Firm commitments to deploy LTE networks have been made in 150 countries by 497 network operators, according to latest research by the Global mobile Suppliers Association (GSA). Some 288 LTE networks have now commercially launched in 104 countries. The majority of LTE operators have deployed the FDD mode of the standard. The most widely used spectrum in network deployments continues to be 1800 MHz (3GPP band 3), which is used in 43 per cent of deployments. Some 124 LTE operators have commercially launched with 1800 MHz spectrum in 64 countries, either as a single band system, or as part of a multi-band deployment. 1800 MHz is the prime band for LTE deployments worldwide, and will greatly assist international roaming for mobile broadband, the GSA commented. The association recently confirmed that at least half of newly launched user terminals support operation in the 1800 MHz band, which now has the largest device ecosystem. Release
