Sustainability in Communications Technology (CT) equipment, infrastructures and operations, including telecom, broadcast, & networking

Green Touch: New Communications Industry Initiative

I have long advocated for more attention to the "CT" side of Green ICT. Green Touch is a new industry initiative organized by equipment manufacture Alcatel-Lucent that strives to do just that. It declares:

Is the Industry Educating Broadcasters About Green ICT Issues and Opportunities?

The television broadcast segment of the telecom industry is at the focus of many Green ICT issues, ranging from the e-waste implications of global analog-to-digital conversions to rapidly evolving technologies for studio lighting. Despite the challenges, there is upside here for media enterprises. How are industry conferences preparing broadcasters and others for the challenges and opportunities of Green ICT? I took a look at broadcast conferences around the world.

TV E-Waste Around the World: UK, Vietnam, Hotels, Australia

The DTV conversion is gaining momentum worldwide, along with e-waste problems and solutions.

iPhone: Data-Guzzling Hummer?

We learned that the 11 billion consumer devices attached to our global ICT infrastructure is expanding the Green ICT focus outside of the core. Now, there is growing awareness how device use can impact the energy consumption and carbon footprint of the network and core. Jenna Wortham writes in The New York Times:

Can Flow Routing Reduce Power Consumption and Improve A/V Performance?

ARPANET pioneer Lawrence Roberts notes that "we’re seeing an explosion applications...[but] traditional IP packet routers...treat the video packets as loose data entities when they ought to treat them as flows." He advocates 'flow routing' to improve network routing and to reduce its power consumption, claiming that "in a traditional router the routing and queuing chips consume 80 percent of the power and space".

Carbon Footprint of a TV Station's Viewers

The search for data about TV stations' energy consumption elicited a comment from an industry colleague that it is "miniscule" compared to that of the station's viewers. How would we go about calculating the impact of a local station audience?

Bandwidth Crunches, Demand Forecasting, and Paid Content

Many reports that are publicized on Vertatique and elsewhere are free, but some are from paid content providers. It becomes difficult to evaluate these when all one has are the publicity assets, which by their nature tend to raise more questions than they answer. A recent prediction on trans-Atlantic bandwidth capacity, picked up by the popular media and amplified in the tweet-o-sphere, provides a case in point.

Broadcasters' Energy Consumption

An article in Broadcast Engineering seems to imply that for most terrestrial broadcasters, their production studios consume more energy than their transmission chains (master control, STL, transmitter, tower, etc.). It would be useful to see the data on this, as this has bigger implications for the media industry than just Green ICT.

EU Standards: WEEE, RoHS, and more

EU Waste Electrical and Electronic Equipment Directive logo European Community Directives are being increasingly used by manufacturers to label their more sustainable products. Here's a quick review of 3 key directives and 5 codes of conduct:

Broadcast TV Entirely By Wind?

Multichannel News reported that "KNTV in San Jose . . . is powered entirely by wind". This article is widely referenced on the web, including in a Wikipedia citation. I was curious about this statement, knowing that the transmission operation alone for a terrestrial television broadcaster typically draws tens of kilowatts of power on a 24/7 basis.
