Abstract:
In this paper we present a Digital Boarding
Assistance (DigiBa) system
for passengers in airport terminals. By
providing navigation,
notification and information services,
passengers are enabled to move
efficiently through the terminal. Based
on functional requirements of
such a system, the paper presents a
prototype implementation on an
embedded mobile device with restricted
resources. Challenges
concerning channel access in dense networks and
indoor navigation on
a device with limited hardware capabilities are
outlined.

Abstract:
This report describes usage scenarios of the
architecture for indoor navigation and location
based services (INLBS)
developed in the Airport2030 project. The expandable architecture
offers a framework and predefined services with a runtime environment
and aims at enabling
ubiquitous INLBS in any building with the users’
mobile device.
The architecture consists of a mobile user platform
(MUP) installed on mobile devices and
a stationary facility platform
(SFP) which is running on backend servers. For communication
between
MUP and SFP a communication and positioning infrastructure (CPI) is
used. The
SFP abstracts from different mobile hardware and
communication and ranging technologies
for ease of development. A
runtime environment contains the service container which invokes
life
cycle functionality of the different services. Applications which are
accessed from the
MUP are developed using the services in the service
container.

Abstract:
Outdoor navigation services have become ubiquitously
available due to small
handheld devices such as GPS enabled mobile
phones or dedicated
mobile navigation systems.
Two main drivers were
necessary in order to provide widespread location
based services:
Acquiring positioning information with a certain
degree of precision
and widespread (mobile) access to
computer networks to use the
position information with a large information
basis such as the
Internet. Envisioned is a future, where indoor
navigation and location
based services are used as
naturally as outdoor location based
services are now. To achieve this long
term vision where users
seamlessly navigate for example
from work desk to departure gate at
the airport and use location based
services on the way, various
challenges have to be solved.
In this paper, these challenges and open
issues are discussed. The
paper proposes an architecture which
abstracts from different
mobile devices and localization technologies.
Additionally, it sketches the
use of indoor topology information to
increase the
accuracy of indoor localization. These two presented
concepts form a basis
for a transition period until standards for
ubiquitous
indoor location based services have emerged.
