Wireless USB adapters allow computers to send and receive data through a wireless connection. They plug into the one of the USB ports and usually draw power from the host computer, eliminating the need for batteries or power cords. Most models have status lights indicating power supply and connection status. Many also have plug-and-play installation and are easily shared between computers.
These adapters are box-shaped and about the same size as PCI cards.
They are placed on a desk or flat surface and connect to the computer with a short USB cable.They usually have adjustable antennas for improving signal reception.
Encryption: Choose a wireless USB adapter with a secure encryption method to protect your files during transfer. Look for one that provides 64 to 128-bit Wired Equivalent Privacy (WEP) encryption to keep them from getting intercepted through the network. Range: Choose a wireless USB adapter that receives signals from a wide coverage area. Look for one with a range of about 300 feet indoors and 1,300 feet outdoors.
