solar energy available in isolated areas and increases
the charging speed of mobile device batteries.
The application of the research generated a significant
impact in the isolated rural communities where the
experimental work was developed, enabling the use
of mobile devices with recharging based on solar
energy, increasing the possibilities of communication
and access to digital information for their inhabitants
and contributing to reduce the existing digital divide
between isolated and urban regions.
Future Research Lines
In isolated regions, cellular network coverage is very
low, if several devices are connected simultaneously,
the cellular network becomes congested and mobile
applications that make use of the Internet become
unstable, generating a large number of retransmissions
that degrade performance and increase drastically the
energy consumption of the devices, making it impossible
for the residents to access digital content. To overcome
this drawback, the following lines of research emerge:
• Introduce improvements in communications through
the use of cellular signal amplifiers, or the use of other
technologies to access the Internet (satellite connection
or radio link). It is proposed realize a comparative study
of the performance and energy consumption between
these technologies, for this and considering the energy
limitations of the isolated regions, some questions
are raised: How much energy does communication
equipment require? How to provide energy to this
equipment? What techniques to use to characterize the
energy consumption of the equipment?
• Use of Intranets with recharging based on solar energy,
as an alternative to enable people from isolated rural
communities to access digital content. This solution
is based on low energy consumption technologies
that allow the use of renewable energies The use of
simple board computers (Raspberry Pi type) is proposed
to mount the servers, in which the applications and
digital content will be installed. These contents will
be accessed from mobile devices using wireless
communication technologies (Wifi or Bluetooth).
