    Abstract: A method and apparatus for managing a wireless local area network are disclosed. The network includes one or more wireless access points, each including a radio frequency assembly having a variable power output, and an antenna assembly for transmitting and receiving wireless signals. A microcontroller is included for sending a transmission characteristics signal to the wireless local area network. A network manager is included for receiving the transmission characteristics signal and selectively controlling the variable power output of the radio frequency assembly to a predetermined power level.

    Abstract: A method for controlling cell sizes (118a, ..., 118n) associated with respective access points (102a, ..., 102n), each having a receive sensitivity and an output power. The method includes changing the start of packet thresholds and/or clear channel assessment thresholds to vary the cell sizes (I 18a,...,118n) of the access points (102a, ..., 102n).

    Abstract translation: 一种用于控制与相应接入点（102a，...，102n）相关联的小区大小（118a，...，118n）的方法，每个接入点具有接收灵敏度和输出功率。 该方法包括改变分组阈值的开始和/或清除信道评估阈值以改变接入点（102a，...，102n）的小区大小（I 18a，...，118n）。

    Abstract: The present invention is directed to a system and method for sending and receiving Voice-over-Internet-Protocol over a wireless computer network utilizing a hybrid wireless voice-over-Internet-Protocol telephone. The invention utilizes a phone controller (302), a wireless handset (100), a base station (310) and at least one access point (304). The wireless handset is equipped with both a wireless personal area network transceiver and a wireless local area network transceiver. The base station (310) is equipped with a wireless personal area network transceiver and a network interface card. Voice-over-Internet-Protocol packets are routed to the phone controller (302) which forwards the packets to either the access point (304) for transmission to the wireless handset (100) over the wireless local area network (306,304,316), to the base station (310) for transmission to the wireless handset (100) over the personal area network (314), or to a server for transmission out of the local area network. The wireless personal area network can be based upon Bluetooth or IrDA
