Motorola Demos 70 Mbps Downlinks in TD-LTE Trial in China

Motorola completed an Over-the-Air (OTA) trial of Time Division Duplex Long-Term Evolution (TD-LTE) technology in collaboration with leading mobile operators in China. Key trial achievements include:

  • Download throughput up to 70 Mbps in a 20 megahertz (MHz) bandwidth channel

  • Mobility and hand-over with live applications

  • Multi-User Equipment (UE) testing under one sector

  • All trial results have been submitted to the LTE/System Architecture Evolution (SAE) Trial Initiative (LSTI).

In addition to the collaborative trials with operators, Motorola said it is actively engaged with the TD-LTE trials initiated by China's Ministry of Industry and Information Technology (MIIT) as part of its efforts to develop a globally competitive TD-LTE industry.

"Motorola is committed to broadband and 4G developments, and supports both TD-LTE and Frequency Division Duplex (FDD) LTE. We've made significant progress in TD-LTE commercialization as demonstrated by these trials," said Dr. Mohammad Akhtar, vice president and general manager, Home and Networks Mobility, Motorola China. "The development milestone we're announcing today shows that Motorola remains on track to come to market early with field-proven, end-to-end LTE solutions to support TDD and FDD deployments. It represents our latest efforts to fulfill Motorola's commitment to support operators around the world in delivering true media mobility experiences to consumers at home and on the go."

Motorola also noted that these TD-LTE trials are been built upon its commercialized Orthogonal Frequency Division Multiplexing (OFDM) solutions and a number of LTE successes. Equipment involved in these trials is based on Motorola's second-generation OFDM products including Motorola's Base Band Unit (BBU) that supports TD-LTE, FDD-LTE and WiMAX, and features a Remote Radio Unit (RRU) that supports 2x2 Multiple Input Multiple Output (MIMO).
  • Earlier this year, Motorola deployed a live 700MHz LTE demonstration network in Las Vegas, replicating itsl 2.6GHz live LTE experience in Barcelona.
