City Parklands Services Pty Ltd manages operational services for two Brisbane parklands. To improve communications for staff, a Motorola Capacity Plus system was implemented with 90 radios and two repeaters. This provided complete radio coverage, including in underground areas where coverage was previously inadequate. The system improved worker safety by ensuring emergency calls are received, increased productivity through better communication between teams, and ensured adequate communication channels for all staff groups.
Incremental wireless developments have seen a string of progressively more complex analogue modulation schemes, but no digital systems. Our old analogue technologies are merely interfaced with complex digital modems and we have failed to escape the constraints of bands and channels. But our world has moved on from big towers, high energy, and long distance communication to one dominated by very short range, mW, µW and nW transmissions. Even the mobile device world is migrating to smaller and smaller cells, whilst the IoT may predominately by-pass all our conventional networks by employing mesh nets and/or opportunistic store and forward.
“A world of 250Bn fixed and mobile ‘Things‘ is entirely different to one of 7Bn Mobiles”
In this new paradigm the apparent shortages of wireless bandwidth and capacity are more a manifestation of wrong thinking than actual constraints of a well trodden analogue past. The reality is; we have an infinity of bandwidth and there are no physical or otherwise limitations to wireless communications for short distance applications provided we think and design digitally to exploit all the degrees of freedom to hand. In the extreme, we can operate under the thermal noise to become invisible and beyond regulation and control.

Enhance Communication And Coordination On The Road With Vehicle Two Way RadiosCraigStewart89
Vehicle two way radios are a quick and efficient way for teams and drivers to stay in contact while traveling. They cannot be compared to conventional cell phones because they use radio waves instead of dialing numbers and waiting for a connection. As a result, they benefit sectors and users where prompt and direct communication is crucial.
How Is The Two Way Radio Callbox Technology Game Changing.pdfCraigStewart89
Digital technology has significantly revolutionized the communication domain, resulting in the invention of instant and versatile internet communication tools like the Two Way Radio Callbox system. This technology combines the dependability of everyday radio communication with the modern digital network's capability for real-time two-way conversations, providing a powerful tool for interaction in diversified situations.

A roadmap to deliver next generation critical communicationsComms Connect
Mobile communications, especially in emergency situations, but also as businesses increasingly use mobile connectivity for their operations, is becoming critical. Public safety, emergency response, crisis control and smooth day-to-day operations all rely on people connecting and information being shared accurately. Telstra today is enabling voice and narrowband communications through both private and public mobile networks, while working to develop an integrated mobile broadband solution to meet the needs of tomorrow for emergency services, mining, transport and utilities.
This presentation will explore the coverage, resiliency and customer experience that underpin the Telstra mobile broadband communication network, and the roadmap Telstra has to deliver an emergency- grade mobile network that offers dedicated spectrum coupled with the reach and mobile broadband experience that Telstra offers.

09:15-09:55 - The changing face of communications
Speaker: Paul Wakefield, SIP product manager, Gamma.
We are all facing a communications challenge, be it as a supplier, manager or consumer. Users are demanding more, and as a result the expectation is there to provide more services, with faster deployment and less resource (both money and people!).
As the number one supplier of SIP services in the UK, Paul will take you through his view of this market and the fundamentals needed to thrive in this period of change, along with emerging technologies and trends.
The relationship between Gamma and Jisc is a great example of how innovative solutions can deliver tangible benefits to all. As the largest supplier to the Janet community, and you can also hear about the latest developments and support for clearing in particular.
09:55-10:35 - Best practices for planning your campus network growth
Speakers: Leon Champken and Mark Sunderland, both Ruckus Wireless.
Many colleges and universities are faced with the daunting challenge of upgrading their campus network infrastructure to keep up with or get ahead of rising wireless usage by students. The promise of 802.11ac Wave 2 Wi-Fi and stackable software upgradeable switches and the adaptability of software-defined networks (SDN) has IT departments considering new vendor platforms, architectures and products.
Where do you start, if you do not have the budget, people or time to rip and replace your existing network? Attend this session to learn a checklist of considerations for migrating your campus from your legacy network vendor in a workable, phased approach.
