SIMLAB.SPACE provides performance estimations for the satellites operating on 5G NB-IoT NTN technology.

Satellites have long been used for providing connectivity, while the demand for the IoT market increases every year. The recent technological advances within satellite software aim to support the 5G connectivity between satellites and IoT devices. The advantages of the new 5G NB-IoT NTN standards being in the ability to connect satellites with IoT devices that require little data, a long-lasting battery, and a low price, plus enhancing a high number of items, and wide coverage area. All these factors, place SatCom in front of terrestrial networks when it comes to IoT connectivity. At the same time opening new business opportunities for satellite operators.

The Importance of Satellite Simulations

The low Earth orbit satellites are growing in number, but flying one and connecting it to IoT devices can be a real technological challenge. Therefore, it is paramount to predict the behavior of LEO satellites in certain settings. A satellite simulator is an indispensable tool for modeling and evaluating the capacity of a satellite. Thus, contributing to more effective development, analysis, and troubleshooting of a satellite. Plus, having a better command of coverage area and data transmitted by each IoT device.

A satellite simulator allows users to investigate key metrics driving a successful satellite operation and furthermore adapt or modify certain parameters to meet the customers’ needs and requirements. Currently, the satellite simulator market is limited when it comes to measuring the performance of satellites supporting the new 5G NB-IoT NTN technology.

SIMLAB.SPACE comes to solve this challenge by providing affordable and accessible service in the cloud that configures, runs, and analyzes a simulation estimating the 5G connectivity of low orbit satellites and IoT devices.

SIMLAB.SPACE performs a simulation by following three steps: configuration, simulation, and results from delivery.

1. Configuring a Simulation

The step of configuring a simulation involves setting up the following parameters.

Campaign data:
 –  Duration
 –  Step
 –  StartTime

Satellites data:
 –  Orbit
 –  Radio (Power & Frequency)
 –  Antenna data

IoT device data:
 –  Location (Latitude & Longitude)
 –  Ground device Radio
 –  Devices Antenna parameters

2. Running a Simulation

At this stage, the stimulator measures satellites’ performance in terms of
 –  Coverage
 –  Connectivity
 –  Bandwidth

3. Analyzing a Simulation

Tracing the activity of a single satellite or IoT device and aggregating key performance indicators including:

 –  Data sessions generated
 –  Data sessions completed
 –  Data session success rate
 –  Data transmitted
 –  Average session completion time
 –  Average user bitrate
 –  Average coding factor
 –  Average buffer size
