Open RAN Explained

A pioneering outline of the concepts that enhance 5G capabilities to revolutionize the telecommunications industry.

Open radio-access network, or Open RAN, is a type of network architecture in which baseband and radio unit components from different suppliers can operate seamlessly in concert. Advances in network communication were, until recently, hampered by the proprietary network operations of each mobile operator; the advent of 5G, however, with its service-based architecture model, has finally opened the door to the expansion of connectivity on the Open RAN model. This transformation promises to define the future of mobile network architecture.

Open RAN Explained is among the first books dedicated to this groundbreaking technology. Its comprehensive but accessible summary of current and future developments in Open RAN promises to facilitate network deployment and device design, as well as to provide a handy reference for network professionals in a range of different fields. The result is a must-read volume for anyone looking to understand the future of wireless communication.

Open RAN Explained readers will also find:

• In-depth description of the challenges and opportunities of network modularization
• Analysis conversant with the latest release specifications of the O-RAN Allliance, GSMA OP/TIP, and other key emerging technologies
• Authors working at the leading edge of 5G network communications

Open RAN Explained is ideal for network operators, network element and device manufacturers, telecommunications researchers, and advanced students, as well as industry-adjacent figures such as regulators, consultants, and marketing professionals.
