Telecommunications Networks |    |
The growing needs of telecommunications operators, particularly in the field of cable and mobile communications, has generated a significant demand for new made-to-measure services and technological solutions.
AT4 wireless provides a response to these new requirements and the significant technical challenge they present, offering the following portfolio of services:
- Certification of telecommunications networks under construction.
- Quality control and adjustment of telecommunications networks in use.
- Measurement of telecommunications infrastructures in accordance with the applicable regulations.
- Specialised training.
- Functional evaluation of terminals for network connection.
- Field trials for GSM network devices for terminal manufacturers.
- Fields trials for GSM / UMTS terminals and services for operators.
- Design of testing tools and data capturing systems which can be integrated into management systems to enable analysis.
AT4 wireless offers these services based on the extensive experience of its laboratories; innovations in the field of measurement methodology; architecture of distributed measurements; information technologies for displaying results (web), and the treatment, processing and management of results, incorporating correlation with network elements, its internal features and historical development.
AT4 wireless has the necessary structure for "In situ" measurement (customer and field facilities). and the logistics and coordination of mobile units across the whole national territory. In addition, thanks to the experience accumulated in recent years, we can offer a global quality control and supervision service for any type of operator regardless of the technology used.
