MassiveMIMO

  • With 5G approaching, mobile broadband applications, especially online video applications develops quickly, which brings huge challenges to operator network evolution. Therefore how to improve capacity with current limited spectrum resources to support high throughput applications becomes a vital task for operators. In addition, with the rapid urbanization development, insufficient signal coverage in high-rise buildings also becomes another common problem affecting network quality.
  • Traditional coverage solutions have common problems:
    1. For buildings above 10 levels, hard to deploy indoor coverage solution, therefore difficult to improve coverage and capacity
    2. Mobile data explosion, while new site acquisition is hard and costs much
    3. Limited uplink capacity and coverage

    ZTE innovative Massive MIMO solution, can provide up to 8 times capacity boost with current spectrum resources, significantly improves network performance.
