| طرق اختبار التشكيل البيني المنفعلة لأنظمة الهوائيات الصفيفية في أنظمة الاتصالات المتنقلة |
تحدد التوصية ITU-T K.149 طرق قياس مستوى التشكيل البيني المنفعل لأنظمة الهوائيات الصفيفية في أنظمة الاتصالات المتنقلة، بما في ذلك معدات الاختبار وإجراءات الاختبار.
وتغطي هذه التوصية مديات التردد التالية، ولكنها لا تقتصر عليها: نطاقات تشغيل LTE 700 وAPT 700 وLTE 800 وCellular 850 وE-GSM 900 وDCS 1800 وPCS 1900 وAWS 1700/2100 وUMTS 2100 وLTE 2600. |
