Wireless data communication system having improved data communication efficiency

A method for communicating data comprising the steps of:

• selecting in a second processor a first number of data bits from a data stream from a first processor, which first number of data bits are to be transmitted but have not yet been transmitted,
• transmitting from a second processor a first data packet having the selected first number of data bits,
• re-transmitting from a second processor the first data packet, if a signal acknowledging receipt of the first data packet is not received from a receiving party,
• repeating the re-transmission step a predetermined number of times if the receiving party continues not to receive the first data packet,
• informing the first processor when the receiving party fails to receive the first data packet after a predetermined re-transmission number is reached,
• selecting a second number of data bits that has been divided by a number of data packets, received from the first processor, from the data stream that has not yet been transmitted, and
• transmitting a second data packet that includes the selected second number of data, if a predetermined re-transmission number has been reached.

A data communication system for transmitting data, comprising:

• a first processor and
• a second processor in communication with the first processor, the second processor receiving data transferred from the first processor, the second processor having:
• a data packet generator that outputs a first data packet having the received data,
• a transmitter coupled to the data packet generator for transmitting the first data packets to a receiving party,
• an acknowledgement circuit that monitors acknowledgement signals from the receiving party and generates an output if an acknowledgment signal is received,
• a counter coupled to the acknowledgement circuit and the transmitter for counting the number of transmissions of data packets without receiving an acknowledgement signal from the receiving party, the counter generating a noisy environment signal if a pre-determined number of transmissions have occurred without receiving an acknowledgment signal and
• a reduced data packet generator coupled to the transmitter and the counter for generating a second data packet having a reduced number of data bits, if the counter generates the noisy environment signal.

A data communication system comprising:

• a first processor,
• a second processor coupled to the first processor, wherein the first processor communicates transmission data and a data packet number to the second processor, the second processor selects a number of data bits from un-transmitted data based on the data packet number and transmits a data packet that includes the selected data bits, wherein if the transmitted data bits are not received by a receiving party, the second processor retransmits a data packet with the same data bits, wherein:
• if the first processor receives from the second processor a signal indicating that the number of re-transmissions has reached a predetermined re-transmission number, then the first processor provides a new data packet number that is different from the previous data packet number;
• and
• the second processor sends to the first processor said signal indicating that the number of re-transmissions has reached the predetermined re-transmission number, and then the second processor selects a number of data bits based on the new data packet number from the un-transmitted data, the new data packet number being provided from the first processor,
• wherein an antenna is coupled to the second processor to transmit the data packet signals and to receive communication signals.
