Mobile operators are counting on Long Term Evolution (LTE) technology to handle surging demand for mobile data access. But LTE developers made some poor choices, cutting spectral efficiency and thus driving up operator costs. LTE was envisioned as an all IP system, but the RF allocations follow the voice-centric approach of earlier generations. While LTE standards allow for either Frequency Division Duplexing (FDD) or Time Division Duplexing (TDD), all initial LTE equipment uses FDD. FDD requires two separate blocks of spectrum... more
Sure the iPhone has problems, but John Stankey of AT&T thinks restoring a $2B capex cut will fix them. It may take a little more money than that, but Glen Campbell of Merrill Lynch has confirmed he's on track. In a 50 page report that's one of the best I've read in years, Merrill destroyed the common belief that wireless has a significant spectrum shortage. more
Former Southwestern Bell CEO, now General Motors CEO Ed Whitacre famously accused Google of free-riding his network, despite the obvious truth that Google pays for traffic delivery to peering points and ISPs gladly enter into reciprocal peering agreements in lieu of cash transactions that would likely result in a near zero payment as roughly equivalent traffic balances out. Mr. Whitacre did raise a legitimate question whether there are free riders and I'm seeing one darling and one unexpected group flying below the radar. more
The FCC has posed a number of provocative questions to AT&T regarding the fact that iPhone subscribers cannot download and use the Google Voice application. AT&T should stifle every motivation to play cute or clever with the FCC. Apple adopted such a strategy when it suggested to the Library of Congress and others that it would be curtains for the free world if iPhone owners could hack, jailbreak, tether, and otherwise use their handsets without fear of violating the prohibition on circumventing copyright laws contained in the Digital Millennium Copyright Act. more
Who would dare to predict the year the Internet will reach 50 billion addressable devices? Thomas Noren, head of LTE product development at Ericsson sees one day 50 billion devices shouldered by LTE. He sees LTE as the truly global standard putting to rest the long and acrimonious rivalry between CDMA and GSM protagonists and even sees the Chinese third way with their TD-SCDMA aligned on LTE. Mobile WiMax is, in his mind, already relegated to the dustbin of history... more
Cell phone carriers have seen a huge growth in wireless data usage. The iPhone is selling like hotcakes, and its users generate large amounts of traffic. Not surprisingly, as cellular providers deploy faster network technologies, users generate even more data... more
It's official. A team of market analysts from Oppenheimer are saying [PDF] what I've been saying since 1997, that the apps are separating from the network, and this is driving a wave of "explosive innovation." more
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
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
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
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
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
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
The telecom industry five years from now will be unrecognizable. The creative destruction of the Internet broadly writ will be even greater than it has been in the last decade. The major telcos, the major television networks, and the major cablecos -- if they still exist at all -- will have very different revenue models than they have today. That's the good scenario... more
In fact WiFi (technically standard 802.11) and WiMAX (802.16) don't compete for broadband users or applications today. That's partly because WiFi is widely deployed and WiMAX is still largely an unfulfilled promise and partly because the two protocols were designed for very different situations. However, if WiMAX is eventually widely deployed, there will be competition between them as last mile technologies. Some people describe the difference between WiFi and WiMAX as analogous to the difference between a cordless phone and a mobile phone... more
