Patent ID: 7515606

Claim:
An ultra wide band (UWB)-based wireless bridge, comprising: a physical layer processing means for encoding a first physical layer signal transmitted from a serial bus device connected through wire into a first link layer data and decoding a second link layer data into a second physical layer signal; a protocol converting means for separating the first link layer data transmitted from the physical layer processing means into a first isochronous data and a first asynchronous data, performing path establishment and synchronization, multiplexing the first isochronous data and the first asynchronous data into a first protocol adaptation layer (PAL) data of an IEEE 802.15.3 media access control (MAC) service data unit (MSDU) frame, and converting the first PAL data into a first MAC data of an IEEE 802.15.3 MAC protocol data unit (MPDU) frame, converting a second MAC data into a second PAL data, separating the second PAL data into a second isochronous data and a second asynchronous data, performing path establishment and synchronization, and multiplexing the second isochronous data and the second asynchronous data into the second link layer data; a UWB signal transceiving means for converting the first MAC data transmitted from the protocol converting means into first IJWB signals, transmitting the first LIWB signals through an antenna, and converting second UWB signals received through the antenna into the second MAC data; and a controlling means for controlling and managing the physical layer processing means, the protocol converting means, and the UWB signal transceiving means, wherein the protocol converting means includes a MAC transmitting means for converting the first PAL data into the first MAC data, the MAC transmitting means to transmit at least one of command data or the first asynchronous data based on a Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) method in a selective contention access (CA) period established in a piconet superframe, and to transmit at least one of the command data, management data, the first asynchronous data or real-time isochronous data based on a Time Division Multiple Access (TDMA) method in a basic channel time allocation (CTA) period.
