METHOD FOR DETECTING DEGRADATION OF LTE REPEATER

摘要

PURPOSE: A deterioration sensing method of an LTE(Long Term Evolution) repeater is provided to sense the deterioration of the LTE repeater by detecting levels of an input end and an output end of a signal transmission path. CONSTITUTION: A level for a gain operated in an output end of a main system is measured. The deterioration of a repeater is sensed according to a difference between the measured levels and an initial value of the set normal state. A deterioration determination value corresponding to the difference between the levels is calculated. The calculated deterioration determination value and the set reference value are compared. When the deterioration determination value is over the reference value, the repeater determines a deterioration state. [Reference numerals] (1) A: Input detector power value; (2) C: Output detector power value; (3) Starting time is based on a time when there is no user; (4) Reason for setting -70 as a reference: Reference value according to machine standard minimum input power; (AA) Algorithm ends if less than -70dBm, due to -65dBm(Example); (B1) Store TX input DET value "A"; (B2) Store TX output DET value "C"; (B3) Store machine Gain value "C-A"; (CC) Yes(Operate after 24 hours); (DD) Current TX input DET value "A" >= - 70; (EE) Stored "A" value ? Current "A" value <= 5; (FF) Stored Gain value ? Current Gain value "C-A" >= 5; (GG) Yes(Increase count 1); (HH) Generate inspection requirement; (II) No(Set as count =0)
