SUMMARY

The discussion focuses on the relationship between Specific Absorption Rate (SAR) values and mobile phone frequencies, specifically comparing 950 MHz and 1800 MHz. It concludes that the frequency that generates higher SAR values can be determined using the SAR formula provided on the Wikipedia page. Users are directed to utilize the RMS values in the frequency domain to accurately calculate SAR for different frequencies.

PREREQUISITES
  • Understanding of Specific Absorption Rate (SAR)
  • Familiarity with mobile phone frequency bands
  • Knowledge of RMS (Root Mean Square) calculations
  • Basic grasp of electromagnetic radiation principles
NEXT STEPS
  • Research the SAR formula and its application in mobile technology
  • Learn how to calculate RMS values for different frequencies
  • Explore the health implications of SAR values in mobile devices
  • Investigate regulations regarding SAR limits for mobile phones
USEFUL FOR

Researchers, health professionals, and mobile technology developers interested in understanding the impact of mobile phone frequencies on human tissue absorption rates.

hello first,

i want to know the relation between the SAR values absorbed by the living tissue and the frequency of mobile phones? in other word which frequency create the higher SAR 950 MHz or 1800 MHz and why??

I think you can go here: http://en.wikipedia.org/wiki/Specific_absorption_rate
use the formula on the page. You'll have to click on the RMS link right under that formula and then go down to RMS in frequency domain in order to get the right numbers for frequency to put into the SRA formula.
