ABSTRACT
Area Network (WPAN), including Bluetooth, Ultra Wideband and ZigBee ◾ Learn the special features of Worldwide Interoperability for Microwave Access (WiMAX) ◾ Understand the evolution of radio technologies in the development of cellular networks
Figure 9.1 provides a complete overview of all the available wireless technology. The figure illustrates for each standard both the data rate in megabits per second and the range in meters. For example, 802.11n [1] supports data rates up to 600 Mbps within a short range of about 200 meters outdoors. 802.11ac is a standard currently under development which will provide high throughput WLAN operation at up to 1.73 Gbps. In January of 2012 Broadcom demonstrated a chip operating at 1.3 Gbps over the unlicensed 5 GHz band. In addition, 802.11ad will define highperformance wireless implementations for widely used computer peripherals and display interfaces over the unlicensed 60 GHz frequency band at speeds of up to 7 Gbps. The wide variety in standards is a reflection of the desire to satisfy the various needs of different applications.
