A communication system is configurable to operate in either a transparent mode or a data streaming mode. In the transparent mode data is transferred to a data requesting component from a data source using a request-response protocol. In the data streaming mode a second data transfer component is configured to obtain data from the data source component via a third data link, and to transfer the data to a first data transfer component via a second data link, which has a relatively higher latency, without using the request-response protocol. The first data transfer component is configured to store the transferred data and to transfer the stored data to the data requesting component via the first data link upon receiving a request for the stored data from the data requesting component.

Data communication system with multiple data links and operating modes

Communication apparatus comprises a first transceiver unit (A) and a signal processing device () configured to receive a signal from the first transceiver unit and to produce a signal for transmission by the first transceiver unit. A cable (A) connects the first transceiver unit to the signal processing device. The first transceiver unit comprises a housing; a first pair of transducers (T,R) located at, or adjacent, a first end of the housing, and a second set of transducers (T,R) located at, or adjacent, an opposite end of the housing.

Communication apparatus

A communication system) comprises a first set () of transducers and a second set () of transducers. The system further comprises a first signal processing device () configured to produce a signal for transmission by at least some of the transducers in the first set to at least some of the transducers in the second set, and a second signal processing device () configured to process signals received from at least some of the transducers in the second set in order to select a best said signal that is used for further processing. The first set of transducers comprises a first subset () comprising at least one said transducer, and a second subset () comprising at least one said transducer. Transducers in the first subset transmit on a first channel and transducers in the second subset transmit on a second channel having a different frequency.
