Access Point Quick Setup 4-15
Enabling the RTS Threshold causes redundant network overhead that could
negatively affect the throughput performance instead of providing a remedy.
4.4.4 Fragmentation Threshold
A Fragmentation Threshold is the maximum data fragment size (between 256 and 2346 bytes) that can be
sent in the wireless network before the ZyAIR will fragment the packet into smaller data frames.
A large Fragmentation Threshold is recommended for networks not prone to interference while you should
set a smaller threshold for busy networks or networks that are prone to interference.
If the
Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set, then the
RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented
before they reach
RTS/CTS size.
4.4.5 ESS ID
An Extended Service Set (ESS) is a group of access points or wireless gateways connected to a wired LAN
on the same subnet. An ESS ID uniquely identifies each set. All access points or wireless gateways and their
associated wireless stations in the same set must have the same ESSID.
4.4.6 WEP Encryption
WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network. WEP
encryption scrambles the data transmitted between the wireless stations and the access points to keep network
communications private. It encrypts unicast communications in a network. Both the wireless stations and the
access points must use the same WEP key for data encryption and decryption.
