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”…

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 – Proprietary
Use pursuant to company instruction
Network convergence
 IPv6
 MPLS
Lucent Technologies – Proprietary
Use 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

Average Aggregate Data Throughput in 10 MHz (3G vs. 3G+)
Note: Capacities shown represent improvements as each feature is added to the features below it.
Note: Average Aggregate Throughputs
for CDMA2000 are for six 1.25 MHz
carriers (a seventh carrier could be
added if the 10 MHz of spectrum is
contiguous)

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
