Help requried in a software project regarding signal strength and tower ID

I am the Student of FAST (Foundation for Advencement of Science and Technology ) Karachi,Pakistan.
I am doing BS in computer science form here. { final year ( 7th semister ) }
currently I am doing a software Project regarding mobiles.
the main theme of my project is[b] to locate a mobile in an area without using the GPS technology .I have thougt to do it with the help of signal strengths and tower ID's of neighboring towers. With the help of these two things I will make some mathemetical calculations {for example triangulation or something else } to know where is the mobile at this point in time.
Initially i would implement it on client side .
are there any APIs that can tell at least 3 stongest cell IDs and their respective signal strengths from which mobile is getting signals; be useful to me in this regard !
for this i need your help ,to guide me how to move forword with this project
I am sure you would be kind enough to help me out
thanks in advance

There is no api for that, that I know of...

Help! Blackberry Desktop Software has encountered a problem and needs to close

I cannot get my Blackberry Desktop to open. An immediate message is displayed" Blackberry Desktop Software has encountered a problem and needs to close." I have done the following:
1. Rebooted
2. Uninstalled and reinstalled from the website
3, Uninstalled, gone in to the program files and removed everything I cou;ld find from Research in Motion and then reinstalled from the website and rebooted
Nothing has worked. My Blackberry Bold 9700 phone is still working just fine but I cannot back it up/
I am not the most technilogically savvy but I'm not bad...Someone please help!.

I suggest this thread:
http://supportforums.blackberry.com/t5/Desktop-Software-for-PC/Cleanly-quot-Starting-Over-quot-with-...
It starts with a process for cleanly starting over, and there is some discussion, and there is also a post (15) with links to older Desktop Software versions, if those are needed. Note that this is not, by any means, guaranteed to work...but it has worked for many to resolve issues they are having.
Also, for XP users, please be sure you are on SP3...that is the current minimum level required with the latest Desktop Software.
Good luck!

Help! Audio for 16mm project, material to FCP and back again to 16mm

I am getting ready to send an AIFF file of the audio I created on FCP, working with video that was created from a 16mm to video transfer at my lab. They tell me the transfer was a non-drop frame transfer. The lab made a digital file from the transfer, which I imported into a FCP project with 23.98 sequence settings.
I want to compare the frame length of my WP to that of my video file so that I can determine how the audio house who will be transferring the AIFF to mag needs to compensate, and I am confused about how to measure the video file's frame length. If the sequence settings are at 23.98 fps, and the project runs from 1:00:05;12 to 1:11:49;08, to determine the frame length should I be assuming there are 24 frames per second or 30?
I don't have access anymore to the FCP so I can't check but a basic question is: if the sequence setting are set to 23.98fps, does that mean the timeline only has 24fps? When I convert at 30fps, my video file is 22 frames longer than my WP...
Thanks for any advice and questions--that all may be explained poorly...

When your project and sequence settings are at 23.98, it is for two main reasons. 1. ou are working with video footage shot at 23.98 and 2. you are working with film (24 fps), which was ultimately telecined to video which runs at 23.98. This is mainly implimented because you plan on either going back to a higher resolution "online" which you will be synching up the timecode with a better quality copy of the tape at a coloring house, or you will be using the edl from the 23.98 sequence to give to a negative cutter, so they can cut the negative correctly according to the timecode and how it links with the keycode.
I assume you are making a final product that will be on celuloid- an actual film print, not a video copy. is this correct?
Please clarify the following: did you shoot on film, get a telecine to a beta or dvcam, do you have a timecode burn-in on the tape and when you captured the clips into final cut, did you utilize Cinema Tools?
If you did run your clips through cinema tools, did you do it correctly (starting the process on the "aa" frame).
Is your project set to 23.98 or just your sequence? when you place captured clips onto the timeline do they have to be rendered? Is this a sync project or was it shot MOS?
And lastly, as I previously asked, are you sending all of your negative, the edl from FCP and the aiff to a negative cutter?

Difference between signal strength and signal qual...

Does anyone know the difference between the two scores and what they measure - and why the levels change intermittantly. It's really affecting the quality of my tv picture.

The signal quality is actually a measure of the errors detected by the Vision box. Technically, the CBER in the advanced view is the "Corrected Bit Error Rate" measured as the number of bit errors per billion bits received (i.e. units are 1 x 10^-9). If you had 100 bad bits in a billion bits it would display 100, but would correspond to 0.00001% error rate.
Note this is AFTER the Vision box has done its error correction. The raw Bit Error Rate is typically much higher but the broadcast signal includes information to enable the receiver to correct for most errors.
If the signal level is very high it can overload the box and result in poor quality and poor picture despite having a high signal level.
As Umpire said a signal quality of 100% will result in a perfect picture.
Do make sure that your HDMI cables are away from your aerial cables as they can cause interference. If you use the TV's Freeview tuner does that give a better picture or does it also suffer in the same way?
Also try entering your postcode into the UK Free site at http://www.ukfree.tv/transmitters.php - this gives you information about your local transmitter, including distance, scheduled engineering work and aerial recommendations.

