Isn't GPS by definition line of sight. i.e. your phone needs view of the sky to get a a gps signal or satellite lock.
I have seen multiple posters saying that they are in their house or office building and not getting a lock or signal. Unless you are by the window or skylight, you shouldn't be able to get a signal by GPS alone. The only location information would be gotten from the network.
If people are having trouble getting location lock 'inside', doesn't that mean that there is a location problem in general, not just a gps issue?
I am definitely a noob, but I have been using GPS since the technology came out and my general understanding is that without a view of the sky, you will not get a signal. Or am I missing something?
Its radio based not light based so it will go through some materials. For example, I get sat lock in my second floor but I cannot see any sats downstairs.
Sorry, nope!
See this link:
electronics.howstuffworks.com/gadgets/travel/gps.htm[/url]
In the second paragraph it states that you need a CLEAR view of the sky.
On this link it explains it even further stating that NO GPS reciever is designed to work indoors.
gpsinformation.net/multipath.htm[/url]
Further, satellite TV isn't light based. But it still needs to be outside so that it can get reception from it's satellite. So your statement about it being radio based rather than light based does not answer the question.
Anyone else?
I'm not a GPS expert but I used to get a lock anywhere with my G1. W/O using network so yeah, this GPS officially sucks.

Certain radio frequencies, including those used by the GPS satellites, are considered line of sight. That is to say, to get a good signal you need to have a clear path to the transmitter. Some radio frequencies actually bounce of a layer of the earth's atmosphere and can travel around the world, and are therefore not line of sight.
If a receiver is sensitive enough and a signal is powerful enough (and depending on the frequency), a signal can still penetrate some degree of cover, so it's possible to get a GPS signal indoors, but as you mentioned, it's usually when one is close to a window. Some GPS receivers are terrible unless you're well out into the open, some can pick up a signal under tree cover.
GPS satellites are something like 12,000 miles above the earth, so by the time a signal gets down to earth it's not all that powerful. Radio power dissipates over distance just like any other form of energy.
You will get the best signal with a clear sky view, but basically modern GPS receivers are now also able to work off reflected signals, as well as the very faint signals which may leak through building walls and so on. A relatively high number of signal errors just translates into reduced accuracy.
Furthermore, satellite-based GPS can be "enhanced" through short-term inertial tracking. Most in-dash nav systems do this (my Suburban will sometimes show a "GPS" icon with a slash through it, and then it relies on inertial nav until it gets a signal again). Your phone can do similar things with the tower signals and perhaps even WiFi SSIDs to help your sat-GPS cope with suboptimal conditions (and it ought to be able to use inertial nav via the accelerometers, but I don't know whether it actually does this).
If you want very high-res GPS, you still have to be outside with one of those backpack-mounted rigs. (A friend of mine does GIS and surveying, and under the right conditions they can get centimeter resolution with those.)
Satellite TV isn't a good comparison for many reasons. First of all, an audio/video stream is a gigantic amount of data compared to the relatively simple timestamped pings that GPS satellites emit. Second, there isn't any demand for electronics manufacturers to provide hyper-sensitive reception: mounting antennas on a roof or exterior wall (or in the case of something like XM, on top of your car) is fine with most people.
I've noticed that my recently bought St18i is kinda strange during calls.
After just 30 sec I get headache and warm around the ear exposed to the call.
This thing didn't happen with Htc diamond 2. I just can't use the cell close to the ear.
Previously I used to get this kind of sensation after at least 1h of continous call.
Instead with this phone it's enough just 30 sec..!
So I was wondering, does anyone here have experienced this kind of issue?
Hello,
That depends on the band you are using and how far is the tower.
The higher the band and the more far is a tower - the more power it will emit.
These days you should always use wired hands-free device as we are getting more and more electrostatic load and various power wavelengths.
I doubt your unit is emitting more, they all undergo checks and tests, unless you bought it from black market Indian makers.
It's natural that the phone and the area around it will get warm during calls, but it should not be cause of headache.
All our cells and atoms are vibrating, we always disturb it with various types of frequencies going trough our body.
Take care.
Well I'll make more investigations about this matter, I want to check it with EMF meters.
Who knows whether an EMF meter is enough or it's needed also a gauss meter...
I have a Ray in USA (unbranded st18a) and I don't have these issues. The phone doesn't even get warm on two hour phone calls. Worth noting is I have excellent reception where I am usually. The phone really shouldn't get warm, especially enough to feel against your ear!
i know this have been discussed before but there is still no solution.
here s my problem: wifi signal drops suddenly when i hold my phone. ive done sevral speed tests. These tests confirm that holding the phone results in a really bad wifi quality. I ve tried eveything.
does anyone have any ideas? even if its hardware moding
thx
+1
Sad to say, in my tests, by tightly holding the phone, especially at the bottom right, the signal strength reduced by about 20dBm.
Sent from my XT910 using XDA
this really sucks since this phone is pretty good and so far its the only BIG problem i found. and no solutions....
Must be a random problem. I have the RAZR and RAZR Maxx and neither has this problem.
For me, on 2.3.6 wifi signal was low, especially taking phone by bottom, but on ICS, both t-mobile ics and latest eu ics, wifi signal is very improved. Hand issue remains, but signal is for me stronger.
well i guess im just going to wait for stock ics update and hope it improves but im guessing the problem wont disappear since this is clearly a hardware issue. and if this is random then im very unlucky
When software fixes a radio that software usually just makes the signal-strength meter show signal that's not really there.
There are apps on Play that "fix" all kinds of radio problems by installing signal-strength icons with the low-strength indications set inaccurately. It *looks* like more signal, but it's the same low signal you had before.
Signal strength has almost nothing to do with reception anyway. Signal/Noise ratio is what's important, and there's no meter for that. One bar of signal in a very RF-quiet area, is much better than five bars in a computer data center.

