Does the GPS function work if you are out of cellular & wifi range?

How does the aGPS function of the iPhone 3G work? Do you have to have a cellular or wifi connection to be able to get a location fix, or will GPS satellite signals-only be sufficient?

Question?
Answer.
If you don't have EDGE, or 3G, how is the iPhone MAP app going to download the map?
It won't, as it can't.
I don't believe they are built in.
You believe right.
This is why Apple needs to let someone build a true GPS app for the iPhone, which you can download the maps to the phone.
Maybe. But this was not the question. The question was, if the iPhone 3G would be able to find it's location even without WiFi and cellular network. And yes, it would find the location. The question was not if it would be able to display that location in the Maps app.

  • How does the Delta functionality works while updating Infocube from PA

    Hi Gurus
    How does the Delta functionality works when you send forecast to the Info cube from the Planning Area.
    As I have weekly based planning, every week we have to update the forecast into the Cube. If I update  every week into the Cube , then the values are going to append  in the Info cube.
    Shall I create ODS in between the Planning area  and the Info cube .
    (or)
    Any other method ?
    Please Suggest.

    Hi Preetham,
    Data Extraction from planning area to infocube usually its supports for full update only, when u r going to load the data from planning area to cube ,it deletes the previous data and u vil get the fresh data, this is the best method performance wise,
    if u want to use the delta functionality u can go for planning area to Dso, Dso to cube, it vil supports the delta functionality, but it vil degrades the system performance,
    regards

  • Does the bluetooth function work with the scanner function on my Photosmart C5550?

    I have a new Dell computer and an HP Photosmart C5550.  I use bluetooth to connect to the print. The printer function works correctly but the computer does not recognize the scanner function. Does the scanner function work with bluetooth?
    This question was solved.
    View Solution.

    Sorry. I hit post before I could elaborate. Not sure what I was thinking. The Bluetooth connection will only support printing. To use the scan feature you will need to connect the printer using a USB or network connection. Hope that explains it a bit better.

  • How does the sync functionality work with large libraries on small devices?

    How does the sync functionality work with large libraries?
    Say I sync 100gb of photos with the new Photos app and turn on sync on a 16gb iphone. Will it fill the device up to 16gb? Can I tell it to limit to xgb so I leave room for music and apps? How does this work? Will it slow down my phone if its trying to sync 100gb across smaller devices?

    "Will the Apple TV now read directly from the Time Capsule?" ATV does not 'read' from the TC. It connects to the Mac and itunes library associated with the Mac. Of course the itunes program can 'point' to a library on the TC. You'll still need to have itunes open and the Mac powered on and not sleeping with the TC mounted to the Desktop to use ATV properly. So bottom line the use of TC just adds one more step to view files on the ATV.

  • HT2433 what does the error message that says " You are logged out because another computer is using this IP address." mean?

    what does the error message that says " You are logged out because another computer is using this IP address." mean?

    Some other piece of network ghardware on your home LAN (Local Area Network) is using the IP address your Mac is trying to use.
    Reboot both your modem and router, or the Modem/Router combo box you have, and all pieces of networking equipment, computers and printers, you have connected to your LAN.
    If you continue to get that error then it is a bug in OS X or you have your Mac set to a Static IP address that is being handed out by the routers DHCP server to some other device.

  • Using an iPhone4 with no Service plan...does the GPS still work?

    If you take an iPhone 4 that does not have a Cell plan at all, and use it like an iPod Touch, will the GPS still work?  Obviously, the assisted GPS portion will not work, but we're looking to use certain apps that measure distance via GPS (specifically, running apps like Zombies Run).  These apps will run on an iPod Touch, but the absense of a GPS chip means that certain features are disabled or not quite as accurate.  We have no intention of ever purchasing a cell plan for the phone, we're just looking to get an iPod Touch with GPS built in to it.

  • Does Home Share only work when you are at home?  Or once you've shared will the music stay on the computer you've shared it with?

    I want to use Home Share to share music in i-Tunes between my desk top and my laptop.  Does it work once you're not in the same house?

    If you use home sharing to transfer music to your laptop, it stays on the laptop and you can take it anywhere.
    Look at Understanding Home Sharing:  http://support.apple.com/kb/HT3819  where it says "With Home Sharing, you can stream music and video from one authorized computer to another, or simply drag music between computer libraries. You can also choose to have iTunes automatically import purchases you make on any of your Home Sharing computers to your own library."

  • Why does the GPS not work with other programs?

    It works ok with Blackberry maps. But there are about 5 or 6 programs that I use that will not lock GPS. The one that really florred me was the camera. I sit there and sit there waiting for the gps to lock on (turn from red to white) and nothing happens. We all know that google maps doesnt work (it only will use cell towers. After the STORM disater you would have thought RIM would have been a bit more careful with thier OS's. Hope they get a fix out soon.

