China Closing the Door to New Technologies

2013 may be a promising year for global trade in technology with the kick-off of the International Technology Agreement expansion discussions, the Trans-Atlantic Trade and Investment Partnership, and as the Trade in Services Agreement gets going. But China calls its own tune, and is now threatening to restrict its market for Internet-enabled technologies through a clever device that could cost its trading partners billions.

Can We Create a Secure Caller ID For VoIP?

Can we create a "secure Caller ID" for IP-based communications, a.k.a. voice-over-IP (VoIP)? And specifically for VoIP based on the Session Initiation Protocol (SIP)? Can we create a way to securely identify the origin of a call that can be used to combat robocalling, phishing and telephony denial-of-service (TDOS) attacks? That is the challenge to be undertaken by the "Secure Telephone Identity Revisited (STIR)" group meeting tomorrow morning, July 30, 2013, at 9:00 am in Berlin, Germany, as part of the 87th meeting of the Internet Engineering Task Force (IETF).

Why the Opus Codec Matters - Even if You Don’t Care About Audio

What makes the Opus codec so interesting? Why is there such a buzz about Opus right now? If you are not in telecom or doing anything with audio, why should you even remotely care about Opus? In a word... Innovation! And because Opus has the potential to let us communicate with each other across the Internet with a richer and more natural sound. You will be able to hear people or music or presenters with much more clarity and more like you are right there with them.

The Internet: Missing the Light

Today's Internet is wonderful for solving hard problems such as connecting to Amazon to buy goods or for using Netflix. Amazon and Netflix, among others, demonstrate what is possible if you put in enough effort. Yet if we are to understand the Internet we need to look beyond those applications to the simplest application such as sending one bit of information from a light switch to a light fixture.

The Bandwidth Bank

This is a topic that we have discussed on several occasions over the last decade, but it now seems as though things are slowly moving forward. A new company, Intabank, has set up a service whereby its enterprise customers can pool bandwidth that the intermediate company can then use to sell to other customers; enabling organisations to monetise their network connectivity assets.

Urgent Need to Revisit Internet Governance (WCIT-12)

Developments over the past few months - and especially the revelations about the spying work of the NSA on friendly governments and their people and businesses - show how important it is to try and establish some high-level strategies relating to managing the governance of the internet. While companies like Google have been lobbying hard against WCIT-12 - basically because they are opposed to any government interference in the internet - the reality is that, clearly without their knowledge, their own American government through the NSA is already directly interfering in their network.

FCC Change of Chairman: Opportunities to Advance Telecoms in America

It is always the case that change brings with it new opportunities, and the change in the FCC chair will be no exception to this rule. But we have learned since President Obama came to power that we should not have too high an expectation of such a change. In my discussions with the US Administration, the White House and the FCC I have never come across any major disagreement about my views on the future of telecommunications.

The Issue of Market-Initiated Competition in Telecoms

Many political discussions are taking place all over the world about how to best stimulate national or provincial telecommunications infrastructure investments against the background of current market dynamics. In this context the question often revolves around whether there is a market failure and, if so, does the government have a role to play here to address the matter, or can it be left for the market to sort out.

The Cable Show Experience

I had the opportunity this week to take part in the National Cable & Telecommunications Association (NCTA) Cable Show - a traveling show in the U.S. that took place in Washington, DC, this year... In the U.S. capital, it's difficult to avoid the topic of politics and its effects on the telecommunications industry. This was especially true during The Cable Show in light of recent news around communication monitoring, wiretapping, and how far it's going.

The Pros and Cons of Vectoring

Vectoring is an extension of DSL technology that employs the coordination of line signals to reduce crosstalk levels to improve performance. It is based on the concept of noise cancellation: the technology analyses noise conditions on copper lines and creates a cancelling anti-noise signal. While data rates of up to 100Mb/s are achievable, as with all DSL-based services this is distance related: the maximum available bit rate is possible at a range of about 300-400 meters.
