摘要： When the communication channel is to be changed, a more optimal communication channel is determined by summing up the results of measuring communication states transmitted from individual wireless terminals A, B, and C and making a collective judgment. Weighting coefficients are set to the individual wireless terminals A, B, and C. Values indicating whether or not the respective communication states of the individual wireless terminals are optimal with channels ch1 to ch4 to be used for communication (which are, e.g., 1, 0, 1, 2 with the respective channels ch1, ch2, ch3, and ch4 for the wireless terminal A and larger as the communication states are less optimal) are multiplied by the weight coefficient (the value of 3). The resulting values are summed up on a per-channel basis and the most optimal communication channel (of which the summed value is lowest) is selected. As a result, wave interference with the other wireless terminal is reduced.

摘要： A packet synthesizing unit packetizes transmit data and thereby creates a transmit packet data, and more specifically, synthesizes the number of the transmit data indicated by a packet-length information from a packet length controlling unit into a transmit packet data. A frame synthesizing unit appends the packet-length information for transmission to a header of the transmit packet data to thereby create a transmit frame. A wireless transmit unit converts the transmit frame into a wireless transmit signal and wirelessly transmits the wireless transmit signal. In the wireless transmission, the packet length controlling unit controls the packet length of the transmit data according to a transmit rate in the wireless transmit unit. The packet length controlling unit reduces the packet length when the transmit rate is relatively high and extends the packet length when the transmit rate is relatively low. This improves the transmission efficiency and communication quality.

摘要： Provided is a network chip that controls issuance of interrupts based on the contents of the received packets. The network chip receives a data packet containing a type that indicates a realtime packet or a not-realtime packet, where the realtime packet needs consideration of delay time, and the not-realtime packet does not need consideration of delay time. The network chip obtains a type by analyzing the received packet. When the obtained type indicates a realtime packet, the network chip stores the received packet into a realtime reception packet buffer, and issues an interrupt to the CPU immediately; and when the obtained type indicates a not-realtime packet, it stores the received packet into a not-realtime reception packet buffer, and issues an interrupt to the CPU after a predetermined time period passes, or after the number of packets stored in the not-realtime reception packet buffer reaches a predetermined number.

摘要： In a case where it is determined that communication data indicates a first data attribute in a transmitter, that communication data is transmitted and an acknowledgement signal is requested to be sent back from a receiver. If the acknowledgement signal is not sent back, that communication data is retransmitted. In a case where it is determined that the communication data indicates a second data attribute in the transmitter, that communication data is transmitted and an acknowledgement signal is requested to be sent back according to an allowable number of retransmissions corresponding to the second data attribute. And that communication data is retransmitted in accordance with the allowable number of retransmissions and presence or absence of the acknowledgement signal sent back. The allowable number of retransmissions corresponding to the second data attribute is smaller than that corresponding to the first data attribute.
