| dc.description.abstract | ÖZET Bu tez, Baz İstasyonu (BTS) verilerini kullanarak Mobil ağlarda konum tahminini raporlamaktadır. İşlenen veriler sahadan TA (Timing Advance), RSRP (Reference Signal Received Power) ve RSRQ (Reference Signal Received Quality) ölçümleri olarak toplanmıştır. Ölçümlere karşılık gelen Global Konumlandırma Sistemi (GPS) verileri de toplanmıştır. Lokasyon tahminleri gerçek lokasyonla (GPS) karşılaştırılmıştır. Anahtar Kelimeler: Baz istasyonu, GPS, mobil ağlar, makine öğrenmesi, RSRP, RSRQ, timing advance (TA). ABSTRACT This thesis reports the location estimation on Mobile networks using Base Station (BTS) data. Processed data have been collected from the field as TA (Timing Advance), RSRP (Reference Signal Received Power), and RSRQ (Reference Signal Received Quality) measurements. We also gathered the corresponding Global Positioning System (GPS) to the measurements. Location estimation results compared to the actual location. Keywords: Base station, GPS, mobile networks, machine learning, RSRP, RSRQ, timing advance (TA).
