| ISM Band: | The FCC and their counterparts outside of the U.S. have set aside | 
| 
 | bandwidth for unlicensed use in the ISM (Industrial, Scientific and | 
| 
 | Medical) band. Spectrum in the vicinity of 2.4GHz, in particular, is | 
| 
 | being made available worldwide. | 
| MAC Address: | Media Access Control Address is a unique hex number assigned | 
| 
 | by the manufacturer to any Ethernet networking device, such | 
| 
 | as a network adapter, that allows the network to identify it at the | 
| 
 | hardware level. | 
| Multicasting: | Sending data to a group of nodes instead of a single destination. | 
| Multiple Bridge: | One of the additional AP operating modes offered by 54Mbps | 
| 
 | Access Point, which allows a group of APs that consists of two or | 
| 
 | more APs to connect two or more Ethernet networks or Ethernet | 
| 
 | enabled clients together. The way that multiple bridge setups is | 
| 
 | based on the topology of  | 
| Node: | A network junction or connection point, typically a computer or | 
| 
 | workstation. | 
| Packet: | A unit of data routed between an origin and a destination in a | 
| 
 | network. | 
| PLCP: | Physical layer convergence protocol | 
| PPDU: | PLCP protocol data unit |
