A method for wireless communication between a base station and a number of devices is provided, with the devices in each case having a limited energy supply. To establish a connection, the base station sends a sequence of synchronization signals on at least one of its communication channels. The devices in each case listen on their parameterized or unparameterized communication channel within a listening period, which is repeated with a repetition frequency that can be set. Outside the listening period, the device in question is set to an energy-saving mode. The length of the listening period, the repetition frequency and the energy consumption in the energy saving mode are synchronized with each other in such a way that the energy consumption up to the connection setup averaged over time does not exceed the energy consumption during normal operation of the device.
