Master-Slave
In synchronous data communications systems, all components of the link should operate
using the same clock. The Master unit provides the clock and the Slave unit reconstructs it
from the data received from the master unit.
Total Link Delay
In order to improve performance the 2.048Mbps Wireless Modem uses an Automatic
Retransmission Queuing (ARQ) mechanism that enables to detect errors in the received data
and to request retransmission of that data. The ARQ mechanism breaks the data into
fragments (called buffers) and adds a Cyclical Redundancy Check (CRC) code, which
enables detection of errors in the received fragment. A header providing unique identification
as well as Acknowledge/Not Acknowledge response is attached to each fragment.
