Conclusions & Future Work
• UMTS phase 2 needs
interworking between different
access networks:
– DECT, GSM, UTRA, USRA
– WLAN, Hiperlan
• Service mobility over FMI
networks
• Co-operation of Telenor:
– national: NTNU, Sintef
– international: Ericsson,
SUN, BT, EURESCOM
• Stepwise HW design
- HW receiver part
- Include transmitter
- Extend to full UMTS
• International co-operation for
full demonstrator:
– EURESCOM
– ACTS: SORT
• Final goal
– ‘cheap demonstrator’ for
research and development
– open architecture
– open API

Telenor UMTS demonstrator
UMTS phase 1 demonstrator:
– supplier solution, interfaces not
available
– limited experience due to
number of terminals
– limited hint for network
planning (capacity question)
+ Telenor is UMTS operator
+ gain experience on services
UMTS phase 2 demonstrator:
– not ready before 2001
– limited experience due to
number of terminals
+ open interfaces
+ extension towards
WLAN/Hiperlan
+ co-operation with research

The vision for Telenor
Be first in Europe to operate UMTS (in one area)
• limited area (Gjøvik, Steinkjær) at an early time, e.g.
Q1.2001
• invite Ericsson, Nokia, etc. to join the pre-operation
• operational equipment available, BTS & Mobiles
+
+
+
+
Telenor is UMTS operator
best public relation: first in Europe
gain experience on services
realistic (?) traffic, test for implementation of services
