PREPARING FOR THE FUTURE OF DIGITAL TRUNKING

THE DIGITAL DIFFERENCE

Two-way radio has been a successful analog communication solution for generations, and it proves itself every day in countless

deployments around the world. But digital technology breaks through to a new level of performance and productivity for your business.

PREPARE FOR THE ADVANTAGES OF DIGITAL TRUNKING

Digital two-way radios offer several advantages over analog solutions. To name a few:

• Clearer audio to help assure messages are understood without background noise and static

• Integrated data applications such as text messaging, GPS-based location tracking, work order ticket management and much more

• Longer battery life for extended work shifts

• Increased capacity – twice the number of users for the price of one frequency license

TDMA – THE BEST CHOICE

There are two primary digital radio technologies: Time-Division Multiple-Access (TDMA) and Frequency-Division Multiple-Access

(FDMA). While both digital technologies provide signiﬁcant beneﬁts over analog, TDMA is the best choice.

TDMA technology delivers advantages over FDMA

• Double your capacity per channel with less than half the infrastructure

TDMA divides your existing channels into two time slots enabling you to double the number of users on your system or utilize data

applications without the expense of additional infrastructure. A second call does not require a second repeater, resulting in lower

costs for you, as you do not need to purchase, install and maintain additional infrastructure equipment.

• Double your capacity per channel without the hassle

Speciﬁcally, TDMA divides your existing channels into two time slots so your existing licensed channel capacity is doubled. There

is no increased risk of interference, and there is no need for new licenses—simply amend your existing licenses to specify digital.

Compatibility with all legacy radios working in 12.5 kHz analog channels is also maintained by TDMA.

• Longer battery life

TDMA uses only half of the transmitter’s capacity resulting in longer battery life. During long work shifts or where productivity

enhancing data applications place an increased power demand on the radio, this extended battery life is invaluable.

• Advanced features

TDMA enables smart control features like “transmit interrupt” that makes it possible to interrupt lower priority communication

so critical instructions can be delivered exactly when they’re needed. And to help you maximize your infrastructure investment,

TDMA can transmit voice and data on the same channel.
