LTE is now a mainstream wireless technology that is leading the latest wave of growth among mobile subscribers around the world. With 393 networks already commercially launched in 138 countries, LTE is expanding its reach to new market segments for applications that range from consumer and enterprise to public safety and more. VoLTE rollouts are picking up rapidly, and the migration to LTE Advanced is also under way in mature global markets. C-RAN, deployments in the unlicensed spectrum (LTE-U, LAA), Small Cells for enterprise and home usage, and cellular IoT/M2M are some of the future trends in LTE deployment.
