    Question Matching Data sets Based on Similar Entries

    For a school project I'm attempting to develop a crude system to for determining my location along a single axis (the street I live on) based on wireless networks. I've already collected a series of data points, at each point approximately evenly spaced out (based on house address) I logged every viable wi-fi network, my overall groal is to take a reading without an address, and then find which known entry it matches the most closely.

    I have unique identifiers for each network (MAC addresses), now I need some way to match the known and unknown data sets- the method of doing this I envision is to assign each known entry 1 point per matching MAC address, find the total number of points per entry and then say the location with the most matching MAC addresses is the correct location. Is there a reasonable way of doing this, or should I look into some alternate method?

    Thanks,
    Djbeadle

    Hi Djbeadle,

    Do you need formula in D4:D7 where you have put in question marks ?
    What result you are expecting, enter manually and I'll try to obtain that using formulas. thanks.

    For each Unique Network Identifier from the unknown section that matches with a Unique Network Identifier from the known section, I'd like to set column D equal to either 1 or 0.

    Thanks,
