Transport Network Technology Evolution – Physical Medium

• Microwave Transmission & Transport Network

• Boom in data services (HSPA+ / LTE) drives the needfor Fiber Optic deployment in Backhaul and even inAccess layer.

•Dense Wavelength Division Multiplexing (DWDM)technology evolves from nx2.5/10/40Gbps and soon tonx100Gbps per fiber pair.

• NG-DWDM incorporating L2 functionality is already arealit .


• Passive Optical Network (PON) and NG-PON in theAccess network permitting to further increase capacityby providing 1 Gbps connectivity for each customerexpected to be available soon.



Transport Network Technology Evolution – From TDM to IP

• Circuit Switching – TDM technology

• Started with PDH over Microwave(up to 140 Mbps)

• Continued with SDH over

Microwave n x 155 Mbps (n usuallyup to 6)

• Evolving to SDH and NG-SDH overFiber

• 2.5 Gbps and 10 Gbps

• Su ort of Ethernet services

(mapped over TDM networks)

• Packet Switching – IP technology

• Using mainly IP/MPLS both in thecore and in the Backhaul parts of thenetwork.

• Carrier Ethernet also an option forbackhauling purposes.

• Trying to handle the packet trafficexplosion and the strain in theBackhaul networks.

Greek Mobile Market Economics

• In 2008 the revenue from mobile services

reached ~€4,7 billions…

… accounting for ~1,9% of the national GDP


• Mobile operators make ~ €0,5 billions of investments annually whereasthe investments up to date have reached ~ €5,5 billions…

… which support a market that maintains ~28000 job positions (~7000

job positions in mobile operators)
