Hi, I probably sound like a complete noob when I ask this (in all honesty i'm not technologically savvy), but after reading the safety instructions that came with the Touch Pro 2 I have a question. The user manual says the antenna area (towards the top on the back of the device) should not be touched as it will lead to further RF energy exposure and also affect performance/battery life. What I'd like to ask is, is RF energy transmitted only when making/taking a call? Or is it transmitted whenever the device is in use (e.g. when texting, browsing the net, etc. etc.)? It's quite uncomfortable to always avoid touching the top of the device, and I'd be happy to learn that I'd only need to do this while in a call.
thanks for any help!
It has to transmit whenever you send something to the tower. Sending a text message and browsing the internet (requests for things form servers) will make it transmit. Don't worry about it when you are browing or texting, but keep your hand off the antenna for maximum signal when talking.
thanks for the info. Also, the RF energy is too low-level to present a danger to a person's health even if the antenna area is touched right?
Haha, is this for real?
I don't think you need to worry about it.
hint: A phone may emit something like half a watt (=< 500mW) of RF energy, if you're lucky. A Cell Phone tower transmits over one hundred times that (=> 500 W plus). Your average television transmission tower emits maybe a MegaWatt or more (=> 1MW plus).
Which is more dangerous?
Which do folks carp on about?
It also has to "check in" with the tower on a regular basis. Just to let it know you're in coverage area and can receive a call/message/etc.
Still not really dangerous.

Overall, my area has a pretty good signal, but I live in a slight black spot, and my modern house with its foil lined walls does nothing to improve the situation. None of my phones have ever got a decent signal in the hous.
But I have observed a troublesome trend with the new Desire. If I leave the phone lying around on a shelf, the phone shows 2-3 bars of signal. If I make a call, the phone usually holds the call OK.
But if I pik the phone up to mess about with and dont immediately make a call, while I am holding the phone the signal will drop to zero, no service; and it doesn't come back, not until I put the phone back on the shelf.
Could it be that HTC are being too agressive with power management? Or could this be the same fault as has been reported in the Google Nexus?
It is entirely repeatable, to the point that I can demonstrate it to people.
What do other people in weak areas find?
Hi,
Is it exactly the same like the below demonstration of Nexus One signal drop?
http://www.youtube.com/watch?v=qEIA_lMwqJA
So far as that goes, yes, exactly the same.
What he doesn't do is test for less drop if a call is active. The phone appears to try harder to maintain the signal if a call is in progress.
AMAZING. Isn't it. So much talk about so many subjects, but no-one interested in how it actually performs as a PHONE!
This might be related to location of the GSM anthena on Desire and Nexus. Try to move your hand bit more up so you don't touch the bottom back part and check if there is any difference.
I would rather guess the described behaviour of a phone is perfectly normal with all phones under bad conditions. Happened to me with all my phones so far.
does anyone here have one and if so, which brand do you use?
Are you talking about those things you stick on the phone to reduce radiation? Those things are a joke. Nothing you stick on your phone is going to reduce or block radiation to any significant degree. And if it did, it would also affect your phone reception. Remember, cell phone radiation goes right through buildings, trees, cars, etc. A little sticker isn't going to block it.
Those things are just like the stickers that are supposed to amplify your cell signal for better reception. They do nothing, and are just a waste of money. In fact, I wouldn't be surprised if they were the same product, just sold in a different package.
If you want to reduce your exposure, buy a phone with a low SAR, minimize your use, and keep the phone as far away from your body as is practical when not in use.
Just wanted to second that. The information posted is 100% correct.

That can't happen with me. I need my phone with me most of the time. Don't worry - You'll find me in a few years. I'll be the only person on earth glowing green
lol, thanks guys.
I just got worried bc i will be carrying around 2 tp2' now instead of one S) and on one, I will have data running constantly.
Get a bluetooth headseat and keep the phone just within range of it

yep... Bluetooth headset and keep it in your pocket... that way the radiation isn't going to your brain but to your crotch!
PHONE DO NOT WORK THIS WAY!
Mobile phones use non-ionizing microwave radiation and you will NOT get cancer from them.
I don't have internet at my apartment and I don't have plans of getting it anytime soon. I get a free Cricket Crosswave with my job so I haven't really planned on getting real internet service.. I have crap for data when it comes to Sprint. It's a shame that I have to use Wifi on my Sprint phone and hook it to my Cricket wifi just to have data.
Anyway, I know that if I call Sprint and complain they will send me their booster thing for free, but I have heard of people buying similar devices that don't require an internet connection to boost signal. Does anyone know of a solution?

