ICS telecom EV models 5G networks including different architectures and combinations of bands and bandwidths

ICS telecom EV is a mobile network planning solution which combines network planning, optimization and functionality
developed specifically for future  technologies. These advanced features include:

  • Carrier aggregation simulations
  • mmWave coverage planning
  • Coverage planning (2D/3D)
  • Interference calculations
  • Capacity planning (DL/UL throughput)
  • Traffic analysis
  • Monte Carlo simulations
  • Automated site planning
  • Automated site optimization
  • Automated frequency planning
  • Re-farming frequency bands and inter-system coexistence
  • Transport (microwave) planning
Dynamic Carrier Aggregation

Challenge

Dynamic Carrier Aggregation (CA) is a key mechanism used to increase user and system throughput. Aggregation of licensed and unlicensed bands enables the network operator to increase available bandwidths for 5G networks.

Solution

ICS telecom EV supports carrier aggregation for both FDD and TDD modes. The modeling of the network is composed of several layers. For example, a mix of stations operating in the 2600 MHz with 20 MHz bandwidth and 1800 MHz with 10 MHz bandwidth etc in the same project. Aggregated throughputs are calculated by summing the volume of data from each serving cell included in carrier aggregation. This engine enables the user to perform a global analysis of the throughput (comparison, sum, overlapping, etc.) between the different layers.

Air interfaces based on mmWaves coexistence with LTE networks

Challenge

Air interfaces based on mmWaves coexist with existing LTE networks in carrier aggregation mode. Future 5G network deployment scenarios will facilitate high data rates over short distances.

Solution

At high frequencies, coverage planning techniques will be radically different from those used today. Diffraction losses become so high that there is an almost binary switch between ‘served’ and ‘unserved’ areas, as shadowing by environmental clutter interrupts the line-of-sight between base station and user. Using generic propagation models, mmWave stations can be computed at the same time as VHF/UHF and SHF stations in ICS telecom EV.

High-band 5G New Radio (NR)

Challenge

In 5G, New Radio (NR) cells act as the slave to LTE eNB. In non-standalone mode, the connection will be anchored in LTE-mode, while 5G NR cells are used to boost data-rates and reduce latency. Signalization and user-traffic will be distributed in different frequency bands.

Solution

ICS telecom EV features a ‘prospective planning’ function which identifies the best locations for master low-band LTE sites. This function is based on coverage target assumptions for signalling capabilities. The ‘parenting LTE’ function is based on a population of LTE users, with profiles and traffic demands defined. This feature resolves the issue of traffic network congestion (or low traffic QoS performance) by adding new high-band 5G New Radio (NR) sites in the hot spot area to boost data-rates and reduce latency. This function takes into account DL/UL coverage criteria and traffic assumptions.
