VoIP Cell Phones Coming

Posted by timothy on from the when-oh-when dept.

bp33 writes "Wireless Newsfactor is running a story about how the wireless vendors are climbing over themselves to get Voice-Over-IP cell phones. You might ask "why bother? We already have wireless voice now." But with an open platform for wireless (Symbian, JavaPhone etc), your "voice" (er .. audio) just becomes bits that your programs can manipulate before sending."

  1. Latency & Jitter by chill · · Score: 5, Insightful

    Voice uses circuits for a reason -- latency and jitter *must* be controlled or the conversation goes to hell.

    There has to be more to wireless VoIP than simply 3G+ data -- it must be able to control the timing of the arrival of packets.

    No, you can't buffer it. Voice conversations are realtime interactive. Fat packet sizes don't help, either. There is a limit to how long you can spend processing the data into and out of a packet before you screw up the timing.

    They have a LONG way to go before this will be realistic.
