NOTE: A site inspection conducted by a MST System Engineer will help determine
the power requirements for your network.
AXON Core is designed to operate at a wide voltage range, from a minimum of 20VDC up to 60VDC.
Each AXON Core in a network can internally step up the incoming voltage to 48VDC in order to
supply power to its connected PoE devices. AXON Core needs to receive a minimum input of 20VDC
to power PoE devices.
56VDC power supplies are used for large networks to maximise the distance between power
supplies. For instances where the AXON Core switches are deployed in isolation or in remote
location a 24V DC UPS can be used.
External power supply recommendations:
Using Uninterrupted Power Supplies is not mandatory; however, it will increase the uptime and
protect the network from power surges and fluctuations. Fluctuations may cause damage to the
network and auxiliary equipment. The recommended UPS is AXON Force UPS.

Choosing Antennas
Antennas are connected via N-Type connectors to each AXON Air to provide wireless network
coverage. The type of wireless coverage, surrounding geology, tunnel topology and surface of the
roadway/tunnel are all factors that will determine the choice of antenna. A minimum of two antennas
is required for each AXON Air. There two most popular directional antenna patterns:
Omnidirectional antennas — radiate equally in all directions for a short range, providing
immediate coverage in an open area.
Directional antennas — radiate in a specific direction over a longer range. A higher gain antenna
will have a longer range and is more directional. It is important that directional antennas are
aligned properly between AXON Air units to ensure continuous coverage between units.
The antenna radiation pattern and polarisation need to be considered to provide suitable wireless
coverage in an area.
Antennas commonly used with AXON Air are shown below.
ntenna Type Illustration Description
Omnidirectional 2.5dbi
rubber whips
lower gain antenna that radiates equally in
all directions. It provides direct coverage in an
open area.
Panel antenna
panel antenna is a directional antenna, with
a wide horizontal beamwidth and narrower
ertical beamwidth. They are suited for
covering an open area in one direction.
