Breitbandstrategie der Bundesregierung (2/2009)

• Bis Ende 2010 sollen die Lücken in der Breitbandversorgung geschlossen und flächendeckend leistungsfähige Breitbandanschlüsse verfügbar sein.

• Bis 2014 sollen bereits für 75 Prozent der Haushalte Anschlüsse mit Übertragungsraten von mindestens 50 Megabit pro Sekunde zur Verfügung stehen mit dem Ziel, solche hochleistungsfähigen Breitbandanschlüsse möglichst bald flächendeckend verfügbar zu haben.

Erhöhung der Bandbreiten

1. Effizientere Nutzung der Frequenzen (q.e.d.)

2. Höhere Frequenzbänder ermöglichen höhere Übertragungsraten

3. Dynamische Zellgröße (ri): Wo viel Datenverkehr benötigt wird, kleinere Zellen, sonst größere

4. Signalvarianten: Kombination von Amplituden-, Frequenz- und Phasenmodulation

5. Mehrere Antennen auf beiden Seiten (MIMO)

6. Kombination von mehreren Bändern, variable Bändernutzung

Grenzen von breitbandiger Mobilfunktechnik

• Ausbreitungsgrenzen von Wellen

• „Rauschen“ bei hoher Netzlast (Signalstärke, Durchsatz)

• Je höher die Frequenz, umso höher die Datenrate, aber umso niedriger die Reichweite

• Je niedriger die Frequenz, umso höher die Reichweite

De-coupling of revenues from traffic and traffic-related costsThe traditional linkage between revenues and costs via the traffic does not apply any more with mobile broadband

De-coupling/ gap

A winning mobile broadband strategyneeds to comprehensively address andpursue opportunities to

! Up-manage revenues and/or stabilize potential revenue losses

! Down-manage and/or limit costs

– via down-managing and/or limitingtraffic growth

– via down-managing relative traffic-related costs

Operators are required to manage the increasing gap between revenues and costs
