Interfacing a legacy data bus with a wideband wireless data resource utilizing an embedded bus controller
First Claim
1. A method of interfacing a legacy data bus to a wideband wireless data resource with a legacy interface having a bus controller module, the method comprising:
- wirelessly receiving data at the legacy interface via the wideband wireless data resource, from a wideband capable node, the data being intended for a legacy node, wherein the legacy node is a MIL-STD 1553 node;
converting the received data to a legacy format comprising at least one data word, wherein the legacy format is compliant with MIL-STD 1553;
transmitting the at least one data word on the legacy data bus, wherein the legacy data bus is a MIL-STD 1553 bus;
receiving a reply to the at least one data word on the legacy data bus; and
forwarding the reply via a wireless data communication link to a wideband capable node using the bus controller module in the legacy interface.

Abstract
Various methods and systems provide interfaces between legacy data buses such as MIL-STD 1553 buses and wideband wireless data links such as links compatible with IEEE 802.11 or IEEE 802.16e. One technique for interfacing a legacy bus to a wideband wireless data communication link involves providing a hybrid bus controller/remote interface unit as an interface between the two data communication architectures. In operation, the legacy interface suitably receives data intended for a legacy node from a wireless radio module that is compatible with a designated broadband wireless data communication protocol. The legacy data is converted in the legacy interface/remote interface unit to at least one legacy word having a legacy format for transmission on the legacy data bus. The legacy interface may be further configured to receive a reply message from the legacy component on the legacy data bus, and to forward a reply to the wireless radio module in a format that is compatible with the designated wireless data communication protocol.
