The exponential grow of data traffic, sets stringent requirements for future generation networks. The study of the existing networks allows to understand important factors for the design of the future networks. Moreover , the LTE network is going to be part of the next generation infrastructure until new infrastructures have covered all areas. This paper studies the LTE network of an entire city in terms of users’ behavior and throughput. Based on the measurements in a real network can estimate the trend of users’ activity in one day (24 hours) and the peak number in terms of throughput. Finally, from the measurements the required capacity is calculated for a particular city and compare today’s needs with the needs at the future networks .
