Capabilities used

To carry out the Serena Telecare Platform development project, OESIA used both technical and organizational capabilities to successfully complete the development project.

Main technologies used:

Other companies or players involved

The project is based on a need, raised by Orange together with Ilunion.


The project consisted of creating a platform to offer telecare services to elderly or dependent people in order to provide assistance, peace of mind and security to them and their families.


To create the Serena Telecare platform, OESIA carried out a software engineering project by performing the following main tasks:

  • Analysis and design.
  • Construction.
  • Tests.
  • Implementation and deployment.

The project management methodology for the control, monitoring and organization of activities is based on the PMBOK®(Project Management Body of Knowledge) standard, a body of knowledge on project management developed by the PMI(Project Management Institute).

The project was carried out under a framework where security was fully integrated in all phases of the development cycle. To this end, OESIA will use globally recognized security methodologies.

Likewise, the telecare platform had to meet all accessibility standards, taking into account the needs and target audience.


To create the Telecare platform, all the actions of a software engineering project were carried out to develop and implement the telecare system, which consisted of the following components:

  • Mobile application. Allows emergency calls, geolocation, private chat, agenda and alerts.
  • Telecare Web. Portal for the realization of the assistance service.
  • Family website. Consultation and follow-up application for family members of assisted persons.
  • Web ordering. Serena service order management application used at points of sale and by sales managers.

OESIA developed the Telecare platform in such a way that it allowed, in a friendly and attractive way for the users of the service, to perform Telecare operations. The platform was developed based on the following principles:

  • Scalable platform: The platform contemplated the possibility of introducing new functionalities in a modular way. Moreover, the platform was deployed on the AMAZON AWS cloud, so it could be easily sized according to the evolution of the load.
  • Permissions and roles: the platform allowed to select the information and functionalities that would be shown to the user according to his role.
  • Platform with a graphic interface that complied with accessibility standards following the WAI-WCAG guidelines at level AA for web environments and that allowed the information to be displayed adapted to the required look&feel.
  • Graphic interface adaptable to different devices. The graphical user interface was Responsive Design adapting to smartphones, tablets and PCs.
  • Traceable platform: the platform was developed in compliance with the principle of traceability, so that any operation on it will be recorded for any subsequent analysis.
  • Secure platform: the platform was developed under a framework where security is contemplated in all phases of the project and had the necessary security controls to ensure the confidentiality, integrity and availability of the information.


The result was that both Orange and Ilunion were able to provide a Telecare service, called Serena, both in remote and face-to-face mode, relying on the telecare platform developed.


Family of SATCOM On The Move (SOTM) terminals for vehicular installation and stable mobile connection

SGoSat is a family of high-tech SOTM (Satellite Comms On The Move) terminals that are installed in a vehicle, providing the ability to target and maintain a stable connection to the satellite when the vehicle is in motion in any type of conditions.

The SGoSat family is composed of versatile terminals, which can be installed on any type of platform: trains and buses, military and/or government vehicles, aircraft, ships, etc. Originally designed for the military sector, SGoSat terminals are extremely reliable and robust, integrating high-performance components that comply with the most stringent environmental and EMI/EMC regulations. The product uses low-profile, high-efficiency antennas and a high-performance positioning and tracking unit, allowing the terminal to be operated anywhere in the world.

In order to meet the diverse needs of its customers, INSTER has developed single band and dual band terminals in X, Ka and Ku frequencies.

The SGoSat family of terminals can also be configured with a wide range of radomes (including ballistic options) to suit customer requirements.
