Next Generation Mobile Communications Ecosystem: Technology Management for Mobile Communications

1

Introduction

Mobile Communications is one of the most valuable innovations of the twentieth century. It started in the 1970s and became one of the most common forms of communications in the mid 2000s. Mobile wireless communications is continuously evolving and mobile phone is all set to become the Third Screens after TV and computer.

It is a single technology that enables voice communications like traditional landline, broadband data communications like DSL (Digital Subscriber Line), financial services like banks and infotainment like TV. The journey started with first generation analog systems and moved to second generation digital telephony with GSM (Global System for Mobile Communications), USDC (US Digital Cellular), CDMAOne (Code Division Multiple Access) and PDC (Pacific Digital Cellular) systems. The journey continued with the migration to third generation (3G) systems in the early 2000s. The three 3G standards are CDMA2000, TD-SCDMA (Time Division – Synchronous CDMA) and UMTS (Universal Mobile Telecommunications Systems) [1].

Contrary to what is stated by many industry players both EPS (Evolved Packet System) and WiMAX (Worldwide Interoperability for Microwave Access) are part of ITU (International Telecommunications Union) IMT-2000 (International Mobile Telecommunications) framework and are not 4G technologies. IMT-2000 is a framework from the ITU for 3G wireless phone standards throughout the world that deliver high-speed multimedia data as well as voice. EPS is an ...
