An introduction to satellite networks and wireless technologies

Transport layer The transport layer performs host-to-host communications on either the same or different hosts and on either the local network or remote networks separated by routers. In order to create a new version, TGm combines the previous version of the standard and all published amendments.

It specified three alternative physical layer technologies: If it is an acceptance, the frame will contain information such an association ID and supported data rates.

Key architectural principles[ edit ] An early architectural document, RFCemphasizes architectural principles over layering. The payload or frame body field is variable in size, from 0 to bytes plus any overhead from security encapsulation, and contains information from higher layers.

The frame includes information required for association such as the association ID and supported data rates.

Internet protocol suite

It is also sometimes necessary for network address translator NAT traversal to consider the application payload. Four versions were developed: New versions of the IEEE November Main article: The next two bytes are reserved for the Duration ID field. It is an amendment that defines a new physical layer for Some frames may not have a payload.

The common structure of an IE is as follows: Currently used protocol version is zero. Please update this article to reflect recent events or newly available information. It also provides multi-homing support, in which a connection end can be represented by multiple IP addresses representing multiple physical interfacessuch that if one fails, the connection is not interrupted.

However communication within an independent basic service set IBSS network always set these bits to zero. This does not mean that the technical overlap of the channels recommends the non-use of overlapping channels.

Internet layer[ edit ] The internet layer has the responsibility of sending packets across potentially multiple networks.IEEE is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication in the MHz and, 5, and 60 GHz frequency bands.

They are the world's most widely used wireless computer networking standards, used in most home and office networks. The Internet protocol suite resulted from research and development conducted by the Defense Advanced Research Projects Agency in the late mi-centre.com initiating the pioneering ARPANET inDARPA started work on a number of other data transmission technologies.
