Smart radio for smart networks
1 The need for future-proofingUtilities today face unprecedented change and distribution network operators(DNOs) have both the responsibility and requirement to prepare for thechallenges of the smart grid. These include increasing demand, distributedgeneration, environmental concerns, peak management, security and morestringent regulations. Infrastructure investment must also meet the tests offiscal responsibility, an important component of which is ensuring thesuitability of such investments for the long term.
The investment challenge is further complicated by the lack of consensus as tothe precise nature of the future landscape. Standing still and waiting forclarity is not an option due to the time required to select and deploy network-wide infrastructure and the imperative to quickly realise the performancegains demanded by regulators and, perhaps more importantly, the balancesheet. A future-proof investment policy is needed, where infrastructure:
Is dimensioned for today’s needs yet scalable to meet tomorrow’s
Addresses both commercial pressures and operational realities todeliver the most effective performance and efficiency improvements
Takes into account the context of long term, multi-stakeholder assetmanagement plans and capital investment cycles that require networkequipment to be deployed for 20-30 years or longer
A changing world
A key example of how the utilityworld is changing is the transition toIP. It is now generally accepted evenwithin the utility world that IP is acase of when not if. However, howcan you manage a gradual transitionto a world of IP? Also, while theinteroperability advantages of theopen standard are clear, how can thesecurity implications be adequatelyaddressed?
“We only want to purchase equipmentonce, for the long term, but we don’tknow what tomorrow’s needs willbe…”
“Commercial pressures mean we needto invest now but we cannotconstantly visit sites to upgradeequipment as requirements change…”
“We want to be ready for an IP worldto avoid equipment replacement ortwo networks, but we don’t want tohave to over-spend to over-provisionnow…”

Smart radio for smart networks
2 Future-proof SCADA communicationsFor DNOs and integrated utilities alike, the investment priority is clear. Whileindustry forums resound with talk of renewable energy sources, electricvehicles, AMR and peak shaving, it is widely accepted that the most immediateand substantial returns are to be found by increasing visibility and control ofthe distribution network through the deployment of more and better SCADAequipment. Furthermore, it is in deploying the communications networksrequired to support these SCADA deployments that utilities have the mostobvious opportunity to make smart, future-proof investments.
How can a communications platform address both commercial and operationalconcerns and provide such a future-proof investment? The Aprisa SR smartpoint-to-multipoint radio does this by ensuring that it provides the followingthree things:
A single, scalable, upgradeable network
Equipment designed for longevity
Comprehensive, upgradeable security measures

A technical legacy
Combined, transmission anddistribution networks represent asignificant technical legacy. It is notunusual for electricity utilities tohave infrastructure assets rangingfrom brand new to 80 years old.
“The Brattle Group says that NorthAmerica alone will require nearly $1trillion in new transmission anddistribution investment from 2008 to2030, not counting what will berequired to meet future climatechange rules. Other sources forecasteven higher numbers, especially forthe world as a whole. According tothe International Energy Agency (IEA),a cumulative $13 trillion is neededworldwide during that period, morethan half of that for the grid andrelated equipment (as opposed tonew or refurbished power plants).” [1]
According to a recent GTM Researchsurvey, distribution automation andgrid optimisation is the number onepriority for utilities. [2]

