5G


ATDI is 5G ready.

Whatever standards are finally applied to 5G, ATDI software will work with them.

ATDI, its expert engineers and its systems are prepared for 5G and all future technologies

 

Overview

ATDI’s software has been technologically agnostic throughout the company’s history. From 2G to 5G, ATDI has been at the forefront of planning and modeling for three decades. That will continue to be the case when standards for 5G are finally agreed – no matter what those standards turn out to be.

Tools such as ICS telecom EV will continue to give network operators unparalleled degrees of precision for the next generation of radiocommunications and beyond.

ICS telecom EV is a mobile network planning solution which combines network planning, optimisation 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 optimisation
• Automated frequency planning
• Refarming frequency bands and inter-system coexistence
• Transport (microwave) planning

 

Case: Dynamic Carrier Aggregation

Challenge

Dynamic Carrier Aggregation (CA) is a mechanism used to increase user and system throughput. Aggregation of licensed and unlicensed bands provides a means of increasing available bandwidth in 5G networks.

Solution

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

Case: 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 higher frequencies, coverage planning techniques will differ radically 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.

Case: High-band 5G New Radio (NR)

Challenge

In 5G, New Radio (NR) cells act as the slave to LTE eNB. When operating in non-standalone mode, the connection will be anchored to LTE-mode, while 5G NR carriers are used to boost data-rates and reduce latency. Signalling 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 relies on a population of LTE users with profiles and traffic demands defined. This resolves the issue of traffic network congestion (or low traffic QoS performance) by adding new high- band 5G New Radio (NR) sites in the not-spot area to boost data-rates and reduce latency. This function considers DL/UL coverage criterions and traffic assumptions.
