The customer is an international service provider offering mobile communications and mobile data services. For this purpose, it maintains several hundred telecommunication towers in various countries in Latin America. The towers are partly located in remote areas. Due to the difficult accessibility and the long distances involved, continuous monitoring of the functionality is only possible to a limited extent.
Mobile phone towers in Latin America are often exposed to extreme weather conditions such as tropical storms, which can cause considerable damage and resulting failures. In addition, the often high temperatures and an increase in humidity in this climate zone can lead to a drop in performance. Usually, a large part of the base stations are supplied with power, which is generated by diesel generators and batteries. In order to maintain operation, operators of these telecommunication towers must be informed at all times whether the power is guaranteed. In addition to power failures caused by weather-related damage, a too low diesel filling level can also impair the transmission power of the mobile phone towers. Expensive failures due to maintenance and dissatisfied customers are the result. Likewise, both maintenance and the replacement of worn out equipment are often carried out according to fixed cycles. Instead of proactively carrying out repairs or maintenance using smart solutions, they are usually only implemented when there is an urgent need. Especially when taking into account distribution in remote areas, there is enormous potential for our customers to save costs and time.
In addition, the transmission towers regularly become the target of theft and vandalism. It is not uncommon for any damage caused by this not to be noticed at an early stage, with the result that the provision and quality of mobile communications services suffer.
The intelligent solution was developed on the basis of the azeti platform. Our customer now has the possibility to detect pending maintenance, necessary repairs and the detection of damage from theft and vandalism at an early stage.
A standard IoT gateway is used for the implementation, which collects data from the generator, diesel tank, rectifier and the batteries on site at the mobile phone tower. The azeti Edge software communicates either via an interface with the devices or via retrofitted sensors. In addition, environmental parameters such as temperature and humidity are measured in order to be able to take appropriate countermeasures to limit climate-related performance restrictions at an early stage.
