LAN

technologies, transfer protocols, data transfer speeds and wiring.

IEEE 802.11

IEEE

802.11 is a standard for wireless LANs operating in the 2.4 GHz band. In so-called

Infrastructure mode

terminals can be connected to a base station (

Access point

) or they

can connect with each other spontaneously (

Ad-hoc mode

).

IGMP
Internet Group Management Protocol
IGMP is an Internet

Protocol

that enables an Internet computer to inform neighbouring

routers that it is a member of a multicast group. With multicasting, a computer can send
content on the Internet to several other computers that have registered an interest in
the first computer's content. Multicasting can, for example, be used for multimedia pro-
grams for media streaming to recipients that have set up multicast group membership.

Infrastructure mode
Infrastructure mode is a way of operating wireless local networks (

WLANs

) in which an

Access point

handles the data traffic. Network components cannot establish a direct

connection with each other as is the case in

Ad-hoc mode

.
