Monitoring of Telcotowers in Latin America

Service Provider for Mobile Network and Mobile Data Services

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. Thhese 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.

» Repairs and maintenance are complex and cost-intensive

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. As a result, the provision and quality of mobile communications services suffer. 


The intelligent solution was developed on the basis of the azeti platform. Our customer can now 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. It 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.  Thus appropriate countermeasures can be taken at an early stage to limit climate-related performance restrictions.

» Early intervention with targeted measures
The data is collected around the clock and evaluated directly on site. As soon as a deviation, such as a drop in battery power or irregularities in diesel consumption, previously selected groups of people are immediately alerted by e-mail, SMS or slack notification. The maintenance teams then have the opportunity to intervene immediately and prevent costly damage at an early stage. In order to be able to initiate specific remedial measures, the current status of the transmission system and specific information about the fault is displayed in advance in an app. Unnecessary trips due to missing equipment or wrong spare parts can thus be avoided. A history provides information about past events and allows, for example, forecasts of future disruptions, especially with regard to climate-related irregularities.

Another positive side effect is the extended service life of the battery due to regular use. Similar to cars, they too must be requested regularly in order to function properly. This resulted in the special solution: the Battery Health Assistant.

Battery Health Assistent

The Battery Health Assistant is based on azetis AEP (Application Enablement Platform), using some core features such as software-based automation and edge computing. 

The Battery Health Assistant regularly checks the condition of batteries. This is done by automatically placing a load on the batteries at regular intervals by switching the power supply from the generator or, if necessary, the mains supply to battery operation. It then measures how long the voltage of the battery is maintained and what causes the voltage drop. This load cycle is performed at least once a week. The voltage is measured continuously and based on the historical data of the battery it is possible to predict when replacement is recommended. A notification is displayed in the user's dashboard.

With edge intelligence, the Battery Health Assistant operates completely autonomously and does not require a connection to the cloud.


All measures led to a substantial reduction in the costs of operations and an increase in service quality in the area of mobile communications and data services.

  • Drastic reduction of the downtimes of mobile phone towers
  • More efficient planning of maintenance teams
  • Targeted and fast maintenance
  • Immediate rectification of faults or failures
  • Correct loading of equipment and spare parts
