CHAPTER 1 OVERVIEW OF MOBILE COMMUNICATION (p. 1)

YONGWAN PARK AND FUMIYUKI ADACHI
Abstract:
Following chapter introduces the mobile communication, gives a short history of wireless communication evolution, and highlights some application scenarios predestined for the use of mobile devices. Cellular and wireless based systems related to different generations of mobile communication, including GSM, IS-95, PHS, AMPS, D-AMPS, cdma2000 and WCDMA are also described by this Chapter.

Much attention in this chapter is given to express the wireless based networks, such as Wi-Fi and WiBro/WiMax, and wireless broadcasting systems, including DMB, DVB-H, and ISDB-T. We conclude the chapter with the future vision of mobile communication evolution

1. INTRODUCTION TO MOBILE COMMUNICATION SYSTEM

To this day, there have been three different generations of mobile communication networks. First-generation of (1G) wireless telephone technologies are the analog cell phone standards that were introduced in the 80s and continued until being replaced by 2G digital cell phones in 1990s.

Example of such standards are NMT (Nordic Mobile Telephone), used in Nordic countries, NTT system in Japan, and the AMPS (Advanced Mobile Phone System) operated in the United States. The secondgeneration (2G) technology is based on digital cellular technology. Examples of the 2G are the Global System for Mobile Communications (GSM), Personal Digital Cellular (PDC), and North American version of CDMA standard (IS-95).

The third generation (3G) started in October 2001 when WCDMA network was launched in Japan. The services associated with 3G provide the ability to transfer both voice data (a telephone call) and non-voice data (such as downloading information, exchanging email, and instant messaging).

Figure 1 illustrates a brief overview on each generation. More detail information about mobile communication evolution steps is given in section 2. The advances in cellular systems, wireless LANs, wireless MANs, personal area networks (PANs), and sensor networks are bound to play a significant role in the people communication manner in the future. It is expected that in the following years most of the access part of the Internet will be wireless.

Increasing capacity and data rate of mobile communication systems enable to develop extended applications and services. Figure 2 demonstrates some application environments and modern services focusing on South Korea and Japan’s markets and technology trends. The current and awaited mobile services in these countries can be viewed as follows:

E-mail: This is a killer application regardless of the mobile network generation. The e-mail applications both send a message to other mobile phone or to anyone who has an Internet e-mail address. Mobile terminals also can receive e-mail.
