Story: Skype calls on FCC to open network access
The wireless industry needs to wake up...
[quote="MAP2010"]VoIP is the next step in the world of wireless, so many people miss understand what its all bout and why its the next step.
You would need to understand what is VoIP and why High Speed Networks will use it, Voice channels will no longer be needed and be replaced my VoIP.
First we must understand that as it is right now CDMA EV-DO rev (O) and now rev (a) its data or voice, now because data is in packets you can sometimes get a call but thats not always, now if you used VoIP and some one called you it would be easy to get that call. See its both data and there is not need to use voice, we do not use VoIP with slower networks like GSM because its to slow for the data packet need to offer VoIP. But with EV-DO its just right, and if you want an easy transfer from Network (a) to Wi-Fi (b) you need VoIP for softhand offs. Why is this so? Because its based all on VoIP, other wise you can not get easy hand offs from Voice channels to VoIP data.
So maybe we should think about moving into the year 2010 plus and not about staying still in the 1960's.
Just something to think about.

Ok I have a question? So WCDMA/ UMT offer voice and data simultaneously. I agree with that. Now when we transmit data and voice wirelessly together ((HSDPA) like video calls I suppose, or mobile internet), we are bound to sacrifice some speed. I am ok with that too. So what problems can we face with HSDPA. I hope it’s not a perfect solution. HSDPA and EV-DO do similar tasks and their download speed is almost similar. The only difference is the transmission of voice and data together wirelessly. So, just because of that HSDPA becomes better? There must be some kind of really bad news for HSDPA. Is there any?
* HSDPA is software which pushes speed higher. Does HSDPA help to combine voice and data?
