5G NB-IoT NTN service with GEO satellite operators

Let us present: 5G NB-IoT for GEO! GateHouse SatCom looks into the possibilities of making a 5G NB-IoT NTN service with GEO satellite operators.

Some of the benefits:

  • High-volume terminal market
  • Low-cost chipsets equal easy access for terminal manufacturers
  • Available for end-users directly through a GEO satellite operator or MNO (Mobile Network Operator)
  • Hybrid TN and NTN systems
  • MNOs are expected to drive growth in the market by extending coverage through satellite connections – 3GPP standardization will ensure compatibility of the chipsets
  • Reuse GEO satellite operator’s existing satellites

GEO 5G NB-IoT TN/NTN Network overview

Technology is constantly evolving. 3GPP is introducing the Non-Terrestrial Network in the 5G standardization which will lead to true global coverage for IoT devices as the standardization will ensure compatibility of the chipsets.

Multiple simulations on GEO systems and analyses have proven that technology from mobile networks works over GEO satellites with little or no modification and will provide a cost-effective path to hybrid, dual-mode global NB-IoT coverage.

3GPP collaboration

GateHouse is a full member of 3GPP, and we actively contribute to 3GPP’s standardization for non-terrestrial networks with the aim of establishing 5G standards towards new use cases and services for satellite communication networks. We are very committed to the standardization work; we are expert advisors using our knowledge of satellite communication to contribute to form the standard.

We have been working with feasibility studies for various GEO solutions, and for long, we have been further developing the NB-IoT solutions, and in 2021, we started developing GEO solutions for New Radio as well.

Timeline: Pre-assessment-Feasibility-Pilot-project

Pre-assessment, Feasibility and Pilot Project: Timeline

Pre-assessment

Duration: 1 month

  • Studies to qualify if the satcom system is applicable in a 5G context
  • Initiated studies indicate that the project is realistic and realizable.

Feasibility

Duration: 6 months

  • Thorough study on all frequency bands (L-, S-, Ku-, Ka-bands)
  • Optimization of resource utilization for the GEO satellites
  • Obtainable capacity
  • Optimization of 3GPP standards for better capacity and resource utilization

Pilot project

Duration: 9 months

  • Implementation of satcom system
  • Integration tests
  • Demo case on strategic customer in collaboration with satellite operator
  • Preparation for commercial phase

Commercial

Duration: 3 months

  • The project enters the commercial phase with a wide usage

Until the beginning of 2024, the UE will be based on 3GPP Release 17, and thereafter on Release 18.
3GPP Release 17, UE end of 2022
3GPP Release 18, UE beginning of 2024

Global-Reach_Active Beams

GEO satellite with 100 active channels

Assuming that the total capacity of the satellite is used only for NB-IoT, there will be 345 M transactions per satellite per day:

  • 40 small transactions per second per channel (100 bit)
  • 100 active channels

=> 40*3600*24*100 ~ 345 M transactions per day per satellite
(GateHouse estimate based on specs for one GEO satellite on the L/S-Band, one channel at a time)
Equals 69% of the estimated market in year 2030.

Tech specs

A series of comprehensive studies carried out by GateHouse indicate that the link budget is reasonable and that it is realistic to move further with the project on 5G NB-IoT for geostationary (GEO) satellites.

Realistic?

  • Multiple simulations on GEO systems and analyses indicate that the project is realistic
  • Take into account that more satellites are needed to cover all areas.

Requirements to realization

  • Requires smart control of beams and carriers to utilize resources and optimize service (eNodeB)
  • Requires scalable NodeB tailored satellite system

Perspective

  • 3GPP air interface and protocols can be enhanced to utilize resources efficiently for Inmarsat satellites – and also for devices (e.g. lower power consumption)
  • Terrestrial network (TN) chipsets can be reused and work in dual-mode
  • Can integrate with Satellite Operator Core network or other MNOs
  • Expansion options towards other 5G waveforms e.g. LTE-M and New Radio
  • Current estimates suggest a price of 1 EUR per device per month equals 345/4 = 86 M devices connects 4 times per day, equals a yearly ARR of 1 BEUR.
  • TAM estimated at 6 BEUR (1EUR/device/month*12 months *500 M devices = 6 BEUR)
    (Ericsson mobility report & NSR predicts a market of 500 M devices)
GEO System Architecture

5G in GEO system setup

Get started with your 5G project in collaboration with GateHouse. Based on your data, we suggest how to build a system. With many years of experience within NB-IoT, we can help you decide whether your system is suitable for 5G.

Feasibitlity study:

5G for GEO_feasibility project

How it works

To build a system model, we use the input, information, and ideas from our customer such as:

  • Link budget parameters
  • System parameters
  • Antenna conditions
  • Expected number of UTs
  • Data rates

Based on this information, we use our knowledge about IoT systems, inhouse resources, and experience to build a system model and create simulations in MATLAB that can help decide if the customer’s system is suited for 5G.

Set up a business case

The feasibility study is an easy and cost-efficient way for customers to get started:

  • Predetermined project
  • Fixed fee
  • Set period of time
  • Non-binding
  • No obligations

The elaborate study can help validate your 5G or 5G NB-IoT plans with no obligations. You will get a report with recommendations that can help form the basis of your decision.

Simulation examples

 A comprehensive MATLAB simulation environment has been built to facilitate NB-IoT system design and feasibility analyses.
Below, you find examples of the different simulations that GateHouse can help generate in order to determine whether your system is suitable for 5G applications.
