The 12th GTI (Global TD-LTE Initiative) workshop took place during Feb. 26-27 in Barcelona, Spain, gathering more than 120 industrial leaders and experts from 32 operators and 27 industrial partners and organizations to share latest progress and discuss key issues about TD-LTE commercialization.

This time, aside from the regular plenary, the GTI workshop was reshaped into a topic-oriented structure with joint sessions focusing on LTE-A, Roaming, VoLTE(voice over LTE), 3.5GHz, RCS(rich communication suite), and business models and funding, putting stress on end-to-end subjects and issues. Operators were sharing updates and progress on LTE TDD/FDD convergence, carrier aggregation, and end-to-end requirements to deliver eMBMS (evolved multimedia broadcast multicast service), communicating with industrial partners about VoLTE and RCS technical and business considerations, and addressing key issues regarding 3.5GHz ecosystem and devices, multi antenna CPE, and revenue models and funding for TDD operators. A white paper of Business Models and Funding was also introduced at the workshop.
