A method for load balancing in a network access system with a number of network access devices (110, 120, 130) each of which is connected to a network and allows network access to communication devices connectable to said network access devices (110, 120, 130), wherein at least a subset of said number of network access devices (110, 120, 130) are wirelessly interconnected, comprising the steps of - organizing said number of network access devices (110, 120, 130) into at least one group of network access devices, wherein each group is associated with a selected transmission channel, so that network access devices of different groups do not interfere with each other, and further wherein said organization is controlled by a centralized network server of the network, - sending a request from a communication device to a first network access device of said number of network access devices (110, 120, 130) for initiating a data flow between said communication device and a destination node connected to said network, - determining a congestion state of the connection between the first network access device and said network, and - if congestion of the connection between the first network access device and said network is detected, - selecting a second network access device from said number of network access devices (110, 120, 130) from members of the same group depending on the quality of the respective wireless connection with the first network access device, and - establishing a data flow between the communication device and the destination node, such that data originating from the communication device is transmitted from the first network access device via the second network access device to the network and data received from the network is transmitted from the second network access device via the first network access device to the communication device. - organizing said number of network access devices (110, 120, 130) into at least one group of network access devices, wherein each group is associated with a selected transmission channel, so that network access devices of different groups do not interfere with each other, and further wherein said organization is controlled by a centralized network server of the network, - sending a request from a communication device to a first network access device of said number of network access devices (110, 120, 130) for initiating a data flow between said communication device and a destination node connected to said network, - determining a congestion state of the connection between the first network access device and said network, and - if congestion of the connection between the first network access device and said network is detected, - selecting a second network access device from said number of network access devices (110, 120, 130) from members of the same group depending on the quality of the respective wireless connection with the first network access device, and - establishing a data flow between the communication device and the destination node, such that data originating from the communication device is transmitted from the first network access device via the second network access device to the network and data received from the network is transmitted from the second network access device via the first network access device to the communication device.
