Mbps, wireless local area or home networks more than 100 Mbps networks,
wired-home networks 200 Mbps for HomePlug, 10-100 Gbps for Ethernet.
For wide-area networks, the offerings vary from provider or subscription,
from 1 Mbps to more than 100 Mbps.
Ease of installation is an important issue, especially for existing houses. The
ideal is to use no new wires, which means in practice using wireless
technology (WiFi) or recently using power-line (Homeplug). This might be a
solution with respect to hardware but software configuration problem,
configuring firewalls, network address translators etc. still remain. Solutions
from the area of dynamic composition could help here and with a transition
towards IPv6 auto configuration could mean progress.

Personal or body network context
In this context, the connectivity, communication and data exchange from PAN/BAN
devices between each other and with one or more devices in the LAN network is
realized. This means that besides basic connectivity and communication protocols
message formats are also important. Potential technologies are:
basic connectivity and communication: IEEE 802.15 (1.3a., 4a, 4.6),
Bluetooth, Bluetooth low energy, ZigBee, Z-wave, USB, UWB, RFID and
NFC.
•
The network should be able to handle dynamic configurations, so that registration
and discovery or pairing protocols are needed. Potential technologies are:
Bluetooth, ZigBee, Z-wave;
•
•
UPnP;
device profile for web services.
•
Security is a topic when it relates to safety (prohibiting unauthorized access to
certain devices and especially to the application-hosting device) and transfer of
sensitive data (e.g. healthcare data). Important issues here are: pairing procedures, bi-
directional authentication, certificate handling and encryption.
5.5.4.
Local or home network context
In this context, the connectivity, communication and data exchange between devices in
a local area network is considered and basic connectivity and communication protocols
and standardization of messages is important. Potential technologies are:
Basic connectivity and communication:
IEEE 802.15 (1.3a.4.6), Bluetooth, ZigBee, Z-wave, UWB, Homeplug (using
in-home power-line);
•
Internet protocols and web based protocols (http, https);
•
specific networks, some usable on several physical layers, in local setting
might be used e.g. in the home control area: X10, or more recent alternatives
LonWorks, and INSTEON. KNX, the successor to three previous standards:
