- No fee: the user does not pay for the femtocell, and the monthly payment does not change (35€/month)
- Decrease: the user does not pay for the femtocell, and the monthly payment decreases by 5€ to 30€/month
- Increase: the user does not pay for the femtocell, and the monthly payment increases by 5€ to 40€/month

73. 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.
