Understand the fundametnal principles used in creating a cellular communication network.
Gain a solid foundation for better understanding protocol specific network thoery like GSM and CDMA.

About This Course

Learn the fundamental concepts that every cellular network operator needs to know about cell phone architecture and functionality.   This course is tailored to students with little to no background in RF Engineering who want to learn the practical functions of how a cell phone network operates.



 This course covers fundamental principles used in wireless telecommunication including discussions about the history of cellular communications, radio frequency engineering, cell site planning, equipment components, and call processes.  By taking this course students will quickly grasp the same complicated subjects that are taught to military intelligence and law enforcement officers who work with cellular telecommunications in their respective duties.

This course is designed to be a beginner level class for students that are studying cellular protocol theory.  This class does not cover a specific cell phone protocol, rather it provides an overview of fundamental principles used in every type of cellular network architecture.  The topics discussed in this class are universal to all cell phone protocols and thus are necessary for those studying advanced protocol theory. 

This course is ideal for students who are either interested in RF engineering as a career or academic field, employees of wireless service providers, members of law enforcement or military, or professionals with a need to understand the basic workings of cellular technology.  The lessons taught in this course are extremely valuable to anyone who is going to study specific cellular protocols.  I recommend this course first to anyone interested in taking my more advanced courses in GSM, CDMA, or UMTS.

The course uses a teaching method and approach that was developed for teaching military and law enforcement officers.  It takes into account that most students do not have an engineering background.  No complex math or abstract principles are presented, and every concept is illustrated with in depth talking points.  

Course Instructor.

This course is presented by retired Army sergeant Josh Russell.  Josh is a SIGNAL Intelligence and military intelligence expert with a background in special operations (SOF).  

Basic Cellular Networks Operator Course


In this section I go over the course syllabus and talk briefly about the content of each individual lesson.

Radio History

Learn about the development of radio communication technology leading up to the invention of the first cellular telecommunication networks.

The First Cellular Concept

An overview of how the first cellular networks were designed and deployed.

Basic Cellular Architecture

An overview of cell phone tower design and how radio coverage from a tower is determined.

Network System Layers

This section describes a way to breakdown any cellular network protocol into 3 main categories that can be examined separately.  This enhances the students ability to absorb the technical aspects of cellular protocol theory.

Quiz 1

Check on learning lectures 2 through 5

Radio Frequency Channels

A discussion about the use of channelization in cellular networks. This includes multiple definitions of the work "channel" within the network system protocol.

Multiple Access

Every cell phone network strives to achieve a high customer capacity.  This lesson talks about how engineers design a cellular network so that it provides service to high numbers of customers while using very limited resources.


This section talks about how cell phones area able to transmit and receive signals simultaneously, allowing for cell phones to be mobile while also providing a quality user experience.

Quiz 2

Check on learning Lecture 6 through 8

Frequency & Wavelength

One of the basic principles of Radio Frequency Propagation.  We talk about the correlation between frequencies and their wavelengths and the implications this has on cellular telecommunication signals.

Frequency, Wavelength, Amplitude

This lesson on modulation talks about the formation of an electromagnetic wave and how engineers design a protocol to add information to those waves so that they can provide voice and data services over the air.


This section talks about how cell phones measure the strength of the signal transmitted by a cell phone tower.

Quiz 3

Check on learning lectures 9 through 11

Call Flow Processes Part 1

In this lesson we examine the procedural steps that are common in most cell phone networks when a call is made.

Call Processes Part 2 & Conclusion
Final Exam
You can view and review the lecture materials indefinitely, like an on-demand channel.
Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
