Packaged or customised, the extensive range of GRANIOU solutions, as well as its capacity to provide multi-technique and multi-skilled responses make it possible to put together modular and customised offers that dovetail perfectly with the needs of each of our clients whether they are operators, manufacturers or local authorities.

GRANIOU's uniqueness and strength are attributable to the combined expertise in:

Through its global and open-ended offering, GRANIOU contributes to:

• Ensuring the rollout and maintenance of UMTS systems;
• Improving the quality of GSM communications operators' coverage;
• Taking into account health and safety standards from the initial network design stages;
• Providing better environmental protection through the committed integration of radio communications sites into the landscape;
• Fostering the creation of wealth for operators and local authorities by reengineering their existing infrastructure;

• Optimising rollout plans of ADSL and LMDS operators for the construction of access networks;
• Getting the most out of operators' fibre optic infrastructure equity;
• Integrating new operator backbone equipment from their European NOC operations;
• Maintaining user service quality by ensuring the professionalism of the teams in charge of maintaining networks in operating condition.

To respond to customers’ objectives for capacity and coverage, network availability, service quality, the management of assets and technological developments, five separate offers, adapted to meet these requirements, have been put in place. In the case of each of these offers, Graniou knows how to operate in project mode when volume and technical requirements demand this.

We design, install and maintain the entire infrastructure from passive components through to active equipment.
