1. LTE for Railways
Long-Term Evolution (LTE) is a standard for high-speed wireless
communication - high speed, high security, and high bandwidth capacity
One LTE network infrastructure for value added services
> On-Board CCTV
> On-Board Passenger Information System
> Telemetry of on-board condition monitoring sensors
> Telemetry of wayside sensors
Industry standard network elements
LTE network
components are COTS
standard and not
railway specific lowering
CAPEX and OPEX
Strong ecosystem
support with terminals
based on 3GPP
standards
LTE has a legacy of
422 networks in
143 countries
3GPP release 13

2. ONBOARD Connectivity
Onboard Connectivity
Provides passengers with
connectivity inside trains

Base: Brazil Smartphone Commuters
The transport industry lags behind
in providing:
> Uninterrupted connectivity - underground, and
while commuting
> Real time and integrated information across
modes
> Unified and smart ticketing across modes,
parking and tolls
> Real time crowd information – platforms and on
metros

Reliability
(e.g. on time)
The perception is that mobile providers are
responsible for poor connectivity when
commuters are in cars/taxi, but the public
transport industry is responsible when they are
on buses/metro/trains
WIFI onboard solution› Enabling different communications networks to work
in parallel
› Seamlessly combining different technologies into a
“hybrid” solution
› Always-online experience to end users and
applications
› For the customer this means never being locked into
a specific technology or bound by a single
communication supplier’s pricing.

4. IoT for Rail
– Very advanced sensors - Expensive & complex to repair
– Expensive sensors - 3,000 to 70,000 SEK
– Wired solutions - Cables everywhere & expensive installations
– Costly recourses - Expensive and waste on travel time
– Reactive approach - Data is gathered after the outage
Today train manufacturers and others are using
– Simple sensors with less logic - “The brain” located centrally
– Wireless Solution - Reduced price on installation
– Better Services - Predictability will save $$$
– Less outages - Fix the problem before it causes too big problems
– Support on competitor equipment - After mounted sensors
A game changer will be
It will be A game changer!
