indoor positioning system android application - Android Q&A, Help & Troubleshooting

my final year project proposal is " indoor positioning system based on smart phone", and need to make a software for it ..how can i solve it ..any idea :laugh:

I suppose the first place to start would be seeing if you could use Wi-Fi or Bluetooth. You may be able to write a program that would tell you where the phone is in relation to the Wi-Fi router or a stationary Bluetooth device.

[Q] Triangulate GSM cell towers for location

Hi guys,
Have you ever heard about the location search function on certain carriers?
For example, X wants to know where Y is, both doesn't have GPS or internet function. X sends an sms to the carrier to locate a number.
Y then receives an sms for permission to allow X to know his/her location. When approved, X receives the location of Y.
I was wondering if this can be done on our phones to know our own location?
Benefits:
-saves battery (not using data or GPS)
-saves time (don't have to search for satellites)
I found out on how to calculate our longitude and latitude from here:
http://stackoverflow.com/questions/...triangulate-gsm-cell-towers-to-get-a-location
Maybe when we get our longitude and latitude, we can trick our phone by thinking it is a GPS data, allowing navigation apps like Google Maps to point our location.
Any devs wanna work on this project?
Lol just turn off your gps and use mobile internet in gmap. You can see tower based location in map

With what I suggested, you don't need internet
All you need is a normal GSM connection.

without internet I think its not possible because gmap need internet connection to load the area. Latest gmap has the Offline Map feature where we can preload an area. When we visit that area,we can get turn by turn navigation without internet

Okay. Assume we have an offline map like you mentioned above.
What do you use to determine your location for that turn by turn navigation?
Gmaps uses GPS or internet to determine our location.
But our carriers determine our location from the strength of tower signals around you.
Open the link on the 1st post for a detailed explanation on how it works.

It doesn't use internet because it only uses the coordinate of nearby towers and their signal strength to calculate our location.
Hope any devs can make an app to read tower information, calculate coordinates and point it on a map, tricking it into believing it comes from GPS or data connection.

Sygic does the trick

In certain locations, gmaps support offline maps too.

Thanks, I'm gonna try it.
Doesn't work with Sygic. It still needs GPS.
Is there any way of making your phone think that data from GSM triangulation is coming from GPS?

Samsung pocket GALAXY wifi issue

Hello everyone,
I am running android 2.3.6 on my pocket galaxy.
Whenever i keep my wifi on for sometime and keep my mobile aside ,i doesn't connect to internet as soon as I again pick it up. Though it shows that it is connected but i have to switch wifi of my mobile off and them turn it on again. There is probably no issue with my internet connection or router because my tablet and laptop doesn't show similar problem that use the very same wifi signals for accessing internet.
Secondly,lets say i went out of home along with my mobile into an area where i don't get the wifi signals of my router and then came back,while wifi was on, mobile would not connect itself even after ten to fifteen minutes. I don't know whether there is any particular time interval for every mobile to scan for wifi but i guess it must be not more than two to three mins once you don't have signals.
Please tell me ,is it a hardware issue or software issue and how to fix it. Would be grateful .
Regards

want WiFi direct !!!

I see wifi direct feature only in viper3d (sadly it not working),,,Is there any mod or patch or something like that for the WiFi direct on android 4.2.2 ???

I think its just a software option.

I also think it is just a soft. option and i think it indirectly use WiFi hotspot/ wifithreding to send a file(if I m right) because there are many software available in market to send file with WiFi hotspot to another phone but there was requirement that another phone has same software which I use to send file like "software data cable"

You will require an AOSP ROM to transfer files via wifi hotspot . Or if 2 or more devices are connected to same network then you can use sense roms also . I will post the app names later, I forgot the names.

Friend I am root box by helicopter, I hope your sending procedure of wifihotspot will working there, if you suggest me a Software i don't like to send with softwares because it is requrinent that others has same software (if this requirement is not necessary with your suggested Software, than I glad to know that)....
I also successfully connect 2 phones with same network (one on wifi and other on hotspots) but don't. Know how to send file like wifi direct....

Use https://play.google.com/store/apps/details?id=com.floriandraschbacher.fastfiletransfer
It will not work on sense roms. You just have to share files like you do with bluetooth, just choose fast file transfer instead. It will enable your wifi hotspot and generate a qr code and a link. You will need to connect the other device to this hotspot and open the generated link in a browser or scan the code. You don't need to install this on other devices.

Why can't I enable GPS without agreeing to some data downloads?

Just got my Z2 and I'm practicing in offline/unregistered mode because I plan to use the phone without Internet during a trip abroad. Got OsmAnd installed with maps etc.
Problem is, I can't enable GPS without agreeing to some data collection on me:
The device will download information about your current location to improve the performance

"The device"? Is this some SONY crap, or Google's Android? How will performance be improved?
How do I disable this if I don't want my location sent to some random server? If I Disagree, GPS stays disabled.

In the Location menu in settings, set Location mode to "Device only", you'll notice if you select "High Accuracy", not only does it say it'll use Wi-Fi and mobile networks to determine location, it'll also have the notice about data usage pop up, Device only means it will solely use GPS to determine location.
Probably to help get the initial fix for your position?

Imagine High Accuracy mode as A-GPS, using data networks to download GPS coordinates as well as getting your location from IP address location and network proximaty etc
Device only wont use any data networks or cellular information either, try it out anyway, take your sim card out and turn wifi off and go for a walk, see if it works.
It just downloads agps data which helps, making the gps fix much faster. Since this download may charge your service fee, you get the warning. Its nothing about Sony, every phone with gps does that.

G2 mini - very innacurate cell tower location

Hi, I have very inaccurate location based on the cell tower triangulation (in building), it shows me my location to be almost 100 m away outside of the building. (my friends with G2 and S3 has got correct location in the building , when they are on the same place as me).
Please do you have any tip, how to fix it? Or there is nothing I can do with it? (only to buy a new mobile)

cell tower location is always inaccurate. your friends were probably using wifi location. in settings, these two are together called battery saving location. just turn on your wifi and you'll have the right location displayed, you don't need to be connected to the wifi network, you just need any kind of internet connection

Well actually we have both switched wifi off (and we turned off the GPS in location menu). and we have the same net provider. I have even downloaded antennas program, and put it on the both mobiles, they are at the same place and both shows a different location.

GPS is very poor on the G2 Mini, that's probably why.

lol if you turn gps off, your phone just shows the last location it remembers.. also, it is possible that one of you has turned an option on, which enables for the phone to look up wifi location even when wifi is turned off

yep, that would be the reason - their GPS can fix the location even in the building, so the last location is from the building... Thank you for your tips, I will not any more waste your time... Another lesson is learned, next time, when I buy a mobile, I will run a GPS test to be able to return it within 14 days of protection period...