I have no wifi issues with this phone. The GNex however was unusable at 30 feet from a high-powered Hawking WAP, or an Apple Airport Extreme WAP.
If you have a plastic case, try removing it. Some cases are made with recycled plastic and are infused with conductive material that can act as a Faraday Shield, blocking part of the signal. Easy test, costs nothing but a few seconds...
yea i already knew about the plastic thats why i bought a rubber case. I have to say it helped a little but didnt fix it. the problem is still there.
thx
Haven't seen any problems with my wifi, although I mainly use the 3G simply because I have 4 GB of data a month and I will never use that much when I'm out around town.
If the problem occurs when holding it a certain way wouldn't the simplest solution be to not hold it that way, also be very aware of any metals between you and the router as metals block radio signals, how old is your house, if old enough maybe lead paint, unlikely but just throwing all possibilities out there.
thx for your help. i didnt only test this at home and as for holding the phone im used to hold it like i hold all phones and its pretty annoying if i always have to hold it differently if i want to use the internet
Have you tried the free Play Store app, WiFi Analyzer?
This will help you find out what works/doesn't as it provides more sensitive strength measurements from the chip. It's handy anyway, since it shows WAPs that you aren't connected to. yet.
It's quite possible that your antenna wire bounced off the connector. An insignificant drop of an inch could do that if it was never seated correctly. It would likely operate in a degraded capacity as a result. If you're OK with cracking the case open, that's something quick to check.
How long have you had this phone?
I have never heard anyone complain about the Razr's WiFi reception, so I suspect this is something unique to that phone right there. What is your idea of poor reception? 100 feet, inside, is the practical limit. 300 feet in an open field. Metal wall studs, sheet metal siding, all of these will stop radio waves dead.

