Set clock from Cellular network clock - General Topics

I need to find a way to set the time of a Window Mobile 5 unit (JAMin in this case) from the signal from a cellular system?
I know there are atomic clock sync utilities but those will not do for me :-( I would like the time to change to the current local time as I land in different airports, just like regular cell phones on the market.
I am even willing to purchase software to do this if needed, but after hours searching, I have come up with nothing that syncs from a cell signal.
Any ideas, links, hints, tips, tricks or _____ is much appreciated.
Thanks

Dear CrozB,
It is possible to set the clock of your cell with the network time. However, for that you network operator has broadcast the network time. Therefore, you can ask the technical helpline of your operator to check if 'Time Broadcast' is enabled on the BCCH.
Cheers,

[App Idea] GSM/WCDMA Switcher

Hey guys,
As the radio stack is the second cause of battery draining after the display, I was thinking about a way to save battery life by reducing the impact of the 3G connection. Most of the energy saving apps on the market are only disconnecting the phone from the APN, but this isn't a great solution as each app could be set to update at different times and thus being unable to download data even if the user sets some exceptions. So I thought that an application which operates in the following way could be great to save power:
- The phone uses the 3G network while the screen is on;
- It switches to 2G when phone is in standby mode;
- It disconnects the APN data connection while the phone is using a WiFi Network;
Obviously to avoid possible issues during the switch between 2G and 3G the following rules are applied:
- If there's an incoming call or a phone call is being performed, there won't be any radio switch until the phone call is ended;
- If there's an incoming SMS/MMS, there won't be any radio switch until the text message is fully received.
Unfortunately as I'm not a Java developer I can't code anything like this. But let me know what you guys think about my idea and if it's technically feasible... Maybe some developer could be interested into further exploring my thoughts and will try to create such an app
Cheers
I'm not a developer but I think it sounds like a great idea. I go into settings and switch it to 2g when I'm in spotty areas outside of town. I have to work a bit to keep my N1 battery alive all day...
Hello I'm new here.
I don't know if your suggested profiles are the best case scenarios. You would need to calculate your data throughput, not just the radio power.
If you need to send 100 packets, your radio would be on the longest for edge > 3g > wifi. So, even though wifi uses the most power, it would be for a much shorter duration.
A profile for "place calls only" would work somewhat like airplane mode, but still keep track of towers. Your phone just wouldn't register on the network unless you wanted to place a call. You would miss your incoming calls, have no data connection, or sms. But, you could have it check at an interval for voicemail or sms. This would be most useful for "ringer off" situations like class or meeting.
Afaik Android is always connected to the APN even if the phone is not downloading anything, consuming a lot of battery power. On other platforms, i.e. Windows Mobile, the connection can be terminated by user and re-established when an app needs that.
The amount of data downloaded by widgets, Google mobile applications or apps which operates in background like eBuddy or Facebook should be quite low, so downloading the required data by using GSM or WCDMA while the phone is in standby would be pretty much the same. The only difference is that downloading stuff using GSM/EDGE should take much less energy power.
So that's why I thought about the app I described before: the phone can save a lot of energy power while in standby and be back to its full horsepower when there is any kind of user intervention. Pretty much the same thing that the system already does for CPU usage. It scales to the less consuming protocol (or, in the case of CPU, frequency and voltage) to save power
I know on the google api it isn't possible to do this, but I don't think that isn't the problem.
At the moment you have 3 options. GSM only, WCDMA only and GSM/WCDMA. Whenever you switch between the 3 of them, the phone will lose signal for 10 seconds before it can find the best network. So the switcher here is not the best as you will lose connection, and what if you are downloading something at the same time...
What you need is when the phone is on GSM/WCDMA that it knows the best network to pick from depending on the phones lifecycle. GSM/WCDMA loses battery power because it always tries to find the best network to connect to, so for example if you are on GSM it will constantly try to find a 3G network etc (as far as I understand it).
What we need is the ability for the phone to stay on GSM when the phone is idle and then when the phone is woken up to automatically start to search for a WCDMA network and then gracefully switch over like it does now. For this I have no idea if it is possible as I don't know how the scanning of the network works. If it is possible then that would be wicked. But this is what we need.
my preference would be if the phone would stay on 3g as long as any possible even if there would be a more reliable 2g connection and only switch to 2g if there really is no way to connect to 3g. turn of apn if the screen us turned of for longer then 1 or 2 minutes and only check every 15 minutes or so.
most of the time I'm on 3g only mode . since I live in a city I got good coverage almost all over the city. only problem is that when there is no 3g available also my phone is unreachable. I don't really miss data connectivity when there is no 3g since 2g is so slow that I rather have no internet at all but not being sale to be called or texted is a major disadvantage...

