Mobile traffic forecasts 2010-2020 Total daily mobile traffic From 2010 to 2020, total daily mobile traffic in the representative Western European country will grow 67 times from 186 TB to 12540 TB. Total daily mobile traffic 2010 2015 2020 Representative Western European Country 186 5,098 12,540 (TB per day) ►Significantly, at least 80% of the traffic volume remains generated by users, leading to large variations of the total mobile traffic both in terms of time and space variations of traffic. ►Future mobile networks must be designed to cope with such variation of traffic and uneven traffic distribution, while at the same time maintaining a permanent and extensive geographical coverage in order to provide continuity of service to customers. ►These opposite constraints are some of the most significant future challenges for operators.
