ABSTRACT:
In a carrier sense multiple-access (CSMA) network, such as a wireless network or a LAN, a transceiver which initiates a transmission to a recipient transceiver in the same medium sends out, prefatory to a bulk of data, a field representative of the length of the data, and another field symbolic of the rate at which the data is to be sent. Non-participant transceivers in the medium receive the data length field and the data rate field, and calculate a length of time they must inhibit themselves to avoid a data collision with the transmitting transceiver, while the participants come to a common agreement at which they can send and receive data.
