eLTE-U solution uses TDD LTE access technologies based on Wi-Fi spectrums. High LTE network performance and easy deployment of the Wi-Fi technology enable the eLTE-U solution to have a longer coverage distance, stronger anti-interference capability, stronger mobility, larger user capacity, and higher security and reliability than the Wi-Fi and microwave technologies.

The eLTE-U solution provides industrial professional users with industry-grade stable and reliable wireless connections for video surveillance of public safety, automated port operations, and data backhaul of production campuses.

The standard organization MulteFire Alliance (website: https://www.multefire.org/) aims to apply LTE technologies to Wi-Fi spectrums. As a member of this organization, Huawei launches the eLTE solution and becomes the first company that applies MulteFire technologies in the markets.

Reliable Connection on Unlicensed Spectrum

  • 2.4 GHz/5GHz Spectrum, subject to regulatory demand
  • Advanced anti-interference technology
  • Higher Security than Wi-Fi with enabling bidirectional authentication between terminals and base station
  • Inter Cell Interference Coordination (ICIC) reduces cell interference, elevates cell-edge rate.
  • Interference Rejection Combining (IRC) improves uplink signal quality, reduces terminal interference.

Longer Coverage Distance

  • High receive sensitivity enlarges coverage 2 to 3 times versus Wi-Fi.
  • DL Power-boosting promotes downlink coverage.

High Performance

  • 50 ms latency and zero packet loss meet industry control requirements
  • Comprehensive 9 QoS level guarantees first priority of industry control.
  • More concurrent online users

Better Mobility

  • Up to 160km/h high speed, robust mechanism ensures no service interruption during handover.

Enterprise Campus

  • Manufacturing campus: The production network bears security data, requiring high reliability and low data rate.
  • Full substation coverage: A typical 220-kV substation covers an area of 90,000 m2. The network needs to provide seamless coverage to support the automatic preventive maintenance inspection (PMI) service. To meet secure production requirements, wireless devices can be deployed only in main control buildings at the four corners of the substation.

Transportation

  • Train-to-ground connections of the metro: Train-to-ground connections support uplink data transmission of compartment video surveillance, and backhaul of video surveillance data of 14 cameras in the six-compartment train.
    Train-to-ground connections support downlink PIS and network surfing services. A bandwidth of 8 Mbit/s is required for the PIS service. A bandwidth of 80 Mbit/s is required for network surfing when there are 500 passengers.
  • Railway crossing monitoring: If there is no crossing monitoring, the driver must be able to observe the situation of the crossing before the safe brake distance. The driver must perform emergency braking once finding that people or animals intrude the crossing.
  • Full port coverage: The berth area is deployed with a lot of cameras and is severely blocked by metals. The port has a large container yard with long aisles. The Base station can be installed only in the lighthouse of the port.

Others

  • Network surfing in rural areas: Transmission resources are unavailable in remote areas. The wired transmission costs a lot. The wireless solution is required. Common terminals connect to the network in the Wi-Fi mode in the last 100 meters.
