Thus the sender may then have to resend all data starting with sequence number 2,000. The air controller requested that he resend his message, and he confirmed the hijacking. The transmitter then need only resend the blocks in error rather than the whole page. The nodes resend packets using the lowest range as the route selection criteria. Special receiver stations then decode the narrow-band signals and resend the data via Wi-Fi. This is important because SMBus does not provide any other resend signaling.
