In with new technologies have shown the potential for major energy reductions: ◇ 10-20% reduction in energy use for base stations through new energy management software for our wireless network equipment; ◇ 47% reduction in energy use and 67% reduction in land use for our core network equipment through our new platform structure; ◇ 47% reduction in energy use for base stations through bi density wireless carrier technology improvements; and ◇ 12-20% of energy saving with intelligent carrier shut-off technology in our base stations which closely monitors call volume to control power and shut off carrier.