Smart radio for smart networks
2.1 ScalabilityA single, scaleable, upgradeable network means that your communicationsnetwork works for you, not the other way round. You transition from serial toIP at your own pace, with a mix in the network as required, and with acommunications solution that interoperates with both existing and newequipment. This avoids the situation of separate serial and IP networks forlegacy RTUs and new IEDs respectively, ripping out old serial communicationswhen you change to IP, or investing in IP capacity now throughout the networkdespite not needing it in the short term in many instances.
With such a network, you control when, where and how you scale yournetwork and deploy new units or add previously unmonitored assets. You payfor enhanced features and functionality as and when you need, rather thanhaving to pay upfront for a wide feature set that may or may not be what youneed in the future. You eliminate costly truck rolls and minimise maintenancecosts.
How can a communications platform achieve this? By providing a standards-based solution that gives you what you need now, with a software-basedevolution path. The Aprisa SR future-proof approach includes:
Support for both serial and IP protocols, with every element of thenetwork configured as serial, IP or both: IP capability can be addedwhen needed, rather than investing in this ability before it is needed
Software upgradeability for initiating licence keys for newfunctionality or installation of new software releases, implementedover-the-air from the network operations centre and eliminating theneed for site visits
Scalability, flexibility and network efficiency: adding to the networkas needs change, reconfiguring the network at the touch of a mouse,and optimising the network for maximum efficiency based on thenetwork topology
These future-proof features mean that you can invest in a communicationsnetwork that is dimensioned for your current needs yet scales easily and cost-effectively as the future landscape becomes clear and your needs evolve, forboth operational and commercial sense. A controlled rollout is enabledthrough software upgrades, not truck rolls.
A future-proof investment…
Is dimensioned for today’srequirements yet scalable tomeet tomorrow’s
Addresses both commercialpressures and operationalrealities to deliver the mosteffective performance andefficiency improvements
Takes into account the context oflong term, multi-stakeholderasset management plans andcapital investment cycles thatrequire network equipment to bedeployed for 20-30 years orlonger
Page 5 | SCADA communications | Future-proof your investment
Smart radio for smart networks
2.2 LongevityEquipment designed specifically for longevity means that your communicationsnetwork will stand the test of time. You can be reassured that the reducedmaintenance cost advantages of improved monitoring and control are noteliminated by having to spend time and money maintaining thecommunications network itself. You know that wherever you deploy theequipment, from high temperatures on overhead lines to freezing conditions,it will continue to operate. You know that you can plan and deploy yourcommunications infrastructure in line with lengthy budget cycles, confidentthat once deployed it will remain so for as long as you need it.
How can a communications platform achieve this? By providing equipment thathas been specifically designed to take into account the harsh conditions,lengthy deployments and dependability needed by utilities. The Aprisa SRfuture-proof approach includes:
Reliability: superior RF design guarantees both quality and quantity ofdata transmission, and from a physical perspective, attention todesign detail, comprehensive thermal testing and specialistmanufacturing ensure that equipment simply keeps on working
Robustness: a rugged enclosure and immunity to temperatureextremes means you can deploy your communications equipmentanywhere and everywhere, confident that it will withstand anyconditions
Resilience: with licensed frequency bands and a network that youown and operate, your communications network does not fall over ifthe local cellular network goes down
These future-proof features mean that you can invest in a communicationsnetwork that takes a total life cost approach, hardware longevity combinedwith software upgradeability. It will stand the test of time, both operationallyand commercially.
Longevity throughout the grid
“The speed of technology change inthe telecommunications market ishigh compared with utilitytechnology. Utilities expect asset lifeof up to 40 years. This exposesutilities to risk of obsolescence andassociated cost of maintainingobsolete technologies.” [4]
New technologies that can deliverlongevity and a future-proof approachenable utilities to maximise assetutilisation.

Smart radio for smart networks
2.3 SecurityComprehensive, upgradeable security measures mean that despite anunknown future, your communications network can embody relevant securitystandards and recommendations as they evolve. As governments andregulators continue to develop increasingly stringent requirements, you knowthat the communications equipment you deploy now will continue to have thebest security available. You know that you will not have to rip out hardwarebecause it fails to comply with easily predictable security regulations. You canbe reassured that despite the types and sources of cyber attack changing, yourcommunications network remains secure.
How can a communications platform achieve this? By providing a solution thatnot only embodies the best security available, but continues to do so into thefuture. The Aprisa SR future-proof approach includes:
Defence in depth approach to security: the utility world can no longerdepend on ‘security through obscurity’, and security is much morethan simple encryption or password protection. A comprehensiveapproach to security takes into account the types and sources ofattack, relevant security design standards and recommendations,network interfaces and security fundamentals
Upgradeability through software: security and securing networks areconstantly moving targets, with attacks and attackers constantlyevolving to meet the challenge of whatever measures are currentlyimplemented: Software upgradeability is essential, particularly forequipment that will be deployed for considerable periods of time, toensure that the latest standards and recommendations can beembodied without the need for site visits or hardware replacements
Absolute control: with security being such a vital element of utilitynetworks, SCADA and communications, owning your owncommunications infrastructure makes absolute sense. Why depend ona third party operator, who often has other commercial imperatives,to deliver a utility-specific communications network that will alwaysgive you the security you need?
These future-proof features mean that you can invest in a communicationsnetwork that takes security and evolving standards into account, ensuring thatyour critical infrastructure is safe and within your absolute control, both nowand into the future, while still making commercial sense by minimisingupgrade costs.
Cyber security
Cyber security is of ever-increasingconcern. The world as we know it ischanging. Cyber attacks are changingand utilities are moving from targetsof opportunity to targets of intent.
Vulnerabilities are being consideredat the very highest levels ofgovernment, with unfolding securitystandards and large nationaleconomic stimulus spending plans.While it is not known exactly howsecurity standards and requirementsare going to evolve, they are onlygoing to get more stringent.
The Stuxnet worm is only one of themore recent cyber attacks to havebeen widely publicised. By September2010, there were approximately100,000 infected hosts. [5] More thanhalf of the malicious software threatsthat have ever been identified wereidentified in 2009. [6]
Pike Research estimates thatworldwide smart grid cyber securityspending will reach over $1.7 billionin 2013. [7]

3 Future-proof consequencesChoosing a communications platform that provides you with a future-proofinvestment means:
A single network, deploying enhanced functionality as needed, ratherthan over-provisioning and over-paying on day one, despite theuncertainties of the future
Seamless rollout of the latest and most stringent security mechanismsacross your SCADA communications network
Reduced maintenance costs with equipment designed for the lengthydeployment periods that utility infrastructure demands
Most importantly, owning your own future-proof communications platformgives you absolute control over your network, from both a commercial and anoperational perspective, however long it is deployed for and whatever thefuture holds. When it comes to your critical infrastructure, a future-proofinvestment is not just smart, it is essential.
