Mobile Communications - GSM (Les caractéristiques de l ... Un slot accueille un élément de signal radioélectrique appelé burst. A chaque time slot, on associe un nombre connu par la station de base (BS) et le mobile (MS). Le numérotage des slots est cyclique de durée 3,5 heures. Gsm for-dummies - SlideShare Logical channels will be introduced in the next lesson.The time divisions in TDMA are known as Time Slots. Time Slots A frequency is divided up into 8 time slots, numbered 0 to 7. Time Slots On a side note, also remember that GSM carrier frequencies are separated by 200kHz and that GSM operates in duplex.
