[Q] Can't an app technically boost signal?

I've noticed when I'm at work, where I get little to no service, when I pull up a web page, or anything else that pushes for data, I get a slight to moderate boost in signal while said tasks are being executed. My problem is that I also get very little service inside my house, but I always have it on the charger close to a window - which does help some. Now from what I've read and understand the battery can actually be pushed to increase signal up to a significant amount, as I've noticed at work, and even while using GPS in what are usually dead zones for me. Now I'm not too keen on how it all works, so I figured I would ask anyways... So finally here's my question - Since I always have my phone on the charger at home, I'm not worried about draining the battery. So shouldn't there be a way for an app to push the battery constantly to boost the signal while the phone is charging? Sorry if this is a clearly dumb idea, I'm sure there's a reason it won't work, but I thought I would throw it out there.

No idea what the duck u r thinking

Just an idea based on observations I've made over the years. Figured I'd get a more elaborate response than that. Like I said, I don't know much about how the antenna works, but I was hoping to find a reason why this wouldn't work.

Technically it's not possible.
Let's keep in mind that FCC has regulations on the maximum output power for each class of devices such as a cellular phone.
Also sometimes a voice communication signal (1xRTT) is not always same level as data signal (EvDO) at the same physical location due to many factors. Also we are not sure when the signal indicator bars are displayed, which signal it's displaying at which moment. That could explain the boost you saw on your phone.
Just keep in mind, a software is not able to modify a phone's signal.

Much better, that makes sense. Thanks man!

Have you tried a signal booster antenna sticker?

You can get them on ebay for about $3 for 6 pack. Many people have mixed feelings about these. As for me, I have one in my Evo. I just noticed a gain of one bar only. Still, one bar is better than none.

There is a reason people have mixed results. It's the placebo effect. There is no reason that covering your phone in metal would help.

Theres a thread on here somewhere about the air rave(sp?), I think it was in general. Guys with bad service at home were calling sprint, and getting one for free. It uses wifi to boost your cell signal.

Wi-Fi is weak

Anyone notices the Wi-Fi signal on epic touch kinda weak or horrible lol. Love this phone just the Wi-Fi problem

Yea I noticed it today... it is kinda weak

No I haven't noticed this. Although there are Los signals that get lost a lot. Try chirs's kernel to solve this.

It shows only one bar on mine but i get full speed(20mbps) from time warner when i do speetest where as evo 3d only shows 8mbps . THat single bars mean nothing check your speed with speedtest.

Signal and wifi speed are fine just the wifi reception is weak for some reason. Im about 1-2feet away from my router right now and im getting only 2bars.

wifi reception on this phone isn't great

My wifi is great it works really good. It might be your router.

Mine always shows very few bars but I can walk out and get in my car and drive around my condo building before Signal Alert beeps that its disconnected from wifi. Looks worse than it is.

I used to use WiFi on my patio and in the garage to stream music with no problems on other phones. With this one it disconnected as soon as I went out the door. Finally did a factory reset as recommended on another forum and it helped a lot. I can use it outside now. Still only one bar, but it works without disconnecting.

What's with all these outages..

I can't believe why this phone goes grey bars and losses signal so much..why is this? Is it the radio?

I would also like to know this since my time frame to return this phone(blasphemy in the GN community) is drawing close. I love this phone phone but if it's hardware related then I will consider swapping it for something more reliable in terms of functionality. I almost bought a razr but was encouraged by some friends that this phone was the top notch phone. I've tried a few suggestions from updating the radio to adding *22899 to my contacts list and updating the prl. Still, at best the dbms fluctuate from 98-82dbm. If this is a software related issue I hope they fix it soon. I'm not too happy with hearing that a planned update would cause the signal bars to appear more than they really are. This would be an attempt to dupe us into thinking that it was only a software issue. You can always check the dbms to see the actual reception unless they muck with that as well. For a google phone the GN seems to have some un-welcomed secrets. Thanks Big Red.

The signal is a software issue, and if it going out for you it is going out for other 4G phones too. Using *228 on a 4G phone also does nothing..

I certainly hope you're right. It's just strange that the signal fluctuates so much if it's a software issue. Almost like listening to a radio station and it comes in and out because of the reception. Just an analogy, nevertheless, one could only hope it's software related rather than having a poor antenna.

I agree with u and ur analogy. I'm pretty nervous myself as I though I had a faulty phone. Fact is, I pray this is software related. I can't fathom having a hardware issue..or keeping a phone so expensive with such an issue.

If it makes you guys feel better, I have no idea if this is what is going on but I know on Cyanogenmod, and other AOSP based roms, the signal bars that are shown reflect your DATA signal. I am not sure if this is true for stock AOSP, but that's how it is on CM and MIUI, etc.
Which is probably why Verizon said they had a fix for the signal bars, probably to make them reflect voice signal.
I know HTC and Motorola phones with sense and blur *inflate* their signal bars by showing voice signal (2G/EVDO) everywhere.

It's more likely a network issue, verizon has been going down recently

[Q]CM9

Why is it I never get full reception on CM9 and aokp but I get full signal reception with Dark side and other roms?

I assume you're talking about the signal bars. I heard it's just a display bug.
Check under settings about and see what your db are, and compare that. If those are still different, then this might be a serious issue, but the signal bars don't mean anything.

Agreed. I have the same issue. but my signal is still the same, if you switch it to display dB value versus signal value then it says the same thing. Im guessing its just a flaw in the XML found in systemui.apk.

Yes i'm talking about the signal bar. I guess Ill keep searching for some type of fix or something.

[Q] Signal Booster

I live in a "dead zone" in a valley. The k3 modem works the best but in my basement there is almost no chance for signal. Is there a script that could be written to boost my signal strength wen necessary? In an ideal world with a toggle. I'm usually charging in this area so battery isn't a concern. I need to study tasker or similar I think for that type of option. Forgive me if that is the wrong idea. I use KT kernel and don't understand all of ktweaker settings and there is so many. I don't know if one will control this option. Ive seen threads about antenna and hardware to install I just didn't know if more power directed toward signal would help. Thanks for any input.

hmmm.. not sure about codes that can boost strength. If there is, please sticky this.. haha
I live in a dead zone as well. There are a few solutions (costing lots of course)
You can look into a device called zboost. Google it and see if its right for you or not.
Hope this helps!

Signal isn't fixed by code. Its fixed by your provider putting up more towers. Only thing you can fix is the signal picture to make it show more bars when you actually have little to no picture. But that would just be a false read and you would still have no signal.

Cell phones are optimized based on how much "power" they can utilize to search for a signal, and how much they should be use after a lock and sustained signal has been established. The more the power phone uses, the more hotter it would become, and the more radiation it would emit.
This is what you see as SAR rating on your phone.
The max power used is normally limited at hardware level too (to the best of my knowledge).
Just giving my 2 cents here

Thanks guys. I was hopeful. Att is the ONLY carrier that will even kinda work. Not like I like I live in the boonies either. Maybe they will add a tower someday. Thanks again.

I had to purchase a 5W booster to fix my issues (my provider paid for it or else i could cancel my contract)
