Mobile operator Digicel Fiji is setting aside investment of FJD70 million (USD38 million) to expand and upgrade its high speed data network, in what it claims is its 'most significant investment' in the country since it launched operations in 2008. The operator will use the monies to roll out a new 4G network as well as ramping up coverage of its existing 3G+ infrastructure. Digicel CEO Darren McLean used the announcement to say the company is committed to changing the dynamic of the local market by ensuring end users have access to the fastest mobile internet services available. 'Customers are demanding more of our data network each month so we have made a big decision to enable all of our towers across the country with high speed 3G+ data capability. In addition to this we are also building the nation's largest 4G network in the main centres of Fiji. This means even higher wireless internet speeds of around 20Mbps in the key population areas,' he said. Since launching in Fiji in October 2008, Digicel has invested over FJD200 million in its networks and services. Under the latest 3G+ upgrade, work is already underway in the region of Lautoka, with several towns being added each day, he said. The current phase of this expansion is expected to be completed by the end of August, with the cellco then turning its attention to 4G. According to McLean, details of the proposed new ultra-high speed network rollout will be announced in the coming weeks.
