MIMO allows for higher peak data rates and increased spectral efficiency, which provides higher network capacity. – HSPA multi-carrier technology with MIMO, which is currently being standardized, is scheduled for commercial deployment in 2010. By the end of 2009, Ericsson will support commercial deployment of multi-carrier technology with speeds up to 42Mbps - an achievement successfully demonstrated at the recent Mobile World Conference in VICTOR MANUEL QUINTERO FLOREZ Barcelona.

But what happens if the network is overloaded or even off the air as a result of the disaster? Soon it will be possible to borrow free space in other frequency bands or to organize an ad hoc communication network on the spot thanks to ‘cognitive radio'. This means that the scarce space available will be put to better use. – Cognitive radio can identify all transmitting and receiving possibilities in the vicinity and utilize them to the full. – This does require a totally new approach to the radio spectrum: instead of the current highly channelled approach, cognitive radio tries to borrow bandwidth in other bands, without disturbing the users of these bands.
