Cellphones make Wi-Fi hotspots

摘要

They say many hands make light work. Now many cellphones make fast Wi-Fi.rnIf a wireless network is lacking, most cellphones can be "tethered" to a laptop and used as a modem, but connection speed is limited.rnSo a team of researchers at Microsoft Research India in Bangalore and the University of California, Santa Barbara, has designed a system called Cool-Tether, which allows groups of cellphones with Wi-Fi capabilities to pool their connections and create a high-speed wireless network for nearby computers.rnCool-Tether requires software to be installed on the computer and cellphones used in this way.
