If you are a technical person that works for a company that competes with the cellular providers, this course will help you understand the competition. If your company provides cellular services, you will benefit from understanding those technologies. This course takes the student through the evolution of cellular mobile networks. It covers GSM, GPRS, UMTS, HSPA+, LTE and the latest network evolution LTE Advance. It provides students with an understanding of how the radio air interface has evolved from enabling voice calls, to supporting mobile packet data in excess of gigabits per second. This course also shows the evolution of the core network from a circuit switched network to an all IP based network.
