Solar Energy Suppler

Currently working with WINS Ltd as a Senior Network Engineer focusing on GSM installations on board cruise liners and ferries. My work is more focused on the GSM BSC area of the projects. Since I have joined the company I have enabled GPRS service on board the vessels thus adding another revenue stream to the company. Specialisation includes working on BSC/BTS nodes, being the reference contact for issues related to interfacing with MSCs and SGSN nodes. I also handle issues related to roaming bilateral establishment, while leveraging on the experience acquired during my previous work experience as a CS Core Network Engineer. Coupled with this, the installation on board vessels, involves also the deployment of Distributed Antenna Systems, which when interfaced with our NanoBTSs on board spread the radio signal to provide good coverage in all the areas of the vessel.In order to monitor such a dynamic mobile network, which has shifting traffic patterns depending on vessel routes, operating times and people on board and also the quality of the satellite link, we had to develop quite an extensive KPI subset to be sure that traffic drops are due to lack of customers wanting to use the service rather than an issue with the network itself. For this reason, part of my daily work involves analysing traffic patterns, with input from the various network elements, and also from external entities including vessel GPS position, operating timetables and also CDRs from the different roaming partners. This is mainly done through the use of mySQL DBs which feed directly into pivot tables which enable fast and efficient data handling.