Then you haven't been listening. The RAZR is universally acclaimed to have the worst WiFi reception of ANY device since 1999.
im ok with opening it... i actually opened it a couple of times and removed the battery but idk what to look for since nothing is labeled i dont even know where exactly is the wifi ship and antenna. i tested this as close as 6 feet from my router when i leave it on the table i get full wifi signal and speed test at max then i hold it and try... wifi signal goes down and speed test at 3/4 max speed...
thx
It's possible that I have an extraordinary phone then. I decided to compare.
My phone is seeing -60dbm from the Hawking extender that I'm closest to, which is about 20 meters away, behind three stick-frame (pine 2x4 studs, sheetrock) walls. The reading varies dramatically, depending on where I put it on my desk. So let's see what some other WiFi devices do...
My MacBook reads -58dbm. My iPad2 reads -59dbm. An HP Envy 15 reads -65dbm. And a Moto Atrix2 WCS (With Cracked Screen) reads -61dbm.
A transfer of 200MB ("random" data created via linux: 'dd if=/dev/random of=200mb.dat bs=1048576 count=200' so that compression algorithms don't skew the results):
Razr (6.12.79 ICS Black Widow): 9s
MacBook (Lion): 6.5s
iPad2: 10s
HP Envy 15 (Ubuntu 11.10): 7.5s
Moto Atrix2 WCS: 10s
I didn't repeat the test, and that is a busy WAP, but the results are what I expect for battery-operated devices. I also expected the ipad, atrix and razr to lose the race, since they have relatively slow storage systems, which have inherently poor write performance on files of this size (200MB won't buffer at all).
The WiFi cable will look like a white or black wire with a gold junction on the end where it meets the motherboard. I would expect that if you've had the phone open, you would definitely notice a wire hanging loose! I doubt that's the problem, but that wire is a coaxial shielded cable - like on cable TV only really tiny - and you can do all kinds of DIY replacement antenna stuff eg, adding an external jack so you can "beam" WiFi a mile away using a hacked Pringles potato chip can.
I actually think the problem might be RF noise in your environment. Florescent lights (CFLs), computing equipment, HVAC compressors, and motors can effectively "jam" WiFi signals, causing packet transmission failures to increase rapidly as the distance from the WAP increases.
We have a Fluke RF analyzer here, and our WiFi setup is quite good as a result.
Does anyone know if the Razr is unusually susceptible to RF noise? Maybe noise that the Razr generates from the motherboard/CPU/radios/BT? I'm not equipped to test that.
---------- Post added at 09:15 AM ---------- Previous post was at 08:29 AM ----------
Do you have other devices to compare the Razr to?
Did you try pointing all the rubber duck antennas on the WAP straight up?
I just checked an iphone, another ipad, another Razr, and a Dell laptop, and my boss's Razr was technically the winner on signal strength and transfer speed, but let's call it even. There are too many variables, and statistically significant benchmarking is beyond the scope of a forum comment.
The Razr has typical WiFi performance in this environment.
Thank you very much for your post. I did try with the desire z and the evo 3d which are doing jist fine wheather i hold them or leave them on the table: both signal and speed test are amazing compared to the razr (if i hold it). If you could tell me where the wifi ship and antenna are located (a pic maybe) it would be great because when i open the razr all i can see are metal plates everywhere probably for cooling. I dont understand what you mean by pointing all the rubber duck antennas on the WAP...
Thx again
I haven't had a Razr open yet. Even after dropping mine from a motorcycle and watching it slide into a ditch with an inch of water in it. Tough li'l bastards...
The WiFi antenna cable and connector are probably under one of the metal shields.
Most WAPs have 1, 2, or 3 "rubber duck" antennas that you can move to maximize the signal lobe pattern. You can use the WiFi Analyzer app to adjust them, but be prepared to walk a lot...
Others are just a box. The only one of those that *I* know of that works well is the Apple Airport Extreme. The Netgear Wireless-N HD, which is very highly rated, is a P.O.S.: it has a narrow, elongated lobe pattern, and if you're in that narrow lobe, it works REALLY well. If not, you'll be lucky to connect to it. Two people standing 10 feet apart, and one can have great service while the other can't even get an IP address.
The fact that you have other devices working well, and you sound like you've done this quite a bit, I'm guessing you have a problem inside the phone itself.
I manage about 200 phones here, and I haven't heard one word of complaint about WiFi. 3G/4G service? Yeah, lots of complaints about 3G/4G from people out in the woods or working in a valley.
These also work well as a WAP (tethering). We have a few of the Personal WiFi devices - a handheld that converts 3G/4G to WiFi for up to five users - but most people prefer this phone for that.
My old DroidX has a better WiFi antenna, but that's an exceptional phone with only one core: I spit on it. Ptui.
Seeing as being a module developer would involve developing both the hardware and the software, basically giving you almost total control over what you can make (within the constraints of the MDK itself), what kind of module would you build?
Open discussion for anyone really, dreamers and doers alike.
If I had the knowhow and the materials to do so, I think I'd build a solar-charging module to attach to the phone (possibly removing the charger/USB cable module?) so that the phone can be charged on the go.
I'd stick w/ usb charging/jtag module ... Phone's memory blocks would be laid open should one combine the two into a single module option. Solar cells good idea but they take a lot of surface area to generate a substantial/adequate amount of power to run device. I'm interested in seeing the mdk to know what kind of parameters we might be working with either way.

