  • SAR: Specific Absorption Rate. A measure of the rate at which radio frequency (RF) energy is absorbed by the body when using a cellular telephone. The United States and Europe have set different limits for safe exposure. In the U.S. SAR level must be equal to or below 1.6 watts per kilogram (W/Kg) taken over a volume of 1 gram of tissue. In Europe SAR level must be equal to or below 2.0 watts per kilogram (W/Kg) taken over a volume of 10 gram of tissue. SAR values presented in above list are taken from the Swedish site Mobil Net.

  • Network support: The four GSM frequency bands include the 850 and 1900 MHz bands - used in the Americas - and 900 / 1800, used in most other parts of the world. Compared to a tri-band phone supporting the 900 / 1800 / 1900 bands, a quad-band phone adds support for GSM 850 for full coverage in the Americas.
