Why Mission Critical?
Failure is not an Option: Peoples Lives, Property,
Communities and the Economy is at Stake
Radio Data NetworksCopyright Radio Data Networks Limited 2018
4 - Communication Modes
Voice:
Commands and Assistance
Information
Human to Human Data:
Messages – SMS & SDS, etc
Machine to Human Data
Automated SMS/SDS and Voice
Machine to Machine M2M
Measurement Data - Telemetry
Real-Time Control
Automated Staff Gauge

Why Cellular Falls Short of Being Mission Critical
Base stations have typically only 4-
hours backup when power is lost
Limited Capacity in Rural Locations
unable to cope with Emergency
Traffic
Coverage Optimised for Population
rather the Land Mass – Revenue
Driven
Software PTT exists but requires a
remote data servers – therefore
delays and Less reliable

Shortfalls of Cellular Telemetry & Data
Obsolescence Threatens Asset Life and
Investment 2G & 3G to 4G > 5G Migration
No Heart Beat
Poor Penetration into Buildings Basements,
Culverts, River Banks, Through Forests, in
Cuttings
SIM Cards prevent devices from being
100% sealed
Wakeup and Registration can take 2-
Minutes before data can be sent – eats
batteries and can be too late!

Mission Criticality of Standard IoT
Licence Free Radio – sharing same spectrum
No SLA – No assurance of data delivery.
Responsibility Chain – Who to blame
Minimal Testability – if it doesn’t work what do you do?
No Support for Real-Time Control – Data must go via Internet
Data Ownership / Legal Status Unresolved !
Denial of Service / Jamming not Illegal – Jammers Available
Limited messages – LoRa, Sigfox as little as 84 messages per day
Open Standards – Make Hacking Easier
Low Cost (KPN) €5 per year = Low level of service - Low Valve
