    Question Location Estimation based on Multiple BTS Cell IDs

    Hi,
    I want to write a program to estimate phone location depend on cell ids and signal strength on s60. i need at least 3 BTS cell ids and their signal strengths at the same time to estimate at a reasonable accuracy, but i can retrieve only one cell id at a time, the most powerful signal. I know that the phone itself knows about every visible cell, so is there any way to discover these information?
    AFAIK, there's no public API or AT command for this, maybe it's against law !?
    Any help would regards.

    There is no public API, anyway, you could always try API-Partnering, will cost you some money and restrict you in some ways propably, also no quarantee that it is possible, but if you really need an answer, you could always try that way.

    It's partially possible.
    Phone can only get the Cell ID of that cell it's registered to.Getting IDs of other near cells isn't possible.

    As an alternative way, you could use channel numbers (instead the Cell IDs), once they are pretty retrieveable from near cells.But for that (and for signal strength too), you'd have to go through partnering, as Jukka's already explained in previous post.

    Hi hU,

    I have same problem with you,
    did you already succeed to retrieve the neighbor cell ids?
    would you mind to share that info with me such as article, source code or any reference?

    Thank you in advance for your kindness, please help me
