Wi-Fi, WiMAX, Why Care?
Mobile WiMAX won’t kill Wi-Fi
Competitive, But Not a Replacement
Wi-Fi & WiMAX are Friends

SAR MEASUREMENT TECHNIQUE
RESULTS
Cell Phone Radiation is Absorbed More Deeply Into the Brains of Children
Results Analysis and Discussion
• IT IS FOUND THAT THE PEAK SAR OF THE HEAD CAN BE REDUCED BY PLACING THE META MATERIALS BETWEEN THE ANTENNA AND THE HUMAN HEAD.
• Determined using the Finite Difference Time Domain (FDTD) method.
Personal radiation monitor and alert unit for cellular phones
Coming back to greener WIMAX
• Lesser BTS • Could be placed at remote locations• Lesser SAR Effects • ECO FRIENDLY
Conclusion
• However, conclusions about possible adverse effects on human health are premature as the underlying mechanisms of these non-thermal effects are unknown.
