The future
Human beings are nomadic or mobile by essence
Lucent Technologies – ProprietaryUse pursuant to company instruction
In the future
2 major trends of evolution Ad-hoc networks (temporary and locally) Network centric view User centric view
This will result in or require: Richer services Need of services frameworks Good supervision and management of the networks New and more efficient protocols Old “new technologies” might get a business case after all: e.g.
FTTH
And quite a degree of convergence in the “network”…
Lucent Technologies – ProprietaryUse pursuant to company instruction
Key areas
Key technology areas:
Access Networks: FTTH, xDSL,
Access Networks: 3G+/4G wireless interfaces
Service frameworks: data management and service intelligence
Nanotechnologies
All of this on a common IP/MPLS core network
Lucent Technologies – ProprietaryUse pursuant to company instruction
Network convergence IPv6 MPLS
Lucent Technologies – ProprietaryUse pursuant to company instruction
The NGN view of telcos
Several degrees of convergence
1. Transport layer: voice & data on the same backbone: IP/MPLS
2. Nomadicity: seamless roaming across heterogeneous networks
3. Fixed/wireless: services or applications are access agnostic
4. User convergence: only relevant information is presented – the technology is hidden

Why nanotechnologies ?
It will impact our relationship with machines and networks:
– Wearable microphones
– Compact batteries with low-discharge
– Distributed body sensors
– m navigational units (GPS, gyros)
Nanotech in the networks
Integrated systems on chip with MEMS design technologies (e.g optical systems)
– SOI flip-chip structures
– Monolithic structures (OADM, switches)
– Lens arrays
– MEMS SLMs
