Automatic CTNS Course Updates and Package Upgrades

In the constantly-evolving world of telecom, it is essential to keep training courses up to date.

The reason why so many people appreciate Teracom’s Online Courses and TCO Certification Packages is because they are based on Teracom’s instructor-led courses, with the selection of material, its order, timing and explanations tuned and refined in the classroom over the course of years, and constantly updated.

This also means that updates to instructor-led courses are subsequently reflected in online courses, keeping them up to date.

Following the major update to instructor-led Course 101 Broadband, Telecom, Datacom and Networking for Non-Engineers (Days 1 – 3 of BOOT CAMP) in 2020, updates to many online courses will be rolling out over the next months.

Certified Telecommunications Network Specialist (CTNS) is our most popular package of six online courses plus TCO Certification.

All six CTNS courses are being updated.  Update of Course 2201 The PSTN is complete.  A significant update to Course 2206 Wireless Telecommunications will be published in the next weeks.  Updates to the OSI Layers, Ethernet, IP and MPLS courses will follow.

All customers who have purchased the CTNS package, or any of the courses individually, will automatically receive the updates in their dashboard.

Stay tuned for an exciting announcement of an upgrade to the CTNS package, increasing the package from six courses to eight, with the inclusion of a brand new course #1 in the lineup “Introduction to Broadband Telecommunications” plus “Fundamentals of Voice over IP”.

The price of the CTNS package will increase when the number of courses increases from six to eight. Since all existing customers will automatically get the two new courses at no additional charge, you can beat the price increase by purchasing CTNS before the upgrade and get the two new courses, when they are released, for free!

Course 2231 Wireless Fundamentals
Lesson 1 Introduction and Radio Fundmentals

Enjoy this free sample video from CWA.

Course 2231 Wireless Fundamentals

Radio fundamentals • Spectrum • Digital radio • Modems and Modulation • Propagation, Penetration and Fading

Wireless Fundamentals is the first course in the CWA Certification Package. We begin with the basics: what radio is, how it’s organized and how and it’s used to communicate information.

We begin by understanding what radio actually is, and why we use it for communications. We’ll understand how radio frequencies are in the Gigahertz range, used within frequency bands measured in the Megahertz wide.

Then we will look at the spectrum, i.e. standardized bands of frequencies, how they are allocated and the need for licenses. You will learn which bands are used for what, from cordless phones to WiFi and cellular, including the new 700-MHz bands.

Next, we’ll understand how information is represented using radio. The first stop is a quick review of old-fashioned analog radio and TV, followed by what most systems use today: digital. We’ll spend some time understanding digital, how 1s and 0s are communicated by modems and familiarize you with jargon and buzzwords like QAM and QPSK.

We’ll finish off with radio transmission issues, including propagation, penetration and fading.

1. Radio Fundamentals
2. Wireless Spectrum and Radio Bands
3. Analog Radio
4. Digital Radio: How Modems Work
5. Propagation, Penetration and Fading

Tutorial: Mobile Operators, MVNOs and Roaming

From the new Telecom 101 Fifth Edition: 2020

9.7 Mobile Operators, MVNOs and Roaming

9.7.1 Mobile Network Operator

Mobile Network Operator (MNO) is the term usually used to refer to a facilities-based carrier, i.e. a company that owns base stations, a mobile switch, backhaul between them, and spectrum licenses, and sells services to the public… and to other carriers.

The MNO implements external links to other carriers for PSTN phone calls and for Internet traffic.

For PSTN phone calls, the MNO implements a fiber optic connection to a building traditionally called a Toll Center or Class 4 switching office. The termination of their fiber in that building is called a POP. It is their physical point of presence in the building.

Many other carriers have POPs in the building, including the ILEC, IXCs, CATV companies, other mobile carriers, and any other company that wants to connect phone calls to a phone on the MNO’s network.

The operator of the toll center, usually the ILEC, provides a switch in the Toll Center to switch phone calls from one carrier’s POP to a different carrier’s POP.

For Internet access, the MNO implements a fiber optic connection to one or more Internet Exchange buildings, where they pay the operator of the IX to route packets to other carriers with whom the MNO has established IP packet transit and peering arrangements.

9.7.2 Mobile Virtual Network Operator

Mobile Virtual Network Operator (MVNO) is the term used to refer to a non-facilities-based carrier… one that does not own the hardware or spectrum licenses or POPs.

Instead, the MVNO enters into a long-term contract with one or more facilities-based carriers to have them supply a “white label” service that the MVNO sells.

Typically the MVNO will develop a unique branding and sell smartphones and tablets to go along with its service.

When the MVNO deals exclusively with one carrier, the MVNO bill to the customer would be typically generated by the facilities-based carrier as a white-label service.

If the MVNO is very large and deals with multiple carriers, the MVNO may operate their own billing system, which is a significant investment.

The facilities-based carrier charges to the MVNO includes a volume-discount rate for IP addresses and Internet traffic, voice-minute airtime and switched access to the POP for PSTN phone calls.

The MVNO also has to pay for connectivity from the POP to other toll centers for “long-distance” connections, and the switched-access charge at the far end.

The rate plan the MVNO pays could be a mix of fixed-rate leases and usage-based billing.

Unless the MNO is obliged to sell capacity to MVNOs through regulations and tariffs, the nature of the plan is confidential business information.

9.7.3 Roaming

Roaming service is very similar to the service provided to MVNOs, in that it is the MNO that is providing the airlink, base stations, backhaul, mobile switch and connections to the PSTN and Internet.

In the case of roaming, the visitor uses their own phone, and billing is usage-based.

Roaming is an important feature for smaller players: they are facilities-based in selected cities, but to offer a national and international service to their customers, they must have roaming agreements in place with MNOs in other locations.

By denying roaming service to smaller or startup carriers, or charging an exorbitant price for roaming, an incumbent carrier can erect a barrier against competition.

In many countries, the right to roam and the wholesale cost of roaming is regulated to encourage competition.
