Abstract
A method of transmitting and receiving a two-way serial digital signal in a wireless network is disclosed. The method utilizes a baseband processor to modulate user data along a 2.45 GHZ RF signal. The method permits the transmission and reception of data along the network between any two units without the need for assistance from other units to pass the data along the network. The method utilizes a protocol wherein a first network unit sends an acknowledgment packet to a second unit in response to receiving a data packet from the second network unit. The second unit will attempt to resend the data packet up to five times until it receives the acknowledgment packet from the first unit. Since the reception of data packets is considered more important than the transmission of data packets, each network unit will remain in a receive mode for a pre-defined period of time until it is determined that no data packets have been received at which time each network unit will inquire whether any packets are waiting to be re-transmitted or transmitted for a first time. If such packets are ready for transmission, the network unit will enter a transmit subroutine whereby a waiting packet will be transmitted.
