Latin Island Case Study


The customer is a network operator on an island located in the Caribbean Sea, with the entire island covering approximately 21 square kilometers and a permanent population of around 3,000 residents. The operator provides fixed network, Fixed Wireless Access (FWA), and mobile network services to both island residents and tourists. Targeting the island's local community, the operator offers converged services including Mobile, FWA, and Fixed Line, operating on a postpaid billing model. For tourist users, the operator employs a prepaid model with one-time fees, providing 4G/5G mobile network services.

Customer Requirement

To provide and operate 4G/5G services, the customer requires a complete set of hardware and software products for base stations, core networks, and Business Support Systems (BSS). Additionally, mobile and fixed networks need to be seamlessly integrated through Session Border Controllers (SBC). The customer needs an end-to-end, lightweight, and integrated BSS system that supports service activation, provisioning, and billing for Mobile, FWA, and Fixed services. This system should also accommodate the management of different services and products tailored for both the local island community and tourist usage.

As the customer has a limited number of IT personnel, they can independently complete the installation and debugging of base stations and the deployment of the IDC with remote support. After setting up the servers and network in the data center, the supplier remotely handles the software installation and debugging, significantly reducing delivery costs.
