Eircom Limited (trading as Eir) is a fixed, mobile and broadband telecommunications company in Ireland, and a former state-owned monopolist. It is the largest telecommunications operator in the Republic, with a division to service the business & corporate telecom markets in Northern Ireland and Britain. As Bord Telecom Éireann, the company was state owned until 1999, when it was floated on the Irish and New York Stock Exchanges. Eir operates the fixed-line telephone network, an LTE (4G), HSDPA (3G) and GSM/EDGE (2.75G) mobile telephone network Meteor (acquired from AllTel (Western Wireless) in 2005) and acts as an internet service provider (ISP) eircom.net. As of Q1 2013, Eircom had 54% market share of fixed voice lines; 40% market share of fixed broadband; 11% of mobile broadband; and 17% of mobile.〔(Comreg ). Comreg.ie (13 June 2013).〕 By late 2007 Eircom added their 500,000th DSL subscriber but broadband share may have fallen to 44% due to growth of fixed wireless, cable and fibre services.〔See (ENN reports Comreg Sep. 2007 ).〕 Its main competitors are Virgin Media Ireland (which operates a cable TV & Broadband network), Vodafone Ireland (which bought BT Ireland's residential customer base on 22 July 2009 and is accessed through Eir's network and BT Ireland's fibre), Imagine Communications (Irish Broadband & Gaelic Telecom) and Magnet Networks and Smart Telecom, with a mix of LLU/GLUMP from Eircom and fibre. ==Services== Eir operates the largest fixed-line telecommunications network in the Republic of Ireland, under licence from the Commission for Communications Regulation. Most homes and businesses in the state are dependent on their network. A range of telecommunications services is provided on the network including Business IP, its MPLS platform. Eir have also completed a wholly owned fibre network ring around Northern Ireland and another around Belfast. Their ISP division, Eir Net, provides dial-up services, as well as broadband services (see broadband roll-out, below). Any alarm-monitoring products using SMS are "hardcoded" to work with Eir's SMSC, so will not work on Digiweb, BT, Smart, UPC or Magnet phone networks. DECT SMS handsets are also preprogrammed for Eir's SMSC. Any competing phone service that is not just carrier pre-selection (CPS) of Eir must provide their own SMSC, but even when they do, consumers may be unable to migrate from Eir due to SMSC numbers in equipment that cannot be reprogrammed. Eir's mobile arm, Meteor, provides a full range of HSPA/(3G) and GSM-based mobile communication services throughout the Republic of Ireland. Its GSM network operates at 1800 MHz and 900 MHz ranges, as the earlier GSM licences fully utilised the 900 MHz band. GPRS and EDGE data services are also available. Meteor have launched HSPA (3G Mobile Broadband) services in Dublin, Cork, Dundalk and Drogheda. Meteor provides both bill-pay (contract) and pre-pay (non-contract) plans and has approximately 19% of the Irish mobile market, with 1,032,000 cellular subscribers on the Meteor Network. The company has used EDGE technology on its network and has received a 3G (UMTS) license, formally removed from Eir's competitor, Smart Telecom (This required 33% of the population to be covered by 3G by September 2008.) As an operator with significant market power, Eir is required to provide a number of wholesale products to other operators and to switch calls onto other phone networks. Many broadband products offered by other operators are resales of the Eir product. A series of ''Eir Phonebook''s is distributed annually to all households in the Republic of Ireland. The six annual books list numbers in the local dialling area (01, 02, 04, 05, 06 or 07/09), regardless of whether the telephone service to the number is provided by Eir or by one of its competitors. Mobile numbers are not listed. The Commission for Communications Regulation (ComReg) has designated Eir as the organisation that has the obligation to provide a National Directory Database and Universal White Pages Phonebook. The unit within Eir responsible for providing a National Directory Database (NDD) and Universal White Pages Phonebook (UWB) is the Eir National Directory Information Unit (NDIU).〔(Directory Information Licence Agreement ).
