Poynting have an established history of providing circular
polarised antennas for mine tunnels internationally. The MinePoynt (HELI) range
of antennas are well established for several years and deployed in many mines
and tunnels in Europe, Australia, Africa, USA, Canada and other countries
internationally. With the high demand in underground antennas, and for new
technologies such as WiFi-6 and LTE/5G, Poynting have developed a new range of
antennas that offer both dual-band 2.4/5GHz and LTE/5G mine tunnel antennas in
a smaller size enclosure.
High bandwidth communication systems perform a vital role in
the safety and productivity in tunnelling operations, enabling modern
underground operations to use communication systems that enable secure voice
communications, to locate both people and machines, remote control of vehicles
and systems, and site access and security.
In recent years the proliferation on M2M and IoT
applications above ground has moved underground and highlighted the requirement
for better quality communication in mines and tunnels that can seamlessly move
to networks above the ground.
The new mini-HELI range of mine tunnel antennas are only
mini in size relative to their bigger brothers, the already popular HELI-3,
HELI-4 & HELI-8 and offer medium to high gain while providing the smallest
possible installation height for mounting on the tunnel roof or side wall. This
new range of antennas is typically used for the deployment of IoT within the
tunnel to provide telemetry and mine automation and can also be used for
coverage into the stopes and smaller tunnels. The Mini-HELI range of antennas
offer different variants (model numbers) for dual 2.4GHz/5GHz.
Poynting have expanded their purpose designed mine tunnel
antenna to offer the new Mini-HELI range of slimline circular polarised antennas.
These antennas are designed with a low profile, capable to offer Dual-band
Wi-Fi and LTE/5G/WiFi-6 connectivity within the same series.
Coverage range of these antennas have been tested to exceed
conventionally deployed antennas, with underground measurements of between 400m
and 1km achieved, reducing the cost of deploying too many access points /
radios. Making use of these antennas, with their dual/multi frequencies, MIMO,
bi-directionality and circular polarisation features, enables a more stable
underground communication system with less signal fading and much higher
reliability when compared to normal industrial Wi-Fi and LTE antennas.
The following models are available in the mini-HELI antenna series.
A preconfigured set of antenna assemblies are available for
ease of ordering. These assemblies consist of BRKT-045-V2-01 and two antennas
with both Left Hand Circular (LHC) Polarised and Right- Hand Circular (RHC)
polarised antennas as follows:
