for better positioning I want to use Timing Advance with Cell ID.
Well I just begin finding some docs about software implement on Windows Mobile OS, so know just a few about theory now. I didn't find any program to do so.
Is there someone already did this? or know about this topic??
Thansks a lot. :idea:
I dont think this is possible device side..
Mobile network operator has this kind of information, so unless you can plug into their GMLC your out of luck.
thanks Hickhack
I will continue search for information...
If you come across anything please let us know...
what exactly is timing advance?
Timing advance
From Wikipedia, the free encyclopedia.
In the GSM standard, timing advance corresponds to the number of milliseconds the signal from the mobile phone travels to the base station. GSM uses the TDMA technology for sharing one frequency between several users, assigning timeslots to the individual users sharing a frequency; each user can transmit only in a certain time. But the users are in different distances from the base station, and the speed of light is quite slow, so the precise time the phone is allowed to transmit (timeslot) has to be adjusted accordingly. Timing Advance is the variable controlling this adjustment.
Timing Advance is significant for privacy and communications security, as its combination with other variables can allow locating the mobile phone user.

TA - Timing Advance
In order to get TDMA (Time Division Multiple Access) schemes to work, the time-frames from each mobile must be synchronized when received by a base station. This synchronization is achieved by using the concept of TA (Timing Advance). The degree of synchronization is measured by the base station on the uplink, by checking the position of the TSC (Training Sequence Code). This training sequence is mandatory in all frames transmitted from the mobile. From these measurements, the base station can calculate the TA and send this information to the mobile.

I found that Nokia handy hat a NetMonitor, which can display Timing Advance parameter.
Like this software on Nobbi.com website:

Hi everybody, been surfing the forum now as ive got an MDA Vario, unlocked it etc etc using the threads on board.
I've been trying to get my pc wi fi router to work with my phone, but have had no luck as of yet; however last night i came accross a broadband router which i thought was mine, i only used the connection to try pocket msn and look at googles layout on the phone. After a while i noticed i was not getting a 2mb speed and the signal strength was weak, therefore i noticed im using someone elses broadband.
My question is..
is it possible for the person to see my contact details on my pda .e.g my house address, and my home telephone number which is stored on the pda?
no phone has no network shares,
chances are they are ur next door nieghbour anyway lol
so they know where u live
:? so they wouldnt know any of my details?
well i only picked up a very weak signal
I think that the device does identify you with the first name and last name of whatever is set in the "Owner Information" properties. Can someone confirm? Is there a way to change that?
I would assume that rather than owner details, the PDA's "friendly name" would be used.
All moot as regardless of my best efforts I cannot get the thing to even ping, never mind show up on any networking kit I have. As someone has said they have no shares.
I am pretty paranoid about WLAN stuff as I run several and know how easily most are hacked - however, I am not in any form of panic re my Wizard.
It seems to me that PPC's are designed as a client side only system, which does seem sensible coming to think about it.
the only thing that they could trace is any logs on the router, with your IP and MAC address... i would not worry about it too much. the person is obviously stupid enough to NOT secure there network so i doubt they have the brains to trace you.
Thanks for the info guys
could be a honeynet.......
Odds are good that your neighbor can detect that you have been riding on his nickel. I am generalizing, but if they were bright enough to be watching their router logs and dhcp logs for rogue devices connecting then they would likely have also WEP'd their box.
I agree with VAP that the risk of the neighbor prying into your device over the 802.11 seems pretty small.
The "WM_Glenn" device is my TMO MDA

I've been fantasising about getting a Universal for sometime but I dont want to ditch my BA. As I don't see it as being that much of an upgrade to warrant paying & hassle of arguing with O2.
However, I'm on-call for my company and was wondering what the quality of VNC over 3G was like?
Has anyone tried this and is it practical?
.: bump :.
Not sure about over 3G but can imagine it's roughly comparable with normal VNC over broadband. Also depends what version of VNC you use on the exec as there are a couple.
Over wifi on the exec it's pretty good, though I've found that logmein.com is a far better solution - if such an option is open to you. Also found that dynamicdns.com is meant to be good, and allows you just to RDP onto installed terminals.
If none of these are applicable, then VNC on the Exec is just as good/poor as desktop equivalents.
Cheers

Thank gawd Citrix released the latest WM 5.0 compatable version of GoToMyPc Pocket View so now I can remote into my desktop using my handset. GoToMyPC PocketView allows pda owners with a gotomypc subscription to access amd work on any registered machine remotely.
If security is an issue it uses an SSL-encrypted Web site and end-to-end AES 128-bit encryption of the data stream and chat as well as keyboard and mouse input; multiple passwords, including an access code that resides on the host computer and is never transmitted or stored on GoToMyPC servers; and notification when the PC is accessed.
Because the o2 XDA Exec has a 640 x 480 touchscreen and UMTS (3G) capacity it makes life a whole load easier using PocketView than on previous pdas. UMTS has a theoretical speed of 384 kbs so any refresh delay is hardly noticible especially combined with the fact that the software itself pixel refreshes.
Here's a couple of images of it in action!

