not understanding hotspot and tethering

    My phone (galaxy s3) can get a signal from my supplier without me having to be hooked up to wi-fi

    Yesterday I enabled tethering and hotspot of my phone and turned off wifi

    I connected my phone via USB to my laptop expecting that my laptop would be able to go on the Internet via my phone but it couldn't.

    The laptop and the phone saw each other.

    After checking on the Internet it seems that my phone must be connected via wifi before I can use my laptop.

    But that doesn't make any sense to me because if there's a local hotspot then I can get my laptop on line without using my phone.

    I'm obviously missing something here and an explanation would be much appreciated.

    Sorry for such a newbie question but only got my first smart phone a couple of weeks ago.

    Your phone should be connected to the internet. Then what you do is simply turn on your tether (hotspot or wired), then connect your computer. If you choose mobile hotspot, your computer will see your phone as a WiFi hotspot. Just connect to it like you would connect to any normal WiFi hotspot.

    Thanks for the kind reply.

    Did what you suggested and got a message telling me that I need CDC drivers.

    After a little searching on the web I see that installing Kies might be the answer.

    Seems like downloading and elephant to kill a fly.

    And would W7 find the files automatically that are a part of Kies?

    Plug phone into charger, preferably somewhere with decent signal. Make sure it is receiving 3g. Switch on the hotspot app on your phone (you might need to configure it first by giving it a SSID name & password). Turn on wifi on computer, search for your hotspot name, connect by entering the password.

    You only need CDC drivers if you would be using USB tethering. If you would be using hotspot tethering, the phone won't even be connected to the PC in any physical way.

    Will try it in the morning. Getting late here in Israel.

    Orange Israel voice network uses GSM 900/1800 frequency and UMTS technology. Orange Israel 3G data network uses HSPDA technology and covers over 90% of the country. Most GSM 3G devices can be used on the network, among them iPhone, iPad, BlackBerry, Android smartphones, different cellular modems etc.

    So pretty sure that I have 3G but how can I be certain? Galaxy s3

    One of the reasons that I'm interested in this is that I may go to the Himalayas for 3 weeks in December.

    If you have internet on your phone, then you have internet to share. Can you access the internet on your phone without being connected to WiFi?

    Yes I have. Thanks

    Ok the laptop sees the hotspot and asks for a password.

    I've never assigned a password.

    So what next?

    Sorry you guys are having to spoon feed me with this.:eek:

    OK I did find the pre-assigned password and can log-on.

    But its very slow and I get an error message from IE (I normally use Firefox or Chrome but tried all of them) that the signal is very weak.

    Its slow dependent on how fast your connection is. A laptop needs greater bandwidth than a mobile device does, so your phone can load pages faster on a slow connection compared to a desktop. The shared internet being slow on your laptoo has nothing to do with your phone, rather its because the internet coming from your network has limited bandwidth and is slow.

    Is this something that I need to talk to my provider, Orange, about.

    If yes what would be a reasonable bandwidth to request?

    Presumably they'll ask for more money?

    Not really sure it has anything to do with any service they can provide as opposed to availability of service in your area. For example, in my school, my provider (Globe Telecom) has strong signal for calls, but weak 3G/HSDPA signal, so internet is crap, ancient dial-up speed. But about 200m away in my dorm, I can tether at about 2-6mbps. It has to do with service availability in the area.

    Thanks very much. I'm living and learning ..

    Is there a way for me to see the available strength on my phone?

    Meaning can I walk or drive down the street and see when it's strong or weak.


    P.S. I talked to Orange today and they said the problem is because they are making changes to the system.

    I just read this which may be interesting or boring ..

    Most people who own smartphones find themselves at some point asking why it is that Internet access for their Smartphone is so much slower than when they get on the Internet using a computer connected to Internet from their cable company, or some other broadband service. After all, in many cases it costs more to cruise the Internet on a Smartphone, and then there are all those all the television commercials from service providers declaring how fast their networks are; so what's the deal? As it turns out, it comes down to the fact that there are two completely different types of technology involved and each has evolved at a separate pace.

    First of all, the Internet access offered by your cable company is based on a high speed direct link using a well understood technology called Ethernet. Data is sent back and forth on a wire though very fast circuitry. Smartphone signals on the other hand, as is noted in a Radio-Electronics article describing the history of the cell phone, have to get where they are going by traveling through the air using radio waves. They also rely on cell towers to not only catch those radio signals emanating from a cell phone, but to pass them on to another cell tower, which in turn passes it on to the next tower, over and over again until the signal makes its way to a receiving station where it is forwarded to its true destination. All that forwarding takes time.

    But, according to Stephen Temple, one of the early architects of the cell phone system, in his online book the History of GSM, it's also about the history of circuitry used in both cell towers and phones. He says that because cell phone circuitry is still so much newer than circuitry used in computers it just hasn't had time yet to evolve to the extent that regular computer networks have.

    Temple says that when cell phones were first invented, they used analog signals. Thus, very basic sound-based circuitry was used in the cell towers and of course in the phones. But then, several years in, people discovered they wanted to do things besides talk on their cell phones. First there was messaging, then email, and eventually all of other stuff we have today such as Internet browsing. Making all this work meant revamping the entire cell phone infrastructure. Every cell tower had to be changed to allow for the transmission of digital signals, and new "smart" phone technology had to be invented to make it all work as well.

    Once the conversion was made to so-called 3G technology, it was discovered that the amount of data and the speed with which it could be sent wasn't up to what users were demanding for high speed Internet access, thus work began on a so called fourth generation (4G) technology that could be used, increasing data speed a hundred-fold. Unfortunately, this new update in technology means once again updating all the cell towers and incorporating new circuitry in new Smartphones, which of course takes time.
    And that's where we are today, sitting on the precipice of a new giant leap in Smartphone data speeds. Once the transformation occurs, over the next year or so, all new Smartphones will have faster data speeds than people will find on their computers at home and people will no longer have to wonder about the discrepancy.
