The Poynting HELI-21 forms part of a series of Mini-HELI antennas. These antennas are only mini in size relative to their bigger brothers, the HELI-3, HELI-4 & HELI-8, but offer medium to high gain, which makes these antennas ideal for mining tunnels where IoT/M2M connectivity is deployed and can also be used for coverage into the stopes. The HELI-21 is a dual-band 2.4 GHz and 5 GHz Wi-Fi antenna, radiating in one direction (i.e., uni-directional). This makes them ideal for the coverage of both Wi-Fi bands in mining and other type of tunnels. These antennas are typically used for the deployment of IoT within the tunnel to provide telemetry and mine automation. These antennas are available in both Left-hand Circular (LHC) & Right-Hand Circular (RHC) polarised antenna elements to provide optimal decorrelation within a MIMO deployment when using the BRKT-45, resulting in optimum performance. The decorrelation is due to the polarisation difference and spatial diversity, between the two antenna elements, which enhances MIMO performance and RF reliability within a mining tunnel. The dual-band Wi-Fi connection propagates around tunnel bends in a Non-Line of Sight scenario and provides immunity to many Wi-Fi signal disrupting objects such as trains and drilling machinery which appear to obscure the tunnel.

Product Features:

• The antenna features four ports operating on both the 2.4 GHz and 5 GHz Wi-Fi bands.
• It is engineered for mining operations and tunnel environments where rapid network extension is required.
• The uni-directional design radiates signals in a single direction along the tunnel axis.
• Left-hand and right-hand circular polarization options are available to support MIMO configurations.

Application Areas:

• It supplements fibre or leaky feeder cable hotspots to extend network coverage into inaccessible underground areas.
• The antenna supports underground telemetry and automation systems.
• It enables the creation of comprehensive tunnel-wide data networks, providing internet and LTE connectivity throughout the tunnel.
• It ensures seamless connectivity for personnel using cellular phones, smart devices, and tablets in subterranean environments.
