IPv6 and LTE, the Not So Long Term Evolution?

The Wall Street Journal reported that AT&T saw wireless networks about to drown under a deluge of data. To see YouTube content uploaded form an iPhone or Slingbox rerouting a favourite television program to your smart phone gives mobile network operators the shivers. Skype over 3G in the meantime gives sleepless nights, not because of surging megabyte floods but due to nightmares of considerable voice and roaming revenues washing away. Not easy to plan and engineer "managed transitions" under those circumstances. more

The Addressing System for the Next (Wireless) Internet

I gave a talk yesterday at Northwestern called A DNS in the Air. My idea is that, in order to scale, the emerging wireless Internet needs something analogous to the domain name system (DNS) -- the infrastructure that allows you to reach sites across the Net. Billions of mobile phones, and even more billions of connected sensors and other wireless devices will completely overwhelm our current spectrum management regime. AT&T Wireless estimates we will need between 250 and 600 TIMES the current wireless capacity in 2018, less than a decade from now. more

Satellite Broadband, Stimulus Funds and Network Neutrality

At the IP Satellite Summit in Washington this week, a panel composed of satellite service providers and product vendors discussed whether or not they would pursue the economic stimulus funds set aside for broadband development. While the service providers agreed that there are viable business models for satellite broadband service without the stimulus money – of course, they were delivering service before the current economic collapse and talk of the stimulus money – the consensus seemed to be that they would apply for the grants to further develop, deploy and perhaps even subsidize their service offerings... more

Can’t Connect… Won’t Connect

BBC technology correspondent Rory Cellan-Jones must be hoping that his near neighbours don’t decide they want a larger family. He recently spent ages setting up a high-speed wireless network at home, documenting the whole tortuous process on the BBC Technology blog, but all his hard work could apparently be ruined by a single baby listener in the neighbourhood... more

Exploring the Roots of Wireless Spectrum Controversy (eComm Panel)

Earlier this month, I had the opportunity to attend the The Emerging Communications (eComm) 2009 conference in San Francisco which was packed with 3 days of fascinating conversations about the future of communications. I absolutely enjoyed talking to various speakers and attendees giving me a deep level of appreciation and perspective on technical, commercial and political issues at hand -- and what is likely to come in the next few years. And speaking of politics, Lee Dryburgh, who founded eComm in early 2008, has generously allowed us to share with you a fascinating panel discussion which took place on day 3 of the conference called "Spectrum 2.0 - What's really happening?" more

WiMAX vs. LTE

Mobile WiMAX, with the release of 2×2 MIMO chips in 2008, gives WiMAX a lead of two or so years on its major competitor -- the 3GPP's LTE. However, 3G cellphones using 3GPP UMTS technologies, extended to higher speeds with HSPA, is widely used in handsets in many countries. In North America, 3GPP2 CDMA2000 and EV-DO are widely used, but these are likely to be replaced over time by LTE and to some extent WiMAX. more

Why You Needed to Be at eComm 2009

I've been posting photos and snippets during eComm 2009 this week, but composing my overall impressions has been another matter. Sitting through 3 days mostly filled with continuous 15 minute presentations is a surefire recipe to fry your brain, and most people I talked to were topped out well before things wrapped up Thursday night. It's information overload of the highest -- and best -- order... Here's my top-line takeaway, and reading the rest of this post is really just detail. But it's detail you'll probably love if you really want to know what you missed... more

Achieving Connectivity vs. More “Broadband”

Our problem isn't the lack of capacity -- it's our inability to achieve simple connectivity. We have abundant capacity but can’t use it because we have gatekeepers who set a price on our ability to communicate and innovate. If we were able to take advantage of what we already have we would find ourselves with a wealth of opportunities rather than having to pay billions to "stimulate" the gatekeepers into letting us create new value. more

HTTPS Web Hijacking Goes From Theory to Practice

I've been privately talking about the theoretical dangers of HTTPS hacking with the developers of a major web browser since 2006 and earlier last month, I published my warnings about HTTPS web hacking along with a proposed solution. A week later, Google partially implemented some of my recommendations in an early Alpha version of their Chrome 2.0 browser... This week at the Black Hat security conference in Washington DC, Moxie Marlinspike released a tool called SSL Strip... more

FttH Boom in North Asia

In the mid-year 2008 rankings by the Fibre-to-the-Home (FttH) Council, South Korea, Hong Kong, Japan and Taiwan occupy the top four positions in terms of household penetration percentage. Asia Pacific now accounts for more than 27 million of the world’s 32 million FttH connections. more
