LTE and Spectrum Stupidity

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»

More Available Wireless Spectrum and Higher Market Entry Barriers

The tremendous demand for, and profitability of mobile telephony supports legislative and regulatory efforts to refarm spectrum with an eye toward reallocating as much as possible for wireless telephony and data services. But there is a downside that no one seems to acknowledge. In light of past FCC practice and the behavior of incumbent wireless carriers I expect two anticompetitive outcomes to occur with the onset of any more spectrum. more»

Verizon and Skype: Who's the Winner?

Until only recently, has it been remotely plausible to consider such different companies joining forces. I've written about Skype often, and for the most part, they've been a threat for incumbents of all stripes. To hear about this from Verizon during such a public event makes it very clear that the sands are shifting once more, and yet again, VoIP is the culprit. more»

Wireless VoIP: Loss Leader or Upselling Strategy?

Verizon Wireless' decision to allow their subscribers to access Skype raises a question about strategy. Is Verizon leveraging Skype access as an inducement for subscribers to upgrade to smartphones and commit to $30 a month data plans, has the company acknowledged that its future marketplace success lies in data and not voice services, and how will the company prevent a substantial reduction in plain old voice subscriptions priced above the $30 data plan benchmark? more»

Absolutely No Wireless Spectrum Shortage in 2010

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»

FCC's Genachowski Promises He's Not Out to Regulate Net, New Media

We learned from The Wall Street Journal yesterday that "Federal Communications Commission Chairman Julius Genachowski gets a little peeved when people suggests that he wants to regulate the Internet." He told a group of Journal reporters and editors today that: "I don't see any circumstances where we'd take steps to regulate the Internet itself," and "I've been clear repeatedly that we're not going to regulate the Internet." We're thankful to hear Chairman Julius Genachowski to make that promise. We'll certainly hold him to it. But you will pardon us if we remain skeptical... more»

Wi-Fi Offload, Not Femtocells

Mobile operators face soaring data demand. The natural evolution of 2G/3G/4G infrastructure delivers about 2X additional capacity every 24 months. That's a major disconnect! (At least) two solutions are on the table, Femtocells and Wi-Fi offload. Both approaches solve the backhaul issue by using customer or 3rd party links (DSL, DOCSIS, T1/E1, WISP or otherwise)... As a solution for mobile data capacity, Wi-Fi wins, for many reasons. more»

Sharing: The First Step to Structural Change in Mobile

The arrival of the iPhone, Android and iPad will raise the stakes higher in the mobile broadband market. The fact that iPhone alone has over 140,000 Apps over sort of open networks, not portals, shows the demand for mobile applications. This will put an enormous strain on the infrastructure of the mobile operators and will require them to build fibre networks to all mobile stations, as well as invest in more spectrum and new technologies such as LTE. At the same time the mobile subscriber markets are becoming saturated and competition is driving margins down. more»

The Greatest Free Riders of Our Time

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»

IPv6 or IPv4? What Will We See in the First Wave of LTE Networks?

All the talk early this year seems to be about LTE deployment to alleviate chronic Apple and other smartphones induced indigestion on the AT&T and other major Mobile Networks swamped by data traffic. The telluric shift albeit the user will not care or should not notice is that when he or she will power on that smartphone or whatever the communicating Swiss Knife will be called, it will request an IP address to complete an IP based call. more»
