Radiation value is only a few tenths of a cell phone, almost negligible, belonging to the radiation-free products, can be used with confidence,
Belongs to the green use of cell phones in Europe and the United States has been quite popular
The convenience of mobile communications prompted by the high speed of development, so that the amount of cell phone ownership has risen sharply, more than ten years of work, China from analog to digital mobile phone development, from 800 megabytes, 900 megabytes of development to CDMA, 3G technology. Cell phone development to digital cell phones, from 800 megabytes, 900 megabytes of development to CDMA, 3G technology, China, a conservative estimate of cell phone ownership in the 300 million or so, has become a real use of cell phones in the country, as old as 60, 70 years old, down to the eight or nine-year-old child, have become the owner of a cell phone, cell phones, has become an indispensable tool for communication in people's daily lives.
With the popularity of cell phones, a question about "cell phone radiation" has been included in the research topics of communication experts and health experts. From 1999, some scientists about "cell phone radiation" reports began to appear in the press, caused a wide range of controversy,
Mobile phones are radioactive, in the plane, at the gas station, in the operating room prohibited the use of cell phones, indicating the objective existence of cell phone radiation hazards, able to interfere with the machine, not interfere with the human body? What's the point? Is flesh still stronger than steel! Does it not affect the human body when every incoming call from a cellular phone makes the picture of a television set shake and produces a piercing murmur from a wired telephone? In fact, some sensitive cell phone users experience "ringing in the ears", "warmth in the ears", "migraines", "hearing loss", etc. after each long call. Hearing loss" and other phenomena, some of the elderly, pregnant women are trying to avoid the use of cell phones
China's National Standards Committee as early as 2001, the "electromagnetic radiation pollution" as water pollution, air pollution, noise pollution after the fourth major pollution, see the country a moment have not stopped on the cell phone "radiation pollution". Stopped on the cell phone "radiation pollution" concern.
The definition and prevention of cell phone radiation, from the cell phone and the network to solve the two systems, there are still many technical and economic double problems.
The emergence of Bluetooth technology for the "cell phone radiation" of the complete solution to the end.
Bluetooth is the name of a Danish king in the Middle Ages, who was known for his love of novelty, which coincided with the new look of Bluetooth products. Bluetooth technology originated in 1994 and is a new wireless technology protocol jointly promoted by Ericsson, IBM, Intel, Nokia and Toshiba. As a short-range, low-power wireless data transmission standard, Bluetooth technology operates in the 2.4GHz frequency band, with a hopping bandwidth of 79MHz, a maximum data transmission speed of 1Mbps, and a maximum transmission distance of 10 meters, which allows simultaneous interconnection and communication of multiple devices.
A panel of experts from the World Health Organization and the IEEE said the test did not find that the radiation from Bluetooth products has an impact on the human body. Bluetooth products, the output power of only 1 milliwatt, is one millionth of the power used in microwave ovens, is one thousandth of the power of mobile phones
Bluetooth headset for cell phones is not a direct "elimination" of "cell phone radiation", but with isolation measures, through the Bluetooth headset, the mobile phone radiation is not a direct "elimination", but with isolation measures. Measures, through the Bluetooth headset to the human body may have "radiation pollution" of the cell phone and the human body separately, so that the cell phone in the handbag or desk away from the human body, so as to avoid the cell phone on the human body may constitute a variety of hazards. The use of Bluetooth headset, not only cut off the black hand may pollute the human body, but also due to its wireless characteristics and better sound quality, freeing up the hands, making wireless communication more increased endless fun, the phone can not need hands to play. Drivers, surgeons, actors, conductors, and even traffic police can be free from the shackles of cell phone opponents. Mobile new era is about to come again due to the emergence of bluetooth headset, become a kind of healthy communication lifestyle
