FTP
File Transfer Protocol. A standard protocol for sending files between computers over a TCP/IP network and
the Internet.
Fragment Threshold
Frame Size larger than this will be divided into smaller fragment. If there are interferences in your area, lower
this value can improve the performance. If there are not, keep this parameter at higher value. The default size
is 2346. You can try 1500, 1000, or 500 when there are interference around your network.
Full Duplex
The ability of a networking device to receive and transmit data simultaneously. In wireless environment, this is
usually done with 2 or more radios doing load balancing.
Gateway
In the global Internet network, the gateways are core routers that connect networks in different IP subnet
together. In a LAN environment with an IP sharing router, the gateway is the router. In an office environment,
gateway typically is a multi-function device that integrates NAT, firewall, bandwidth management, and other
security functions.
Hotspot
A place where you can access Wi-Fi service. The term hotspot has two meanings in wireless deployment.
One is the wireless infrastructure deployment, the other is the Internet access billing system. In a hotspot
system, a service provider typically need an authentication and account system for billing purposes, and a
wireless AP network to provide access for customers.
IGMP Snooping
Internet Group Management Protocol (IGMP) is a Layer 3 protocol to report IP multicast memberships to
neighboring multicast switches and routers. IGMP snooping is a feature that allows an Ethernet switch to
"listen in" on the IGMP conversation between hosts and routers. A switch support IGMP snooping has the
possibility to avoid multicast traffic being treated as broadcast traffic; therefore, reducing the overall traffic on
the network.
Infrastructure Mode
A wireless network that is built around one or more access points to provide wireless clients access to wired
LAN / Internet service. The opposite of Infrastructure mode is Ad-hoc mode.
