Application agnostic, providing the opportunity
to revolutionize, differentiate and create
Promotes interoperability and mass
deployment
Allows smooth porting of value-creating
applications on every mobile-edge server,
with guaranteed SLA
The vast majority of the population can be
served
MEC scope focuses on
enabling third-party
applications to be hosted
in the mobile network
edge.

V2V is about proximity, path prediction
and collision anticipation/warning:
• Intersection & Lane Change
• Rear end

Innovation and benefits of Nokia’s MEC Server
Direct communication between vehicles and as well
as between vehicles and cloud over cellular
(LTE – short, mid and Long Range)
MEC
Server
• LTE base stations along the motorway are
equipped with Nokia’s Edge IT server (the central
cloud is extended by “edge cloudlets”)
• Vehicles can communicate with very low latency
(< 50ms) over distance from 10m to >2000m and
more: e.g. used for hazard warnings
• LTE is or will soon be available with full coverage
in most countries
• Investment of enhancing LTE with MEC cloudlets
is substantially less than building new ITS G5
roadside infrastructure in particular in rural areas

DENM: Decentralized Environmental Notification Message
=> low latency / large sector requirements
• Slow or stationary vehicle
• Obstacle on the road
• Wrong-way driver
• Emergency electronic brake lights (EEBL)
• Adverse weather condition
Monitoring of surrounding vehicles
CAM: Cooperative Awareness Message
=> low latency / “not-visible” area requirements
• Intersection collision warning
• Longitudinal collision risk warning
• Blind spot assistance
MEC can provide
ultra-low latency networks
to avoid collisions and dangers
