Fixed vs. mobile – it’s a “last mile” discussion
The bulk of data traffic is served by fixed networks, the last mile to the enduser is fixed or wireless, depending on user requirements
6
Fixed broadband access will continue to offer higher
data rates than wireless

The fixed user data rate is today some 30 times that of wireless, and both a
have similar evolutionary trajectory
FTTH/B/C: Fiber to the Home/Building/Curb
FTTEx: Fiber to the Exchange with copper connection to the subscriber

Data rates are only one part the story
¾ The data rate comparison ignores the impact of
range / distance of different technologies
¾ Fixed access can provide significantly higher data
rates over a considerably longer range
¾ Mobility can be only provided by wireless
¾ Faster rollout of uncovered areas with wireless
¾ Cheaper coverage of scarcely populated areas with
wireless
¾ Different CAPEX / OPEX distribution
Fixed and wireless are complementary technologies

Energy efficiency of fixed and wireless
ƒ 3B mobile subscriptions produce ~22Mt/a CO2
ƒ 0.4B fixed broadband connections emit about
the same amount
ƒ There are more mobile subscriptions than
users
ƒ There are more users than broadband
connections
ƒ There’s a completely different usage pattern of
fixed and mobile networks
We have currently no suitable scale to compare energy efficiency of fixed
and wireless access

Only fiber has the potential to cover the
growing data traffic in future
