Description
Book SynopsisWireless Multimedia: A Handbook to the IEEE 802.15.3 Standard clarifies the IEEE 802.15.3 standard for individuals who are implementing compliant devices and shows how the standard can be used to develop wireless multimedia applications. The 802.15.3 standard addresses an untapped market that does beyond 802.11 and Bluetooth wireless technologies. The standard addresses the consumer need for low-cost, high data-rate, ad-hoc wireless connections. Some of these applications include: wireless keyboards and printers, personal video and digital cameras, cordless telephones and intercoms, digital audio players and headphones, gaming (including interactive gaming, multiplayer consoles, handheld multiplayer gaming, digital music, video, and image uploads to handheld games), home theater system and stereo system components, video conferencing, and more! Navigating through the IEEE 802.15.3 standard to find the required information can be a difficult task for anyone who has not spent a co
