Aprisa SR: summary of new features
What is it?
Benefits and KSP
Released /
scheduled
Over-the-air rekeying
Change the encryption key
over-the-air for the entire
network
Continually changing the security key
increases security;
Over-the-air re-keying eliminates ‘truck rolls’,
enables frequent key changes;
Easily managed via SuperVisor
Q3, 2012
Repeater/remote
protected station
Repeater and remote
stations can be configured as
a protected station
Provides a redundancy option for key
outstation and repeater sites
Q3, 2012
Enhanced overthe-air
compression
Applying compression
techniques to the over-the-air
traffic reduces the overhead
of Ethernet packets
Increases throughput by significantly
reducing the Ethernet overhead, enabling
more Ethernet RTUs to be connected to a
network
Q3, 2012
Single
management of
protected station
Provides a mechanism to
mange the protected station
as a single entity, rather than
logging into the radios
separately
Simplifies management of the protected
station

Supports the v3 SNMP
standard with security to
network management
functions
Security functionality included in SNMPv3
provides an extra layer of security for
network management systems

Aprisa SR roadmap: OTA re-keying
Provides the ability to change security
keys remotely throughout the network
Managed through new ‘security’ menu
item in SuperVisor
•
‘Manager’ page for key management
•
‘Distribution’ page for key distribution
Follows the same process as OTA
software upgrades

OTA re-keying: what this means to the customer
• Continually changing security keys increases security
• OTA re-keying makes this process simpler
• Eliminates the need for ‘truck rolls’
• Customers are more likely to regularly change their security keys

Aprisa SR roadmap: simple management of the protected station
Manage both radios through one SuperVisor
session, simple user interface
Log into either radio IP address
Configuration details of both radios shown in
single view
Changes common to both radios are shown
as a single box and changed on both radios,
automatically
For radio specific parameters, Primary radio
is shown on the left and Secondary radio on
the right
Benefit: Managing the protected station is
much simpler

Aprisa SR: compression background
With the move to IP based RTUs, the traffic over the air is significantly
increasing, reducing the number of Ethernet RTUs that can be supported
in a single network,
This is turn means more base station sites, which translates to increased
costs for customers to add new points of presence,
It is not the Ethernet based SCADA protocols causing the increased
traffic, but the Ethernet headers wrapped around the protocol and
standard Ethernet operation (TCP and UDP),
Compression techniques can significantly reduce the Ethernet header
overhead by removing information before transmitting and recreating it at
the other end, a learning process,
In examples with Iberdrola, the number of remotes jumped from 14
remotes without compression to 22 with compression.

Aprisa SR: compression details
Compression provides significant improvements
Over the air (OTA) packet length for serial data is typically 28 bytes for a ‘poll’ message:
• 6 bytes of Data
• 22 bytes of Radio
For a 6 byte IEC 104 ‘test frame’ carried as IP the OTA packet length is 86 bytes.
Compression reduces this to 26 bytes
Compression techniques:
• Radio Network and Ethernet – Proprietary
• TCP/IP ROHC v2 (Robust Header Compression v2. RFC4995, RFC5225, RFC4996)

Looking to the future
Customers are seeking to monitor more points
in their network.
Additional services are being investigated to
be added to the telemetry network.
Small set of specific combinations of IEC
60870-5-104 protocol settings and topologies
can stretch existing capabilities.
The meet these demands, building on the
excellent base of the Aprisa SR, the Aprisa
SR+ is being developed, with increased
capacity and functions to further strengthen
the 4RF point-to-multipoint offering.

The next generation
Highest capacity in the market, delivering over 120 kbps of gross data, using QAM
modulation techniques for speed and robustness
Adaptive modulation and automatic transmit power control ensures the maximum
bandwidth is provided in the ever changing RF environment
High power – 10W PA design ensures optimal coverage through all modulation types