How can I set up my time capsule as the primary base station with a centurylink router? I'm trying to extend my coverage, increase signal strength, and be able to connect a printer.

I recently moved and now I'm trying to set up my Time Capsule as the primary base station or router with an existing network that has a Centurylink modem/router. The TC still has the settings for my old network. I also have backups on it. I have the data backed up to another HD so it's not an issue to return it to factory settings if doing so deletes the back ups. Do I need to restore it to the factory settings to set it up? Also, what settings would I select on the TC (and the Centurylink modem/router) in order for the TC to serve as the router, instead of the Centurylink router? I want to be able to use the TC to back up my Mac's, print wirelessly, and improve overall performance. I tried setting the TC up and ended with 2 different networks. Can anyone please help me with this?

The TC has to plug into the existing modem router by ethernet.. you cannot use wireless.
You have a choice of which is router.. only if Centurylink agree to bridge their modem router.. this has to be done by the ISP and often they do not allow it.
Is your broadband cable or adsl or fibre or ???
If it is cable and you are allowed to purchase your own cable modem pick a pure modem version with no router in it.. plug the TC into it by ethernet.
Setup the TC in DHCP and NAT mode.. (depending on broadband type).
You must reset the TC to factory to do the setup.. no files are lost at all.
Here is my current recommended setup.. with Yosemite life has become harder than ever.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
ie Start from a factory reset. No files are lost on the hard disk doing this.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 and TCwifi for basestation and wireless respectively.
Even better if the issue is more wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking. If the TC is main router it will not be an issue.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the laptop itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.
Macbook can't find Time Capsule anymore
Start from the bottom and work up.. I have a list of good network practice changes but I have avoided Yosemites bug heaven.
This user has had success and a few others as well.

My iPhone 4S stopped displaying the "Verizon" Logo at the top left of the screen. Now all it shows is the signal strength and 3G. It seems to be falling off the 3G network more than ever, What is going on?

My phone quit displaying the Verizon logo at the top and now it only displays 3G and the signal bar. And its falling off the 3g network after finishing with voice calls.

There is no roaming agreement with AT&T since a CDMA phone can't roam on AT&T's GSM network and vice-vera. The roaming agreement is with Alltel, which is in effect with Verizon since it was Verizon that purchased Alltel's CDMA network.
Edit, I guess it is with AT&T since I now recall AT&T purchased some of Alltel's assets.

Does turning off 3G really help call reception/signal strength ?

After experiencing more of the S.O.S. with the 2.1 upgrade I turned 3G off today.
It's really ******* me off that I am paying another $15 - $20 a month for something that seems useless and problematic (And now just to turn it off).
Does this really help with the issue pertaining to dropped calls ?

Hi guys
Hope you don't mind me dropping in, but I work in the telco industry, albeit in Australia. The turning off of 3G for better reception isn't an iPhone fault, it's a network thing.
Any phone with 3G capability is programmed to try and access the 3G side of the network first. It will continue to scan the network all day and night, anytime your phone is on to maintain signal. If it's unable to maintain service coverage with 3G, it then drops down to 2.5G, then 2G, then EDGE (if available in your area). If you turn 3G access off, it skips that step. The older networks are more reliable, but slower. They are also (now) much less crowded with users so there is less congestion and you get (on occasions) better signal.
The recent 2.1 upgrade would have modified the supply of power from the chipsets to the antenna's which is why many people are experiencing better signal strength and less dropouts, but it will always come back to the 3G coverage in your area.
I know this doesn't really improve things for you, but gives you some background to how the whole circus works.

Signal strength finder via black bt vision box

I have recently changed from sky (could be a big mistake) and have had constant troubles ever since.
The latest is I am getting pixelation on all tv channels.
Looking at the online "help" I have checked the aerial connections (all good), Aerial (brand new £50) and pointed in the correct direction. The next item was to use the handy signal strength checker as per BT's instructions.
However these do not appear to match what appears on screen.
You can check your Freeview signal using your Vision+ box, but please be aware that checking your signal will interrupt any recordings that are in progress. You only need to check the signal of one channel in a multiplex to know what signal you'll be getting for the whole multiplex.
How to check your signal:
Press the BT Vision button on your remote control.
DID THIS
Scroll across to Settings.
SCROLL ACROSS GOES TO TV SO I SCROLLED DOWN.
NO "SETTINGS" PAGE SO WENT TO "HELP & SETTINGS"
Select TV Settings.
DID THIS
Select the DTT Signal Strength page.
NO "DTT SIGNAL STRENGTH" PAGE THE ONLY OPTIONS ARE 1/sCAN FOR CHANNELS, 2/ CHANNEL MANAGEMENT, 3/ TV SHAPE.
The minimum signal strength and quality you need for a good picture is:
Signal Strength - 55%
Signal Quality -70%
Am I going mad ?
Can anyone help please?
Solved!
Go to Solution.

There is good news and bad news. The good news is that you are not going mad. The bad news is that you have a new version of the software which unfortunately doesn't include a signal strength tool.
Does your TV have a Freeview tuner? If so, try using signal strength on that.
Your signal could be too weak or too strong. If it's too weak you may be able to use a booster. If it's too strong you can use an attenuator.

