THIS SIEMENS S46 PHONE MEETS THE GOVERNMENT’S RE- QUIREMENTS FOR EXPOSURE TO RADIO WAVES.

Your wireless Siemens S46 phone is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the U.S. Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health.

The exposure standard for wireless mobile phones employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg.* Tests for SAR are conducted using standard operating positions specified by the FCC with the phone transmitting at its highest certified power level in all tested frequency bands. Although the

SAR is determined at the highest certified power level, the actual SAR level of the phone while operating can be well below the

maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output.

Before a phone model is available for sale to the public, it must be tested and certified by the FCC that it does not exceed the limit established by the government- adopted requirement for safe exposure. The tests are performed in positions and locations (for example, at the ear and worn on the body) as required by the FCC for each model. The highest SAR value for this Siemens S46 phone when tested for use at the ear is

1.12W/kg, and when worn on the body, as described in this user guide, is 0.41 W/kg. (Body-worn measurements differ among phone models, depending upon available accessories and FCC requirements.) While there may be differences between the SAR levels of various phones and at various positions, they all meet the government requirement for safe exposure.

GSM 900, GSM 1900, TDMA 1900, TDMA 800 specifications

Siemens is a renowned telecommunications equipment manufacturer known for its innovative solutions in mobile communication. Among its notable contributions are the TDMA 800, TDMA 1900, GSM 900, and GSM 1900 systems. These technologies have played a significant role in shaping mobile telephony, particularly during the late 20th century.

TDMA, or Time Division Multiple Access, is a digital transmission protocol that allows multiple users to share the same frequency channel by dividing the signal into time slots. The Siemens TDMA 800 operates in the 800 MHz frequency band, which is ideal for regional mobile communication. Its main features include improved call quality, greater capacity, and effective handover capabilities. This system was particularly popular in the United States, where it formed the backbone of early digital cellular networks.

On the other hand, the TDMA 1900 operates in the 1900 MHz band, catering to urban areas with higher population densities. This system further enhances voice clarity and offers faster data transmission speeds. Its key characteristics include support for features such as call waiting, caller ID, and enhanced voice privacy, making it suitable for modern telecommunication needs.

GSM, or Global System for Mobile Communications, is another critical technology developed by Siemens. The GSM 900 operates at 900 MHz and is one of the most widely adopted mobile standards globally. Its contributions to the communication landscape include superior frequency reuse, allowing for a greater number of simultaneous calls. The GSM 900 also supports various services beyond voice calls, including SMS (Short Message Service) and basic data transmission.

Meanwhile, GSM 1900, which functions in the 1900 MHz frequency band, is predominantly used in North America. This technology shares many features with GSM 900, but it accommodates a larger number of channels per frequency unit due to its higher frequency. The GSM 1900 system has been critical in facilitating the growth of mobile data services, providing a solid foundation for the evolution of mobile internet access.

Overall, Siemens' TDMA and GSM technologies have significantly influenced the development of mobile telecommunications. With features focused on capacity, flexibility, and quality, these systems established the groundwork for the advanced mobile networks we rely on today. Their legacy continues to be seen in the current generation of wireless technologies, highlighting the importance of innovation in the telecommunications industry.
