Prototyping next-gen wireless systems with software-defined radios

Supplied by National Instruments Australia Pty Ltd on 18 April, 2017

Software-defined radios (SDRs) have emerged as a viable prototyping option for next-generation wireless research by enabling researchers to quickly prototype a system, characterise its performance and iterate the design.


5 key trends driving digital mobile radio innovation

Supplied by Motorola Solutions Aust Pty Ltd on 08 March, 2016

Customer demand is the catalyst for most innovations in today's DMR technology. Businesses now need to adapt to customer trends and do more with less to succeed in this rapidly changing environment.


Prepare your backhaul networks for LTE and beyond

Supplied by Alcatel Lucent on 02 December, 2015

Public safety communications are changing with the adoption of broadband-based multimedia applications, IP-based radio and LTE. In preparation, TDM-based backhaul networks are being replaced by converged WANs. This transformation should include an IP/MPLS — the only work network that can provide the capability and reliability that is mandated by mission-critical services.


Digital radio transmitter alignment: critical for optimal performance

Supplied by Vicom Australia Pty Ltd on 24 November, 2015

Transmitter alignment greatly affects the performance and coverage of digital radio receivers. Improper alignment commonly leads to performance losses of up to 75%. Your radio network coverage can easily be improved with the proper understanding of this digital radio technology.

Understanding VoIP: network characteristics, protocols and test tools

Supplied by Zetron Australasia on 16 December, 2013

This white paper discusses the basics of VoIP technology - the transferring of voice signals over internet protocol (IP) networks - as well as the benefits and pitfalls of using it.


Deploying reliable fibre-to-the-antenna networks

14 June, 2013

Mobile network bandwidth demands continue to increase with no end in sight. The subscriber hunger for higher bandwidth and higher capacity services is driving fibre deeper and higher into the radio access network (RAN). This paper explores the challenges of deploying reliable and robust fibre-to-the-antenna (FTTA) networks in addition to reviewing industry standards.


Helping you hear: hearing protection and communication devices eBook

07 December, 2012

Headphones and headsets have not only been used for listening to music over the years, they have played an integral part in safety and communications and are currently used in a wide range of industries. The technology has grown with the times and devices have been redesigned to include features such as noise cancellation and acoustic shock protection to meet strict safety standards and workplace regulations.


Understanding cable and antenna analysis

31 August, 2010

The cable and antenna system plays a crucial role of the overall performance of a base sta¬tion system. This white paper covers the funda¬mentals of the key measurements of cable and antenna analysis: return loss, cable loss, and distance-to-fault (DTF).
