  • Page 3: General Introduction

    KG70c General Introduction The KG70c cellular phone functions as digital cellular phone worked in CDMA (Code Division Multiple Access) mode. CDMA mode applies the DSSS (Direct Sequence Spread Spectrum) technique that has been used in military. This technique enables to share one frequency channel with many users in the same specific area.

    KG70C 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.
  • Page 6 KG70C Moreover, the backward closed loop power control used by the mobile station to control power with the commands issued out by the cell site. The cell site receives the signal of each corresponding mobile station and compares this with the pre-set threshold value and then, issues out power increase/decrease commands to the corresponding mobile station every 1.25 msec (800 times per...
  • Page 7 KG70C 2.6 Frequency Re-Use and Sector Segmentation Unlike the existing analog cellular system, the CDMA system can reuse the same frequency at the adjacent cell and accordingly, there is no need to prepare a separate frequency plan. Total interference generated on mobile station signals received from the cell site is the sum of interference generated from other mobile stations in the same cell site and interference generated from the mobile station of adjacent cell site.

    KG70C CHAPTER 4. 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 54 KG70C ▣ Antenna Care and Replacement Do not use the phone with a damaged antenna. If a damaged antenna comes into contact with skin, a minor bum may result. Replace a damaged antenna immediately. Consult your manual to see if you may change your antenna yourself.
  • Page 55 KG70C ▣ Children Do not allow children to play with your phone. It is not a toy. Children could hurt themselves or others (by poking themselves or others in the eye with the antenna, for example). Children also could damage the phone, or make calls that increase your telephone bills.
