Chapter 1 Introduction

The mobile communication system has experienced the first generation (analog system) and the second generation (digital system). As one of the main development trends of the second generation, the Code Division Multiple Access 1X (CDMA 1X) technology, advocated by the 3rd Generation Partnership Project 2 (3GPP2), has been widely used for commercial purpose.

The CDMA 1X technology complies with IS-95A and IS-95B standards. The capacity of the CDMA 1X system has increased substantially because it adopts such technologies as reverse pilot, fast power control and transmit diversity.

This chapter first introduces the network solution of Huawei CDMA 1X mobile communication system, and then the market position of Huawei indoor BTS3606.

1.1 Network Solution of Huawei CDMA 1X System

The Huawei CDMA 1X mobile communication system comprises the Base Station Subsystem (BSS) and the Core Network (CN). Users can operate and maintain the system through an integrated mobile network management system.

Figure 1-1 shows the network of Huawei CDMA 1X system. This manual aims to introduce the Base Transceiver Station (BTS) of the BSS, thus, the following figure emphasizes the network structure of BSS.
