Digital two-way radio technology was created to address the
problem of overcrowded frequencies – referred to as achieving
spectrum efficiency. With millions of analog radios in use,
too many users in a frequency band impacts the quality and
reliability of communications, putting safety and productivity
at risk. In certain countries, there are regulatory requirements
being implemented that mandate manufacturers to only
produce and sell digital two-way radios.
As a result, most radio manufacturers are primarily investing
in developing new digital radio technology options to meet the
growing needs for more efficient two-way radio communications.
Digital transforms the way people communicate and use two-
way radios on the job.
While analog radios have been used for years – there are
limitations to their performance that many users have been
conditioned to just accept:
• Audio Quality -
Background noise and static
• Inconsistent Performance -
Irregular experience in
transmitting and receiving calls
• Usable Range -
Coverage gaps in how far radios will
• Lack Of Privacy -
No control over who can hear calls
placed over the radio
• Channel Congestion -
Distracting radio noise risking
missed important calls
• Call Management -
No easy ability to place direct calls
to select individuals or groups
• Multiple Site Connectivity
- Can only be done in Digital
DIGITAL MAKES TWO-WAY RADIO
Users can achieve improved and expanded communications
capabilities with the advancements of digital technology that
overcome traditional analog performance challenges combined
with a new set of features enabling users to do more – better.
BETTER CALL QUALITY
- Digital applies error correction to eliminate noise and
static and preserves voice quality over a greater range so
users can hear what is being said crisp and clear. Use of the
AMBE+2™ vocoder further improves speech transmission
quality in noisy environments while achieving spectrum
- Digital enables users to make more calls to more
places. A digital signal stays strong and clear until it reaches
its maximum range. There is no deterioration in the signal,
providing greater usable range in areas where two-way
communication was not possible in the past.
BETTER CALL MANAGEMENT
- A common desire amongst analog radio users is
to control who receives a message and avoid broadcasting
messages to a wide group of listeners. Digital makes this
possible with unique IDs assigned to each radio. A user can
selectively call specific individuals or groups by selecting the
radio ID(s) to direct a message only to those who need the
CALL MANAGEMENT CAPABILITIES
• Individual Call
- One user directly calls another user and
cannot be heard by anyone else on the channel.
• Group Call
- One user can call a select group of users. All
parties in the group hear each other and cannot be heard
by anyone outside the designated group who may be on the
• All Call
- One-way voice transmit from one user to all users on
• Late Entry
- While an individual or group call is in progress,
latecomers are joined into the call.
- Digital enables sending/receiving free-form or
preset text messages. Users have more ways to stay connected
when voice communication is not feasible or messages need to
be stored for reference.
- No extra encryption hardware is required to ensure
private communications when operating in digital mode.
Only the intended recipient(s) hear what is transmitted without
the risk of significant loss in voice quality that can be
experienced with analog scrambling.
