  6. 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

  7. 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

  8. 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

  9. 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.

  10. 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)

  11. 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.

  12. 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
