Ausgrid is investing more than $1 billion in the Sydney CBD electricity network over five years to 2014. Ausgrid's Sydney CityGrid project involves constructing new substations, replacing and upgrading high-voltage cables and constructing a new tunnel to link into our existing network of CBD cable tunnels. These tunnels connect to form an 8 km ring under Sydney's CBD that interconnects Ausgrid's substations.
To provide a GRN P-25 coverage solution into these tunnels for Ausgrid's maintenance staff presented a challenge. Coverage is provided by utilising 'radio over fibre' repeater technology which rebroadcasts the NSW Government Radio Network from two dedicated base station sites located in two of Ausgrid's substations. Radiating cable, fixed to the ceiling of the tunnel, distributes the radio signals to the user in the tunnel, providing a method of communications deep underneath Sydney's CBD, where previously there was no way of communicating with the outside world.

Overcoming high deployment costs of synchronizing Enterprise Small CellsDavid Chambers
LTE-Advanced features require tight frequency and phase timing to synchronise with other nearby cells and are far more demanding than 3G or even the initial LTE services. This is particularly difficult to achieve indoors where satellite GNSS signals are weak.
Often the deployment costs far exceed those of the equipment where external GPS antenna are used, such as negotiating rental of suitable roof space, cabling for external GPS antennas, installation and ongoing maintenance. Reliance on a single technology also raises availability concerns in case of outage.
This webinar reviews the importance of phase timing and how best that can be achieved for indoor small cells. Microsemi will also introduce an innovative solution that drastically reduces installation and deployment costs while achieving the high precision of frequency and phase synchronisation required.

Improvement of signal coverage using wcdma signal repeater for 3 g systemsIjrdt Journal
Wireless communication has become an indispensable technology for the society. In broadband wireless data transmission technique, 3G cellular systems are expected to provide high data rate and less probability of error. This repeater finds application in areas of poor signal coverage and connectivity. The repeater consists of a patch panel antenna for receiving WCDMA signals from the base station and amplifying the signals using a wideband RF amplifier. The signals are then retransmitted to the weak coverage area using a directional Yagi-Uda antenna. The antenna characteristics such as return loss and VSWR are measured using a Network analyzer. The component of the repeater are mounted in a stand and the performance of the entire unit was evaluated using a WCDMA generator, act as a base station, transmitting at 869 MHz and 5dBm output power. A spectrum analyzer with WCDMA analyzer is used as a receiver, the RF signal level and constellation plots with error vector magnitude are determined

Integrated communication networks for coal seam gasComms Connect
The coal seam gas industry has recently become one of the fastest growing industries in Australia with a majority presence in Queensland. To illustrate this, in 1999 there were approximately 150 wellheads and today there are roughly 3000. Further to this, industry estimates predict a total of 40,000 wellheads will be required to mine all the proven and profitable coal seam gas reserves.
As coal seam gas drilling grows in size, so do the communication and control systems. Due to the fast pace of expansion, legacy systems and regulations, companies can find it difficult to keep up with the unique demands of a coal seam gas communications network. This presentation investigates typical CSG communication systems, ideal future architectures and the challenges companies face in getting there.

The value of communication networks in a public safety environmentComms Connect
The communications environment for Public Safety Agencies today and into the future, is increasingly fluid and shaped by a dynamic mix of continuing and emerging challenges, technologies, expectations and opportunities. This delivers a need for immediate access to multiple types and channels of communication. Wireless communications are particularly important to support the mobility necessary for field operations, however there is also an emerging need for real time data from incident locations and command centres and airborne solutions.
For the community, the resilience of people and households is significantly increased by ensuring there is an awareness of the threats, thus empowering those affected with information to assist the decision-making processes is vital. This brings into the mix commercial radio, TV and social media. Social media works in two ways, social media channels can provide a source of information from which disaster managers can obtain real-time awareness of developing situations as well as a mechanism for which to communicate outwards. Underpinning the delivery of these essential communication exchanges is the requirement for resilient networks, be that private, public or shared.
Bringing this together, to deliver effective and balanced communication in crisis environments, is just one component of emergency response.

