a. The average mobile user has 500 minutes of use per month; 90% of traffic occurs during work days. There are 20 week days per month. Assuming that in a given day, 10% of traffic occurs during the busy hour (BH), determine the traffic per subscriber per BH. b. During a busy hour, 1400 calls were offered to a group of trunks and 14 calls were lost. The average call duration has 3 minutes. Find Traffic offered, Traffic carried, Grade of Service (GOS) and the total duration of period of congestion. 7. What is the height to width ratio that gives the highest performance in case implementing Multiple Input Multiple Output (MIMO) using Planar Arrays?
