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

Essentials for Mission Critical

Communications?

Triple Nines Reliability – 99.9% Up-Time

Capacity to Cope With Incidents

Rapid Dispatch – Peer to Peer, Groups

Work Everywhere, Indoors and Out

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

Radio Data Networks – Introduction 2017Copyright Radio Data Networks Limited 2017

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

Licenced Telemetry / Mission Critical IoT

Cyber Secure – Private Licenced Radio – Non-IP Based

Legally Protected Service - Wireless & Telegraphy Act

Battery Efficient Communication Protocols

One Way or Two Way Control Networks

2 to 5 - Minute Health Messages

Broadcast Mode Operation – Multiple Receivers

Direct Interface with 3rd Party Networks

Tetra SDS, Satellite SBD, IP, Relays, 4-20mA
