Embodiment Construction

[0061] Referring to Fig. 1, the network system 100 of the preferred embodiment of the present invention will be described in detail.

[0062] Fig. 1 shows a network system 100 comprising a first computer terminal 101, a second computer terminal 102, a third computer terminal 103 and a fourth computer terminal 104, each computer terminal having a processor (not shown). The computer terminals 101 to 104 are wirelessly interconnected via a first channel 105 , a second channel 106 , a third channel 107 and a fourth channel 108 . Via any of the channels 105-108, any of the computer terminals 101-104 may wirelessly transmit data to any other of the computer terminals 101-104. Each of the computer terminals 101 to 104 is adapted to communicate in accordance with IEEE 802.11, and the network system 100 forms a WLAN. The communication may also be centralized and one of the terminals may be a so-called access point, however this will be described for a general decentralized situation. ...

Abstract

A method of operating a network node of a network, a network node, a network system, a computer-readable medium, and a program element A method (300) of operating a network node (101 - 104) of a network system (100), comprising the steps of generating (305) a signal to be transmitted, selecting (310) one of a plurality of communication channels (105 - 108) of the network system (100) for transmitting the signal, and, in case that the selected channel (105 - 108) is not ready for transmitting the signal, selecting (345) another one of the plurality of communication channels (105 - 108) for transmitting the signal.

Description

field of invention [0001] The present invention relates to the network field. In particular, the invention relates to a method for operating a network node in a network, a network node, a network system, a computer readable medium and a program element. technical background [0002] A WLAN ("Wireless Local Area Network") is a local network consisting of a number of network nodes that communicate wirelessly. A WLAN can be implemented using frames conforming to the IEEE 802.11 standard (see LAN MAN Standards Committee of the IEEE Computer Society, Wireless LAN Medium Access Control (MAN) and Physical Layer (PHY) specifications, IEEE Standard 802.11, 1999 Edition). [0003] IEEE 802.11 is a global standard for wireless local area networks (WLANs) that continues to improve in response to increasing user demands and applications for higher throughput and quality of service (QoS). [0004] In WLAN, two different network nodes can exchange data according to the implemented commun...
