A transmitter, a receiver, and a method for extending a coverage in a local area wireless communication network are provided. A group forming unit may form a transmission group together with peripheral devices that enable a local area communication. A distributing unit may distribute, to the peripheral devices, data to be transmitted to a target receiver. A communication unit may transmit the distributed data to the peripheral devices through a frequency band used for the local area communication, and may transmit the distributed data to a reception group, to which the target receiver belongs, using a cooperative Multiple-Input Multiple-Output (MIMO) scheme with the peripheral devices.