[Q] Questions about hidden settings in Android 2.3

I have quite a few questions some hidden settings I found while using ANYcut app.
My phone is the Epic 4G and on Gingerbread leak EH17 if that matters.
1) MSL code. I did some google searches and found that is an algorithm to determine the ESP and other things. What is the algorithm? If a phone had a bad ESP could you change the MSL to make Sprint think there is a clean ESP?
2) Cell broadcast SMS. What is this? And what is it for? some of the settings are Emergency broadcast, administrative, maintenance, local weather, area traffic reports
general news:
local
regional
national
international
And those same options for other types of news also
3) Data Create. I think this one is self explanatory. But is this for the maximum number of each I can store on the phone before it deletes them. So if i set the maximum number of texts in my inbox to 500, that is the maximum I can store?
4) Dial up networking. I thought this was going to be the 3G but I was wrong. What is it? I turn it on and click on the connection settings but nothing happens why?
5) Dock settings. Its obvious. But I herd that you can connect your phone to the a computer via USB and have it act as a dock and play songs or videos through the speakers on your computer. Is this true?
6) DUN. It has a picture of a computer with 2 green arrows. And 2 progress like bars, labeled, RX and TX. Any ideas? I was thinking it might have to do with USB activity.
7) EVDO settings??? I am on the Sprint network. Why would they not opt this options out of there SDKs? Isnt EVDO T-Mobile network? But I am on a leaked build so maybe they haven't removed it yet?
8) Preconfig? I really not sure what this is. It says sales code and then an input field. And at the bottom a button that says install and one for cancel. What would this be for?
9) License settings. most of the options are obvious but there is one for expiry reminder. whats that? reminds you when your DRM content is going to expire?
10) MMS Provision Settings. some settings are transaction logs, optional field attendance, UA string, UAP url, and test modes. Anyone know what this is for?
11) Now one that is just called advanced. Some options are home orig. vocoder. homepage vocoder, roam orig. vocoder. whats this for?
12) USB Logging(DM) One section is Function, with the options of, enable and disable. And other section called Type. the options are CP only, AP only, CP+AP. No idea about this one
13) WiMAX CT. there is a button at the top that says open device. then options of max num of used FA, FA Index, BW, FA index. Are these settings for WiMAX networking?
14) WiMAX Mode Change. The options are, SDIO, WTM, DM, USB, Auth modes. What are these different modes and what do they do?
15) WiMAX LineTest. Optioins are, write eeprom, power on, power off, write mac with and input field, and read mac. any ideas??
16) Work mode. it says Work Mode :2 and then a button that says set work mode. and i can set it to 1, 2 or 3. what are these different modes for?
Bump - Anybody want to jump in and help the op?
Wow, with all the brilliant minds on here no takers? Or is the question too big for anyone to take a stab at?
First off, as someone who somehow burnt out my 4G chip, I would suggest that anyone reading this be very careful, search here and google before fiddling with settings. lol
Since I am doing research to see if I can get my Wimax to work better I will answer a couple of questions a day, however anyone feel free to jump in.
1) MSL code. I did some google searches and found that is an algorithm to determine the ESP and other things. What is the algorithm? If a phone had a bad ESP could you change the MSL to make Sprint think there is a clean ESP?
The MSL code or (Master Subsidy Lock) is how a phone carrier keeps the phone from going to another network, however some phones including the E4GT can be found through using Android Debug Bridge (adb) a command line tool that lets you communicate with an emulator instance or connected Android-powered device - or even easier just go to the market and download, for free, Get My MSL which will display your Master Subsidy Lock code.
2) Cell broadcast SMS. What is this? And what is it for? some of the settings are Emergency broadcast, administrative, maintenance, local weather, area traffic reports general news:localregionalnationalinternationalAnd those same options for other types of news also
According to Wikipedia:
Quote:
Cell Broadcast is not as affected by traffic load; therefore, it may be usable during a disaster when load spikes tend to crash networks, as the 7 July 2005 London bombings showed. Another example was during the Tsunami catastrophe in Asia. Dialog GSM, an operator in Sri Lanka was able to provide ongoing emergency information to its subscribers, to warn of incoming waves, to give news updates, to direct people to supply and distribution centres, and even to arrange donation collections using Celltick's Cell Broadcast Center, based on Cell Broadcast Technology.
All for today. Peace

[Q] Automatically switching network provider based on location

Hi, I've tried to do a bit of searching on XDA / google but not found exactly what I am looking for. I've seen all the APN switchers but these do not alter the actual network provider from what I understand.
What I would like to do is have an automated why of switching between T-Mobile and Orange networks. In the UK we can now use either network but the current policy is that when the provider is set to automatic network selection if a T-Mobile signal cannot be found then it should switch to an Orange signal if one is available.
This is fine but my T-Mobile signal is not very good in certain locations (fail to get SMS message) and so I'd like to be able to switch to Orange without going through the system settings menu which is slow because of the network search.
I'd love to get a tasker plugin or script that could automatically perform the switch based on location if possible.
Any info would be greatly appreciated.
Thanks
Hi
Did you find any solutions for that because I need exactly the same thing?
Thanks
Sadly not, I've ended up just using the Orange signal full time.

