    Half Duplex vs Full Duplex

    Advertisement



    You ever wonder why when you are listening on speakerphone on your BB and you try to interrupt the person and they keep talking? Its like they didnt even hear you say something. Its because most BlackBerries use half duplex speakerphones.

    Re: Half Duplex vs Full Duplex

    Im just so ready for a better speakerphone on my 7100i. I use this feature alot, it beats going in my pocket for my H700, waiting for it to connect, and its much louder on speakerphone anyways. I always have to interrupt people, benefits of my position, and they never hear me, until I take it off speakerphone and start yelling into the phone! Just thought I would bring this up because I know there has to be someone out there that feels me on this one!

    Sprint incorporates Full-Duplex into many of their devices. I cant seem to find the answer to if yours has it or not, but if you do, your in good shape!

    Re: Half Duplex vs Full Duplex

    I had that on my 7100t. I only used the speakerphone once and the only person I used it with kept telling me they couldn't hear me. This is one of the reasons I refused to use my third 7100t, and refuse to use my 7105t, as phones.

    Re: Half Duplex vs Full Duplex

    I called Sprint and for some reason those guys over there completely clueless. I was transfered around for better than an hour before I finally got to someone who wasn't a clueless as the others; that was until he went to put me on hold and hung up on me. Nevertheless, I'm no better off in finding an answer than I was before my adventure. I'll search around and post back here if I'm successful.

    Re: Half Duplex vs Full Duplex

    I feel ya cl. 2 days after I got my 7105t (after waiting 2 days for the phone to provision itself then realizing I had the WRONG sim card in the phone. I put the one in that came with the phone instead of transferring the one from my Sidekick 2 to the BB LOL...this was resolved when I realized that), I had a T-Mo BB rep hang up on me while trying to activate my BIS account because I had major interference from the house phone my parents use and my line. 2 days, 4 reps and 6 hours after the phone lines got screwed up and straightened out, I had my BIS account LOL

    Re: Half Duplex vs Full Duplex

    and Sprint wonders why their profits are down 38% for the last quarter...they are blaming it on the merger but Nextel is doing fine...but unfortunately the Sprint side of the house is gonna bring bad light to the Nextel side...
