Latin America. An infographic from 5G Americas on mobile technologies revealed, until the first half of 2018, the existence of 18 cellular networks that have deployed LTE-Advanced (LTE-A) technology – usually marketed under the acronym of 4G + or 4.5G). This represents 47.4 per cent of existing mobile networks, or almost half of them.
The countries that have deployed LTE-Advanced are Argentina, Brazil, Chile, Colombia, Ecuador, Peru and Uruguay. On the other hand, Bolivia, Paraguay and Venezuela have not yet deployed this technology and offer services under LTE.
LTE-Advanced technology is an evolution of the LTE (4G) standard, first defined in Release 10 of the 3rd Generation Partnership Project (3GPP), which provides higher connection speeds. According to the 3GPP, LTE-Advanced offers peak speeds of 3 Gbps for download and 1.5 Gbps for upload. Among its main advantages, it offers Carrier Aggregation, improved use of multiantenna techniques, and support for Relay Nodes, allowing it to offer higher transfer rates, better performance and efficiency in the use of resources.
In addition, the 5G Americas survey shows that just under half of cellular networks in South America (44.7 percent) operate using the 700 MHz spectrum band. The 700 MHz band, also called "digital dividend", is used by many operators in Latin America to offer carrier aggregation and thus reach LTE-Advanced speeds.
