An operating method for a location estimation apparatus communicating with an access point (AP) in a wireless communication system according to an embodiment of the present invention comprises the steps of: receiving, from a second AP, a first received signal strength indicator (RSSI) signal having been measured at a first AP, and generating a first RSSI vector corresponding to the first RSSI signal; calculating a path loss exponent, using the distance between the first AP and the second AP and the first RSSI vector, and generating a second RSSI vector of each of multiple sub-areas divided from an entire area, using the path loss exponent; and generating a radio map of the entire area, using the first RSSI vector and the second RSSI vector.

Location estimation method and apparatus using access point in wireless communication system

A variable valve lift apparatus may include a variable valve lift housing, a master piston which is slidably disposed in the variable valve lift housing and contacts a cam, a slave piston which is slidably disposed in the variable valve lift housing, defines an oil chamber with the master piston therebetween, and opens a valve connected to the slave piston according to reciprocative motion of the master piston, and a lift control portion which supplies oil to the oil chamber or exhausts oil in the oil chamber selectively to control a relative distance between the master piston and the slave piston.
