CURRENT MARKET STATE

Radio Resource Magazine Survey*

• 70% of readers still use Analogue Conventional networks

• Around 60% of survey responders using digital.

• Over 70% of Analogue Conventional users plan to

migrate to digital in 5 years or less.

- 53% within 2 years

- 19% within 5 years

• Around 10% have no plan to go to digital

CURRENT MARKET STATE

IMS Research report “Licensed Mobile Radio – World

2012 *

• IMS estimate 80% of market still Analogue in 2011

• Estimate total market in 2012 to be 7 Million subscribers,

and growing to 8 Million by 2016.

• “The transition to digital is here to stay” – Thomas Lynch - IMS

DIGITAL ADVANTAGE

Spectrum Efficiency

• More efficient VOCODER means less data to be

transmitted.

• Less data to transmit means less spectrum required.

AUSTRALASIAN SAFARI

REQUIREMENTS

• Rugged radios

• Digital clear audio

• GPS location for rescues

“ It’s fantastic to be able to sit back and

watch on the mapping screen, knowing

everyone is OK. The network and radio

system has taken out a lot of the risks – it

has really revolutionised this event.”

Justin Hunt, director, Australasian Safari
