WiMax, Metro-Fi More Energy Efficient Than 3G So says ABI Research, anyway... (old news - 08:16AM Tuesday Jan 16 2007) tags: wireless · hardware
According to ABI Research, "From a pure coverage perspective WiMAX is twice as energy-cost-effective and metro Wi-Fi is 50 times more energy-cost-effective than WCDMA. When data traffic is factored into the equation, WiMAX can accommodate 11 times today's average data consumption and still be more energy-cost-efficient compared to WCDMA or HSDPA." According to the group, there's a lot of power that will be chewed up by these services in the years to come; global mobile broadband energy use will rise from 42.8 billion kilowatt hours (KWh) in 2005 to 124.4 billion KWh in 2011.
I suspect this is on the base station end... Sure a WiMAX base station will cover a large area, and doesn't use a whole lot of power. Standard cells are 1-3 miles apart. The power consumption comes from having multiple sites. Also, do WiMAX phones/data cards use more power than cell phones ?
eg. AMPS uses a lot of power iDEN uses a lot of power (short battery life) CDMA (1x/EVDO) is more efficient (power control) GSM (TDMA) is more efficient yet (less cpu power usage than CDMA)
Re: let me know when I can get wimax everywhere I can 3G...
WiMax will most likely be the next global standard as opposed to the two standards we have today, which is GSM and CDMA because its open licensing scheme and ability to operate on pretty much any frequency you want to run it on.