When it comes to Solar cells, I honestly hope that this actually inspires the development of solar cells that are transparent - much like the capacitive layer on touchscreens today. That way, the solar cell could cover almost the entire front of the device - and that way not only act as a source of power, but also as a replacement for today's Ambient Light Sensors (what is the abbreviation for that? ALS doesn't come out right...) - since a solar cell could measure the entire amount of light shining on a device, and not just the amount of light on a small area on the fascia, it would be a lot more accurate. Plus, while you probably wouldn't be generating energy while using your phone in the sun (I'm thinking of the law of conservation of energy here), it would make battery life much better, not to mention much more steady, because the brighter your display would have to be, the more energy it would be getting - and that's assuming you're using it constantly, and, oh, I don't know, putting it down to enjoy what is probably beautiful weather at that point. Unless you put it in your pocket, the way I usually do...
My initial response could prove false in some short span of time. I read http://inhabitat.com/researchers-bu...00-times-more-powerful-than-conventional-pvs/ and albeit they have their challenges, making thinner, smaller cells that are more efficient seems plausible. I love research & tech

Instead of a phone id be happier if this project spawned a new class of android devices (not tablets not phones) that with modules could be more standalone camera or camcorder like (maybe this is actually backwards thinking but illustrates we dont have to stick to our current notions), or have more sensors (really just throwing out star trek ticorder) to be used in scientific applications (eg geology, biology, etc, in mind more field work type situations). Maybe scanner, projector, 3d camera, better speakers, sylus/no stylus, stylus capable screen. Different cameras (infra red or whatever more in line with idea of device being a gadget)
I'm actually thinking that this is where this project will actually go. At the very least it'll be a device that you can transform from your "everyday"phone into a specialized powerhouse built for [insert your abstract scenario here] and back again. As I see it, they're bringing the flexibility of the Android OS to similarly flexible hardware. So I think you've got the idea that they're running with, that this will eventually become a "build your own ________ powered by Android" project, not simply a "upgrade your phone pieces" project.
Sent from my DROID RAZR using xda app-developers app
Yes upgrading phone pieces immediately sounded like a cool idea but probably not immediately pratical (maybe not yet). A device that can become a more specialized device through hardware offers a broader approach that can in the end include upgrade modules being practical. Laptop docks for android phones is similar but wasnt avaiable for all devices. If recall on the droid x2 the kernel and ram was not capable of supporting a moto dock option. Even if this were to expand to a specialized hardware module more like a peripheral, universal support would be difficult. I think all the OEMs would need to get on board. I dunno.

That wouldn't be good. Solar cells don't CREATE electricity when they are hit by light. They TURN light into electrical power, and it couldn't be otherwise as energy cannot come out from nothing. Photons are absorbed by electrons, which detach from their atom and start moving, generating a current, and the ideal solar panel should have its electrons absorb all the light and let no light back: it should be completely BLACK. Transparent (or white) ones would generate no current.

I don't think you understand what I'm saying, I know energy isn't created, and I understand the concept of solar cells - that's specifically what I was referring to when I said that you wouldn't be able to use it in the sun and charge it like that because of conservation of energy - because otherwise there would be more of an imbalance - it would be charging, and shining out about the same amount of light as it is receiving. Of course, stupid me forgot about UV and infrared, which negates that part of my argument . What I meant was that I was hoping that some day there would be a solar cell that could be on top of a screen, and you could still the screen. One option would be semi-translucent - the screen would just have to be tuned a bit brighter, which wouldn't be a problem, either, as most of the light that doesn't make it through the solar cell would be re-captured as energy anyway. The other option - the ideal one - would be a solar cell that would only transform light landing on one side. This definitely wouldn't absorb all the light because of the law stating that light can go back the same way it came, and when I think about it, it probably couldn't work at all, but who knows what science will provide us with in a couple of years - there have been surprises in the past...

At the current state of technology, that would probably be the best option (plus maybe a bit on the bezel, but depending on the efficiency of the solar panel, that could just be a waste) - We don't have any (semi)-transparent solar panels AFAIK, so they have to be dark like that, so yes, at the moment, the entire back of the phone being a solar panel would probably be the best option.
You mean something like a cell absorbing light coming from side A and letting through light coming from side B? Then sorry, I didn't get it .

