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

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, …

is a critical problem!


TD-LTE is gaining momentum

TD-LTE is considered within BeFEMTO as a potential solution for Femtocells.
e.g. TD-LTE Overlay within FDD Uplink (UOULU).


LTE Deployment

Time-window opportunity
For new markets!

BeFEMTO Project Timeline is well aligned: Not too early nor too late.
(drafting of proposal was back to late 2008/early 2009!)


LTE Operator Commitments
Faster than HSPA


HSPA Networks: 380 Commercial
systems


Global UMTS Subscriber Growth Forecast

HSPA+ will still play an active role
In near future, as migration
and complementary to LTE.

In BeFEMTO, Multi-Radio is
also investigated,
Together with some Testbeds.


LTE Ecosystem is maturing fast!

- 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
