Key features of future mobile
and wireless networks
nImproved radio technology and antennas
–smart
antennas, beam forming, multiple-input multiple-output (MIMO)
nspace division multiplex to increase capacity,
benefit from multipath
–software
defined radios (SDR)
nuse of different air interfaces, download new
modulation/coding/...
nrequires a lot of processing power (UMTS RF
10000 GIPS)
–dynamic
spectrum allocation
nspectrum on demand results in higher overall
capacity
nCore network convergence
–IP-based,
quality of service, mobile IP
nAd-hoc technologies
–spontaneous
communication, power saving, redundancy
nSimple and open service platform
–intelligence
at the edge, not in the network (as with IN)
–more
service providers, not network operators only
