Mission critical and UTCAL communication at ITU
Connection availability far below that required for utilities
Telephone operators operating in Brazil stood out in a recent survey conducted by Open Signal, showing improvements in all evaluated services. According to the survey “Mobile Network Experience Report July 2020”, which analyzed the user experience of Claro, Oi, TIM and Vivo for three months since March 2020, the services of voice applications, videos, online games and download speed / uploads continue to show improvement. But there is no reason to celebrate, in fact.
While Claro led in all these aspects, TIM was the absolute highlight in 4G connection availability – obtaining 88.2% – and lower latency. However, the scenario has little influence on the improvement of essential communication systems, seeking to guarantee the uninterrupted and safe operation of services provided by utilities or concessionaires in the energy, water or oil and gas sectors. For these systems, operating on a mission-critical basis, the minimum availability required by these communication networks – regardless of the technology used – is 99.89%, well beyond what telephone operators are able to offer with their 4G networks.
Other players are still trying to keep the order of 80% availability on 4G. If the telephony segment celebrates these advances, the energy sector needs to comply with the Network Procedures of the National Electric System Operator (ONS), which considers almost total minimum availability (99.98%), calculated monthly, for voice and voice services. “Class A” data, provided with independent telecommunications resources, made available through two independent routes, with an individual availability of at least 99.00%.
The demand for private networks in utilities is urgent, to meet more demanding requirements and, for that, dedicated spectrum for this use needs to be considered in the bands below 1GHz and in the frequency auction for the implementation of 5G. And it is in this sense that UTCAL has acted, with entities representing other sectors and the Brazilian IoT Forum, and in contact with regulatory bodies.
In July, the association was strongly involved in meetings of the International Telecommunication Union (ITU), to achieve further progress towards a base document with all the requirements and details on the demands of communication in utilities worldwide. The result will be shared with bodies such as Anatel, Aneel and the Ministry of Mines and Energy.
