Some 300 operators have commercially launched LTE networks in 107 countries, according to data released by the Global mobile Suppliers Association (GSA). Bulgaria, Taiwan and Vanuatu were the latest nations to experience commercial LTE mobile broadband service for the first time. LTE is available in 40 per cent more countries than a year ago. In 2014, 35 LTE networks have launched so far. The total number of commercial LTE networks is expected to exceed 350 before the end of this year. The most widely used spectrum for LTE deployments continues to be 1800 MHz (3GPP band 3), which is used in 129 networks either as a single band system, or as part of a multi-band deployment, in 67 countries. In addition, 36 LTE TDD networks are commercially launched in 24 countries, meaning that around one in every eight commercially launched LTE networks incorporate the TDD mode (sometimes referred to as TD-LTE). Some 23 operators have launched LTE service using only the TDD mode, and 13 operators have deployed both TDD and FDD modes in their networks. Release
