With the continuous advancement of mobile devices in daily life scenarios and wireless data transfer applications, there is an inevitable need for a universal, flexible, high bandwidth, direct wireless communication interface between devices.

Until now these user requirements has been met by solutions using the limited capabilities of worldwide available WLAN networks, which are based on the IEEE 802.11 standard. The Wi-Fi connections are basically resource distribution networks following a star topology, which are unsuitable for maintaining a number of parallel, high-speed, point-to-point connection, due to the experienced propagation properties and license-free usage habits the operate mainly in

the 2.4 and 5 GHz ISM bands.

The WiGig trade association has began promoting a novel, millimeter-wave, multi-gigabit wireless standard in 2009, aimed to replace the short-range, high-speed wired connections like USB, HDMI and PCI-E. The standard uses a 2 GHz channel bandwidth within the available 7 Ghz wide spectrum in the license free 60 GHz band, with applying active beam-forming as well.

The standardization process went through in close cooperation with the Wi-Fi Alliance and highly aligned with the existing IEEE 802.11 standard, so the IEEE adapted it overwriting their own ongoing 802.11ad amendment. As part of the 802.11 the Wi-Fi compatibility enables the operation of new devices in an integrated, multi-band fashion on existing networks.

This thesis amongst the presentation and the evaluation of the WiGig system also includes a description of a function package created in the Matlab simulation environment for the simulation of the physical layer. Also competing technologies, existing instruments, uses cases and opportunities

offered by the system are mentioned as well. The detailed description of the standard emphasis on physical layer of the single-carrier (SC) and the low power (Low-Power SC) single-carrier modulation. The given software package is created to perform both generation and demodulation of SC and Low-Power

SC packets, using single carrier modulation techniques according to the IEEE 802.11-2012 standard, furthermore to perform and test frame detection and synchronization in real life scenarios where noise, timing error and frequency offset may occur.
