Abstract:

A wireless hard disk drive is disclosed. The wireless hard disk drive includes a microprocessor, a Synchronous Dynamic Random Access Memory (SDRAM), a hard disk, a wireless chip, an antenna, and an Ethernet communication unit. The microprocessor has an SDRAM controller, a wireless chip controller and an Ethernet controller. The SDRAM is interfaced with the SDRAM controller of the microprocessor, and stores operational data. The hard disk is interfaced with a memory controller of the microprocessor, and stores data. The wireless chip is interfaced with the wireless chip controller of the microprocessor, and is configured to modulate data 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. The antenna is connected to a transmitter and a receiver. The Ethernet communication unit is interfaced with the Ethernet controller, and allows the data to be stored and the data stored on the hard disk to be accessed. 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.
