If the Wi-Fi is a format well defined by the Wi-Fi alliance and that allows data transfer via radio frequencies; other formats of wireless connections are available, but much less popular. Among them, we should mention the Multi-Gigabit Wireless managed by Wireless Gigabit alliance. This format, whose specifications have just been frozen, is using a frequency bandwidth around 60 GHz and claims to be able to reach 7 Gbits/s (almost 1 GB/s). However, it remains unclear how far such transfer speed can be achieved, and what is the effective range of this wireless network; most likely way below the current range of the Wi-Fi.While waiting for its potential mass adoption for IT network, it is mostly being developed to allow wireless communication and data transfer between multimedia devices, such as a TV set and peripherals.
