80% of Mobile Calls Go to Just 4 People

"Although mobile phones make it easier to keep in regular touch, a typical user spends 80 percent of his or her time communicating with just four other people," says Stefana Broadbent, an anthropologist with the User Adoption Lab at Swisscom. Think of it as the long tail of communications.
.
Broadbent also says different channels get used for distinct reasons. Mobile calls are for last-minute coordination. Texting is for “intimacy, emotions and efficiency.” E-mail is to exchange pictures, documents and music. IM and VoIP calls are “continuous channels”, open in the background while people do other things.
.
Also, you won't be surprised by this finding, but texting is on the increase. “Users are showing a growing preference for semi-synchronous writing over synchronous voice,” says Broadbent.
And though enterprise IT managers might not like the idea, private communications are invading the workplace. Workers expect to be plugged into their social networks while at work, whether by email, IM or mobile phone.

iPhone Breaks Record


Google and GrandCentral

Some might see this as competition for Skype or Jajah (I use both), and there is some logic to that notion. For the most part, I don't see it that way. Google now is a provider of unified communications. That's the story.

Comcast says it Could; Not "Would"

“We’re not necessarily saying we want to offer 100 or 160 megabits” per second access speeds, says Comcast CTO Tony Werner, referring to the DOCSIS 3.0 upgrade Comcast is planning. Using channel bonding, DOCSIS allows a cable operator to support downstram bandwidth as high as 480 Mbps and upstream as high as 120 Mbps, on a shared basis.
And that’s the key. Two bonded TV channels (6 MHz each) will support that amount of bandwidth from a fiber node to customers served off that node, possibly an area of 500 or more homes in any given location. At 60 percent video penetration and 30 percent cable modem penetration, that implies a potential customer base of about 90 homes or businesses.
If three customers really wanted 150 Mbps downstream and 40 Mbps upstream, that would chew up 12 MHz of bandwidth, equivalent to two analog TV channels.
So unless a cable operator wants to reclaim a fairly significant amount of television bandwidth, it isn’t going to be able to provide such speeds to more than one or two customers in a fiber-served area.
The DOCSIS 3.0 upgrade is supposed to start in 2008.