I wouldlove to have a pocketable service monitor that has a wide spectrum analysis capability, is frequency agile, and has HEMPT devices in the RF measuring section for ultra low noise figure, high gain, good IP3 and selectivity.
You can exclude the generate function, I prefer a device I can take screen shots of signal paths, attenuation, spectrum purity and bandwidth of measured signals, and be capable of printing the output to a printer via Bluetooth or even WiFi.

Research and such
As a budding computer engineer at MTU, I can see this being used for specialized research devices. I can also see somebody building a digital oscilloscope and logic analyzer as modules. No need to get these super expensive bench devices when I can whip out my phone, plug in the wires, and open an app.
I'm nowhere near being an engineer/programmer/etc., but I saw a dongle somewhere a while ago, maybe on Kickstarter, which was like a virtual credit card. You'd plug in which ever card(s) you wanted into the little dongle through your phone via Bluetooth or NFC or something, and all you had to do was swipe the thing over the credit card reader strip on a typical point of sale reader; somehow it created a magnetic field (magnets....how do they work?) and the field replicated the information on your credit card such that it would complete the transaction.
If there was a small module for this that you could plug onto the Ara 'skeleton' which made having a separate thing on your keyring unnecessary, I think it'd not only be a neat feature but also something very practical which might also speed along the use of your phone as a method of payment for goods and services. There's a few different competing NFC services but no universal standard to encourage wide-spread use of NFC (at least not here in the U.S.), but everyone takes cards these days.
Like good ol' days!
Now here is the idea:
*I go to a store.
*I BUY an app/game CARTRIDGE :laugh:.
*Plug it in my ara.
*Enjoy!
Yeah yeah those environmentalists out there will say "why more plastic garbage?" But just think of it like this:
*If the module has inbuilt memory then my phone's internal memory (oh! so precious!) will be saved.
*The apps/games can be as memory hungry as they want to be.
*No more TIME-WASTAGE in downloading GBs of game data.
*People will feel better when they get a piece of hardware for their money!
*Guys from the 90's can showoff their cartridge collections once again in a modern way!
I am very much interested to use such cartridges one day on my ara phone and I will be glad to help anyone who is interested in taking this idea further!
Hit thanks if I helped you!
@gautam360: Single screen Nintendo DS! xD
Not too awe inspiring, but something I would definitely use: USB/Ara Module combo. When on the phone, it mounts just like an SD Card. Slide it out, plug it into a PC, no different than a Flash/Pen/Stick/Thumb/WHATEVERwhocares drive. Formatted as something cross platform. Form factor designed so that you physically can't mount both ends simultaneously.
I would also probably make use of a WiFi Direct module and an IR Blaster module.
At least at first, I expect we will see a lot of modules similar to what showed up with Handspring/Springboard, then a bunch of audio/DJ type stuff like you see for iOS, then more scientific/industrial applications (thermal imager? stud finder? voltmeter? oscilloscope?). Maybe Sound Blaster could make a comeback... Amazon could release their barcode scanner in module form... OneTouch diabetic blood sugar sensors could scan your levels every time you pick up the phone... ThinkGeek could sell an Ara module version of the annoy-a-tron... so many possibilities.
I would use a light meter, that would be nice. Also a Digital Multimeter...

It's not grey at all. It's too low energy to interact with bio-molecules. I would suggest that as it's well under the visible and infrared spectrum, it's safer than a flashlight on your arm.
No hazard - stop reading paranoid pseudoscience "reports".

It's pretty well explained on Wikipedia.
" In 2011,*International Agency for Research on Cancer (IARC), an agency of the*World Health Organization, classified wireless radiation asGroup 2B*- possibly carcinogenic. That means that there "could be some risk" of carcinogenicity, so additional research into the long-term, heavy use of wireless devices needs to be conducted."
The truth is we don't know for sure. These technologies have not been long enough for us to say whether they are 100% safe. Potentially they could increase the chance of getting cancer. At the moment, no consistent evidence supports that.
However, if I were you, I would still avoid them where I could. You just need to work out whether wearing this thing 24/7 produces enough benefits to outweigh the potential risk.

Wireless radiation means nothing if you talk about healt danger, due to very different energetic content in different wireless connection type...

I recently picked up a Gear Live smartwatch which is my first wearable and even though paranoia still creeps over me from time to time I realize that I'm surrounded by all kinds lovely, cancer-filled death waves pretty much 24x7 anyway.
That said I tend to take my Live off when I'm at home and I take it off when I sleep to let it charge overnight but these behaviors are purely out of habit and necessity.
