expected to be completed by the end of 2019 [1]. However, 60 GHz band is completely different than 2.4 GHz and 5 GHz bands regarding the propagation of radio signals. IEEE 802.11ad is defined at 60 GHz bands (microwave WiFi), low power, but has very high performance regarding maximum bitrates (up to almost 7 Gbit/s). But such bitrates are available only in very short ranges, such as 1-10 m, within a single room or office. Although IEEE 802.11ac and 802.11ad both provide much higher data throughputs than their predecessors, such as IEEE 802.11n/a/g/b, they have much different potential uses. On the one hand, IEEE 802.11ac is a kind of an evolution of previous WLAN standards toward higher bitrates, offering the possibility of the "wireless office" to compete directly with gigabit wired systems while having wireless connection flexibility. On the other hand, IEEE 802.11ad provides ad-hoc short-range connectivity in support of extremely high data rates. However, in all WiFi standards the theoretical maximum bitrates that can be achieved on MAC layer are not possible due to the WiFi radio access scheme, and hence the expected throughput (achievable aggregate bitrate) is around 70% of the theoretical maximum, as shown in Table 5.4. In practice, all given bitrates can be much lower at longer distances between AP and wireless stations (e.g. lap-top, smartphones with WiFi) due to lower signal to noise ratio which results in a different modulation and coding scheme that carries fewer bits per symbol in the radio interface, thus resulting in lower bitrates than the maximum possible throughput with a given WiFi standard. Besides the standardization of different WiFi amendments on the physical layer, there are many amendments on protocol layer 2, which are created for different purposes, such as application support (e.g. 802.11p/z/aa), network convergence (e.g. 802.11u), net- work management (e.g. 802.11k/v), QoS (e.g. 802.11e), security (e.g. 802.11i), etc. In general, WiFi network architecture is based on APs, which work on
