Wireless communication is being developed in the last years day by day, there are several standards that talks about it. We are going to go through the IEEE standard 802.11 which talks about wireless LAN Medium Access Control (MAC) and Physical Layer
The ZigBee specification is a standard for low-power consuming wireless devices. The ZigBee protocol stack has a layered structure containing four distinct layers of which the two lowest layers are defined by the IEEE 802.15.4 standard. Building on this base the ZigBee
Wireless data networks is a growing business and the demand for higher capacity is increasing rapidly. There exist a number of standards for wireless LANs (WLANs) and the most popular one is the IEEE 802.11 family. This thesis investigates the capacity of
