High-Speed Wireless Personal Area Networks: an Application of UWB Technologies
7 High-Speed Wireless Personal Area Networks: An Application of UWB Technologies H. K. Lau The Open University of Hong Kong Hong Kong 1. Introduction Recently, a large number of wireless networks are being developed and deployed in the market. According to the communication range, wireless networks can be classified into wireless wide area networks (WWANs), wireless metropolitan area networks (WMANs), wireless local area networks (WLANs), wireless personal area networks (WPANs), and wireless body area networks (WBANs). With the advances in wireless technologies, latest generation of WPANs can provide a data rate of hundreds (or even thousands) of Mbps at a distance of less than 10 meters. Ultra-wideband (UWB) is an emerging technology that offers distinct advantages, e.g. high bandwidth and small communication ranges, for WPAN applications (Park & Rappaport, 2007; Chong et al., 2006; Fontana, 2004; Intel, 2004; Porcino & Hirt, 2003). One of the ‘killer’ applications of high-speed WPAN is wireless video area network (WVAN) that offers wireless transmission of high-definition videos (several Gbps) within a small communication distance (Singh et al., 2008; Wirelesshd 2009; Whdi 2009). This chapter provides a comprehensive summary on the latest development and standardization progress of high-speed WPANs. There are seven sections in this chapter. The first section describes the background of WPANs and introduces the IEEE networking standards for WPAN. The second section discusses characteristics of UWB signals and explains why they are particularly suitable for high-speed WPAN applications. The third section discusses technical challenges and standardization issues. The fourth section reports on the latest development of high-speed WPANs. -

Wigig and IEEE 802.11Ad for Multi-Gigabyte-Per-Second WPAN
WiGig and IEEE 802.11ad For Multi-Gigabyte-Per-Second WPAN and WLAN SaiShankar N, Debashis Dash, Hassan El Madi, and Guru Gopalakrishnan Tensorcom Inc., 5900 Pasteur Court, Carlsbad, CA 92008 Abstract: The Wireless Gigabit Alliance (WiGig) and IEEE 802.11ad are developing a multigigabit wireless personal and local area network (WPAN/WLAN) specification in the 60 GHz millimeter wave band. Chipset manufacturers, original equipment manufacturers (OEMs), and telecom companies are also assisting in this development. 60 GHz millimeter wave transmission will scale the speed of WLANs and WPANs to 6.75 Gbit/s over distances less than 10 meters. This technology is the first of its kind and will eliminate the need for cable around personal computers, docking stations, and other consumer electronic devices. High-definition multimedia interface (HDMI), display port, USB 3.0, and peripheral component interconnect express (PCIe) 3.0 cables will all be eliminated. Fast downloads and uploads, wireless sync, and multi-gigabit-per-second WLANs will be possible over shorter distances. 60 GHz millimeter wave supports fast session transfer (FST) protocol, which makes it backward compatible with 5 GHz or 2.4 GHz WLAN so that end users experience the same range as in today’s WLANs. IEEE 802.11ad specifies the physical (PHY) sublayer and medium access control (MAC) sublayer of the protocol stack. The MAC protocol is based on time-division multiple access (TDMA), and the PHY layer uses single carrier (SC) and orthogonal frequency division multiplexing (OFDM) to simultaneously enable low-power, high-performance applications. Keywords: 60 GHz communications; IEEE standards; WiGig; 802.11ad; contention based access protocol; scheduled protocol; Beamforming; power save 1 Introduction There is a huge amount of unlicensed spectrum available worldwide in the 60 GHz band. -

The Workflow of WLAN Module Integration As we see the wireless revolution enters its next phase of deployment, we also see a large shift toward putting wireless local area network (WLAN / IEEE802.11) capabilities on a wide variety of non-traditional products like thermostats, coffee makers, and even toothbrushes. These consumer items could be controlled via an application from a smart phone or other devices connected to the internet. One advantage of using connected devices like smart phones is the applications can be developed very quickly and the end customer is presented with an integrated experience with their wireless devices. To date, this has been done with music players, GPS devices, cameras, video cameras, televisions, video games, etc. Another application driving this is the Internet of Things (IOT), where even more industrial and consumer devices are connected wirelessly. -
