    i have the NFC enable moto flip headset, and it seems to go maybe 100 feet tops from my GN before it drops the connection. no big deal, the only time i'm that far from my phone is when i was testing it lol

    Do you mean a bluetooth head set?

    OP has got to be talking about bluetooth there's a reason it's called Near Field Communictions. Because it doesn't work from Far. ;-)

    Actually, I'm not sure what he's talking about.


    NFC = less than a foot

    BlueTooth:

    • Class 1: range up to 100 meters (in most cases 20-30 meters)
    • Class 2: range up to 30 meters (in most cases 5-10 meters)
    note: I think things like mice/headphones/handsfree are all class 2


    Wifi : 150-600 ft (approx. depending on interference, walls, etc)

    I thought BT accessories were only supposed to be good for 10 Meters (~33 feet)? Seems to be accurate realistically too.

    ok lol

    to clarify, i'm referring to the motorola elite flip bluetooth headset, which has NFC tech and an advertised range of 300ft with a NFC enable phone (like the GN)

    Most Bluetooth devices are Class 2 (see specs above) even if the Moto you listed is Class 1 it still would need to connect to another class 1 device to reach 300ft.

    right, but the moto elite flip packaging says "300ft range", obviously when used with a NFC enabled phone like th eGN.

    now, yesterday, i did walk about a 100ft away from the phone and didn't loose connection....

    When long ranges are given like that, it is virtually always in "ideal circumstances" - as in, direct line of sight, no walls.

    The range has absolutely nothing to do with NFC. None. Doesn't matter if it's used with a NFC enabled phone or not, range will be the same.

    It only uses NFC to pair the headset to the phone. After that, it's all bluetooth. And I'm sure 300ft is being generous.

    Right. NFC range spec is in the range of centimeters (single digits, too).

    As fr as 300 ft, we all know that there is an implied "on a flat plane with no obstacles and no ambient humidity and the correct placement of Jupiter in the sky" that goes along with those specs. :rolleyes: :p

    then why does my moto elite flip headset advertise a 300ft range when paired with a NFC capable device? :thinking:

    Im not buying that samsung and moto are setting themselved up for a false advertising suit.

    It may not get 300ft unless on a clear day straight line of site, but i have gotten 100feet out ofit so far, which is already much further than the standard bt headsets range if 30ft.

    Sorry, but it doesn't matter if you're "not buying it."

    NFC's only purpose in life is to communicate with things 1-2 cm away.

    It does absolutely nothing to improve the distance over which Bluetooth can transmit.

    Also, it's not false advertising to say it can transmit a certain distance when paired with an NFC device, just because it can ALSO transmit that certain distance when paired with a non-NFC device...

    If NFC works more than a few centimeters away then it can't meet its intended purpose. NFC is intended for intentional near field communications. In other words, two devices are supposed to be purposely put very close to each other to exchange information. This exchange is supposed to happen by doing nothing more than bringing the two devices close to each other.

    Bluetooth pairing can be accomplished this way-- but the actual bluetooth communication is completely separate. If it worked at distances further than a couple of inches it would not be useful for sharing information. You wouldn't want someone to be able to get your credit card info from further than a few inches and NFC can be used for payment. If anyone could connect to my device- even if it then asked me to allow it do something- just because NFC was on, it would be a HUGE security risk as bad or worse than allowing bluetooth to be discoverable all of the time.

    All that said-- I cant wait until you see signs with NFC built in-- touch your phone to the sign and it gives you phone contact to a business or a coupon-- or maybe programs a reminder to watch a TV show or to check out a new restaurant. Cool technology for sure!

    You should trouble yourself to read my post fully this time-and read the one just above as well.

    Please stop trying to argue a topic you are clueless on. ;)

    I'm not sure what you consider false advertising? The device has 2 features:

    1) uses NFC for pairing, so you don't have to bother going into the BT menu to pair

    2) Up to 300ft distances- "up to" being the key phrase, not guaranteed all the time

    Note that 1) is not related to 2)

    What about those things do you consider false?

    You know...nothing he said was incorrect. And rereading your post does not correct that. Regardless of what your post says (which is basically that you are not buying that the only reason for this claim is advertising and that the range is good even if not 300ft), NFC does NOT communicate more than a few cm. A whole inch is pushing it.

    if I am missing something, do tell me. But I doubt I am. People are offering explanations and you seem to be berating them for arguing a topic they are clueless on. Might I posit that it is you who is clueless?*

    -Nkk

    *This is not a bad thing (nor is it really an insult). Everyone is clueless about some things--especially me. Most people just choose to accept knowledge with a thank you, not an unfounded argument.

    EDIT: Also, why is there a frowning sad android icon atop my post, and where did it come from?

    Fine. Educate me.

    You have said repeatedly that you believe there is some correlation between NFC and the supposed extended range (300 ft.) of the headset.

    I am saying that there is no correlation, period.

    So please, if I am so clueless (given that I know how both underlying technologies work), tell me what I am missing.

    So, an interesting note.

    I was told this:

    And then in another thread I see this, on the subject of where Google Wallet can be used:

    Why am I the one who is called clueless on how this technology works?
