The coexistence in the normal wireless network of physical layer and the low rate of the physical layer of the rate

摘要

A system includes a first preamble generation module , and a second preamble generation module , and a packet generation module . The first preamble generation module to generate a first preamble . The first preamble includes a first training field for training a receiver operating at a first data rate (TF). The second preamble generation module , generates a second preamble . The second preamble includes a first 2TF for training the receiver operating at the second data rate . The second data rate different from the first data rate . Packet generation module , generates a packet . The packet , in response to the packet is transmitted at a first data rate , the first preamble after the second preamble is arranged , or , in response to the packet is transmitted at a second data rate , and the the second preamble is located after the preamble 1 .
