IPv6 Over Satellite: Pie in the Sky?

I am writing this from the Satellite 2008 conference in Washington, D.C. As I make my way through the exhibits, I see many vendors advertising IP capabilities in their hardware products or network services. But when asked about IPv6 support, the common reply is a not so believable "it is on our roadmap" followed by a somewhat vague delivery date. Although IPv6 development has been slow across the board, it appears to be moving even more slowly in the satellite world... more

Call for Telecom Industry Wake-Up

As many of you know, I'm launching the Emerging Communications (eComm) conference -- taking place next month in Silicon Valley, at the Computer History Museum. Communications innovation has been stagnant, in my opinion, for nearly a decade. Telecommunications and Internet communications both seem to be at somewhat of an impasse. The communications industry needs a forum to help break through the stagnancy and highlight the huge opportunity space that is emerging. The stagnancy has been strikingly more so in telecommunications... more

As the Comcast Saga Unfolds, Be Careful What You Wish For

Comcast has been in the news recently for deliberately "slowing down" some subscribers and applications in its broadband cable service. There was an article in the Washington Post today updating the case, and there was a recent article in Network World that actually favors the groups filing the complaints and calls for the FCC to crack down on Comcast. more

IPv6: Do as I Say or Do as I Do?

How important is it for a vendor, service provider or integrator to be using a service or technology that it is pushing on its clients? When Voice over IP (VoIP) came out Cisco began a gigantic push, having its salespersons pitch it to anyone and everyone on their client list. But Cisco had not yet deployed VoIP within its own corporate network. It was still making use of traditional voice systems from vendors that today it probably considers competitors. Many people on the receiving end of a sales pitch recognized this... more

iPhone, Android, 700 MHz: What Maximizes Wireless Innovation?

At the Emerging Communications Conference eComm 2008, I'm moderating a panel "Wireless Innovation, with or without operators." This will be a discussion -- smart people from differing camps responding to (hopefully) probing questions from yours truly, and the audience. Points of view represented include Google Android, J2ME/JavaFX Mobile, iPhoneWebDev.com, Skype and Trolltech Qtopia (Nokia), plus Chris Sacca, formerly head of Google's wireless initiatives. I've been thinking about subjects and questions for the panel. As a start, I'll set down my current views, then seek others' views and questions. more

Up to 300 Megawatt Worth of Keepalive Messages to be Saved by IPv6?

The Time Square Ball bringing in 2008 had more than 9,500 LED bulbs displaying 16 million colours while consuming power equivalent to about ten toasters. This compares to 600 incandescent and halogen bulbs adorning last year's Ball. Easy to forget that most mobile devices used by Time Square revelers were behind IPv4 NAT's and that always on applications such as Instant Messaging, Push e-mail, VoIP or location based services tend to be electricity guzzlers. It so happens that applications that we want always to be reachable have to keep sending periodic keepalive messages to keep the NAT state active... more

Verizon OPEN Wireless

Very surprising and welcome announcement from Verizon Wireless yesterday announcing that "it will provide customers the option to use, on its nationwide wireless network, wireless devices, software and applications not offered by the company. Verizon Wireless plans to have this new choice available to customers throughout the country by the end of 2008..." And Verizon Wireless is right to open up. There's plenty of room to be cynical about this; after all, Verizon Wireless is trying to STOP the FCC from putting an openness requirement on the 700Mhz spectrum to be auctioned... more

The Third Stage of the VoIP Rocket Never Fired

Ten years ago was the dawn of Voice over IP (VoIP). The pioneering Israeli company VocalTec had just released its VoIP software for PCs (it was named iPhone, BTW). Industry guru Jeff Pulver (whom I now partner with in FWD) had begun to hold his Voice on the Net (VON) shows. As the founder of VoIP startup ITXC, I was invited to give a keynote at VON in Boston. The evolution of VoIP, I opined with the requisite PowerPoint slides, will be like a three stage rocket. I was right about the first two stages and dead wrong about the third... more

Walks Like a Telco, Yalks Like a Telco… Must be a Telco

Vonage's latest woes are written up by Om Malik in Vonage: How Low Can You Go. More interesting than Om's reportage (Sprint wins case, Vonage ordered to pay damages, stock drops to $1.30) is the commentary afterward, in which one reader takes Om to task for the "gleeful" way in which he reports the demise of the VoIP companies... Boosters made the argument that VoIP was fundamentally cheaper than the TDM systems that phone companies deploy, and so therefore they enjoyed a price advantage in the market place. Anyone in the business of supplying telecom equipment, however, will tell you that the argument is flawed... more

Telephony is Disrupted Because Voice No Longer Matters… (As Much)

Does "voice" communication really matter as much today in business communications? Think about it. When you need to reach someone today, what do you do? Do you call them on the phone? Or do you send them email? Or a text message? or IM? I know personally that my normal communication flow usually goes something like this: Instant Messaging; I check first to see if I can reach the person on some form of IM... SMS; if the matter is relatively important... E-mail/Facebook/Twitter/other; Previously that would have just been email, but these days I find myself very often sending messages via Facebook or Twitter... more
