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 femtocellsfor enhancing cell-edge capacity, and mobile femtocells in public transport, all with SONcapabilities 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

Challenging working areas with potential for collaboration:� RF Signal Processing

� efficient, low-cost power amplifiers, highly sensitive receivers, flexible channel bandwidth, reliable RF

filters, …

� Interference Management

� coping with unplanned rollouts, macro-femto-coordination, coverage estimation, interference

cancellation, …

� Link and Access Management

� handover, admission control, resource management (s.a. load balancing and flow control), …

� Network Management and Architecture

� access control, authentication, local breakout, efficient forwarding, seamless mobility, zero-config, …

� Backhaul Issues

� wired or wireless backhaul, reducing signaling load, QoS provisioning and traffic priorization, …

� Low Cost and Low Power Implementation

� e.g. maintaining both coverage and capacity at very low transmit power

� Dynamic Bandwidth Allocation and Sharing

� multi-operator band sharing, flexible bandwidth allocation, backhaul sharing, …

Business Model

In BeFEMTO, four business cases are investigated:

- One off fee: the user pays 50€ once, and the monthly payment does not change (35€/month)

- 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

Mobile traffic forecasts 2010-2020

►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.

From 2010 to 2020, total daily mobile traffic in the representative Western Europeancountry will grow 67 times from 186 TB to 12540 TB.

data center using an encryupted tunnel when device is using an un-trusted (i.e. non-802.1x) Hotspot. All of the other applications get local break-out. I
