Modulation techniques

Characteristics of IEEE 802.11n and 802.11ac deliver same performance for one quarter the cost of wired systems

Understanding modulation and coding schemes

Multiplexing is a technique where multiple signals are combined into a single or shared medium. Multiplexing/demultiplexing is referred to as mux/demux. Courtesy: Daniel E. Capano, Diversified Technical Services

MIMO and spatial multiplexing

Multipath is a phenomenon that occurs when an RF signal travels over many different paths between the transmitter and receiver, arriving at different times at the receiver. Courtesy: Daniel E. Capano, Diversified Technical Services

Propagation revisited: Wireless multipath

A centralized controller architecture regulates the operation of the WLAN and usually takes the form of a hardware device that either is wired to the APs at the network edge, or uses a wireless system to provide local connection to clients on one frequenc
