finish with a lesson on Optical Ethernet which is Ethernet on fiber and the basis of the telecom network today. You'll learn about how bits are represented, underground installation of fiber cables and fiber splicing used to connect bulk fiber and equipment. On completion, you will be able to define a broadcast domain, explain Ethernet and the 802 standards, MAC addresses, LANs, VLANs, and Optical Ethernet, the jargon and buzzwords, the underlying ideas, and how it all works together to move data between two devices in the same broadcast domain.

    Course 2213 IP Networks, Routers and Addresses free preview

    Course L2213 IP Networks, Routers and Addresses – which could also be titled "Layer 3".

    IP Packets • Networks • Routers • Static and Dynamic Addresses • Public and Private Addresses • DHCP • NAT • IPv6
    11 interactive multipart lessons, multiple-choice exam and certificate. Produced 2020.
    This is a comprehensive course on the Network Layer, Layer 3 of the OSI Model, concentrating on IP packet networks. We begin with the two basic principles of packet networks: bandwidth on demand, also known as overbooking or statistical multiplexing; and packet-switching, also known as packet forwarding or routing. We'll understand how packet switching is used by routers to implement the network by relaying packets between circuits, how routers are a control point for security on the network, the content of a routing table, and the term "Customer Edge". Then we'll cover IP addresses: IPv4 address classes, static addresses, dynamic addresses and DHCP, dotted-decimal notation, public addresses, private addresses and Network Address Translation, plus an overview of IPv6, IPv6 address allocation and assignment. On completion of this course, you will be able to define bandwidth on demand and its advantages, what a router does, the basic structure of a routing table, where routers are located, define the IPv4 address structure and dotted-decimal notation, explain how both static and dynamic addresses are assigned using DHCP, what private addresses are and how they are interfaced to the public IP network, the structure, allocation and assignment of IPv6 addresses and end up understanding how IPv6 subnets will be assigned to broadcast domains and 18 billion billion addresses per residence.

    Course 2214 MPLS and Carrier Networks free preview

    Course L2214 MPLS and Carrier Networks

    Carrier Packet Networks • Technologies • SLAs • CoS • MPLS • MPLS VPNs • Integration & Aggregation
    11 interactive multipart lessons, multiple-choice exam and certificate. Produced 2020.
    This is an up-to-date and comprehensive course devoted to the structure, components and operation of carrier packet networks, built and operated by companies such as AT&T, how they are implemented, how customers connect and the services offered. The IP packet and routing story explained in the previous course will now be applied at the carrier network level by replacing dedicated lines with a bandwidth on demand service provided by a carrier between customer locations. Much of this course explains virtual circuits, a powerful tool used for traffic management, implemented with MPLS, and how MPLS can be used to implement convergence, offer differentiated services and aggregate traffic. The course is completed with a lesson on "MPLS service", and how that compares to Internet service. On completion of this course, you will understand carrier packet networks and service, be able to define the terms Customer Edge and Provider Edge, explain what a traffic profile is and how that relates to a Service Level Agreement, the purpose, components, terminology and operation of MPLS and MPLS for business customers, and how MPLS can be used to implement integration or convergence, aggregation and differentiated classes of service – what people mean when they say "MPLS service" and its pros and cons compared to Internet service.
