4. Conclusion
The main challenges of energy-efficient wireless networks are summarized here. The Cell Breathing method, as well as implementation issues, are discussed.
The trade-offs between coverage, operator costs and energy consumption are put into perspective. The principle of evolutions of this method, in particular the association with femtocells or relays, is also introduced.