Printer Signal Strength

My HP Photosmart C4380 All in One diagnostic summary shows a very low signal strength and will not wirelessly connect to the hub. How can I strengthen the signal? The printer wirelessly transmitted OK before BT corrected a problem I had between the hub and the emails.
Boyroy

If your router was replaced, even if it has the same network name (SSID) and password, the printer may not automatically connect. Here is how to re-establish the connection:
1. Press the Wireless button on the front of the HP All-in-One.
2. Press the button next to theicon on the display until Restore Network Defaults is highlighted, and then press the button next to OK.
3. Confirm that you want to restore the network defaults.
Next, insert your printer's CD (if it supports your operating system) to re-add your printer to your network. You will have to temporarily connect a USB cable to your printer, but wait until the software asks for it.
Can you get to the settings of the router?

Won't connect to wireless network but indicates full signal strength

I just bought a new macbook pro last week and connected to my home's wireless internet immediately with no problems. Until this morning it was working fine. When i opened my computer and it woke from sleep it would no longer provide me with internet access. Both skype and safari won't work but my icon indicates that i have full signal strength and that i am in fact connected to my home network. I ran a diagnostic test and the result was that it "appeared to be connected" yet i still am not able to access the internet. When i plug an ethernet cable into my mac the internet works and all the other computers in the house (all non-macs) have wireless internet access.
Thanks for any help!

When i opened my computer and *it woke from sleep* it would no longer provide me with internet access.
Sometimes a restart will correct network problems since you are getting the full bars and the diagnostic test confirms +"appeared to be connected".+

E4200V2 - Terrible Signal Strength

Upgraded from wrt610n to E4200v2. Nice router like Cisco connect but router has terrible signal strength and no longer can connects dma2100 media extender. Driving me crazy

You can try the following combination of settings:-
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
          1] Open the software and go to the option which says "Router Settings"
          2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
         3] Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your router's main/ basic setup page)
         4] Then click on Security tab disable SPI Firewall Protection, uncheck Filter Anonymous Internet Requests...
         5] Then click on the Administration tab and disable the UPnP feature...
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the user name field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.
Second, try to upgrade the drivers for the WLAN card of the wireless computers.
Third, try to change the different channel to which ever wireless frequency you are trying to connect. Here is the link: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=c57ac037be4b4e10b8a24379d4089aff_15658.xml&pid=80&...

Slow signal strength fluctuation and up/down client link

I have completed installation and configuration system which consist WLC5508(HA),MSE and WCS (all soft are last version). APs - 1252 a/b/g/n. But have problem, some clients have a slow signal strength fluctuation and up/down client link per 1hour or 30minuts. I see that this occur, when client change AP, but I can't understand why because client are not roam, they on the one point during all time (laptop on the table for test).

Signal strength measurement is not an industry standard measurement, although dB and mw conversions are a defined standard in the aspect that 100mw is always 20dB not every client card software defines an RSSI of -67dB to be excellent.
So the validation of signal strength can vary widely in the client card software between brands and even between models, or between software releases. So there are a number of factors that play into this also keep in mind that each client cards driver software has it's own roaming behavior, that varies as widely as its depiction of the signal strength values.
Additionaly power save functions and the antenna type in the device can all affect the perceived signal strength and roaming behavior.
So the flux your seeing could be a result of the any of the following items or something else
network design: meaning possibly there is insufficent coverage and the flux you are seeing is actually multipath.
Client Card: Some client cards just don't perform well and have sub-standard components that impact performance
Driver Software: some driver software is just bad, it has poor algorithims, poor logic, etc.
Bad antenna: the antenna in the device could be of poor quality or defective.
Hope this helps...

Why do I have such poor/sporatic signal strength?

I have an iBook G4, and ever since I bought it i have had trouble with wireless connections. In my home, a small one bedroom apartment, I have and airport station. Connected to this is an external antenne. This is hooked up to a PC. My laptop has an airport extreme card. I have double checked and the card as well as the airport base station are installed correctly.
I am able to connect to the internet in my apartment. However, my wireless signal is always very weak. I am currently less than ten feet away from the base station and I am at less than half signal strength. Inside of my bedroom, approximatly twenty feet away from the base station I have little or no signal strength depending on what part of the room I am in. The signal strength varies constantly and does not allow me to connect to the internet.
My boyfriend has a PC laptop and is able to connect fine anywhere in the apartment. Also, he is able to detect several other wireless networks, where as I am only able to detect one.
When I am outside of my home and attempt to use hotspots, at school or coffee shops, I have little or no signal strength and am almost never able to connect to the internet for more than five minutes at a time, if at all.... All around me I always see PC users, as well as other Mac users serfing the internet without trouble.
How can I fix this? Should I buy a replacement airport extreme card? Is there any external USB devices that would help?
Thank you in advance for any help you are able to provide. I am desperate and will take any suggestions.

Hi Kat,
Welcome to the Discussions.
An improperly inserted antenna is the usual cause of weak signals. It takes considerable force to get it all the way in. This article illustrates a properly attached antenna.
