Whereas 2017 closed with the renewal of the active optic fibre network, 2018 was the year of the new residential offer with major advantages for users. The new catalogue is based on simplifying the offer and allowing the customer to personalise the product. A key aspect is the option to integrate mobile phone services with services for the physical access of fibre with modular telephony.
This new catalogue has been possible thanks to the evolution of the mobile network and the convergence between landline and mobile telephony with a new generation IMS convergent core.
The commitment to strengthen and guarantee connectivity has been boosted by the modernisation of the signalling and the channelling of our international links, increasing the capacity to meet the growing needs for data traffic both in terms of national and roaming data.
Data storage services also require maximum guarantees of connectivity. Throughout 2018 Andorra Telecom has installed an optical transport network in order to handle hundreds of gigabytes per second from among the different data centres.
It has also maintained a policy of alliances with international companies. The signing of a partnership with Astellia has made Andorra Telecom its international shop window and has allowed us to benefit from its innovations and advances in network analysis.
Television via optic fibre also played a key role in 2018. At the start of the year, new functionalities were launched such as the option to watch via catch-up any programme on the Movistar + channels from the previous week or to go to the start of any programme that has already begun. During the year ambitious changes have been planned for 2019, such as the change of the television platform and interface and the renewal of all decoders and remote controls.
We have also made progress in the virtualisation of equipment, functions and services in order to respond to new requirements that combine flexibility, automation and scalability in real time.
The company has invested a total of 22 million euros, with the new IP television and the new optic fibre catalogue being the flagship projects. Other key milestones include improvements to the virtual switchboard service, the modernisation of the IP data and voice transport networks and an increase in the international voice and data links.
During 2018 we have also made a major effort to improve the mobile network, both in terms of coverage and capacity. The number of aerials per technology guarantees connectivity: 2G (134), 3G (155) and 4G (155). In the case of 4G, coverage has risen to 85 per cent of the territory, permitting download speeds of 400 Mbps and upload speeds of 100 Mbps.
We have also modernised the TETRA critical communications network, used by all the organisations that deal with emergencies, and which allows the interconnection of one thousand users via 28 stations.
The organisation is continuing to take on new challenges and implement new technologies that will result not only in technical changes, but cultural ones, as well as changes involving equipment and knowledge. In addition, the different groups are working on the preparation of mobile pilot trials for 5G technology, improving the landline network to offer speeds of up to 10Gb, allowing the development of virtual and augmented reality through micro-services programming, advances in virtualisation and applying automation with robots and artificial intelligence.
