Task Group 4: Low Rate WPAN
IEEE 802.15.4-2003 (Low Rate WPAN) deals with low data rate but very long battery life (months or even years) and very low complexity. The standard defines both the physical (Layer 1) and data-link (Layer 2) layers of the OSI model. The first edition of the 802.15.4 standard was released in May 2003. Several standardized and proprietary networks (or mesh) layer protocols run over 802.15.4-based networks, including IEEE 802.15.5, ZigBee, 6LoWPAN, WirelessHART, and ISA100.11a.

Famous quotes containing the words task, group and/or rate:
“... the task of youth is not only its own salvation but the salvation of those against whom it rebels, but in that case there must be something vital to rebel against and if the elderly stiffly refuse to put up a vigorous front of their own, it leaves the entire situation in a mist.”
—Jane Addams (18601935)
“The government of the United States at present is a foster-child of the special interests. It is not allowed to have a voice of its own. It is told at every move, Dont do that, You will interfere with our prosperity. And when we ask: where is our prosperity lodged? a certain group of gentlemen say, With us.”
—Woodrow Wilson (18561924)
“As a novelist, I cannot occupy myself with characters, or at any rate central ones, who lack panache, in one or another sense, who would be incapable of a major action or a major passion, or who have not a touch of the ambiguity, the ultimate unaccountability, the enlarging mistiness of persons in history. History, as more austerely I now know it, is not romantic. But I am.”
—Elizabeth Bowen (18991973)
