Winter in Europe will be difficult because of the energy crisis. In a worst-case scenario, French mobile networks Bouygues Telecom, Free Mobile, Orange and SFR could be down for several hours. This will lead to the deterioration or even complete disconnection of mobile communication services.

The current energy crisis, which is sharply increasing the price of electricity, could have even greater consequences due to RTE and Enedis’ planned blackouts in case of cold winters and low availability of nuclear plants. According to reports, the consequence may be the disconnection of the mobile communication network Reuters.

Hypothetical power outages may deprive the relay antennas of mobile operators (Bouygues Telecom, Free Mobile, Orange and SFR) of electricity. for a maximum of two hours. Mobile operator sites are not counted” sensitive ,” as opposed to hospitals or certain high-risk industries.

30 minutes of autonomy thanks to the batteries

You should know that in the event of a power outage, mobile network antennas can remain active for about 30 minutes thanks to the built-in battery. But if the outage lasts longer, the mobile network in the affected area will no longer be available.

Power outages are scheduled alternately, that is, in pairs, and for a maximum of two hours. Therefore, in the event of an outage in an area, it is possible that the service will not be completely interrupted, but will be severely degraded if another antenna that is still working covers the area.

What are the solutions?

Enedis, which runs the French electricity grid, the government and the French telecommunications federation are trying to find a solution. The government should add mobile operators to the list of confidential sites. But, according to an expert on the matter at the Ministry of Finance, “it is not easy to isolate the antenna from the rest of the network “.

In Germany, Deutsch Telecom plans deploy diesel generators to power mobile phone antennas in the event of a prolonged power outage. In France, according toonline magazine,Orange workswith the prefectures and the entire ecosystem so that as many sites as possible are marked as critical to reduce the impact of load shedding on mobile networks“.

Orange wants “the selected restriction zones allow you to continue to provide coverage there with the help of antennas installed in adjacent zones“. The stationary network of clippings will not be affectedas Orange shows that backup batteries can power the historic network for hours.

Mobile operators also complain about the very short time between Enedis’ notification of an impending outage and its commencement. The next day, the power grid manager plans to warn the operators the day before. In this case, planning a service continuity plan is difficult, even worse.

Sobriety measures on the part of mobile operators

The expert announces that mobile sites account for approximately 1% of the total electricity consumption in France. Orange still intends to reduce the weight of its mobile network on the electricity grid to reduce the risk of rotating load shedding by “switching several thousand fixed networks to batteries for one hour a day. This will save up to 20 MW during this period, that is, the instantaneous consumption of an average city with 40 thousand inhabitants.“.

For its part, the Iliad wishes to destroy “certain frequency bands at night, expanding the current system to 2100 MHz in 4G, 2100 in 3G and 3.5 GHz in 5G“then lets”reducing site power consumption by more than 10%“.

Electricity prices: is off-peak time interesting with the energy crisis?

In the energy crisis, many consumers want to check whether their electricity supply matches their consumption. It is very common for energy providers to recommend switching to an off-peak package and…
