New technologies have long and firmly entered our lives. What used to seem like a miracle today is everyday life. Technology does not stand still, technical devices are actively evolving. Such a familiar and simple, it would seem, device, like a computer mouse, has also undergone significant changes.
Having appeared in the early 60s of the last century, this type of manipulator has become much more convenient, faster and more accurate. The technologies that are used in their work have changed. Today, there is already a large selection of wireless mice on the market, while a few years ago they didn’t even dream about it. There are several types of them, and in order not to make a mistake in choosing, you need to get a little familiar with their features, pluses and minuses.. , , – . , , , , – , .
The disadvantage of this transmission method is the need to use the manipulator in the redistribution of line of sight from the receiver. An excellent example of the use of such technology is the A4Tech G7-200NX-1 wireless mouse . This is an inexpensive, but at the same time reliable instance.
The most common way to transmit information from wireless manipulators is to connect via Bluetooth or a radio channel. Both of these methods have both advantages and disadvantages. Usually Bluetooth is used in laptops - there is a built-in module. This does not mean that you cannot install such a manipulator on a PC, you just have to buy the corresponding port. This method of connection provides high reliability of the connection within the acceptable distance.
Nevertheless, for stationary computers, radio mice are more often used. Such manipulators require a USB adapter.
There are radio transmitters operating at two frequencies: 2.4 GHz and 27 MHz. Higher frequencies are more expensive, but provide greater range. True, interference may interfere - many devices operate at this frequency. A wireless mouse with a frequency of 27 MHz imposes certain restrictions on the communication range, but near the receiver it works stably.Today, a wireless computer mouse is developed that uses Wi-Fi. This type of transmission provides the largest range - within network coverage. But there is a drawback - this method of transmitting information is subject to interference.
The wireless mouse may have batteries or batteries as a power source. Modern models can work on one set of batteries for up to 150 days with uninterrupted use. If you do not want to change batteries three to four times a year, buy batteries. You just need to charge them from time to time.
