Wireless communication system and method for the same
First Claim
1. A wireless communication method for a computer and a plurality of input devices with different categories, each of the input devices comprising a transmitter and the computer comprising a receiver for receiving a wireless signal from each transmitter, the method comprising the steps of:
- assigning each input devices with a predetermined communication channel according to the category thereof, wherein the input devices with the same category are assigned with the same communication channel;
each of the input device sending a plurality cycles of periodic input signals in a first time slot when the input device is operated;
the receiver receiving the input signals for each input device in a cycle with a second time slot shorter than the first time slot, wherein the receiver receives the input signals of the input devices in a predetermined sequence.

Abstract
In a computer with a plurality of wireless input devices, a communication system and a method identify the input signal from the plurality of input devices. The computer includes a receiver to receive RF signal from the wireless input devices. The wireless input devices of different categories will use different communication channels. For example, mice use the first communication channel, keyboards use the second communication channel. The input signal is prefixed with an ID code comprising a category field and a serial field. The same input signal will be consecutively sent in many cycles in a first time slot and the receiver will receive the input signal in a second time slot shorter than the first time slot. The receiver will sequentially receive a plurality of inputs signal in a plurality of receiving cycles, and discriminate the input signal through the ID code.
