Page 4: General Introduction
General Introduction General Introduction The KF600w phone has been designed to operate on the latest digital mobile communication technology, Code Division Multiple Access (CDMA). This CDMA digital technology has greatly enhanced voice clarity and can provide a variety of advanced features. Currently, CDMA mobile communication technology has been commercially used in Cellular and Personal Communication Service (PCS).
Page 5: Chapter 1. System Introduction
Chapter1. System Introduction Chapter1. System Introduction 1. CDMA Abstract The CDMA mobile communication system has a channel hand-off function that is used for collecting the information on the locations and movements of mobile telephones from the cell site by automatically controlling several cell site through the setup of data transmission routes, and then enabling one switching system to carry out the automatic remote adjustment.

2. Features and Advantages of CDMA Mobile Phone 2.1 Various Types of Diversities When employing the narrow band modulation (30kHz band) that is the same as the analog FM modulation system used in the existing Cellular system, the multi-paths of radio waves create a serious fading. However, in the CDMA broadband modulation (1.25MHz band), three types of diversities (time, frequency, and space) are used to reduce serious fading problems generated from radio channels in order to obtain high-quality calls.
Page 7 2.3 Voice Encoder and Variable Data Speed The bi-directional voice service having variable data speed provides voice communication which employs voice encoder algorithm having power variable data rate between the base station and the mobile station. On the other hand, the transmit voice encoder performs voice sampling and then, creates encoded voice packets to be sent out to the receive voice encoder, whereas the receive voice encoder demodulates the received voice packets into voice samples.
Page 8 Total interference from all the adjacent cell sites is the ratio of interference from all the cell sites versus total interference from other mobile stations in the same cell site (about 65%). In the case of directional cell site, one cell normally uses a 120°sector antenna in order to divide the sector into three.

3. Structure and Functions of tri-band CDMA Mobile Phone The hardware structure of CDMA mobile phone is made up of radio frequency (RF) part and logic part. The RF part is composed of Receiver part (Rx), Transmitter part (Tx) and Local part (LO). For the purpose of operating on tri- band, It is necessary dual Tx path, tri Rx path, dual PLL and switching system for band selection.

CHAPTER 5. Safety CHAPTER 5. Safety ▣ IMPORTANT Read This Information Before Using Your Hand-Held Portable Cellular Telephone First introduction in 1984, the hand-held portable Cellular telephone is one of the most exciting and innovative electronic products ever developed. With it you can stay in contact with your office, your home, emergency service, and others. For the safe and efficient operation of your phone, observe these guidelines.
Page 124 ▣ Driving Check the laws and regulations on the use of Cellular telephones in the areas where you drive. Always obey them. Also, when using your phone while driving, please: Give full attention to the driving. Use hands-free operation, if available, and pull off the road and park before making or answering a call if driving conditions require.
Page 125 Do not transport or store flammable gas, liquid, or explosives in the compartment of your vehicle which contains your phone or accessories. Vehicles using liquefied petroleum gas (such as propane or butane) must compl7y with the National Fire Protection Standard (NFPA-58). For a copy of this standard, contact the National Fire Protection Association, One Battery march Park, Quincy, MA 02269, Attn: Publication Sales Division.
Page 126: Chapter 6. Glossary
CHAPTER 6. Glossary CHAPTER 6. Glossary General Terms Abbreviated Alert. An abbreviated alert is used to remind the mobile station user that previously selected alternative routing features are still active. AC. See Authentication Center. Access Attempt. A sequence of one or more access probe sequences on the Access Channel containing the same message.
Page 127 Analog Access Channel. An analog control channel used by a mobile station to access a system to obtain service. Analog Color-Code. An analog signal (see Supervisory Audio Tone) transmitted by a base station on an analog voice channel and used to detect capture of a mobile station by an interfering base station or the capture of a base station by an interfering mobile station.
Page 128 CDMA Channel Number. An 11-bit number corresponding to the center of the CDMA frequency assignment. CDMA Frequency Assignment. A 1.23MHz segment of spectrum centered on one of the 30KHz channels of the existing analog system. Code Channel. A subchannel of a Forward CDMA Channels. A Forward CDMA Channel contains 64 code channels. Code channel zero is assigned to the Pilot Channel.
Page 129 Discontinuous Transmission (DTX). A mode of operation in which a mobile station transmitter autonomously switches between two transmitter power levels while the mobile station is in the conversation state on an analog voice channel. Distance-Based Registration. An autonomous registration method in which the mobile station registers whenever it enters a cell whose distance from the cell in which the mobile station last registered exceeds a given threshold.
Page 130 Forward Traffic Channel. A code channel used to transport user and signaling traffic from the base station to the mobile station. A basic timing interval in the system. For the Access Channel, Paging Channel, and Traffic Channel, a frame is 20 ms long.
Page 131 Local Control. An optional mobile station feature used to perform manufacturer-specific functions. A PN sequence with period 242-1 that is used for scrambling on the Forward CDMA Channel and spreading on the Reverse CDMA Channel. The long code uniquely identifies a mobile station on both the Reverse Traffic Channel and the Forward Traffic Channel.
Page 132 Modulation Symbol. The output of the data modulator before spreading. On the Reverse Traffic Channel, 64-ary orthogonal modulation is used and six code symbol (when the data rate is 9600bps) or each repeated code symbol (when the data rate is less than 9600bps) is one modulation symbol. Ms.
Page 133 Ordered Registration. A registration method in which the base station orders the mobile station to send registration related parameters. Overhead Message. A message sent by the base station on the Paging Channel to communicate base-station-specific and system-wide information to mobile station. Overload Class.
Page 134 PN Chip. One bit in the PN sequence. PN Sequence. Pseudonoise sequence. A periodic binary sequence. Power Control Bit. A bit sent in every 1.25ms interval on the Forward Traffic Channel to signal the mobile station to increase or decrease its transmit power. Power Control Group.
Page 135 Response. A layer 3 message generated as a result of another message, typically a request. Reverse Analog Control (RECC). The analog control channel used from a mobile station to a base station. Reverse Analog Voice Channel (RVC). The analog voice channel used from a mobile station to a base station. Reverse CDMA Channel.
Page 136 Soft Handoff. A handoff occurring while the mobile station is in the Mobile Station Control on the Traffic Channel State. This handoff is characterized by commencing communications with a new base station on the same CDMA frequency assignment before terminating communications with the old base station. See also Hard Handoff. SOM.
Page 137 TOLR. See Transmit Objective Loudness Rating. Traffic Channel. A communication path between a mobile station and base station used for user and signaling traffic. The term Traffic Channel implies a Forward Traffic Channel and Reverse Traffic Channel pair. See also Forward Traffic Channel and Reverse Traffic Channel.
