The disclosure relates to a method for configuring an WLAN (Wireless Local Area Network) access point adapted to use at least one operational frequency channel to transmit or receive data when the access point is in an operational mode. The configuring includes checking an availability of at least one restricted frequency channel, a use of the restricted frequency channel being restricted by the availability, choosing the operational frequency channel from a set of frequency channels according to the checked availability, a first configuring comprising a first checking of restricted frequency channels belonging to a first proper sub-set of the set being performed before entering into the operational mode. At least one second checking of at least one restricted frequency channel of the set, that has not been checked as available, is performed after the first configuring.

Configuring method and corresponding communication network device, system, computer readable program product and computer readable storage medium

A configuration method of a first access point of a network is disclosed, which comprises a configuration of the first access point as belonging to a low power set and able to transmit at a power level lower than a first value on at least one low power channel; a transmission of an indication that the first access point belongs to the low power set and a selection of a low power channel for transmission among at least one low power channel on which the reception power of a signal transmitted by the neighboring access points is less than a second power level.

Method for configuration of a wireless network

The present invention relates to a compact slot antenna formed, in a multilayer substrate comprising, in order, at least one first conductive layer, a first dielectric layer, a second conductive layer, a second dielectric layer and a third conductive layer, of a first slot-line realized in the second conductive layer, said first slot-line being connected to the supply of the antenna, of a second and a third slot-lines realized respectively in the first and in the third conductive layers, the second and third slot-lines each being delimited by two conductive strips of which a first extremity, supply side, is interconnected by a via passing through a window realized in the second conductive layer and a second extremity connected to the second conductive layer, both conductive strips on the side of the second extremity being, either in open circuit, or in short circuit, the electrical length of the first, second and third slot-lines being a function of the wavelength at the operating frequency of the antenna.

Compact slot antenna

The invention relates to method for configuring a first wireless network that includes at least one access point. In order to optimize the configuration of the first wireless network, the method comprises a step of configuring at least one parameter of the at least one access point of the first wireless network on the basis of at least a portion of the linking balance of a second wireless network including at least two nodes, the nodes being positioned in a predetermined physical space.

Method for configuring a wireless network

In order to increase the transmission speed in a wireless network comprising at least a node, the method comprises the following steps:

Contention for wireless access using two types of channels

The invention proposes a repeater designed for indoor transmissions. The useful frequency band is split into two frequency bands and the repeater amplifies the signals from one of the bands and translates them to the other band. The transposition of frequency bands results in preventing creating significant interference effects on the signal to be amplified. A management circuit is used to address, at lower cost, interference problems between the bands.
