Problems solved by technology

But if the presence of legacy equipment is found in the extended channel, the master station must select other communication channels
[0008] The disadvantage of communicating in this way is that it is rather inflexible and can lead to underutilization of effective communication channels

Embodiment Construction

[0019] Figure 1 shows a general overview of a communication system according to a set of IEEE Std. 802.11 specifications. The basic elements in this network structure are called Basic Service Sets (BSS). BSS n It is defined as a group of stations (wireless nodes) located in a substantially restricted physical area, in which each station (STA) can theoretically communicate with every other STA (assuming no physical or other communication obstacles. environment). There are two basic wireless network design structures defined, ad hoc and infrastructure.

[0020] The IEEE 802.11 wireless network or communication system based on infrastructure consists of one or more BSSs, and the BSSs are interconnected through other networks such as IEEE 802.3 wired Ethernet. The infrastructure for this connection is called a distribution system (DS). In this infrastructure, each BSS n There must be exactly one wireless station connected to the DS. This station provides information from the...

Abstract

The invention relates to a wireless communication system comprising a master station, a first additional station, and a second additional station, whereby the master station is operable to communicate with the first and second additional stations in a first high-speed mode utilizing a first channel and at least a second channel and in a second low-speed mode utilizing either the first channel or the second channel, the first additional station is operable to communicate in the first mode utilizing the first channel and at least the second channel, and the second additional station is arranged to communicate in the second mode utilizing either the first channel or the second channel, characterized in that master station is arranged to define a plurality of first time slots on the first channel and a plurality of second timeslots on the second channel for communication in the first mode, and a plurality of third time slots on the first channel and a plurality of fourth time slots on the second channel for communication in the second mode.

Description

technical field [0001] The invention relates to a wireless communication system as defined in the preamble of claim 1 . [0002] The present invention also relates to a station used in a wireless communication system and a communication method in the wireless communication system. Background technique [0003] Such a wireless communication system is disclosed in IEEE802.11a Standard Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specification, 1999: High-Speed ​​Physical Layer in 5 GHz Band, IEEE, NY, 1999. Wireless communication systems compliant with this standard operate in the 5GHz license-free ISM band and can support raw data rates ranging from 6 to 54 Mbit / sec using Orthogonal Frequency Division Multiplexing (OFDM) technology. IEEE Standard 802.11b discloses a similar communication system operating in the 2.4GHz ISM band. To meet the needs of delay-limited applications, a new specification p802.11e has been proposed to incorporate data link layer ...
