Telecommunications operators are concerned about the impact of this heat wave on their infrastructure networks. Just as heat waves can affect smartphones, tablets and other laptops, the infrastructure underlying telecommunications networks can also suffer in hot weather. Indeed, the electricity network, which is heavily solicited and subjected to high temperatures, can fail this equipment. They can then stop working in a punctual and localized way.
But the real "vulnerability" of these infrastructures is concentrated on two specific network points: relay antennas and data centres. Depending on the equipment considered, the temperature threshold not to be exceeded is around 50 degrees Celsius.
Relay antennas are particularly exposed to high temperatures since they are located at high altitudes, particularly on the roofs of buildings in urban areas. The risk of their electronic components going into standby mode in the event of overheating is therefore not negligible.
Depending on their air conditioning systems and exhaust air devices, data centres risk overheating if they fail to operate.
All the attention of the operators is focused on not exceeding 50 degrees Celsius. "We have set up a weather monitoring system to enable us to prevent in the event of a natural disaster and to analyse the good performance of each point of our network [...] Over the past few months, we have focused our preventive campaigns on monitoring the maintenance and air conditioning equipment in our infrastructures for greater safety", explains Hubert Bricout, Bouygues Telecom's Regional Director for Ile de France and the North-East.
In the event of a site failure, rapid response teams will be dispatched. To support the systems already in place, mobile air conditioning equipment has also been reserved in the event of overheating of a network point.
