First Claim
1. A method of operating a wireless network comprising at least two user equipments, each comprising a transmitter and a receiver, the method comprising:
- sending a beacon frame by a master user equipment at a transmit channel derivable from a user code, said beacon frame comprising a network code;
transmitting information data at a data channel obtained by an algorithm using said user code and said network code;
receiving said beacon frame by another user equipment;
extracting said network code from said beacon frame and calculating said data channel from said user code and said network code for receiving said transmitted information data.

Abstract
A method and device for operating a wireless network comprising at least two user equipments, each comprising a transmitter and a receiver. A beacon frame is sent by a master user equipment at a transmit channel derivable from a user code. The beacon frame comprises a network code. Any user equipment may calculate a data channel by an algorithm using the user code and the network code. The user equipment may be an active user, which is permitted to send data over said data channel, or a passive user equipment, which only receives transmitted data at said data channel. Several active users may transmit simultaneously. Such active users are entered on a list at the beacon frame and is designated each a transmit channel. A passive user may become an active user, for example by pushing a button, whereupon the passive user is entered on the list of active user and at the same time takes over the task to send the beacon frame, i.e. becomes a master user.
