A signal relaying apparatus includes a plurality of devices for relaying
signals to and from distant nodes in a wireless communication network. At
least one of the devices is an antenna; the devices may also include one
or more cables. The devices are connectable to a transmitter and a
receiver in the apparatus. The receiver receives a signal from one node
through one of the devices; the transmitter transmits the same signal to
another node through another of the devices. The signal may also be
amplified or buffered before being transmitted. Because the signal is
transmitted and received through different devices, the transmission of a
signal packet can begin while the packet is still being received, thereby
shortening the delay from reception to transmission, as compared with the
delay in conventional apparatus that both receives and transmits the
packet through a single antenna.
