maximum wireless transfer rate‚ at one-tenth of the cost‚ usually within a range of 10 meters [5]. In fact‚ GiFi is a wireless transmission system which is ten times faster than Wi-Fi and it is expected a revolution networking in offices and homes by implementing high-speed wireless environments. It utilizes a 5mm square chip and a 1mm wide antenna burning less than 2milli watts of power to transmit data wirelessly over short distances‚ much like Bluetooth [6]. Abstract—GiFi is a wireless transmission