They seem like the perfect combination for those who intensively work remotely who insist on not having to drag a laptop around with them.
Thats settled then - I'm getting one.
Also what mount are you using in the car?
Brodit Active!
www.dsldevelopments.com are a good supplier (I know the owner and bought the Exec cradle from him)

sweeeeeeeeeeeeeet! :lol: now that's a mobile office
I have some industry specific software designed for desktop/laptop use that would be great if i could use it on my dopod 838pro. It is unlikely that it would be released in a WM version but i were wondering if there is an emulator that i could use or any other way of making this work.
Thanks
The System Requiremens for this program are Windows 95 or higher,32MG Ram, 256 colour videocard (16 bit coloour or higher), 250mg HD free, 800 x 600 colour moniter

Not sure if it is still supported or being worked on, but look here for a way to do it.
You will also have to look here for some of the files that are mentioned.
The rest I shall leave as an exercise for the student...

Couldn't you run it under terminal services if it is an industrial strength app?

Thanks
Has anyone had any experiance with the bochs emulator (especially on the hermes) and can tell let me know of any draw backs of this
Terminal Services? i am a noob and if some could explain this to me or point me in the direction of information to help my understanding this would be greatly appreciated
Bochs is slow. ARM processors aren't super fast to begin with, and aren't great at certain types of math functions. As a result, Bochs is perhaps unusably slow. Certainly investigate it, Mamaich has done the best work on it. If you have the resources, have it optimised and report back.
However, if XP could run well on PocketPCs, Microsoft wouldn't have introduced UPMCs right?
So, the alternative to running an XP app directly on the PocketPC is to run it not on the PocketPC.
Terminal services is the Remote Desktop software built into most of our phones. It will let you log onto a "remote" PC's desktop and control it as if you were sitting in front of it. With a high speed data connection, it's very usable, and obviously you get full XP capability (or indeed if you use an alternative like VNC, you can have full Linux or OS X or anything capability) on your PDA.
However you will incur data charges for the connection. But if you're on an office connection or wifi, no problem.

This is a 1.0 release and is looking for people to try it out. The application allows for pinging a host, trace the path to a host, do Whois lookups on domain names, and even test ports. You can download it from http://www.securenetworksystems.com/SecurityTools/ and can get a demo license from http://www.securenetworksystems.com/SecurityTools/demo.aspx that will give you a week of testing the software. The image below shows a trace that is mapped out.
We are releasing this for testing before it goes up for sell, so any productive feedback is appreciated. Please note that full installation size is around 45MB (due to a database size), so it is a good idea to verify you have enough space on your phone/device or install to a storage card.

Latest Release (9/15/2009)
Enhanced: Finger control for the map (larger zoom buttons).
Fixed: Scaling issues for VGA/WVGA (large screens) in the port testing section and in the setup wizard.
Fixed: An error in setup wizard if Device is selected for tile cache location.
Fixed: If a service returned special characters (such as SSH) in port testing during a single port test, the entire message would not be displayed. The message is now shown without the characters that can’t be displayed.
I just added some additional picture so you can see some of the other cool functions of the application. The only thing that isn't shown here is the WHOIS lookup. Hope everyone is enjoying the free trial.
Nice tool to do simple troubleshooting while on the road.
The Whois gives a lot of garbage. It should search for the exact match. If people want more sites that aren't exact matches, wildcards should be used. Instead, a Whois for google.com gives no relevant data, and you have to do another search to get the info. The search gives things like google.com.zzzzz.download.movie.online.zml2.com, as well as addresses to porn sites.
Basically, I'd like to get the ball rolling with making a low cost (Free, Open Source would be best) IR Universal Remote application for the Android Platform.
I wrote up this wiki to help establish current info:
Slatedroid Wiki - Adding IR output to Android Devices
Please see the wiki for all the details, but essentially, the hardware involved is trivial. As far as coding, the following needs to be written or ported from other projects:
A GUI to manage the buttons and selection of devices
A parsing function to read info from pre-made remote control code text files
An audio signal/waveform generator
A database to store the information
All of this stuff has been done before, it's just a matter of bringing it all together into one android-based project.
If the project really took off, future development might include:
Support of LIRC, Pronto, CCF, and/or other IR remote file protocols
Integrated controlling of WiFi and Bluetooth devices
A pre-parsed central database stored "on the cloud" for all major devices
Possibly supporting the "learning" of a new device (would need a IR sensor/decoder attached to microphone input)
Feel free to discuss, correct any errors, bounce new ideas around, etc.
With google tv most of plumbing code and the UI will be available, albeit for a small set of machines and via bluetooth. (google remote)
They used to do this actually.
I remember a long time ago, it was with remote software. It would store the IR signals as WAV files recorded via a 3.5mm headphone IR sensor.
I think you could even make one. All you need to receive and send IR signals is a audio recorder/player. Map certain software buttons to each audio file to make a "Remote Controller" type of device".

Yes, all that info is already in the wiki. It's been done a million times, which makes me wonder why there is no one around with an android version yet.

Google TV will be WiFi controlled though, not IR, right? If the source code for the gui was available, that would be a good start.
