  • Apparatus and method for planning a wireless network
    Publication number: 20090185502
    Abstract: An apparatus and method for planning a wireless network is provided. An apparatus for planning a wireless network includes a parameter input unit for receiving parameter information, and outputting the parameter information, a Rise over Thermal (RoT) calculator for calculating an RoT using the parameter information, and outputting the RoT, a first uplink performance prediction index determiner for determining a Modulation and Coding Scheme (MCS) level using the RoT, and outputting determined MCS level information, a maximum achievable Carrier to Interference and Noise Ratio (CINR) calculator for calculating a maximum achievable CINR of the determined MCS level using the determined MCS level information, and outputting a calculated maximum achievable CINR, and a second uplink performance prediction index determiner for determining at least one among a mobile station (MS) transmission power, a data rate, and an uplink CINR using the determined MCS level information.
