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).
