The most widespread WLAN standard, IEEE 802.11, in the DCF mode, uses channelized bandwidth, where MAC operation takes place within a given channel. Same channel re-use makes it possible to enhance coverage efficiency. Multi-channel protocols can be exploited in WLANs in order to make use of additional bandwidth, or to decouple different transmissions, hoping to reduce collisions in distributed access modes.

Abstract
The most widespread WLAN standard, IEEE 802.11, in the DCF mode, uses channelized bandwidth, where MAC operation takes place within a given channel. Same channel re-use makes it possible to enhance coverage efficiency. Multi-channel protocols can be exploited in WLANs in order to make use of additional bandwidth, or to decouple different transmissions, hoping to reduce collisions in distributed access modes.File allegati a questo prodotto
