In my September 18 blog posting, I wrote, “One of the mobile operators will likely see this [HD Voice] as a differentiator. It could be the one with the largest market share (to put pressure on the others) or it could be the upstart (to carve out their niche better). Or it could be that peer to peer HD Voice is impacting all of them and one wants to compete better. But whatever the reason, a mobile carrier deploys it. This operator is The Disrupter.”
And the Disrupter potentially is Orange Moldova, who announced HD woice service in that country on September 9. (9/9/09!) Within The Disrupter’s network, you can get HD voice. But if I call you on your mobile phone, and you are not in their network, it won’t work. And if I call you on your PSTN line, it won’t work. You have another one of these islands. So then what happens?
Most probably, the network operators who have deployed HD voice make agreements to transfer HD voice from one network to HD voice on another network. Why would they do this? Keep the differentiation. Keep the peer-to-peer calls just that. And clearly the PSTN operators can’t compete with this.
What do we need in the network infrastructure then? We need multimedia servers to play announcements, voice mails, etc. in HD voice. We need the multimedia servers to play music in HD format so we need them to support the appropriate codecs, and we would need the applications that reside/utilize the multimedia servers to utilize the codecs.
From an infrastructure perspective, we’d also need gateways that support codec to codec transcoding and signaling. This would be mobile HD codec to enterprise HD codec and also mobile network-to-mobile network. We’re also going to need multimedia servers and gateways that can translate from HD to narrowband and vice-versa since there won’t be an all HD world for a long, long time, if it ever comes at all..
As the HD voice infrastructure is deployed, we need to integrate HD voice in with the PSTN as the operators can’t ignore that, since they can’t just stay on the island. So the value proposition goes up as HD voice gets a wider voice network.
How long will this all take to start to take off? This is hard to say. That’s really what the HD Voice Conference is about. And the HDConnect organization. But clearly the mobile operators hold a big key.
Why have I written four blogs about this in this timeframe? The HD voice conference certainly spurred me. But when describing the products above, all of these are where Dialogic plays. This is why Dialogic has an interest in HD voice and is working actively now to integrate HD voice functionality into our products. This is just a natural evolution of our products.
We know multimedia server platforms, and we know gateways. We know how to use codecs, we know how to do echo cancellation, and noise suppression, and gain control and handle jitter and packet loss. With HD voice, these algorithms will be all the more important since use of poor algorithms will result in a less than good user experience. Dialogic’s 25 years of experience here will make a difference. I know I’m the senior vice president of marketing here at Dialogic, but I really do believe this.
For more of an overview of HD Voice from the Dialogic perspective, please see our white paper.
I’m sure I’ll be having more to say on this in future blogs.
