PO-HELI-4is

 

Overview

Poynting has fifteen years’ experience in designing and manufacturing antennas for underground mining data networks.  The HELI-3is is an Intrinsically Safe antenna with high resistivity non static radome.  This antenna is also suitable for oil/gas chemical environments
where IS equipment is required. The tunnel antenna is the ideal antenna for 2.4-2.5 GHz wireless applications in tunnels. In tests, both
the data rate and range achieved with this antenna was greater than obtained when using linearly polarized panel antennas of
the same gain. The hardy construction of this antenna makes it ideal for the mining environment. This antenna gives you a low cost
network infrastructure for current voice and data needs in mines and tunnels.

Application Areas:

• Supplementing fibre/cable networks by providing wireless “Hotspots” to areas to enhance mobility or extend networks to inaccessible areas such as mines and tunnels
• Underground telemetry
• Creation of complete in tunnel/mine wide data networks and or internet connectivity
• Seamless connection to personnel using VOIP phones, smart devices and tablets
• M2M applications
• Extension/deployment of wireless connectivity on oil rigs, refinery, factories where intrinsically safe equipment is required.
