3. Scenario
Complementing multiple heterogeneous access networks, including next generation high-speed satellite link in order to
Increase bandwidth
Increase reliability
- Broadband Internet connectivity has become increasingly important over the recent years and is nowadays considered “a crucial factor to realize economic growth”
- Hence, in this agenda the European Commission sets the objective to enable broadband
Internet connections of at least 30 mbps to be available to all EU citizens and 100 mbps to at least half of European
households by 2020.
- While this might be realistic in densely populated, urban areas it is a challenging task in rural
and other difficult-to-serve areas where traditional terrestrial current broadband technologies, such as xDSL or even (LTE) are economically unfeasible for operators.
- Next generations of fixed satellite systems are seen as one possible solution to address this issue [2]. Those systems,
which are scheduled to be operational by 2020, might lead to a Terabit/s satellite systems and will decrease the cost per
bit tremendously, which makes them suitable for reaching rural areas [3].
- However, satellite links will still introduce high latency on connections making it difficult for users to perceive a
high user Quality-of-Experience (QoE)
- Thus, using solely new satellite systems to provide broadband connectivity in rural and remote areas would not solve the
problem since the QoS demands, as expected in 2020 by the users, independent of their location cannot be meet
- Instead, complementing multiple heterogeneous access networks can be a potential solution to provide the required bandwidth
to the end users also in rural and remote areas while still allowing for a high QoS.
- By simultaneously using multiple connections higher availability, reliability and eventually a better QoE can be provided.

4. Challenges
Simply distributing traffic equally on a per-packet basis among many connections won’t work
Link Selecting Entity must take into account:
Capabilities of different connections
QoS requirements of traffic
 Capabilities (latency, capacity, jitter, loss) of each connection must be determined
 Traffic must be distributed intelligently

5. Relation to IEEE
Link selection should work independent of the underlying media. Hence, media abstraction mechanism is needed.
Generic event and command service required
Generic Monitoring events are required
Media Information Service can be exploited to provide the required information

6. Questions Does it fit to 802.21(.1)? Mobile nodes are not considered
Not handover related
If it fits, are members interested in considering this use case?
