  • Motorola: TD-LTE is Now a Commercial Reality

    Motorola has successfully deployed the world’s first indoor over-the-air (OTA) TD-LTE showcase network at the Expo Center at the World Expo 2010 in Shanghai. Together with China Mobile, Motorola is demonstrating end-to-end TD-LTE solutions at the Information and Communication Pavilion at the Shanghai Expo.

    Delegates are able to experience the real-life performance of TD-LTE via USB dongles, including video streaming, remote monitoring, video stream session and high-speed internet browsing.

    According to Motorola, a single TD-LTE USB dongle can stream 24 simultaneous video streams while supporting very high-speed internet browsing applications, at a total data rate of 20Mbps.

    A TD-LTE carrier in 20MHz can support transmission of a few hundred video streams simultaneously. Motorola claims that in the near future, TD-LTE subscribers will then be able to access a collection of high-bandwidth and low-latency internet applications including mobile TV, on-demand videos and video blogging anywhere.

    At the show, a two-wheeled, self-balancing electric vehicle carrying a camera and a laptop showcases real-time TD-LTE performance on the move. Live video captured by the moving camera can be viewed on other laptops and the main screen within the demonstration area via a TD-LTE USB dongle. Visitors are able to set up a video stream session between the laptop on the vehicle and the laptops within the demonstration area.

    The company informed that they will also integrate and launch the TD-LTE USB dongle that supports 2.3GHz at the event.

    According to Motorola, interest in TD-LTE continues to grow due to several key factors:

    • The tremendous growth of data use while mobile falling prices, more variety and improved ease of use in end user devices
    • Additional spectrum is necessary for serving more users
    • TDD spectrum traditionally auctioned for lower cost/radio frequency/population
    • Global and local roaming between FDD and TDD networks, allowing both networks to be used in the same geographic area.

    In effect, this ability to roam between FDD LTE and TD-LTE means operators can use TD-LTE networks to augment their FDD LTE network for more capacity or other applications such as video broadcasting, while operators choosing to use TD-LTE as their "main" network can still offer their subscribers the ability to roam to other operators’ FDD LTE networks in different countries.

    "We see the growing interest in TD-LTE as the technology delivers increased capacity and a lower cost per bit. Motorola is the leader in TD-LTE through trials and engagements with various operators around the world. The selection by China Mobile today once again demonstrates the reliability and maturity of our TD-LTE solution," said Dr. Mohammad Akhtar, corporate vice president and general manager, Motorola Networks business in Asia Pacific.

    “TD-LTE is now a commercial reality, making LTE a truly encompassing global technology standard,” he added.

  • Motorola Accelerates TD-LTE Commercialization with Success in Trials

    Motorola announced successful completion of its joint Over-the-Air (OTA) trial with operators as part of the collaborative Time Division Duplex Long-Term Evolution (TD-LTE) commercialization.

    According to Motorola, its key trial achievements include:
    • First company to complete download throughput up to 70 megabits per second (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).

    Motorola’s LTE solution is comprised of its OFDM broadband platform and a selection of radio options that include MIMO and smart antennas as well as its self-organizing network (SON) solution. The portfolio includes frame based-mounted radios, remote radio heads and tower top radios to support a variety of LTE deployment scenarios.

    In addition to the collaborative trials with operators, Motorola is also 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’s Wireless Broadband Access Solutions (WBAS) Hangzhou team and Wideband Base Transceiver Systems (WBTS) China team have been working with Chinese operators for many years to get TD-LTE closer to market reality in China.

    “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 of Motorola China.

    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 2×2 Multiple Input Multiple Output (MIMO).

    “LTE is the next big technology in wireless networking and incorporates several key technologies such as smart antenna, all IP and OFDM to enable operators to deliver rich, high bandwidth, multimedia services,” said Sudhakar Ramakrishna, corporate vice president of Motorola.

    Earlier this year, Motorola deployed a live 700MHz LTE demonstration network in Las Vegas, replicating the successful 2.6GHz live LTE experience in Barcelona. During these two drive tours, visitors were driven around the streets to experience the performance of LTE in a real-life metropolitan RF environment.
