Fixed-broadband subscriptions per 100 inhabitants

More than 50 countries have less than 1% Fixed Broadband subscriptions over

the total population

•Difficult terrain: Mountains, desert, snow andice, restricted or protected areas.

•Access to the premises: no ducts available, orthey are fully occupied. Particularly in theaccess to the end user premises

•In building cabling: Old buildings and historicalareas present issues when laying fiber

•Civil works: Aerial and façade cabling notallowed to deploy. Trenching; road openingpermissions… slow, if not unfeasible andextremely costly.

•Rural areas: Lack of business case thatdiscriminate the citizens in such zones (digitalgap)

THE CHALLENGE: FIBER DEPLOYMENTS

THE SOLUTION: HOW IT WORKS

COMPARATIVE WITH 5G

Key parameter 5G Requirements (ITU) SistemGoAir

Peak data rate 20 Gbps 20 Gbps

Speed perceived by the user 100 Mbps Up to 800 Mbps

Spectral efficiency >1.5 bps/Hz 4.70 to 6.25 bps/Hz

Maximum latency 4 ms <1ms DS; <4 ms US

WAIT… WHERE IS MY BACKHAULING?

In many locations it is impossible to findbackhauling to the backbone

Backhauling is extremely expensive

No International Internet Connectivity

PROJECT IS NOT FEASIBLE

THE QUESTION: SATELLITE?

Business Case: Is satellite a solution for Backhauling?

What will be the new developments in satelliteconnectivity?

LEO constellations?

VHTS?

What is the added value of the Fixed Wireless Accesssolution?:

Bigger antennas for SATCOM backhaul placed in the base stations with higher efficiency modulations

High efficiency Cost reduction

BUSINESS CASETaking into consideration the following assumptions:

The average monthly consumption for a fixed broadband user is of 40 Gbytes. We will also consider a case for 20 Gbytes monthly consumption.

From this amount, 15% is consumed during the peak hour. During the peak hour 70% users are connected.

With an ARPU (Average Revenue Per User) of 50 Eur, we consider two cases: 20% and 30% destined to Satellite OPEX.

With the above assumptions the required Mbps during the peak hour and the OPEX dedicated to satellite would be the ones reflected in the graphs:

500 users 40 Gbytes/month - 20% Satellite OPEX 156 Mbps -5000 Eur 32 Euros / Mbps

500 users 20 Gbytes/month - 30% Satellite OPEX 78 Mbps -7500 Eur 96 Euros / Mbps

Data traffic assumptions taken from Top Optimized Technologies plus other, internal Inster.

Reduce cost with higher efficiency?

CONCLUSIONS

There is a huge digital gap in the world. We are here to solve it.

In many cases fiber is not the solution Use Fixed Wireless Access Solution.

The problem is the backhauling, many times inexistent or expensive. Projectis not feasible.

Possibility of using satellite as backhauling.

OUR GOAL IS TO FIND SOLUTIONS, TOGETHER WITH THE SATELLITE INDUSTRY, TO MAKE SATELLITE BACKHAULING A

REALITY FOR FIXED WIRELESS ACCESS
