802.11- 820.**

Answer 1

Hey,
I suggest that you at least spend some effort to provide a complete question, is this a why,what,where,does???

Otherwise you won't be receiving answers..

Answer 2

The IEEE 802.11 specification is a WLAN standard that defines a set of specifications for physical layers (PHYs) and a medium access control (MAC) layer. On the high-rate side, the 802.11b spec defines a set of re-quirements for a new PHY as an ex-tension to the legacy direct sequence spread spectrum (DSSS) PHY.

The upcoming IEEE 802.11e is an extension of the 802.11 WLAN standard for provisioning of QoS. This diploma thesis evaluates the problem of QoS support in 802.11e in coexistence scenarios. As long as a set of 802.11e-stations operates without any other competing stations in the area, QoS can be guaranteed by a central coordinator, using polling techniques. However, in the situation of overlapping sets of 802.11e-stations (OQBSS), all stations support priorities between different data streams, but cannot guarantee any QoS, because of the uncoordinated access to the common radio channel.

The number 802 was simply the next free number IEEE could assign, though "802" is sometimes associated with the date the first meeting was held - February 1980.

Answer 4

If you need someone else to do your homework, at least take the time to post the question from the book in full.
