Aprisa SR Product Roadmap [COMPANY INTERNAL] May 2012 Aprisa SR: summary of recent updates (1 of 2) 2 Feature What is it? Benefits and KSP Released / scheduled Access request/ access grant channel access mode A new method to control the traffic and how the network shares a common access channel Enhanced performance in SCADA systems; Contention free access; Improved throughput DELIVERED Q4, 2011 Network status overview Enhancements to SuperVisor that provides a single page network health status, with the ability to drill down to investigate problems A single page snapshot of network status; Displays vital information without the expense of a higher order SNMP NMS; Ability to ‘drill down’ into issues reduces fault resolution time Terminal server Provides the ability to transport IP over serial, or serial over IP Enables the customer to terminate serial data on the LAN at the base station – ease of integration with head end systems; Removes the need for additional third party equipment Over-the-air software upgrades Remotely update firmware on the entire network, managed from the base station No longer require ‘truck rolls’ to update the firmware; ‘Non-intrusive’ distribution mechanism minimises disruption to customer traffic while distributing new firmware © 2012 4RF Limited | COMPANY INTERNAL DELIVERED Q4, 2011 DELIVERED Q4, 2011 DELIVERED Q4, 2011 Aprisa SR: summary of recent updates (2 of 2) Feature What is it? Benefits and KSP Released / scheduled Multiple repeater support Supports multiple one-hop repeaters when using the Access request / access grant channel access mode Improved repeater performance to extend coverage or overcome path obstructions; Multiple one hop repeaters are supported throughout the network; Repeaters can support an RTU DELIVERED Q2, 2012 Updated protected station hardware improves operation New design provides a more robust switching mechanism; Improved protection of the protection switch itself DELIVERED April 2012 New Protected Station 3 © 2012 4RF Limited | COMPANY INTERNAL 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 Q3, 2012 Feature 4 © 2012 4RF Limited | COMPANY INTERNAL Aprisa SR: summary of new features (2) 5 Feature What is it? Benefits and KSP Released / scheduled Layer 3 filtering Filter IP traffic at layer 3 Improves network efficiency, reduces the traffic across the air Q1, 2013 SNMPv3 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 Q1, 2013 SNMPv3 encryption Extends SNMPv3 support by adding encryption Takes SNMP to the next level by adding encryption to the SNMP communications Q3, 2013 © 2012 4RF Limited | COMPANY INTERNAL 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 6 © 2012 4RF Limited | COMPANY INTERNAL 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 7 © 2012 4RF Limited | COMPANY INTERNAL 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 8 © 2012 4RF Limited | COMPANY INTERNAL 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. 9 © 2012 4RF Limited | COMPANY INTERNAL 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) 10 © 2012 4RF Limited | COMPANY INTERNAL 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. 11 © 2012 4RF Limited | COMPANY INTERNAL 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 12 © 2012 4RF Limited | COMPANY INTERNAL Thank you
