    8310 (AT & T) and tethering questions.

    Advertisement



    Recently have made the decision to buy a new laptop because of some increased travelling that has come into my schedule and need some mobile internet options.

    Been weighing the decision between getting an PC Broadband card or tethering to my BB 8310. Price wise it would make sense to add on a tethering package to my BB vs. buying a PC card and adding a two year contract for a second device.

    Would I get the same speeds on my BB as a modem as I would if I was using a PC card. Assuming I was in an area that gave me optimum signal?

    Would my laptop charge my BB as it was acting as an modem or data device?

    I guess while on the topic because I am considering using my BB as a modem. I currently have my desktop manager on my work computer. Can I install and use DM on both my work computer and personal laptop for the same BB (8310)?

    The disadvantage to using your BB as a modem is you cannot receive phone calls or messages while tethering. You would get the same speeds (unless connected via Bluetooth) as the PC card though.

    Your laptop would charge your BB as it was connected and you can use DM on both but you may end up having some sync issues with data going back and forth between the phone and two different computers. You could set it up though to where your phone was always exporting to say, your laptop DM, and always syncing both ways with your PC.

    Good luck making a decision...

    I have to disagree you can use your bb for phone and message during tethering. It will also charge while connected. It is my prefered method of wireless connections

    I didn't say you couldn't use the phone while tethered, I just do not receive messages or phone calls while in "Modem Mode".

    On GSM you can recieve phone calls and messages while tethered, CDMA has the limitation that data and voice can not be transmitted at the same time.

    Also depending on the carrier, the speeds can be half as slow as an aircard.

    This is 100% incorrect. You can NOT receive data and phone calls at the same time on GSM or EDGE. You need 3G HSDPA in order to do this which the Blackberry Curve does NOT have. However most of the time, when phone call is coming in, the phone will STOP the data connection and ring. You will not be able to use the device's data connection while you are on a call.

    That's interesting since I have seen proof defying what you are stating. The data connection gets seriously slowed down but I have seen a tethered laptop with a BT headset being used while a call was in progress. I know on a Blackjack (not the one I saw connected) the data speeds do not change enough to be noticed while on a call but on an edge device they slow down considerably (enough to cause a timeout in some situations) but don't actually stop.

    I'm not sure how you saw this being that it is physically impossible. The ONLY way this would be possibly at all is if the GSM/EDGE device had dual radios built in which almost no phone in the US has.

    I went back and did some asking since it had been a year since I had seen it done and found that the phone (memory was sketchy on the model) was a European V3i. He was able to surf the web and recieve a phone call without the data connection being dropped using T-Mobile's edge network here in the states. I needed to do the same thing last night on my BB with no success. It is definitely phone dependant since technologically speaking the system is capable of performing this feat according the the GSM standards.

    I use my 7105t (GPRS) as a tethered modem almost all the time... like, right now. It keeps on receiving mail as well as phone calls, and I can even send mail from it if I want to (useful when Yahoo or Gmail are slow to load). I do think on one occasion I made a phone call as well.

    As Dennis Ritchie said once, an Operating System is just a glorified I/O multiplexer
