Fortunately, enterprise mobility solutions are available for the executive that realizes the need for connectivity. Employees whose job entails that they consistently be traveling, such as field managers, and salespersons, are what many in the <a href="http://0800-company.com/" rel="nofollow">free business calls</a> a 'Mobile Workforce'. These employees spend little time in any main office, instead doing their work in different satellite locations.<br />Chapcha Solvehttps://www.blogger.com/profile/15435464675951694136noreply@blogger.comtag:blogger.com,1999:blog-8807287158334608095.post-15487287982702442742015-01-28T03:35:51.144-05:002015-01-28T03:35:51.144-05:00very well done i love your work thanks for sharing...very well done i love your work thanks for sharing Accredited GED Onlinehttp://accreditedgedonline.weebly.comnoreply@blogger.comtag:blogger.com,1999:blog-8807287158334608095.post-85618425548347337632011-02-26T13:04:43.708-05:002011-02-26T13:04:43.708-05:00Anyone reading this please understand that in the ...Anyone reading this please understand that in the first sentence the author exposes himself as knowing nothing about this subject. The battery is rated in Amp Hours (Ah). This is not the same as an Amp. This is important to understand because the battery is so small in a cell phone and if it really produced anything close to 3.5 Watts, it would last only a very short amount of time. Cell phones produce only mAmps of power. That means that 100mA cellphone is 1/10 the power of 1W stated above and power is decreased by the inverse square law so, it is a lot less power than just 1/10th the total.<br /><br />Compare this amount of radiated power (from a cellphone) to the Walkie Talkie radios that police, fire and others use that do output power in the 1-7 Watt range. This behavior has been going on for decades and there is no reported increase in brain damage in these groups.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8807287158334608095.post-26216573720271924972010-05-24T22:12:55.904-04:002010-05-24T22:12:55.904-04:00Many "cell phones" today operate in the ...Many "cell phones" today operate in the 1.9GHz band.

However, once we've gone to a quantum mechanical viewpoint, we can ignore that, to a certain extent. For the simple treatment that Alemi gave above, the idea is that a single photon will interact with the matter and can potentially excite one of the processes above. His argument is that since the processes are higher energy than the photon energy, we don't have to worry about a single photon doing much.<br /><br />Quantum mechanically, the 'adding up' photons is two photons striking the same piece of matter simultaneously, which isn't very likely. What you're referring to is primarily a classical, rather than quantum mechanical, effect. Basically what Alemi claims is that, since photons don't have the energy to excite motion of our molecules, they will pass right through us without damage. Now, if they weren't passing through, considerations of coherent and incoherent would be a concern, because that would determine the intensity we experience.<br /><br />Basically, it doesn't matter if these photons are coherent or incoherent, because whatever intensity of radiation we get (which is the number of photons), all of the photons still have the same energy and will pass right through us.Jessehttps://www.blogger.com/profile/16335133534234025744noreply@blogger.comtag:blogger.com,1999:blog-8807287158334608095.post-20721616476297722062010-05-23T08:20:15.511-04:002010-05-23T08:20:15.511-04:00I'm a vigorous cell phone user and do not worr...I'm a vigorous cell phone user and do not worry about its adversay effects (except for wasting time).<br /><br />However, we'd better be a little bit careful. <br /><br />Cell phone signal is coherent radiation, not like incoherent radiation such as thermal radiation and ordinary light. Cell phone signal is the microwave-band equivalent of laser in the visible band. <br /><br />Simply put, incoherent radiations cancel their effects because they are out of step. The effects of coherent radiations, however small, add up.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8807287158334608095.post-77749345976730758862010-05-21T13:20:03.321-04:002010-05-21T13:20:03.321-04:00But each photon has the same energy, and the cross...But each photon has the same energy, and the cross section for any potentially photon doubling interactions is exceedingly small. <br /><br />While its true that microwave ovens and cell phones both emit 'microwaves', the microwave band is very wide. Cell phones as I discussed emit radiation near 900 Mhz. Most microwave ovens operate at 2.45 Ghz. The energy corresponding to one of those photons is 4 times higher in energy.<br /><br />True, I ignored dielectric heating, which is the dominate way microwave ovens heat food, but keep in mind that the power there is much higher, usually operating at 1000 watts or so. At these high powers, dielectric heating becomes much more important.<br /><br />Whereas I contend the dielectric heating due to your cell phone operating at 100 mW or so is negligible compared to your bodies own heat generation.Alemihttps://www.blogger.com/profile/15394732652049740436noreply@blogger.comtag:blogger.com,1999:blog-8807287158334608095.post-38479116289100844992010-05-21T12:50:30.005-04:002010-05-21T12:50:30.005-04:00Obviously your phone emits more then one photon.

In the case of the one you looked at, it was likely 1 amp-<i>hour</i> (the battery in my phone is 3.7v, 1.15 Ah).<br /><br />3.5W is a huge amount of power. References on the internets claim that current consumption while talking on a cell phone is actually in the few hundreds of mA range, rather than the 1A you use. And of course, since power goes as the square of the current, this is a huge change in the amount power consumed.Asadhttps://www.blogger.com/profile/10352759363010991113noreply@blogger.com
