1.2 System Layout

WNS units are installed in a mine to form a wired and wireless network. This section describes a simple WNS system layout in a mine as shown in Figure 2: Typical WNS system layout.
The first WNS in a network is connected to an Ethernet switch and power supply either by composite cable (providing power and network connectivity) to the WNS, or connection to the WNS Ethernet port and external power jack.
WNS units are typically connected in series down the mine tunnel by composite cable. When the mine tunnel splits into different sections, an additional WNS is branched from the network. WNS or Wireless Access Point (WAP) devices can also be positioned in Wi-Fi ‘hot spots’ such as crib areas and refuge bays.
A PC or mobile device can connect to the network when in proximity of an WNS or WAP.
Figure 2:Typical WNS system layout

1.3 Connectivity

The WNS has three types of network connections:

Composite Fibre Ports
Ethernet Ports
Wireless

1.3.1 Composite Fibre Ports

WNS units have up to four composite fibre ports, interconnected by composite cables. The composite cable contains fibre optic data cores and power (as shown in F igur e 3: WNS composite cable connection), and connectors designed for durability in underground mines.
Figure 3:WNS composite cable connection
The composite cable overcomes the challenge of limited power access in mines by distributing power between each WNS in a network. The fibre optic cable contained in the composite cable also provides the following benefits over standard Ethernet cabling:
WNS units can be spaced up to several kilometres apart, compared to Ethernet cabling with a distance limitation of 100 metres. This reduces installation cost, component count and likelihood of faults.
Fibre optic cable has superior signal integrity , with no signal interference from high powered electronics, such as variable speed drives.

1.3.2 Ethernet Ports

The WNS has four optional internal Ethernet ports and four external Ethernet ports enabling connection to client devices or other networking devices.
The four external Ethernet ports also provide IEEE 802.3 af PoE (Power over Ethernet) injector functionality, allowing a single cable to be used for data and power to network devices. Each Ethernet port's functionality can be configured by the web browser interface, or by centralised configuration management. For more information on configuring Ethernet ports, see Configuring the VLAN Port Map on page 65.
Wireless Network Switch User Manual17Revision A
Understanding the Wireless Network Switch

1.3.3 Wireless Access

Wireless connectivity in each WNS is implemented using a WAC (Wireless Access Card), consisting of a wireless network processor and an integrated mini PCI 802.11b/g adapter.
A WNS can contain up to two WACs. The WAC contained in the first radio card slot (on the left side) also acts as the management CPU for the switch processor. As such, it is mandatory that this WAC is fitted to each unit. The WA C operational parameters can be configured through the web browser interf ace or by centralised configuration management. For more information, see Configuring Wireless Radio on page 52 and Editing Site Configuration Files on page 87.

Determining Wi-Fi Distances
between Wireless Network Switches
This chapter describes network system design for underground mines. A MST System Engineer will usually design and preconfigure a
network based on the requirements and layout of each mine site. This will involv e a visual inspection of the mine site to identify user areas, and determine access point locations. A RF (Radio Frequency) site survey is also conducted to understand the behaviour of radio waves in the mine. The following factors help determine network design:
Wireless coverage requirements of the mine
Quantity and type of wireless client devices connected to the network
Wired client devices connected to the network and their location
Interconnection to the mine's existing corporate network
Policies for network protocol between networks
Cabling requirements
Antenna types to use with each unit and mounting method for each antenna
Mounting location and installation method for each network device.
Wireless Network Switch User Manual19Revision A
Network System Design

2.1 Installation Types and Coverage

Wireless network coverage can be described as:
Wi-Fi hotspot — Network coverage is provided in key areas, such as crib areas and refuge bays.
Full coverage — Seamless wireless coverage by strate gically placing WNS units so their radio fields
overlap.
A WNS can communicate at wireless distances of 150-300 meters, depending on the geometry and geology of the mine.

2.2 Power Requirements

The power requirements for a network are unique to each site installation. Determining power requirements can be complex and is dependent on various factors such as the number of WNS units, PoE devices, branches in the network and composite cable lengths.
Note: A site inspection conducted by a MST System Engineer will help determine the power requirements for your network.
The WNS is designed to operate at a wide voltage range, from a minimum of 10VDC up to 50VDC. Each WNS in a network can internally step up the incoming voltage to 48VDC in order to supply power to connected PoE devices. The WNS needs to recei v e a minimum input of 15VDC to po wer connected PoE devices.
48VDC power supplies are used for large networks to maximise the distance between power supplies. For smaller networks of 1-2 nodes, it is recommended that a lower v oltage 24VDC po wer supply is used.

2.3 Choosing Antennas

Antennas are connected to each WNS to provide wireless network co verage. The type of wireless cov erage, surrounding geology, tunnel topology and stratum type are factors that will determine the choice of antenna. A minimum of one antenna is required per WAC in a WNS.
Antennas consist of two directional 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 WNS units.
The antenna radiation pattern and polarisation need to be considered to provide suitable wireless coverage in an area.
Antennas commonly used with the WNS are shown below.

DescriptionIllustrationAntenna Type

5.5dbi rubber whips
Panel antenna
Diversity panel antenna
Yagi directional antenna
A lower gain antenna that radiates equally in all directions. It provides direct coverage in an open area.
A panel antenna is a directional antenna, with a wide horizontal beamwidth and narrower vertical beamwidth. They are suited for cov ering an open area in one direction.
A diversity panel antenna contains two panel antennas in one housing with a 90° rotation between them. It is used for providing better signal reception in difficult areas, and more accurate AeroScout® tag location when Wi-Fi tracking is implemented. Diversity antennas use both antenna connections on a WAC.
A Yagi antenna is high gain directional antenna. They are ideally suited for line of sight tunnel communications. Yagi antennas need to be aimed accurately and avoid obstacles in their RF beam path.

