Actually, it does matter.
You will find that often times the belt clip gives a higher power density measurement than direct contact, This is normally down to two factors.
The wavelength of the band and the fact that most clips have a metal spring. This spring can have a coupling affect and change the radiation pattern of the phone.
Actually, it does matter.
Actually, there should not be any phones transmitting at 3 watts.
The highest in the US is GSM in the 850 MHz band. That is 2 watts, or 33 dBm.
Of course, nowadays most phones are using either UMTS or LTE.
So, in the same band, or any band for that matter will have a maximum output power of 24 dBm or 251 mW. Of course, by law you can transmit up to 7 Watts in some bands, but the networks do not allow for these high power class devices, so 24 dBm is the highest you will see as a consumer.
You cannot "boost the radio" to get better reception. Reception is a function of the receiver and not one of output power. This is dictated by the gain of the antenna and receiver sensitivity. Depending on the band in use, that would be around -103 dBm TIS (Total Isotropic sensitivity).
Of course, this is an average in free space measured in a sphere. There will certainly be angles at which the performance is poor relative to the peak sensitivity.
Seriously, this is utter nonsense.
Is SAR testing performed in body worn configuration using the belt clip? Sure it is. It is also done and various angles.
It is also tested against the head. It is also tested with a 1-5 mm separation distance. It is also tested with direct contact, and against the head, and extremities.
SAR is tested in a lot of configurations. Belt clips are just one of them.
Also, the author of the article clearly does not understand waveforms.
Putting a phone in your pocket does NOT mean that your exposure is higher than when using a belt clip having an 8mm separation distance. In fact, it is very often the case that the slight separation yields a higher power density than direct contact. This is of course due to the wavelength of that particular frequency.
Nuclear isn't evil at all. Heavy water nuclear reactor are however, stupid. Totally stupid.
There are several nuclear designs which produce a fraction of the waste, cannot melt down and are non-proliferation. I expect that last item is exactly why they are not used.
We do not need more heavy reactor plants.
Have you ever used a Mac?
They are famous for not giving two F's about compatibility from a previous version.
Windows on the other hand has always been plagued by this hanging on to compatibility. So much so that there OS is huge. Much bigger than it needs to be.
While I agree that this time around they are all very, very slow, it is important for people to understand that in the US, the phone manufacturers cannot just "release" new software when ever they want.
Nearly all carriers in the US are members PTCRB. When you update the software, you need to test and re-certify it. You need to update your SVN number as well.
This takes time.
Grants, not as long as it is taking. Unless of course, there are some fundamental issues which cause the protocol tests to fail.
Seriously, why is this guy's comment flamebait? Apple does this. They move billions of euros through Ireland to avoid paying any taxes.
I find it curious that so many Slashdoters have no problem when a company uses all the advantages of society and yet refuses to contribute to keeping the society going. In this case, literally racking in billions upon billions in profit while barely contributing to the tax base.
Why do you think this is a good thing?
I work for a small company. We have only about 80 people. So, while we may not make as many jobs as Apple does we do pay our taxes. We also still have a profit.
Hey, you guys remember that time that the US government was so corrupt and greedy that they allowed the two worst companies in America to combine into one mega company and literally destroy the internet as we knew it?
That was awesome.
Wow, that app must be exactly like Harry Potter's marauders map! Cops automatically appear on the map, no matter what. All cops too. Not just the ones reported by people in speed traps.
I hope the terrorist don't get a hold of this!
And...is China tiny?
The internet in China is way faster on average than in the US. And the just started!.
Americans seem to be unable to wrap their heads around this simple fact...
Without a strong broadband service, your entire economy will be overtaken in time. You people do the same thing with education. All these stupid morons with no kids...derp derp, why should I have to pay taxes for education derp derp?? They never seem to understand that an uneducated country is a dead country. A country of mcdonalds workers.
The reason is greed. Pure and simple.
I travel to China all the time for work. Even remote places in China have faster internet than the US major cities. China, in case you didn't know it is also pretty damn large.
Where the hell in Germany are you living??
I am in Essen and paying 48€ with unitymedia.
I literally didn't know it was possible to get that shitty of a connection here. At least in Essen, I am pretty sure you would need to special order such a crap connection.
Historically, things always get much, much worse before the 99% freaks out. Very seldom do the ruling class give up any power and improve the situation for the masses to relieve the pressure pot.
Just like the 99%, they also repeat the same mistakes over and over.
Seriously, these guys are total fart blossoms.
I cannot believe the things they are able to say out loud with a straight face.
25Mbps/3Mbps is barely even usable.
Every time I visit my folks in the US, who have 25Mbps/3Mbps I find it unbearably slow. They pay like 80bucks a month for that ridiculous "broadband" connection. 80Bucks!
Meanwhile, I may 48€ per month for 150/25Mbps. That includes TV and phone too.
Seriously, how the fuck can you guys stand it? Especially when ever tech company is pushing their stupid cloud services. How are going to use a cloud service with your ridiculous dialup speeds?
How are you going to watch HD Netflix? Let alone 4K. Forget about it.
