obstructions.

Important:

Check that all

unused antenna ports remain
covered with the supplied
antenna port covers.

2.4 Antennas

An NS40 has two antenna ports for each 802.11b/g wireless radio. Antennas are connected to the NS40
to optimise wireless signal coverage in the underground mining environment.

The choice of antenna will depend on wireless coverage, surrounding geology, tunnel topology and stratum
type. The antenna types used in a network are described below.

Antenna Type

An antenna that radiates equally in all directions. It
provides direct coverage in an open area.

Omndirectional
antenna

A diversity panel antenna contains two antennas. It is used
for providing better signal reception in difficult areas, and

Diversity panel
antenna

a more accurate AeroScout tag location when Wi-Fi
tracking is implemented. Diversity antennas require two
antenna connections to the network switch.

A Yagi antenna is a highly directional antenna providing
a very narrow but longer horizontal beamwidth. They are

Yagi directional
antenna

ideally suited for line of sight tunnel communications. Yagi
antennas need to be aimed accurately and avoid obstacles
in their RF beam path.

Note:

Only approved antenna models can be connected to the NS40. Please consult your MST

System Engineer for any queries.

2.4.1 Antenna Placement and Layout

Antennas are usually mounted separately from an NS40 to optimise transmission and avoid any obstructions
in a mine tunnel. An antenna splitter can be used connect two antennas to a single antenna port. This
provides greater flexibility in the configuration and placement of antennas to improve wireless coverage.

Antenna placement is dependent on the surrounding geology, tunnel topology and stratum type. Antennas
can be configured in different layouts to achieve different RF patterns.

The following considerations in the placement of antennas are described and illustrated below.