I think I can help you
I have tried to signal booster all it is really is a repeater you put a antenna up REALLY high or at least as high as the cable they give you let you and as long as you are in range of the base you should get better signal this works in theory. I am not so sure it works in real life good way to find out before you buy see if with in a mile or so of your house you can get the signal you are looking for if not then I am not really sure I would waste my time with it I mean you could as long as you can return it. These things are really truly made to just pick up a good outside signal and bring it inside places that well are shielded there not directional antennas or anything that would be able to be aimed (which would work better imo) how ever putting it up high in the air will tend to improve your ability to pick up signal in you are in a low area they are powered which means the SHOULD be able to boost low signal but again SHOULD is the key. Bottom line it didn't work for me and I have what is suppose to be good coverage in my area but.........I don't BTW here is what i tried take it or leave it up to you hope this helped I am not really good at this hope explaining things deal.

i'll probably have to give this a try some time soon.. thanks!
Can also try mounting on an old SAT dish, it can provide a huge gain of signal if you have one lying around, just point it in different directions till you get max bars. Show your signal in dBm if you can for more accuracy. The dish points in the direction of 45 degrees off the plane of the dish.
Remove the black tape that is on top of the actual antenna and you'll be left with a gold copper ribbon which is your real antenna. This help a lot because the black tape is blocking the radio wave that your antenna is trying to receive.
Special use case. I am trying to get a signal when summitting 14ers (really high mountains). The current method is to send a guy up with a Verizon phone and a few other WiFi hotspots and cross our fingers that he catches signal for a few minutes.
I've scoured the web and can't seem to find any information on this. The Wilson Portable seems like it has the right idea, but is clearly designed for a car use situation. Should I be looking into using a Wilson Sleek with a larger external antenna and improvised battery backpack? Or perhaps there is a software trick to increase the power to the 2g radio? I'm really all ears.
I would love to figure out a way to simply slide my Nexus 5 in a case of sorts with a ~3ft collapsible antenna on the top. Would this work? Does it need to be in physical contact with the actual antenna, or could it just be in contact with the backplate?
I really hope someone has an idea on this subject. I find it so hard to search for!
Thanks again,
Matt
Ingress? lol
Yeah.. I wouldn't have much of an answer since with any booster, there needs to be a signal to boost.
I've thought of using your idea with a booster and a portable battery, but have field tested it yet.

I've got a Nexus 5, not sure if we have an external antenna jack or not. A lot of phones hide it under the battery.
You'd want a Yagi-style antenna. There are lots of instructions for making them with stuff like fishing pole tubes and tig welding tubes to make them ultra-light and foldable/dis-assembable for hiking purposes.
http://www.ubersignal.com/blog/yagi-antennas/
Yagi's boost transmit and receive both. They're highly directional, so you have to point them at the right spot.
Get a sat phone. Or climb 14'ers that have cell towers on them.
I climb a lot in the Sierra Nevada and almost always have service anywhere over 13000 ft. They're a narrow range close to population though. If you doing that in the Rockies I wouldn't trust cell service.
Hi guys,
We've just setup our chromecast network. Now with 1 or even 2 chromecasts in the network, everything runs smooth. But if we switch to a bigger network with 3 or more chromecasts, the connection is really hard or won't even happen at all. Anyone experienced this as well? The Wifi is new and quite strong (with additional routers on the first floor, so the wifi shouldn't be the problem).
Thanks for the reply
This is a limitation of WIFI. The more devices you have on a wifi, less bandwidth you will have available. WIFI protocol is using air time allocation protocol because it can talk only with one device at the same time. More devices you have active, more times it will switch between them to deliver all the packages requested. If you have wifi booster or extenders, I would recommend you to grab them all, smack them with a hammer, put them in water, take them out, dry them in the microwave oven, burn them with a torch and trow them in the garbage because that is what they are. Extenders ads latency and packet loss and also is reducing your bandwidth in half before you even have a device on. Do it yourself or contact a professional to install UNIFI from UBNT or similar products. Huge fan of their gear. If you have it properly installed and set-up(not just plugged in) you wont have any problems with any devices not just Chromecast.
BTW, strong WIFI doesnt mean anything. Your wifi is as strong as the weakest device. You can have a wifi that transmits 10 miles, if your other device transmits back only 30ft, it will be 30ft max wifi range even if at 300ft it shows full bars. The best thing to do is add a bunch of AP with the transmit power on the lowest. Keep in mind that wifi 2.4 has only 3 true channels that wont overlap: 1. 6 and 11. If you set them all the same channels they will hurt them self with their own noise floor. If you properly set them up with a spectrum analyzer, to be right at the limit, you could make them all same channel and do cool things like zero-handoff. Performance WIFI requires knowledge and proper set-up not just plug and go.
