BeFEMTO Objectives & Approach

Overall Goal
To research & develop evolved LTE-A based femtocell technologies that accelerate cost-effective
provision of ubiquitous broadband services by convergence b/w fixed and wireless broadband

Approach
Near-term solutions: Novel techniques for standalone femtocells for early deployment
Long-term solutions: Novel concepts of networked femtocells, fixed outdoor relay femtocells
for enhancing cell-edge capacity, and mobile femtocells in public transport, all with SON
capabilities for minimising OPEX and simplifying remote network management
Validation: Through 4 experimental testbeds, mathematical analysis, and simulation tools

Objectives
High Spectral Efficiency: 8 bits/s/Hz/cell
Maximum Mean Transmit Power: 10 mW
Support infrastructure and spectrum sharing
Enabling new services for home, enterprise and mobile (transportation) environments.
New and novel use of femto technology in outdoor environments


BeFEMTO Challenges

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

(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.
