REPEATER AND METHOD FOR OPERATING SUCH A REPEATER
First Claim
1. A telecommunications system, comprising:
- a master unit; and
remote units for communicating with mobile radio terminals and for communicating with the master unit, at least one of the remote units including a sensor and a control unit, the sensor being configured for detecting a parameter about a coverage environment, the control unit being configured for outputting a switching signal based on the parameter for causing the at least one of the remote units to switch between a passive operating state and an active operating state in which the at least one of the remote units transmits signals wirelessly at a higher power as compared to the passive operating state.

Abstract
A repeater capable of emitting as little electromagnetic radiation as possible is described. The repeater can transmit communication signals between a base station and a network terminal in a radio transmission network, such as a mobile radio network. The repeater can include a transmitter that can transmit the communication signals as a radio signal to the network terminal. The repeater can also include a sensor for detecting a switching signal and a control unit that can change the transmitter between a passive operating state and an active operating state based on the switching signal. The transmission power of the transmitter can be lower in the passive operating state than in the active operating state.

9. A distributed antenna system, comprising:
-
a master unit; remote units for communicating with mobile radio terminals and for communicating with the master unit, each of the remote units including a sensor configured for detecting whether a mobile radio terminal is present in a coverage environment for an associated remote unit or whether a light is in an “
on”
state in the coverage environment; anda control unit configured for outputting a switching signal based on the sensor detecting the mobile radio terminal in the coverage environment or the light being in the “
on”
state in the coverage environment, the switching signal being usable for causing the associated remote unit to switch from a passive operating state in which the associated remote unit normally operates to an active operating state in which the associated remote unit transmits signals wirelessly at a higher power as compared to the passive operating state. - View Dependent Claims (10, 11, 12, 13)

14. A method, comprising:
-
wirelessly transceiving signals in a coverage environment at a passive operating power level by a remote unit; detecting a change in a parameter in the coverage environment by a sensor in the remote unit; responsive to detecting the change in the parameter in the coverage environment, changing a power level of the remote unit to an active operating power level that is a higher power level than the passive operating power level; and wirelessly transceiving signals with one or more mobile radio terminals in the coverage environment at the active operating power level by the remote unit. - View Dependent Claims (15, 16, 17, 18, 19, 20)
