Abstract

The embodiments herein relate to a method performed by a testing device for enabling testing of a communication node. The testing device measures a test parameter associated with RF characteristics of the communication node when it is located at a test location during a first condition. The communication node is configured with a node setting during the measurement in the first condition. The testing device measures the test parameter associated with the RF characteristics of the communication node when it is located at the test location during a second condition. The communication node is configured with the same node setting in the second condition as in the first condition. The testing device checks whether a result parameter associated with the test parameter measured during the first and second condition fulfills a requirement.

measuring a test parameter associated with radio frequency (RF) characteristics of the communication node when the communication node is located at a test location during a first condition, thereby producing a first measurement value for the test parameter;
measuring the test parameter associated with the RF characteristics of the communication node when the communication node is located at the test location during a second condition, thereby producing a second measurement value for the test parameter;
obtaining a result value using the first and second measurement values, wherein the result value is a function of at least the first and second measurement values; and
determining whether the result value fulfills a requirement.

2. The method according to claim 1 , further comprising:
measuring the test parameter associated with the RF characteristics of the communication node when the communication node is at a reference location during the first condition, thereby producing a third measurement value for test parameter, wherein
obtaining the result value comprises obtaining the result value using the first measurement value, the second measurement value, and the third measurement value, wherein the result value is a function of at the first, second, and third measurement values.

3. The method according to claim 2 , further comprising:
determining whether the third measurement value fulfills the requirement.

4. The method according to claim 2 , wherein obtaining the result value comprises:
calculating a difference between the first and second measurement values, and
summing the calculated difference and the third measurement value.

5. The method according to claim 1 , wherein the result value is a vector that comprises the first and second measurement values.

6. The method according to claim 1 , further comprising:
when the result parameter does not fulfil the requirement, verifying that the communication node is not capable of operating during the second condition.

7. The method according to claim 1 , further comprising
determining whether the test parameter measured during the first condition fulfills a requirement; and
as a result of determining that the test parameter measured during the first condition does not fulfil the requirement, verifying that the communication node is not capable of operating during the first condition.

8. The method according to claim 1 , wherein the test parameter is at least one of: Equivalent Isotropic Radiated Power, Equivalent Isotropic Sensitivity, Timing Alignment Error, and frequency stability.

9. The method according to claim 1 , wherein the communication node is an Active Antenna System base station.