The other radio technologies - why GSM/3G can be complementary and profitable when used with PMR systems.
M2M covers a huge variety of applications and technologies. GSM-based M2M gets a lot of publicity these days as it is seen as the ubiquitous solution for large rollouts, but other radio technologies are often used in critical applications.
There are multiple instances where GSM and PMR are bedfellows and largely it is only the PMR industry that has the sophistication and technical expertise to drive these applications. GSM carriers and app developers struggle to think outside of their own niche, whereas LMR system providers have always had to do a large chunk of their own engineering and development, often taking on the true partner role with their customers, developing on and with them in tandem.
When used in applications that have some or all of these criteria, it is as many times essential as nice to have multiple technologies driving your comms:
- where one mode does not provide the coverage that you need
- where critical public or personal safety issues are involved
- where multiple backup overlays are required because the data is very important and timely
Applications designed for areas like:
- mining - where GSM coverage is patchy at best and PMR is much more effective in a pit
- environment - where delays and breakdowns can cost tens of thousands of dollars or more per hour, where remote-controlled machinery is becoming more common
- personal safety - like lone worker devices
- building and home security - where multiple network paths are now required to achieve the best security ratings and therefore the lowest insurance premiums
- are ideally suited to dual- and multimode technologies
The side benefit of these is that GSM/satellite as an add-on can provide an additional income stream to PMR suppliers as the network providers will pay ongoing revenue shares.

The future of private microwave radio networks in the era of national broadba...Comms Connect
The transition of private networks to IP standards opens up a plethora of backhaul options. These range from simply replacing traditional TDM-based backhaul with IP-based transmission systems of similar capacity to placing the backhaul in the hands of commercial telecommunications carriers and their low-cost IP service options. The promises of ubiquitous broadband coverage from national broadband networks (NBNs) potentially add even more confusion to this already complex design environment.
This paper is based on the recent experiences of ATI in the Australian environment of providing high-capacity broadband backhaul in remote regional areas as well as urban areas. It touches on the important network variables as well as backhaul transmission characteristics in order to provide a set of selection and design guidelines applicable to most network cases, with particular focus on network security and cost.

Is there still room for linking narrowband PMR sites in this digital world?Comms Connect
Historically, professional two-way radio has dealt with the problem of congested spectrum/channels by narrowing the channel spacing, i.e. 50 kHz -> 25 kHz -> 12.5 kHz -> 6.25 kHz, but with new technologies emerging and vast advancements in spectral efficiency Paul Daigneault asks if this is really necessary and, more importantly, is there still room for linking narrowband PMR sites in the digital world?

RF in the IT domain - it's not just wirelessComms Connect
This presentation will address the other options between the usual 'wireless' equipment and the more significant RF capabilities of radio communications. With an outline of IP-connectivity available from radio equipment, through the various digital radio technologies and including the 'apps' that are now available for digital radio systems, the presentation will cover the range of options available. Outlines will be given on the historical limitations of radio equipment and the dramatic changes that are now available as part of the digital technologies, showing how RF now becomes one of the 'platforms of technologies' that are available to IT system designers and managers. The presentation will also address who to approach and how to handle the 'black arts' involved with radio communications; and how experienced professionals can work very accurately within the 'laws of physics' for system design and diagnosis.
The presentation is highly recommended for IT managers, system designers and those generally interested in keeping abreast of all of the options available within the IT domain.
Martin McLeod, Vice President, ARCIA
This session will provide a quick review of the methodology of early dispatch systems connected to radio, telephone and other resources via circuit switched interfaces such as 4WE&M, 2W analogue etc., and their restricted backhaul capabilities, leading on to the 'stand-alone' RoIP boxes that allowed 4W E&M to be converted to IP and recovered at the other end allowing backhaul via more flexible IP networks.
The next technology is dispatch systems with native IP connectivity allowing the most flexible and functional interfaces between the dispatch system and its connected resources. While some manufacturers equipment uses proprietary IP messaging, most prefer and use open standards such as P25 CSSI (console sub system interface), DFSI (digital fixed system interface) and ISSI (inter sub system interface) or the emerging DMR AIS which ensures that different vendors equipment can interoperate with each other via these interfaces. Open standards provide end users with greatly improved competitive choice and functional capability on these systems.
The session will explore examples of IP interfaces for voice dispatch systems and the functions supported, plus give a background on how these apply to many different technologies and can even be adapted for conventional radio applications:
The workshop will cover on the following issues:
- The difference between RoIP and VoIP - how radio systems differ from phone systems

