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 1 Carrier (CDMA2000 1x) technology, advocated by the 3rd Generation

Partnership Project 2 (3GPP2), has been widely used for commercial purpose. The CDMA2000 1x technology is compatible with IS -95A and IS-95B standards. The

capacity of the CDMA2000 1x system increas es substantially thanks to technologies such as reverse pilot, fast power control and transmits diversity.

As the evolution of the CDMA2000 1x, 1xEV-DO (EVolution-Data Optimized) can provides a peak forward data rate at 2.4 Mbps and a peak reverse data rate at 153.6 kbps. It can deliver diversified radio data services such as multi-media gaming, multi-media news, real-time video traffic news, video phone, video conference, real-time security information, and location-base services.

Technical Manual Airbridge BTS3606A CDMA Base Station

Note:

The appearance of the BTS3601C cabinet is the same as the ODU3601C cabinet.

1.2.1 Brief Introduction to BSS/AN

The BSS is a concept used in the CDMA2000 1x network. It consists of the Base Transceiver Station (BTS), Base Station Controller (BSC), and Packet Control Function (PCF). The PCF is usually integrated with the BSC. The ODU3601C, a soft BTS, is also a part of the Huawei BSS.

The AN is a concept used in the 1xEV-DO network. It consists of the 1xEV-DO BTS and BSC (integrated with PCF).

I. BTS

The BTS transmits and receives radio signals to enable the communication between the radio network system and the Mobile Station/Access Terminal (MS/AT). Huawei provides a series of BTS products, including:

System Description

Chapter 1 Introduction

l BTS3606A: Outdoor BTS equipment supporting the CDMA2000 1x and

CDMA2000 1xEV-DO standa rds. The maximum capacity of a single cabinet is six sector carriers. With the multi-carrier technology, the BTS3606A can support a maximum of 18 sector carriers.

l BTS3606: Indoor BTS equipment supporting the CDMA2000 1x and CDMA2000

1xEV-DO standards. The maximum capacity of a single cabinet is six sector carriers. With the multi-carrier technology, the BTS3606 can support a maximum of 18 sector carriers.

l cBTS3612: Indoor BTS equipment supporting both the CDMA2000 1x and

1xEV-DO standards. The maximum capacity of a single cabinet is 12 sector carriers.

l BTS3612A: Outdoor BTS equipment supporting both the CDMA2000 1x and

1xEV-DO standards. The maximum capacity of a single cabinet is six sector carriers.

l BTS3601C: Outdoor one-carrier BTS equipment supporting the CDMA2000 1x

standard.

l ODU3601C: Outdoor one-carrier soft BTS equipment supporting the CDMA2000

1x standard. It shares the baseband processing resource of its upper-level BTS . It also transmits and receives the radio signals together with the upper-level BTS.

II. BSC/PCF

The BSC performs the following functions:

l BTS control and management l Call connection and disconnection

1-3

Technical Manual Airbridge BTS3606A CDMA Base Station

l Mobility management l Power control l Radio resource management l Provision of stable and reliable radio connections for the upper-level services

through soft/hard handoff

The PCF manages the Radio-Packet (R-P) connection. As radio resources are limited, they should be released when subscribers are not sending or receiving any information. But the Peer -Peer Protocol (PPP) connection must be maintained. The PCF shields the

radio mobility from the upper-level services through the handoff function.

III. MS/AT

l MS

MS is the equipment used by the mobile subscriber. It can originate and receive calls, and communicate with the BSS.

l AT

AT is a device with a radio modem and a data interface that allows the user to access a packet data network through the 1xEV-DO Access Network.

System Description

Chapter 1 Introduction

An AT is analogous to a mobile station in an CDMA2000 1x system. It may be connected to a computing device like a laptop computer or may be a self-contained data device like a Personal Digital Assistant (PDA).

1.2.2 Brief Introduction to CN

The CN comprises the packet domain network and the circuit domain network.

I. Packet domain network equipment

The packet domain network equipment covers

l Packet Data Service Node (PDSN) l Mobile Internet Protocol Home Agent (MIP HA) l Authorization, Authentication and Accounting (AAA)

They connect to and communicate with the Internet.

II. Circuit domain network equipment

The circuit domain network equipment includes

l Mobile Switching Center (MSC) l Home Location Register (HLR) l Gateway Mobile-services Switching Center (GMSC).

They connect to and communicate with the conventional Public Land Mobile Network (PLMN) and Public Switched Telephone Network/Integrated Services Digital Network

(PSTN/ISDN).

The main/diversity receiving technology is employed to optimize the receiving performance. In the case of RC3, the receiver sensitivity of the BTS3606A is better than -127 dBm in the single -carrier mode and better than –126 dBm in the multi-carrier mode.

Chapter 2 Product Features

System Description

II. Transmit power (measured at the antenna port of the cabinet)

l Single-carrier mode

The maximum average transmit power is 25 W. When the large-power combiner is configured, two powers can be combined to

output an average transmit power up to 50 W.

l Multi-carrier mode

When the BTS3606 operates at 450 MHz, it does not support the multi-carrier. When the BTS3606 operates at 800 MHz, the maximum average transmit power

is 50 W. When the BTS3606 operates at 1900 MHz, the maximum average transmit power
