Cellular/Mobile Wireless 3
This is the third course in the series on mobile wireless cellular communications. This course (Part III) begins with one of the most important topics in mobile cellular networks today. Since RF spectrum, used by mobile operators, is quite limited, there has been a need for radio link technologies to operate more efficient.
The first section delves into the complex topic of how multiple antenna systems are used in mobile cellular networks, which is yet another way to increase data rates between the mobile and base station. This critical technology was introduced in enhanced 3G mobile networks, referred to as 3.5G, which is also used in Wireless LANs (WLANs) today. It has become the basis for the air interface design in both 4G Long-Term Evolution (LTE) and 5G Radio Access Networks (RANs), which is critical to providing ever-increasing data rates. It also forms the basis for other enhancements that provide greater user density, in higher population areas.
The second section focuses on the various Long Term Evolution (LTE) standards, including LTE-Advanced (LTE-A) and LTE-A Pro. Today, there are over five billion unique mobile subscribers, worldwide, with all generations of technologies combined (2G through 5G). And there over 10 billion overall subscriptions, worldwide, when cellular Internet of Things (IoT) devices are included. Growth in 4G-LTE subscriptions is expected to grow through 2022, when 5G is expected to have a huge impact on global market saturation.
Section three covers the advances in mobile cellular technology, focusing on the evolving core networks, and newer methods of connectivity to the RAN. This section also introduces the concept of Self-Organizing Networks (SON) that help to manage growth and allow operators to scale today’s cellular networks to meet demands. The concepts and implementation of small cells is also introduced, used to greatly increase network coverage and density.
Finally, section four describes the current developments in 5G cellular networking standards and the services they provide. This section will begin with an overview of the International Telecommunications Union – Radio (ITU-R) requirements, providing a thorough description of what a 5G network is, and what services it can provide. The course will then conclude with an in-depth look at some of the technologies that are part of 5G networks and interfaces between logical and physical components of the network.
