Encryption: | A security method that uses a specific algorithm to alter the data |
| transmitted, thus prevent others from knowing the information |
| transmitted. |
ESS: | ESS stands for “Extended Service Set”. More than one BSS is |
| configured to become Extended Service Set. LAN mobile users can |
| roam between different BSSs in an ESS. |
ESSID: | The unique identifier that identifies the ESS. In infrastructure |
| association, the stations use the same ESSID as AP’s to get |
| connected. |
Ethernet: | A popular local area data communications network, originally |
| developed by Xerox Corp., that accepts transmission from |
| computers and terminals. Ethernet operates on a 10/100 Mbps |
| base transmission rate, using a shielded coaxial cable or over |
| shielded twisted pair telephone wire. |
Fragmentation: | When transmitting a packet over a network medium, sometimes |
| the packet is broken into several segments, if the size of packet |
| exceeds that allowed by the network medium. |

Threshold: | The Fragmentation Threshold defines the number of bytes used for |
| the fragmentation boundary for directed messages. The purpose of |
| “Fragmentation Threshold” is to increase the transfer reliability thru |
| cutting a MAC Service Data Unit (MSDU) into several MAC Protocol |
| Data Units (MPDU) in smaller size. The RF transmission can not |
| allow to transmit too big frame size due to the heavy interference |
| caused by the big size of transmission frame. But if the frame size is |
| too small, it will create the overhead during the transmission. |
Gateway: | A device that interconnects networks with different, incompatible |
| communication protocols. |
