Fixed vs. mobile – it’s a “last mile” discussion
The bulk of data traffic is served by fixed networks, the last mile to the end-user is fixed or wireless, depending on user requirements

Fixed broadband access will continue to offer higher data rates than wireless

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

Wide area wireless systems are limited to ~100MB/sHigher data rates are only feasible for local area coverage

Energy efficiency of fixed and wireless
3B mobile subscriptions produce ~22Mt/a CO20.4B fixed broadband connections emit about the same amountThere are more mobile subscriptions than usersThere are more users than broadband connectionsThere’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
