. Z/ a! B* Q9 K* h8 F has been heard, CDMA mobile phone radiation of small, GSM mobile phone radiation compared to larger,tn requin, it would only have heard, there is no opportunity to test. Are talking about here refers to Telecom's CDMA network CDMA1X, voice calls used by the network.
very early to do the actual testing, picture date is good in a few months ago. Never too busy to come write this short test report. Today, organize files, we find these materials, so they have used the break to write about.
instruments: a radiation tester,juicy tracksuits, model QX-3, Test Bandwidth 5Hz-5000MHz, resolution 1μW/cm2, single-axis sensor axis, accuracy ± 10%, response time of 0.5 seconds,abercrombie hoodies, electrical insulation 3000V AC , 10 minutes without leakage current, R & D units in China Institute of Radiation Protection;
  A% s; _- t& b& c Mobile: C network: Dopod S500; Huawei 2906,hollister shirts; Samsung S189; G network: Nokia 3100.
( P" s" G3 H: Q/ G# N I am not selling mobile phones, so the machine is not capable of testing more are in the hands can be immediately collected, a high-end machine (at present should not a), the rest are low-end machines. Not to mention the poor quality of low-end machines, radiation on, and of course there must be some truth in this, but anyhow my test machine is a brand machine, non-cottage planes also. Because of radiation depends on the mobile phone design, and network is closely related to what the network will determine the basic parameters of radiation.
; K3 h3 B% f- e+ c- y# x% M7 N' l1 q6 Q the testing process as follows: Dial the phone to call the state at the moment to use the cell phone radiation tester around the radiation, known to the acceptance of radiation tester located in the top of the instrument, so close to the top of the test instrument appearance of a total of six position cell phone will be derived from values in mind, I use the camera capture mode records of value. Because the phone's antenna design in mobile phones are also at the top, so the test in accordance with the following picture can be placed in the basic way the real value.
, N: {7 T2 t8 i4 t! P% v# j nonsense small, start on the map.
Huawei 2906,ralph lauren big pony, call number 10000 telecommunications, use the tester 6 position, apparatus, value is always 0
7 b. ~7 X. I& _; R( E4 i9 l Samsung S189, is also a low-end machines, dial 10000 test results, radiation tester shows 0 is always
; \' k) p1 p/ I1 x0 c9 G3 J to high-end machines, Dopod S500, dial 10000 numbers, radiological readings for the tester is always 0
# a5 g2 H$ \* {1 o+ s5 D; m5 V replaced by G network machines, Nokia 3100, I have a machine used during the University, has retired, call mobile number 10086,christian louboutin heels, the highest parts of tester near the antenna, taking the average of about 400
; |" \6 c& A* y! p. O2 Y+ F! g do no more G-network machines tested. Usually to the customer to test their own time machine G network, to get the value, and some G network machines can actually measure in 2000, but there is one exception, a customer's Nokia 5800 has not even measured values, the guess that Taiwan in the design of the machine may be relatively well to do more radiation shield in place, give full consideration to human safety.
Conclusion: After this simple test, we can fully explain the network based on Qualcomm's CDMA mobile phone because of the design advantages, ordinary C network mobile phone radiation is far less than the normal G mobile phone network. This also shows that there is no figure above test out the results (ie the picture test results show that as 0) is not to say that there is no cell phone radiation, but radiation is very small, less than the sensitivity tester, testers did not test out the results of only. Since the communication must, must produce radio waves, there is no radiation that is not possible, but the size of the level of radiation only.
" A) i5 E- r8 ?' b) F! k7 F. q# o a result of this test, and finally arrived at the C Machine used to say green, there is indeed a certain basis.
