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.
Fragmentation
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.
HEX:
Hexadecimal, HEX, consists of numbers from 0 – 9 and letters from
A – F.
IEEE:
The Institute of Electrical and Electronics Engineers, which is
the largest technical professional society that promotes the
development and application of electrotechnology and allied
sciences for the benefit of humanity, the advancement of the
profession. The IEEE fosters the development of standards that
often become national and international standards.
Infrastructure:
An infrastructure network is a wireless network or other small
network in which the wireless network devices are made a part of
the network through the Access Point which connects them to the
rest of the network.