[Q][App Request] cell network ownage info

Hope someone can help with this request/question
I'm currently on a PAYG network in the UK (ASDA) but this company is a 'virtual' network using one of the bigger network companies (currently they are using the Vodaphone network)..quite soon they are moving to EE (Orange/T-Mobile) network which would NORMALLY not be a problem except.....
I work in a factory & mobile signals in plant is rather 'sketchy' the best of times... the Vodaphone network seems to have the best signal there & this is why I chose a provider that uses this network. When they (ASDA) move to EE I'm worried that I will start losing signal strength etc & so I'll may be forced to find another provider
Now onto my question/request..
I was thinking that IF I could scan the area I work (i.e the factory) & find what cell towers are around, & what strength they are THEN find out WHO those cells belong to (as in - whether it's O2/EE/Vodaphone that owns them) I should have a good idea If the EE network will still work in plant & I won't have to start looking for another provider..
...If they aren't any good - I could find out which company DOES have the best signal in plant & then have to move to that provider instead
I know I could just use my phones 'network scan' to see who's 'around' but this doesn't show how strong their signal is
I could also go out & get a free PAYG sim from each company & put it in my phone & see which give the best reception
and I know there are apps that will show 'Cell Info' (some show quite detailed info that completely 'gobble-gook' to me ) but none that I've found tells me WHO the cell belongs to
So - Is there such an App (preferably free) that anyone can suggest that will allow me to.....
> Scan the available cells in my area
> Find out their signal strength
> and MOST IMPORTANTLY which network company (O2/Vodaphone/EE etc) OWNS that cell
It also has to be 'simple' to understand.. all I want is an app that shows how many cells in the area, how strong the signal is for each cell & a name of the company that the cell belongs to
Many thanks in advance

Comunicate without standard network.

13I find myself with a few phones handed down to me, and I am often in areas where there in no mobile phone network available,
I am curious as to weather or not these Android phones (on which I have gained root access) could be perhaps booted to a system that allows communication directly between the phones instead of via the non available mobile network.
If I remember correctly, an article I read some years ago described an open source project designed to offer telecommunications using the transceiver in each phone to create a network for areas that had no other available network.
If anyone could point me to some information on the above described network, or just using these as "walkie talkies" I would very much appreciate it.
I was not able to find much in the way of relevant information, but Wikipedia says,
Developments
Some cellular telephone networks offer a push-to-talk handset that allows walkie-talkie-like operation over the cellular network, without dialing a call each time. However, the cellphone provider must be accessible.
Motorola has IDEN cellphones (e.g., i867) that can have 15 conversations over each of 10 900Mhz channels (see Moto Talk) between compatible cellphones without using the cellphone network or a base station. This is very useful outside the range of a cellphone provider as well as reducing network charges.

Smartphone apps
A variety of mobile apps exist that mimic a walkie-talkie style interaction. They are marketed as low-latency, asynchronous communication. The advantages touted over two-way voice calls include: the asynchronous nature not requiring full user interaction (like SMS) and it is voice over IP (VOIP) so it does not use minutes on a cellular plan. Applications on the market that offer this walkie-talkie style interaction for audio include Voxer, Zello, and HeyTell, among others.[7] An application that offers this style of interaction for video is Glide.[8]

Nothing in this seems to be what I am looking for.
have you tried restarting your phone? my phone sometimes crashes and restarting works perfectly, try it seriously
There may be apps that provide Walkie Talkie like functionality over Wifi, but I think you need to distinguish what you are doing over wifi, bluetooth, and cellular. I'd go with one of these. You might even be able to setup some kind of mesh-based network using wifi - depending on the area you are trying to cover.
iDen and other carrier based PTT solutions are based on connectivity to cellular networks, and won't help you here. Additionally, most GSM networks are not outfitted with native PTT functionality. You are best working with Local Area Networks (LANs, like WiFi) or Personal Area Networks (PAN, like bluetooth)
WiFi and Bluetooth operate on spectrum which is unlicensed and available for public use - with some restrictions, such as power output and the like. Anything you could coax out of WiFi or Bluetooth should be fine.
Cellular, on the other hand, is an entirely different breed. Cell networks are generally regulated and licensed by relevant government authorities. Trying to setup your own cell towers is likely illegal in most countries without licensing or regulatory approval - with a few exceptions, like carrier sponsored micro cells. That would include tampering with the cellular radios in most devices.

Yes,,, the legal issue is something I had not yet considered and you make some important points.
It is likely that even if I find the information on the project I mention above I will not be able to do anything other than learn a little from it, that's OK.
You mention IDEN as being carrier based, as far as I can tell IDEN is one of the few that is not.
From my previous quote

There is more info on this at this site .wikipedia.org/wiki/MOTO_Talk ( need to make more posts before I can give a link ).
I do however note that some carriers do not allow this feature to be used, or limit its use.
MOTO Talk also works only on some specific Motorola phones, reading between the lines there seems to be some hardware as well as software that is unique to these models.
I'm most interested in the open source project ( I think it was open source ) that I read about some years ago, perhaps it is on SourceForge?
I have trouble finding a useful search string for Google, any suggestions?
