Patent Searching and Data


Title:
WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/115121
Kind Code:
A1
Abstract:
The disclosed wireless communication system conducts wireless communication between one receiver (1) and a plurality of electric tools (2). Each electric tool (2) is given a different registry number and a corresponding designated transmission interval (T), and when data is transmitted from the electric tool (2), the receiver (1), which receives the data, transmits a signal to indicate receipt of said data to the electric tool (2). Each electric tool (2) is configured in such a way that the electric tool determines that data transmission is complete upon receipt of the signal to indicate receipt of data, but determines that data transmission is incomplete if the electric tool does not receive said signal, and retransmits the data after waiting for the transmission interval (T). Different transmission intervals (T) are set per registry number so that the electric tools (2) can each complete data transmission within a designated period of time.
