186 Software Networks
To interconnect BAN networks with the Cloud, a number of
solutions are envisaged: using the LTE network, or 4G, or a new
generation of Wi-Fi network. In the United States, the FCC is working
to develop a specific band for medical Wi-Fi, with much stricter
security standards than those in force in Wi-Fi today. The bandwidth
is 40 MHz, with a very low-consumption technology. The band for
such external connections would be between 2360 and 2400 MHz –
i.e. just below the current Wi-Fi band.
Other research, which is progressing well, regards the use of
integrated sensors in “smart dust” capable of circulating in the blood.
Analyses are regularly transmitted to external sensors which, in turn,
transmit to the Cloud.
6.27. The Internet of Things in the home
The home is a place where we find a large number of very diverse
sensors from different domains: ICT, telecommunications, medicine
and electronics. For instance, we find Internet beds which have
sensors that are able to detect all movements and speech during the
night to aid in the diagnosis of sleep problems. Doors, household
appliances, lightbulbs, security systems, etc., are, themselves, filled
with increasing numbers of varied sensors. Another example is given
by presence sensors, which detect whether or not a person is in a
room, with a view to automatically turning the lights on or off.
Overall, we expect to find around 100 sensors in every home by
around 2020.
There is a major struggle going on between household appliance
manufacturers, to determine which type of connection technology all
those sensors will use in the home. The base network uses Ethernet,
cable or Wi-Fi. Hence, most devices can be connected directly using
an Ethernet port or a Wi-Fi card. Bluetooth, 6 LowPAN, ZigBee and
NFC are also in the running. A communications controller should be
able to personalize all the connections and ensure they have adequate
security, good availability, reasonable energy consumption and as low
a cost as possible.
