4. What makes technology greener ?
• Products use less toxic materials
• Disposable items are easily recyclable
• Upward compatibilities of hardwares to minimize waste
• None or minimum effects on humans and the echo system

SAR MEASUREMENT TECHNIQUE

46. RESULTS
Cell Phone Radiation is Absorbed More
Deeply Into the Brains of Children

47. 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.

49. Personal radiation monitor and alert
unit for cellular phones

50. Coming back to greener WIMAX
• Lesser BTS
• Could be placed at remote locations
• Lesser SAR Effects
• ECO FRIENDLY

51. Conclusion
• However, conclusions about possible adverse
effects on human health are premature as the
underlying mechanisms of these non-thermal
effects are unknown.
