We are the principal provider of fixed-line and mobile telecommunications services in Ireland. The Group provides a comprehensive range of advanced voice, data, broadband and TV services to the residential, small business, enterprise and government markets. In 2016, we acquired Setanta Sport and subsequently rebranded to eir Sport which we are now offering as part of enhanced value bundles to all broadband customers.
Our mobile division operates under the eir Mobile brand. In addition, our wholesale division, open eir, is the largest wholesale operator in Ireland, providing products and services to more than 70 national wholesale customers and 25 international wholesale customers, across a range of regulated and unregulated markets.
eir Group revenue for the year ended June 30, 2019 was €1.25 billion and Adjusted EBITDA was €578 million. Since September 2012, we have invested over half a billion in a Next Generation Access ("NGA") network that provides fibre-based services to customers mainly through the deployment of Fibre to the Cabinet ("FTTC") and Fibre to the Home ("FTTH"). At 30 June 2019, we had passed over 1.9 million premises with fibre, including 307,000 with FTTH, reaching 83% of the Irish population and enabling broadband speeds of up to 1 Gb/s for our customers.
We are committed to working responsibly. In 2016, eir was awarded the Business Working Responsibly mark, which certifies our policies and practices across our business including CSR, HR, Environment, Workplace, Marketplace, Diversity & Inclusion, Product Development and Sustainable Procurement.
We are the largest provider of fixed line telecommunications services in Ireland, offering broadband, voice, TV and data services to individual consumers and business users. We also offer wholesale access to our network to other authorised operators ("OAOs").
According to quarterly data published by ComReg (ComReg 19/82), we had a market share for the quarter ended 30 June, 2019 of 41% of the Irish fixed line market, based on revenue. We have the most extensive fixed line telecommunications network in Ireland in terms of both capacity and geographic reach, and other network operators therefore rely heavily on our infrastructure. We are also the leading provider of broadband services in Ireland with 464,000 retail lines as of 30 June, 2019.
As at 30 June, 2019, we had over 1,147,000 fixed line retail and wholesale telephone access lines (excluding wholesale LLU) in service, of which 944,000 (excluding line share) were retail and wholesale broadband customers. As at 30 June, 2019, 74% of our broadband base is on fibre. Approximately 96% of our active access lines are in exchanges enabled to support both PSTN and ADSL permitting simultaneous, high-speed transmission of voice and data over our network.
We are the third largest mobile operator in Ireland in terms of revenue and customers. In 2013, eir was the first market with high speed 4G data services in Ireland and eir has currently achieved an estimated 96% 4G coverage in the Republic of Ireland. As of 30 June 2019, our Mobile division had 1,023,000 customers and we had a share of 19% of the Irish mobile market, based on number of subscriptions (excluding mobile broadband and M2M) based on ComReg market data.
