  journal={Bell Labs Technical Journal},
The traffic load in mobile networks is very unevenly distributed both over time and over cells. Excessive waste of energy occurs in low traffic situations since the radio system is optimized for maximum load. Drastic improvements can be achieved by adapting to the actual traffic demand. The solutions we introduce below rely on automatically switching off unnecessary cells, modifying the radio topology, and reducing the radiated power with methods such as bandwidth shrinking and cell micro-sleep… CONTINUE READING
