1. A method of operating a communication system comprising a number of devices suited for wireless communication, the method comprising:
- providing at least a number of infrastructure nodes and number of leaf nodes, the leaf nodes adapted to exchange messages with the infrastructure nodes, the infrastructure nodes being adapted to exchange messages with leaf nodes and infrastructure nodes; and
configuring a leaf node to associate with at least two infrastructure nodes and send a data packet to each of the two infrastructure nodes simultaneously via a first transmission, wherein each associated infrastructure node for the leaf node, if the first transmission is received, determines whether the leaf node is an associated leaf node and, if so, directs the data packet toward a destination.

Abstract
Methods and devices for operating a wireless network including redundant communication. Methods involving redundantly connected nodes are discussed including addressing methods and/or methods of creating groups for such redundant communication. The use of primary and secondary redundant connections is discussed. Also, devices for implementing such methods.

10. A method of operating a communication system comprising a number of devices suited for wireless communication, the method comprising:
-
providing at least a number of infrastructure nodes and number of leaf nodes, the leaf nodes adapted to exchange messages with the infrastructure nodes, the infrastructure nodes being adapted to exchange messages with leaf nodes and infrastructure nodes; and configuring a leaf node to associate with at least two infrastructure nodes and send a data packet as follows; in a first transmission, the leaf node sends the data packet to a first of the at least two infrastructure nodes by addressing the data packet to the first infrastructure node; in a second transmission, the leaf node sends the data packet to a second of the at least two infrastructure nodes by addressing the data packet to the second infrastructure node. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A communication system comprising at least a number of infrastructure nodes and number of leaf nodes, the leaf nodes adapted to exchange messages with the infrastructure nodes, the infrastructure nodes being adapted to exchange messages with leaf nodes and infrastructure nodes;
- wherein;
a leaf node associates with at least two infrastructure nodes; the leaf node sends a data packet to the two infrastructure nodes simultaneously via a first transmission; and each associated infrastructure node for the leaf node that receives the first transmission determines whether the leaf node is an associated leaf node and, if so, directs the data packet toward a destination. - View Dependent Claims (20, 21)

22. A communication system comprising at least a number of infrastructure nodes and number of leaf nodes, the leaf nodes adapted to exchange messages with the infrastructure nodes, the infrastructure nodes being adapted to exchange messages with leaf nodes and infrastructure nodes, wherein
a leaf node associates with at least two infrastructure nodes and sends a data packet as follows: -
in a first transmission, the leaf node sends the data packet to a first of the at least two infrastructure nodes by addressing the data packet to the first infrastructure node; in a second transmission, the leaf node sends the data packet to a second of the at least two infrastructure nodes by addressing the data packet to the second infrastructure node.
