Nano Receivers vs. Bluetooth
Some Bluetooth receivers are nano receivers, but not all nano receivers use Bluetooth technology. Bluetooth receivers employ 2.4 GHz band radio communication and are capable of linking multiple devices together, which is why they are called “unifying devices.” Devices linked together over Bluetooth form a piconet, so such receivers are sometimes called USB pico receivers. Some non-Bluetooth nano wireless receivers operate on the same frequency; however, they only work with specific devices, such as the keyboard or mouse that they came packaged with.
USB vs. Nano Receivers
Before nano wireless receivers came out, USB receivers were about the size of a common USB flash drive. They protruded out of the side of a laptop’s USB port, posing an inconvenience. Users had to plug in and remove them after each use, increasing the odds of the receiver getting lost or damaged. Nano wireless receivers, on the other hand, are designed to be left in the laptop’s port at all times. They are often so small that they are almost unnoticeable. Since they fit snugly into the side of the computer, you can pack your laptop in its case without worrying about the receiver or USB port getting damaged.
