Abstract

Methods and systems for interfacing between broadband wireless communication systems and Local Area Network (LAN) systems includes a repeater station placed at a location that receives sufficient signal strength from a broadband wireless service provider. LAN devices interface with the broadband wireless service provider through the repeater station. The LAN devices are able to operate within the operating range of the repeater station. The repeater station includes a protocol converter that interfaces between a first protocol associated with the broadband wireless service provider, and one or more protocols associated with the devices. For example, and without limitation, the protocol converter converts between a first protocol associated with a Wide Area Network (WAN) service provider, such as a cellular telephone protocol, and one or more LAN protocols associated with the one or more devices. The one or more devices optionally include one or more wireless devices.
