3D Models Development Technology for Wireless Networks Planning and Optimization

Communication’s quality and additional services range, costs reducing, possibility of rapid project realization directly depends on quality of initial planning and optimization of the existing network, which is connected directly to accuracy and detailing of region’s model, which can be achieved only using 3D models.

According to market researches, market demands for 3D models is expected to grow constantly, because of fast spreading of new technologies like 3G/4G/WiMax/LTE.

For example: as for February 2012 – 91 wireless operators started deployment of LTE networks in 53 countries.

There are several factors which are affecting on necessity and ability of 3D data in 3G/WiMax/LTE networks planning, such as:

  • Growing of networks density. Distance between base stations, having been approximately 0.5-1km in recent past, now is close to 200-300m. LTE networks in many countries is planned to use frequency 2.6GHz, and such frequency also cause reducing of range between base stations because of technical requirements. For such high-density networks planning and optimization, operators need high-accuracy 3D geodata.
  • Propagation models became so accurate that they can simulate signal propagation with high accuracy in the urban area taking in to account height and configuration of every single building, vegetation block and other obstacles. Initial data for such models is 3D geodata.
  • Accessibility of high accuracy satellite images (with resolution 0.5m and higher) – main data sources for 3D models producing.
  • Present planning tools possess high potential for high accuracy data processing.
