Demonstration Verifies LTE TDD/FDD Convergence and Roaming Capability

On June 7-9, 2011, world's first LTE TDD/FDD roaming was successfully demonstrated in China Mobile South Wisdom in Guangzhou. The demonstration signifies the industry move on the convergence of LTE TDD/FDD and verifies its roaming capability.

Demonstration configuration:

LTE TDD and FDD adjacent cells

Two RRUs (TDD RRU: 20MHz@2.6GHz Band38, FDD RRU: 2*20MHz@2.6GHz Band7)

Terminal: pre-commercial LTE TDD/FDD uni-mode, multi-band, single chipset USB dongle

Service: HD video streaming

During the demonstration, visitors experienced HD video streaming in a vehicle moving from LTE TDD cell to adjacent LTE FDD cell and back to TDD cell. HD video streaming were transmitted over LTE network through a LTE TDD/FDD uni-mode dongle, which will reselect TDD/FDD network while the current network cannot offer qualified service.
It is a typical deployment scenario for LTE TDD/FDD dual-mode network. The demonstration simulates the commercial global roaming scenario that user roams among countries with LTE TDD networks or LTE FDD networks. Similar mobile broadband user experience was achieved in both networks.

LTE TDD/FDD dual mode infrastructure equipment together with uni-mode single chipset terminal facilitates and proves the feasibility of LTE TDD/FDD convergence and roaming. It greatly enhances global operators’ confidence for LTE TDD/FDD dual mode network, and efficiently promotes the industry-wide movement on LTE TDD/FDD convergence and development.
