You may have come across a standard wireless mouse before. No Bluetooth. Uses radio frequency (RF) technology. Older models operate at a frequency of 27 MHz. Their range is very short. About 6 feet or 2 meters is enough. The signal is weak. It falls off easily.
Newer models use the 2.4 GHz RF frequency. These are better. The range extends to 33 feet or 10 meters. The transfer speed is faster. There are fewer distractions. But there’s a problem. Using multiple RF mice in a room can cause crosstalk. The receiver picks up the wrong mouse. This is very confusing. You move your hand. The cursor moves from the laptop to the desktop.
Pairing and multichannel solve this problem. Separate the signals. Each mouse only communicates with its specific receiver.
USB receiver problems
Connect the RF receiver to the USB port. It’s very simple. Other peripherals cannot be used. Requires a mouse. A keyboard can also be included. that’s it.
There are different models of portable laptops. Equipped with a compact receiver. It can be stored in a place inside the mouse. I hide it there when I’m not using it. You are unlikely to lose your dongle.
“Pairing and transmission technology is specific to each manufacturer and device.”
Why you should buy a package
If you need both a wireless RF mouse and a keyboard, buy them together. Do not buy separately. The pairing technology is the manufacturer’s own. Equipment is important. If purchased separately, you may need two receivers. One is for the mouse. One is for the keyboard. Uses two USB ports. It’s chaos.
The current standard is 2.4 GHz. Provides speed and range. The 27 MHz standard is an old standard. It’s very slow. The range is short.
Which one do you need? 27 MHz might work if you sit close to your computer. However, the risk of interference is high. The use of several devices in the room can cause noise. The receiver gets confused. This is frustrating.
It is safer to choose a 2.4GHz RF mouse. The range will be longer. It’s faster. Less sensitive to interference. But you still need to pair it correctly. Otherwise, there will be crosstalk problems.
Buy a bundle. Save USB ports. Reduces headaches. This ensures that the mouse and keyboard work together. This technology is unique. It is not universal. Brands cannot be easily combined.
The market has moved to 2.4 GHz. 27 MHz mice are on the decline. they are very slow. they are limited. The new standard is faster. The range will be longer. Better.
However, pairing is important. Without the right combination, confusion ensues. The cursor moves automatically. This is very annoying.
This is how a wireless mouse works. They use radio waves. They need receivers. Must be paired. If you ignore this, your experience will be terrible.
The technique is simple. However, the implementation is different. You need to check the specifications. Look for 2.4GHz. Find the pairing function. Avoid using older 27 MHz models unless absolutely necessary. they are outdated. they are limited
