Backhaul — January 2019

25 YEARS AGO. The cover of the Feb/Mar 1994 issue of What’s New in Radio Communications featured the GME Electrophone TX5200 series of trunked mobile radios, designed to fully comply with MPT1327/1343 specifications but with the ability to use conventional PMR mode with CTCSS for trunking bypass. Inside the magazine we reported on Omnitronics appointing Neil Muller as the exclusive distributor of 9000/9200-series telemetry equipment in South Australia. Omnitronics also featured in the world speed record attempt by Rosco McGlashan in Aussie Invader II, vital telemetry for which was sent over the air using the company’s microprocessor and I/O cards. Telstra Maritime Services was reported as releasing an advanced new direct-dial microphone to enhance its growing national Seaphone network. David Cooke (RFS Australia) and Richard Chocolate (Celwave, USA) showed us the long and short (and thin and fat) of choosing antenna subsystems. WA-based Transom International was awarded a $5.7 million contract to install its comms technology in Malaysia’s largest long-distance bus fleet, and Auspace had received orders for its GPS Multinav module from customers in India, Thailand, China, Taiwan and Indonesia.

10 YEARS AGO. The cover of the Jan/Feb 2009 issue of Radio Comms Asia–Pacific featured the Rohde & Schwarz FSH4 and FSH8, lightweight, battery-powered spectrum analysers (9 kHz to 3.6 or 8 GHz). We reported on C4i winning a $9 million contract to supply its Alarmon system to 20 major and regional airports across Australia, and Benbro Electronics bought 23 GME AccuSat personal locator beacons for use by bushwalkers in the Blue Mountains on a free-loan basis. We also reported on research by a Spanish industrial consortium, led by Teltronic, into combining TETRA’s narrowband services with an extension via broadband wireless base stations and mobile devices into a single Ethernet/IP architecture. And our feature article showed how Australia’s largest timber plantation company, Melbourne-based HVP, worked with ComGroup to install Simoco radio and GPS equipment to improve worker safety.