Ensure network migration success with Change ManagementComms Connect
"Change Management" is a term given to the process of taking a structured, methodology-based approach to planning for the people aspects of a new technology implementation. If you're planning to migrate to a digital network, early consideration must be given to the experience of users during this transition.
70% of all major change efforts fail because organisations do not take a holistic approach to change. Part of the focus of any new solution needs to be about the people who will be affected by the change. Change occurs one person at a time, and at different rates depending on how that individual is "hard wired" to adopt to change. Applying a structured and deliberate approach to manage the transformation of your organisation during a network migration, will help to ensure your new solution is embraced, adopted and used proficiently.
This workshop will focus on three critical aspects to ensuring change success:
- Understanding the impact of change on your organisation and people
- Change is both technical and personal.
- Knowing how active and visible "change sponsorship" from the leaders in your organisation contribute to change success
- Senior leaders need to provide authority and credibility on a project's importance and the organisation's commitment to any change.
- Learning how to identify the ROI of change management activities in your organisation
- Three 'human' factors - adoption, utilisation and proficiency - each impact the amount of expected improvement from a solution.
- This workshop will encourage participants to apply change management theory to activities such as network migration or technology upgrades, with a better understanding of the tasks involved in achieving a successful outcome and maximising their investment.

Alternatives to LTE for first responders - the evolution of radio communicationsComms Connect
This presentation will focus on CSIRO's work in radiofrequency communications. Specifically we have a number of patents covered under the brand 'NGARA' and have licensed some of these for use in public safety broadband wireless networks. Ngara backhaul and 'access' (point to multipoint) continues to set records for super high speed, super high efficiency wireless up to 10 Gbit/s. It has won numerous awards, including the Engineers Australia national Excellence in Innovation Award in 2013.
NGARA currently enables up to 18 separate beams each of 50 Mbit/s symmetrical in 28 MHz of spectrum. Leveraging dynamic beam forming, we can get highly targeted narrow beams very close together with powerful auto-alignment of antennas to minimise operational cost and set-up time. These features lend themselves to being able to address some of the challenges faced by public safety network providers. Existing LTE Mobile networks congest very quickly under severe localised traffic generated during emergency situations, and separate highly efficient and targeted network performance is needed during these times of very high and unpredictable demand.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.

RF Design Parameter Considerations
• Link Budget: Downlink Power per carrier (control Channel) for
shared PA.
• The system is designed for a target received signal strength
(RSSI) of -95dBm (control channel) worst case for a single
system, to meet Delivered Audio Quality DAQ3.4
• Frequency Planning for duplexer bandwidth, and avoiding co-
channel and adjacent channel interference between System A
and B
• TDI – Time domain interference due to overlapping coverage
by simulcast signals. Maximum allowable delay is15
microseconds for P25 Phase 2 for signals of equal signal
strength. The difference in fibre lengths to neighbouring
remotes must be within 3000m before TDI occurs. Velocity

• Passive components such as couplers and splitters are used to distribute RF signals to
the leaky feeder and discrete antennas in sub stations.
• 50ohm terminations are used to isolate remotes connected by the same leaky feeder
cable.
