IP and the optimized wireless backhaulThe ‘state of the planet’Ottmar Krauss

Transport product marketingNokia Siemens Networks


Packet transformation is happening now

79% of operators have plans to go to Ethernet(Infonetics 2011)

100% of BTS transport modules delivered by Nokia Siemens are Ethernet ready

More than 120 of Nokia Siemens customers already use packet transport in HSPA areas

Ethernet is the chosen network service –enabled by various types of network architectures

Backhaul based on Ethernet services (E-Line, E-Tree, E-LAN)

NETWORK & ARCHITECTURE (i.e., the Infrastructure for the Eth services):

IP/MPLS, NGSDH, MWR, Carrier Ethernet, DWDM with L2 Switch, PTN, P-OTS

… transported over any sort of architecture

Ethernet is the service …


But things are never that easy…

E2e backhaul management is inevitable: interworking and mapping of services and architectures is key
