A computer usually has two input devices: a keyboard and a mouse. Over the years computer mice have evolved from ball based mice to optical ones and usually a cable that connects them to the computer. Mice have now more freedom as ever, losing the cable connection to the computer. By doing that, a system needed to be used to transmit the movement of the mouse to the computer. Among the technological solutions, Bluetooth stands out as a good wireless solution.
As a wireless standard, Bluetooth has an operational range of 10 m. It’s not much by any standards, but Bluetooth computer mice don’t go anywhere far from the computer. You might wonder what’s that special about Bluetooth that it’s a choice for mice. Bluetooth uses a free, unlicensed radio frequency band - 2.4 GHz ISM (Industrial, Scientific and Medical) short range band. You can even have your computer in an enclosed space and it wouldn’t matter as data transmitted over a Bluetooth transmission can go through physical objects. A Bluetooth connection is based on a master – slave configuration. In the Bluetooth computer mice case, the USB receiver that is placed in a USB port on the host computer is the slave and the mouse is the mater device.
It’s like this because the mouse transmits the information regarding the movement to the USB receiver. A Bluetooth computer mouse can be a good choice as many modern computers and laptops have integrated Bluetooth receivers and thus you can eliminate the USB receiver. In this way you can improve further the ergonomics on your desk.
Now that the technical part is in place and we have a rough idea about how Bluetooth works, we can focus more on the mouse part. It can come in a great variety of shape and sizes. Still some features are common as a Bluetooth transmitter, a battery bay, buttons and an optical laser tracking system. Some mice have programmable buttons, touch sensitive shells or scroll wheels/balls. It’s more comfortable to work with a Bluetooth mice because you don’t have to worry about cables anymore. The only thing that will catch your attention, beside its design, is the need to change the batteries from time to time.