    Hi Barbara
    Thanks for the response.
    I updated to Mavericks (10.9.3) and the organizer now appears to work.
    However, it is extremely slow in previewing photos that were already on
    the Mac and does not appear to be able to download photos from a Canon
    5DIII. It appears to start but then spins and spins. It ran overnight
    and was unresponsive this morning.
    Do you have any ideas as to what to do to make this work?
    Will

  • Does the gps still work iphone if not connected to internet

    so some kid took my iphone5 out off my hand and passed it around at lunch and now i dont know what to do i put it in lost mode then it went offline can i still find it even when its offline

    The GPS works if the phone is still powered on, but if there is no internet connection, either cellular or Wi-Fi, then you will not be able to track it. If you did not have a passcode on the device, then change the passwords on all of the accounts you have on the phone. More than likely the device is powered off, which is why you are seeing the offline message.

  • Can anyone confirm that the GPS function works at all on the 4620L?

    Our small team of IT and GIS professionals have been trying all week to get the NMEA GPS data off of the Jetpack 4620L.  We would like to use this data to track the location of our Police Officers in the field for their safety. We have ESRI mapping software which can handle the reading and display.
    http://www.nvtl.com/products/mobile-broadband-solutions/software/gps-over-wi-fi/
    According to this document, there is both a separate GPS and a "tower triangulation" GPS over wifi
    http://www.nvtl.com/files/8013/6502/3173/14915267_Rev_3_VIEW_Datasheet_MiFi_4620LE_VZW.pdf
    We have so far not been able to get coordinates from either.  Nor have been able to find any evidence of the function working for anyone.  We'll have to stop trying unless we can find evidence the function works per the guidebooks instructions for somebody.

    Actually, I have a friend that uses the GPS feature without an issue.  Of course, his system is not as sophisticated as yours I'm sure.
    However, he uses it all the time as he travels all over and loves it.  He just enabled it in the Advanced section and followed the directions to connect it to the tracker and that was it.
    Not sure if you noticed the port number in the section where this is enabled but it may be something to look into.  I don't know much about GPS but thought I would share that.

  • What does the setup() function work?

    i am writing a basic program to make a shape and would like to use the setup function. Can anyone point me in the right direction.

    Can anyone point me in the right direction.No, because I have no idea what class this method is in.

    There are hundreds of classes. Find the one you're looking for and click on the setup() method. It will tell you what it does.

  • Will the gps still work when you have no wi-fi or cell service?

    just wondering if the gps is stand alone?  so i can use it as a chart plotter on a boat.

    Yes you can use GPS on a boat. You must download the charts of the area you will be sailing in to your iPad before leaving. Keep in mind that the iPad is very hard to view in bright sunlight.
    Of course my response assumes you have the correct iPad model that has the GPS hardware. The wifi-only iPad does not contain GPS hardware.

  • How does the SignatureClear() function work?

    Hello everyone:
    I have read Javascript for Acrobat API Reference (8.0) and I'm still wondering how SignatureClear() works. Is it possible to clear a signature field with this? How? It is said that you can not work with it in Adobe Reader... but I have seen some other functions working despite of the Availability column: is it possible to use it in Reader?
    Code examples will be very appreciated.
    Regards,
    Javier

    Javier
    I have not reviewed thew API documentation, but I can comment...
    1)  To "clear" or remove a digital signature, you need to have access to the "private" key (digital credential\certificate) that was used to generate the signature.  This means that typically, only the signer can remove their own signature.
    2)  You cannot sign a PDF document with Reader, UNLESS the PDF has been "reader extended" with the "signing" permission that will enable the ability to sign a document with Reader.  A PDF can be extended with LiveCycle Reader Extensions (server product) or with Acrobat Professional.  I have nottried it myself, but I would assume that the "signing" permission would need to be enabled on the document to allow Reader to remove (clear) the signature, assuming agaion that Reader had access to the private key used to create the signature.
    Hope this helps.

  • How does the TS_SeqFileSequenceNameExists() function work?

    I am creating a TestStand Sequence file using CVI and would like to know the correct syntax for using the TS_SeqFileSequenceNameExists() function.
    Basically what I'm trying to do is add a sub sequence to my file and if the sequence name already exists, change the name. So the code looks something like this:
    if(!(TS_SeqFileSequenceNameExists(seqFile,NULL,subSequenceName,&myTempVBool)))
    //sub sequence doesn't exist... add it
    else
    //subsequence name already taken, change the name
    Thanks,
    Marek D.

    Hi Marek,
    you're logic is a little out - in your example code you are testing the error, not the bool "myTempVBool"
    so something more like
    (TS_SeqFileSequenceNameExists(seqFile,NULL,sub SequenceName,&myTempVBool));
    if(myTempVBool == VFALSE)
    //sub sequence doesn't exist... add it
    else
    //subsequence name already taken, change the name
    NOTE :
    You need to rename the object BEFORE you try to insert it. Have a look at the help file on
    SequenceFile.InsertSequence where it says about the sequence must not already exist in the file. (Also don't forget to release the clone object when you've finished)
    Have a look at your other question on "How do I change the name of a sub sequence using CVI" , I've included an example there which shoul
    d help you out.

  • Does the Resume Function work in an Aggregator Project?

    I hope this is a simple yes or no question.  If I use the aggregator to publish several SWF's, will i be able to use the resume function that is built into Captivate's TOC settings?

    In my experience no it doesn't.  The Self-paced Learning bookmarking is more designed for single projects, not aggregated projects.
