What
is a wireless intercom?
A wireless intercom must function in the same fashion as a wired
intercom but have the advantage of being wireless and so allow complete
freedom of movement.
It should be exclusive to the user group and highly resistant to
interference, support at least two or more people in full duplex
mode at all times and be constantly open and hands free in operation.
It should also be operational for many hours at a time without a
break.

Who
would use a wireless intercom?
Intercoms
with these characteristics whether wired or wireless are essential
for many work environments where instant and secure communication
with a number of other users are available at any time, regardless
of whether there is a pre-existing transmission taking place. In short,
the ability to conference.
Operatives
in areas of high ambient noise levels or restricted visibility may
need to pass information between each other without delay or loss.
Examples
include:
Machinery or Process operations
Vehicle intercoms
Crane, quayside, forklift or warehouse operations
Hazardous areas where users are encumbered by protective clothing
and equipment
Construction and scaffolding
Firing ranges
Theatres and Broadcasting and studio
Marine operations, ROV Retrieval
The
DECT wireless intercom from Atlantic Instruments improves operational
safety and efficiency in the workplace.
Components
and operation:
A typical four user system will comprise a base station, a handset
for each user and a headset for each user.
Each transceiver automatically registers with the base station.
Individuals must remain within range of the base station in order
to communicate with each other.
The Base station is mains powered but for additional safety has an
internal rechargeable battery which will last for four hours in the
event of power failure. Another feature is that this makes the system
portable in the field for up to four hours with no supply at all.
A 12 Volt supply can be provided if required for indefinite operation.
The Handsets are rechargeable and will last up to 20 hours, enough
for a full shift.
Specification.
The System is based upon the DECT (Digital European Cordless Telephony
) standard.
The frequency used is 1.88 GHz to 1.90 GHz.
Peak output power is 250mW, the average power is 10mW.
The maximum Line of Sight (LOS) range is 200 meters with 50 meters
through structures.
The system is Licence Free in all European countries and a total of
112 countries around the world
A maximum of eight users can be accommodated on any one base station.
The base station has the ability to connect to an external communication
source such as a telephone, external radio system or another headset
or microphone.
The system is confidential and once it is running it cannot be interrupted
by another DECT system.
The Coverage can be increased by using additional base stations
Flexibility
This system is adaptable to almost any situation and works extremely
well.
Other types of headsets and microphone arrangements are available.
You may feel that this system would be ideal for your application
but you have an additional issue due to the nature of your workplace
or the job in hand.
I have the experience to deal with any additional requirements you
may have.
Accessories for the wireless
intercom
Not all users find a headset to be the ideal
interface to the intercom system.
Shown here is the desk console unit which is
plugged into the handset or basestation to provide a full duplex link
to operators outside for instance a control room or office.
