Telecoms behemoth giant Philippine Long Distance Telephone Company (PLDT) has completed its PHP1 billion (USD23 million) network expansion programme allowing it to handle significantly more voice, data and video traffic, Rappler reports. PLDT president and chief executive officer Napoleon Nazareno says that as a result of the upgrade, the company’s enterprise customers will be able to rely on an even more robust and resilient end-to-end managed service than previously offered. Working with Cisco Systems, PLDT has successfully upgraded its national core network, while separately, it has used global network systems specialist Ciena to help upgrade its international network. The telco’s domestic fibre-optic network now spans 54,000km and is connected to three submarine cables linking the Philippines with a number of other countries, including the US and Hong Kong. Nazareno noted however, that more work needs to be done to improve PLDT’s services to contend with an anticipated surge in demand for data as more and more people buy smartphones. The PLDT official estimates that smartphone penetration will rise to around 30% in the next three to five years, up from the current level of 9%-10%.
