Abstract :
In the last few years, several gigabit-class wireless communication standards have reached commercial status, these are mainly driven by the higher demand of fast data transfer in multimedia applications (e.g. wireless HDMI, video streaming, etc.) At the same time, the number of portable devices has been increasing drastically; in the coming decade, the adoption of gigabit-class wireless communication in these portable devices will become a standard. In order to meet this demand, the electronic industry has to address the limitations of power consumption and form factor in the present solutions. Let us define gigabit class as physical layer data rate to be greater than 1Gb/s; while portability as the battery capacity limited to 25W-hour lithium polymer battery at 3.75V (similar to the Apple iPad) or about 1000mA-hour at 3.75V for a typical cellular phone. These devices offer different classes of multi-media experience, however, are both very popular among consumers. The key question is: how to be energy efficient in data-rate/power consumption for the Gb/s+device? For practical wireless application, the range needs to be at least a size of a room. In this special evening session, we have assembled a group of industrial experts in gigabit wireless communication to speak about their respective technology; and their views on how these standards can achieve lowest power AND highest data rate simultaneously. These standards include WirelessHD, Wireless Gigabit Alliance (802.11ad), 802.11ac and a proprietary short range radio. In addition, after 4 individual presentations, a panel discussion will be held to provide everyone in the session an opportunity to ask questions to these experts.
