Abstract
Official abstract text for this publication.
A test system for determining a total radiated power of an antenna over the air comprises a measuring device and the base station. The measuring device is embodied to establish a communications connection to the base station to be tested over the air and to initiate and use over the air a function for fixing a present beam-lock function of the base station to be tested. The measuring device is further embodied to identify and measure a maximum effective isotropic radiated power, and to determine the total radiated power from previously known antenna characteristics and the measured maximum effective isotropic radiated power.
First claim
Opening claim text (preview).
The invention claimed is: 1. A test system for determining over the air a total radiated power of an antenna of a base station to be tested, comprising: a measuring device, the base station to be tested, wherein the measuring device is embodied to establish a communications connection to the base station to be tested over the air, to initiate a function for fixing a present beam-lock function of the base station to be tested over the air, by means of the function for fixing the present beam-lock function of the base station to be tested, to fix the beam-lock function of the base station to be tested, to measure a maximum effective isotropic radiated power, and to determine the total radiated power of the antenna of the base station to be tested from previously known antenna characteristics of the antenna of the base station to be tested and the measured maximum effective isotropic radiated power, wherein the test system is embodied to prevent a communication of further mobile devices with the base station to be tested during the measurement of the maximum effective isotropic radiated power. 2. The test system of claim 1 , wherein the measuring device is embodied to simulate a mobile device. 3. The test system of claim 1 , wherein the base station to be tested is an active antenna base station. 4. The test system of claim 1 , wherein a measurement signal transmitted from the base station to be tested occupies only a proportion of a base-station signal in the time domain and/or in the frequency domain. 5. The test system of claim 1 , wherein a test command is protected and/or restricted. 6. The test system of claim 5 , wherein the base station to be tested is embodied to respond to the test command only after confirmation by a network operator. 7. The test system of claim 5 , wherein the base station to be tested is embodied to respond to the test command only within a predefined time window. 8. The test system of claim 5 , wherein the test command is the function for fixing a present beam-lock function of the base station to be tested, and/or a command for the exclusion of further mobile devices from a communication with the base station. 9. The test system of claim 1 , wherein the base station to be tested is embodied to transmit with a maximum amplification during the measurement of the maximum effective isotropic radiated power. 10. A test method for determining over the air a total radiated power of an antenna of a base station to be tested, with the following steps: establishing a communications connection between a measuring device and the base station to be tested over the air, initiation of a function for fixing a present beam-lock function of the base station to be tested over the air by the measuring device, fixing of the present beam-lock function of the base station to be tested, by means of the function for fixing the present beam-lock function of the base station to be tested by the measuring device, measurement of a maximum effective isotropic radiated power by the measuring device, determination of the total radiated power of the antenna of the base station to be tested from previously known antenna characteristics of the antenna of the base station to be tested and the measured maximum effective isotropic radiated power, by the measuring device, and preventing a communication of further mobile devices with the base station to be tested during the measurement of the maximum effective isotropic radiated power.
