eli5: Why do wireless peripherals come with their own bluetooth dongle? Why can’t my PC use one dongle to connect to multiple devices?
In: Technology
The dongles don’t USE Bluetooth, or they wouldn’t need the dongle. It, as far as I am aware, is a radio wireless receiver that also serves to decode the signal transmitted from the mouse. As to why each mouse needs their own, one may use slightly different frequencies or something, but if I’m not mistaken it mostly has to do with preventing interference. It wouldn’t make sense for me to be able to plug in a mouse, and suddenly my buddy with the same brand can control it. Plus, it’s a lot cheaper on computer manufacturers to pass on the costs of the receivers onto the mice companies, considering the user may not even use a wireless one.
