Wireless hard disk drive

A wireless hard disk drive, comprising:

• a microprocessor configured to have a Synchronous Dynamic Random Access Memory (SDRAM) controller, a wireless chip controller and an Ethernet controller;
• an SDRAM interfaced with an SDRAM controller of the microprocessor, and configured to store operational data of the microprocessor;
• a hard disk interfaced with a memory controller of the microprocessor, and configured to store data;
• a wireless chip interfaced with a wireless chip controller of the microprocessor, and configured to modulate data, which are stored on the hard disk, into radio frequency signals and then transmit the radio frequency signals, and to demodulate received radio frequency signals into data and then transfer the data to the wireless chip of the wireless chip controller;
• an antenna connected to a transmitter and receiver, and configured to transmit radio frequency signals to the air and detect the radio frequency signals from the air;
• and
• an Ethernet communication unit interfaced with the Ethernet controller, and configured to allow the data to be stored on the hard disk and allow the data stored on the hard disk to be accessed via a network;
• wherein the elements are contained in a single portable housing, so that the wireless hard disk drive can have mobility, portability and wireless connectivity to a host device.
