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
Ahh, so the telecom incumbents have come up with a "new" idea for the Internet -- usage-based pricing. That's right, more usage (for things like VOIP and video especially) means more costs to operate the network, so users should pay by the bit, or some similar metric. It's all so logical! But wait a minute. I thought what sparked the consumer Internet revolution was the fact that ISPs didn't charge by the minute, but offered flat-rate monthly fees. And what catalyzed the boom in cellular usage here in the US was the shift from heavily usage-based pricing to the largely flat rates we see today... more
The Swedish carrier group Telia has recently announced the sale of its international wholesale business to Polhelm Infra, an infrastructure investment manager jointly owned by a number of Swedish pension funds. Why would a telco operator sell off what was a core part of its operation to a pension fund? The Internet was originally conceived as a telephone network for computers. (I should mention that this was not a concept that was unique to the Internet at the time. more
You can't open a newspaper today, listen to the radio, or watch TV without hearing about the enormous explosion in the use of telecommunications technology - be it fixed or mobile broadband, the internet, social media, smartphones, tablets, wearables, IoT, cloud computing, the list is endless... Yet, at the same time, many telcos and ISPs are struggling to maintain their profitability. This defies economic logic. more
The new Clearwire could be game-changing, but the rules of the game may not be quite as Clearwire presents them. I have been wondering since last July whether something significant would happen in the Google/Sprint world. The deal announcement earlier this weekseems to be that key development... In a nutshell, Sprint will contribute its substantial spectrum licenses in the 2.5 GHz range and its WiMAX-related assets and intellectual property. Google, Intel, Comcast, Time Warner Cable, and Bright House Networks will invest a total of $3.2 billion. more
The announcement yesterday morning in the Times that New York State AG Andrew Cuomo had reached an agreement with three US network operators (Verizon, Sprint, and Time Warner) about blocking child pornography was both less and more important than it appeared. It's less important in that part of the agreement covers something ISPs already do... more
It's no secret that Comcast has been leading the charge of DNSSEC deployment among ISPs. For the past couple years, Comcast has been testing and pushing for the widespread adoption of DNSSEC. In the spirit of increasing adoption, I thought I would interview the DNS gurus at Comcast to see what they've learned and what advice they would give other ISPs considering DNSSEC deployment. more
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
In a post today on Comcast's blog, Chris Griffiths, DNS Engineering Manger, has informed customers that they have begun to role a DNS redirection service -- a controversial service offered by several other ISPs over the years to redirect mistyped URLs to ad-based pages instead of a typical 404 error page. The service called "Domain Name Helper Service" is being launched as a market trial in Arizona, Colorado, New Mexico, Oregon, Texas, Utah, and Washington according to the company. more
One thing was clear from a recent presentation by the new leaders of the SF-Bay Internet Society (ISOC) Chapter Working Groups: inclusion and collaboration will be the key to these groups' success. As Dr. Brandie Nonnecke, the Internet Governance Working Group (WG) Chair said, "We haven't yet cracked the code on what 'multistakeholder' means." But that won't stop her and Dr. Jaclyn Kerr, the Data Protection, Privacy, and Security WG Chair, from trying. more
This never-ending story is used by opportunistic telcos and their lobbyists to confuse the issue in order to gain regulatory or political advantage. The debate is now raging again in the USA. In an attempt to talk down their monopolistic position in the market the three telcos - and this time in particular, Comcast - are claiming that real competition does in fact exist in the American broadband market, citing competition from the mobile 4G LTE services as an example. more
Bandwidth is the basic foundation for Internet traffic as a connector to everything important in our lives. Whether it is basic bandwidth for connecting to family and friends, or a super fast highway for global reach and competitiveness in the business world, bandwidth constitutes the speed at which we connect as a global presence within the expanding sphere of Internet communication. ... To understand why bandwidth is important to all Americans, including personal and business uses, we must understand the different types Internet traffic. more
So, the FCC will recommend that Comcast be "punished" or receive "sanctions" for its peer-to-peer throttling practice. And the network neutrality debate goes on, as does its ambiguities and vagueness. Even if you hate Comcast and agree with the net neutrality argument and the FCC's decision, one thing Comcast is correct in saying is that "reasonable network management" specified by the FCC in network neutrality policy set in 2005 is vague. Actually, the term "network management" by itself is broad before you even try to interpret what is meant by "reasonable", and it is not exactly correct in its application here... more
Humanity continues to find itself at a crossroads. Ahead of us lies an uncertain future filled with predictions of imminent doom and ominous prospects along with the wonders of science and technology. Behind us lies a century marked paradoxically by both devastating global conflicts and unparalleled global collaboration. As societies continue to globalize, we are increasingly becoming more connected - to the point where it is difficult, if not impossible, to divorce ourselves from the interconnectivity in contemporary systems of commerce, economics, politics, and culture. more
Making a telephone call in London has become more difficult for early adopters of the new iPhone 4. First of all the reception is rather poor. And it is not just that it is not showing the bars correctly; many users in congested mobile areas such as London receive the message 'server not available'. (As a matter of fact, this doesn't apply only to the iPhone -- it is also experienced with other smart phones.) more
