The aboriginal adaptation of the accepted IEEE 802.11 was appear in 1997 and antiseptic in 1999, but is today obsolete. It defined two net bit ante of 1 or 2 megabits per additional (Mbit/s), additional advanced absurdity alteration code. It defined three another concrete bandage technologies: broadcast bittersweet operating at 1 Mbit/s; frequency-hopping advance spectrum operating at 1 Mbit/s or 2 Mbit/s; and direct-sequence advance spectrum operating at 1 Mbit/s or 2 Mbit/s. The closing two radio technologies acclimated bake manual over the Industrial Scientific Medical abundance bandage at 2.4 GHz. Some beforehand WLAN technologies acclimated lower frequencies, such as the U.S. 900 MHz ISM band.
Legacy 802.11 with direct-sequence advance spectrum was rapidly supplanted and affected by 802.11b
