Bell Labs Says Networks Can Be 1000 Times More Energy Efficient 156

judgecorp writes "Bell Labs believes that data networks can be more efficient and has launched a consortium which aims to develop technology that uses only a thousandth of current network energy requirements by 2015. The Green Touch initiative is going to focus in particular on wireless, seeking to reduce wasted energy in signal broadcasts. Cynics might say Alcatel-Lucent is using its research division to distract attention from its troubles — the Financial Times described it as 'a poster child for much that is wrong in the telecoms equipment industry' — but Bell Labs still commands respect and support, and the goal it has set is an interesting one."

    Just how much power is being used for Cell transmissions? What about Wifi?
    Think about it. Our appliances are getting more efficient all the time but how much power are our gadgets sucking up.
    WiFi, Game Consoles, DVD players, Home networks, Home NAS servers, cable boxes, and TVs.
    Way back when when you went to bed you turned off our TV and it was actually off.

    I highly recommend this to everyone who has to pay an electricity bill: Unplug your appliances.

    I have saved over 60% of my electrical bill by following the simple process of unplugging everything when its not in use. The only 3 things that remains plugged in are the Fridge, Stove, and the alarm clock. The Television, sound system, game consoles, all that is on a power bar so its easy to just unplug the power bar. The laptop, computer, microwave, toaster, all that stuff can be left unplugged when I'm not using them. I even do it for the washer and dryer. It is only inconvencing yourself like 3 seconds max, and after a while you get used to it.

    I heard someone once say that your electronic devices still use 80% of their power consumption if plugged in, even while not in use. I think that number might be bogus, but I do believe that they still use power, even when not used.

    Point is, you can save alot of money by unplugging.

    How much? Really people get bent over SUVs but how many of those Prius owners have two or more big HDTVs, multiple game consoles, routers, PCs, DVRs, Home NAS servers, and goodness knows what else sucking down watts 24/7 often doing nothing at all?

    True but how much power do all the cell towers use? I am not anti tech but the explosion of tech we have has got to be running up our power bills.

    Thats a very amusing question, because a typical setup of 3G equipment draws about 3 KW, yet you're asking how much the tower itself draws, which is of course zero. The equipment draw at a site varies based on auxiliary gear, power level, multiple sites on multiple towers, multiple antennas on multiple gear, etc. Suffice it to say a cell site draws enough power to keep warm in the winter, but its not much compared to a steel mill or a retail establishment. The local power company is generally unimpressed in urban and suburban areas, although in rural areas the towers tend to be in the middle of nowhere resulting in some logistical difficulty, although the power required is no major thing. Local power companies do not install new substations just for a cellsite, for example, on the other hand when colocating in a building they will require a dedicated circuit or two, maybe a tiny subpanel, probably a separately billing power meter.

    On the other hand, the FAA requires substantial tower lighting, you're looking at about 1.5 KW of lighting on a big tower. See link to a typical supplier, note that light requires TWO 700 watt bulbs, pretty impressive. Then again a couple hundred watt light bulb is probably what you'd need to light up a couple hundred feet of street, it just makes sense.

    So, yes you could reduce the power used by the equipment. From 3KW to 3W to fit the pie in the sky 1:1000 ratio, probably not. Even if you could magically reduce the equipment power draw to zero, by using magic pixie dust and space alien technology, tower lighting requirements alone mean you'll never be able to reduce the total site power draw below about %33 of what is currently used.

    and thats before you get into discussions about aluminum towers, what with aluminum being "liquid electricity".

    Modern transceivers can work on low power too. Amateur radio QRP (low power) enthusiasts have achieved communication at startingly low power levels: "In the spring of 1994, Bob Moody and Bill Brown, WB8ELK shattered this 10-meter record by successfully using only 0.720 microwatts over a 1500-mile path for over 2 billion miles per watt" quoted from "ARRL's Low Power Communication: The Art and Science of Qrp"

    Don't computers only use a watt or two to sleep?

    200+ when booting?

    Waking from hibernate would then be worth over 2-hours of sleep (vs waking from sleep), and waking from shutdown even longer.

    Not at all. But a lot of GREEN folks are at the same time really into tech and really like to bash people that drive SUVs. I do not own an SUV or even a pickup truck. I really want a pickup truck but frankly only the Ford Ranger is close to what I think of as a small truck and I don't need a big truck. Just point out that waste is everywhere and having a house full of power sucking tech but a small car isn't all that green.
    BTW I too have to many gadgets sucking power. I started to buy power strips to power down some of my devices when I am not using then to save power.

With your bare hands?!?
