Abstract
A method and system implementations thereof include receiving data from a passive optical network (PON) outside a building; wirelessly transmitting the received PON data to inside the building; and applying the received PON data to a network inside the building. The data received outside the building is from an optical line termination (OLT). The PON data wireless transmitted inside the building may be applied to an optical line terminal (ONT) inside the building. Alternatively, the wirelessly received PON data may be converted to Ethernet format and applied to a user interface and/or a gateway interface all inside the building. The wireless transmission of PON data may be via a first transceiver mounted on a surface outside the building and a second transceiver mounted on a surface inside the building. The surface may be a corridor, a window, a door, a walls and a façade.
