Abstract:
A method for transmitting wireless input data from a data entry device to a host system, comprising the steps of:(a) formulating input data to be provided from the data entry device to the host system in a form of a packet of N bytes, the packet including codes for identifying the data entry device and representing a data input generated by the data entry device, N being an integer greater than three; (b) dividing the N bytes of the packet into a series of data symbol, each data symbol being composed of two bits and having an identical data symbol duration; (c) converting each data symbol into a series of four chips, each chip having an equal chip duration and the sum of four chip durations being equal to one data symbol duration; (d) activating one chip among the series of four chips to thereby transmit the wireless input data from the data entry device to the host system.
