In-Depth Information
the European Home Systems Protocol (EHS), BatiBUS, and the European
Installation Bus (EIB) is a widely accepted (CENELEC, ISO, ANSI) protocol
for home control and is able to run across several physical layers.
Data exchange:
in the healthcare sub-domain a number of standards for data exchange exist
like ISO/IEEE P11073-10404, USB device class for personal healthcare
devices, Bluetooth health device profile.
•
•
in the home control and security sub-domains broad accepted technologies are
lacking.
The network should be able to manage devices and applications and to handle
dynamic configurations. Potential technologies (some of them shared with the personal
area networks) are:
Bluetooth, ZigBee, Z-wave;
•
universal plug and play;
•
•
device profiles for web services;
open service gateway initiative.
•
Security is a topic when it relates to safety (the prohibition of unauthorized access
to certain devices and especially to the application-hosting device) and transfer of
sensitive data (e.g. healthcare data).

Public area context
A personal device to a system communication in a public area connects the home or
mobile devices with services somewhere on the Internet and also to services on the
Internet with each other. In-home devices might use the in-home LAN interface to
connect to these external networks.
Connectivity in the wide-area network domain is mostly based on using the
Internet, hosted accessibly through different access networks:
•
landline based: ADSL, CATV cable, and fibre-optic to home;
wireless/mobile (GSM/GPRS, EDGE and UMTS and future technologies as
developed e.g. by 3GPP), wide-area wireless broadband networks like
WiMAX.
•
Data-exchange facilities beyond the common Internet data-exchange facilities are
available through telecom services like SMS and IMS, which might be relevant in
mobile setting and as reminder service.
Besides the data exchanges between devices and services, remote control and
access through mobile devices like mobile phones is important, which further
emphasizes the need for security solutions.
The use of mobile devices with outdoor networks (mobile telephony networks as
well as wireless broadband networks) raises issues like availability of service, roaming
and hand-over solutions, and prioritisation in case of emergency.
