While I was writing this blog, I realized today’s date, the 9th day of the 9th month of year 9 is somehow significant.  How?  Well, today is the last day of single digits in a date format (9/9/9) for 1001 years!   I don’t know exactly what happened on September 9th, 1009, but today it looks like Apple is having some big event with lots of speculation about the “announcement” and the Beatles have a remastered album coming out.  Undoubtedly, this is all timed to fully maximize upcoming holiday gift sales.  So in 1001 years when someone Googles 9/9/9, because of the internet, they’ll be able to find out exactly what happened today, and hopefully they’ll see that because of these must- buy holiday items, this was the tipping point to end the 2008/2009 financial crisis.  Times, they are a changing…

Yes, they are changing.  And in our voice communications world, Hi Definition (HD) Voice is a disrupter to the status quo.  Not quite on the scale of Voice over IP, but a disrupter nonetheless.   Before I get to that, let me do a brief overview of what HD Voice is. 

HD Voice allows for a wider spectrum bandwidth (from 50Hz to 7000Hz) than traditional voice (300Hz to 3300Hz); therefore it’s also known as wideband voice.  This allows a better reproduction of speech.  It also allows better reproduction of any sounds in this spectrum, so it should improve music (i.e. ringtones).  We are very used to talking on narrowband, but once you utilize a wideband codec, you can immediately hear the difference.  The most popular codecs have names like G.722, G.722.1, AMR-WB, RTAudio (utilized by Microsoft in OCS) and Silk (utilized by Skype).  I use Microsoft OCS in everyday internal conversations at work, and it does sound very good.

Therein lies an issue with more widespread acceptance though.  I use it at work.  While we have many locations in Dialogic, we are all connected via WAN and VPN.  We are our own little network.  Our own little island if you will.  On that little island, we can talk easily utilizing VoIP and wideband codecs.  But once you have to get off that island, or get onto the PSTN or the mobile network, you have to lose the wideband.

Ah, the mobile network.  Some of the codecs I described above are more applicable to the mobile network.  Having wideband codecs on the mobile network will be the real disrupter.  I will discuss this more in next week’s blog.  

By the way, next week I will be attending the HD Communication Summit in New York.  Brough Turner of Dialogic will be moderating a panel there on Mobile HD VoIP.
