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 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.
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).
In this section I go over the course syllabus and talk briefly about the content of each individual lesson.
Learn about the development of radio communication technology leading up to the invention of the first cellular telecommunication networks.
An overview of how the first cellular networks were designed and deployed.
An overview of cell phone tower design and how radio coverage from a tower is determined.
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.
Check on learning lectures 2 through 5
A discussion about the use of channelization in cellular networks. This includes multiple definitions of the work "channel" within the network system protocol.
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.
Check on learning Lecture 6 through 8
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.
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.

In this lesson we examine the procedural steps that are common in most cell phone networks when a call is made.
I retired from the US ARMY in 2011 after spending 12 years in Military Intelligence as a SIGINT and Electronic Warfare Operator. While I was on active duty my main focus was to use my knowledge of Radio Frequency Propagation and Cellular Communication to collect battlefield information and target acquisition. Through necessity I developed an expert level of knowledge about the practical functionality of cell phone networks.
In my UDEMY courses I use a curriculum to teach cellular network theory that I developed and used (and still use) to teach Military Intelligence Officers, Electronic Warfare Operators, and even Special Forces Green Berets, and Navy Seals.
