Customer case

Supervision of TD-LTE network implementation


A country’s leading operator decided to launch an LTE network, aiming at also becoming the leader in 4G. He needed to make sure that the design and technical implementation provided by his parts manufacturer was suitable to his business case, and that the time-to-market was nailed down.


Sofrecom supervised the entire roll-out by providing a dedicated team, which focused on reviewing the design documents (HLD, LLD) and on analysing the final acceptance documents and the technical documentation given by the supplier. Our consultants also supervised the installation and commissioning of the hardware, making sure that standard procedures were being obeyed.


Our work has enabled the customer to launch all of his services on schedule. We succeeded in renegotiating the acceptance thresholds and in adding tests to ensure a high-quality implementation. In addition, it was possible to correct the implementation of certain functionalities and to improve the technical documentation, a useful step with respect to future roll-out phases. Lastly, the operator’s team enjoyed a skills transfer.