2.4 Placement of Wireless Network Switches

A site inspection will determine the best positioning of cables, WNS units and antennas prior to installation. WNS units with antennas directly attached should be mounted in an elevated position, within line-of-sight of mobile devices. Ideally this would be situated high up on a tunnel ceiling or on the rock wall face. The mounting location should be free from debris, and avoid obstruction to vehicles, equipment/machinery, vent tubing and cables.
WNS units should not be installed in cut-out areas such as safety bays and remuck bays, due to signal confinement. In such instances, a WAP is more suitable, connected to the nearest WNS. For details on common WNS mounting scenarios, see WNS Mounting Options on page 26.

2.5 Placement of Antennas

Antennas are usually mounted separately from each WNS to optimise transmission and avoid any obstructions in a tunnel. They are connected by coaxial cable. The coaxial connection should be kept as short as possible to minimise signal attenuation. Larger antennas / longer cable feeds can require line amplifiers, and possibly bi-directional splitter / combiners for dual antenna systems.
Antenna placement is dependent on the surrounding geology, tunnel topology and stratum type. The recommended placement of antennas is as follows:
Wireless Network Switch User Manual21Revision A
Network System Design
Tip 1: Directionality
Antennas should be mounted and angled to give optimum transmission along curves and dips as shown below in Figure 4: Angling antennas.
Figure 4: Angling antennas
Tip 2: Obstructions
Antennas should be mounted to avoid signal obstruction from rock, vehicles, equipment and machinery as shown in Figure 5: Antenna mounting to avoid obstructions.
Figure 5: Antenna mounting to avoid obstructions
Tip 3: RF Field Overlap
Multiple antennas should be mounted to avoid crossing signal paths as shown in Figure 6: Antenna
directivity.
Figure 6: Antenna directivity
Revision A22Wireless Network Switch User Manual
Network System Design
The positioning of the antennas is crucial when AeroScout® tags are used for asset tracking and location services. AeroScout® tags will not be read when there are antenna standing wave nulls. Antennas need to be positioned to have best reception of tag messages.
For Antenna mounting options, see Antenna Mounting Options on page 27.

2.6 Determining Wi-Fi Distances between Wireless Network Switches

2.6.1 Line of Sight Distances

In line of sight, a WNS has a maximum wireless range of 300 metres (984 feet) using high gain directional antennas. WNS units are generally installed with a 100 metre (328 feet) overlap of the radio field as sho wn in Figur e 7: Wireless channel layout and distances. This ensures sufficient cov erage between WNS units.
WNS units within range of each other must be configured with different W i-Fi channels. By default e very fifth channel is used (channels 1, 6 and 11) to prevent signal overlap, minimising the possibility of inter-modulation or interference.
Figure 7:Wireless channel layout and distances

2.6.2 Distances Around Curves

The wireless range of a WNS decreases when going around curves. In this case, WNS units need to be installed closer together to provide sufficient coverage. Distances between WNS units will vary depending on the drift and tightness of the curve. They are installed closer together on a tight curve.
Use the following steps to estimate the distance between WNS units:
1. Install one WNS unit at the beginning of the curve.
2. Install the second WNS unit between 20 metres (65 feet) to 40 metres (130 feet) from the end of the
curve.
3. Perform a RF signal strength test by walking from the first WNS to the second WNS.
4. If the strength test records levels of:
Wireless Network Switch User Manual23Revision A
Network System Design
-80 to -65, the WNS units are spaced for optimal coverage.
-81 to -100, move the second WNS closer (at 10m interv als), and conduct another RF signal strength test.
-64 to -10, move the second WNS further away, and conduct another RF signal strength test.

This chapter describes WNS and antenna mounting options, installation schemes, antenna and cable connections. Fibre connector assembly and cable termination in the WNS are beyond the scope of this manual.
Important: The electronic components in a WNS are designed to be isolated from the enclosure and local electrical earth. This ensures there is no current passing between grounds of different potentials (known as galvanic isolation). Galv anic isolation must always be maintained, with the WNS ground terminals isolated from electrical earth, and all antenna and antenna cable connections properly insulated.

3.4 Connecting Power to the Wireless Network Switch

A pre-deployment power-up test of WNS units is recommended. To conduct a power-up test:
Wireless Network Switch User Manual33Revision A
Installation
1. Connect the composite fibre/power cable to a DC power source with correct termination. Note that the
DC supply must be between 10 and 50VDC.
2. Turn on the DC power supply and verify that the green power light is lit.
Power can be applied to cabling whilst additional WNS units are being installed. Power usage levels should be evaluated prior to adding more units downstream to ensure that the voltage rail does not drop too low. A minimum of 15VDC is required for a WNS to supply PoE to other devices. If the voltage drops below 15V, a power inserter is required.

3.4.1 Installing Additional Power

Power inserters may be necessary to provide additional po wer in a large network or when there are branch WNS units. This additional power can be inserted via the DC jack on the WNS as shown in Figure 13:
Power inserter DC jack.
Figure 13: Power inserter DC jack

3.5 Handling Composite Cable During Installation

The composite cable is ruggedly built for the mining environment. However the following precautionary measures should be noted during installation:
Never pull or create tension on the cable. Unreel the cable from the cable reel, or allow the weight of the cable to unreel as the vehicle is moving as shown in Figure 14: Handling composite cable.
Do not be bend the cable at sharp angles; excessive bending can fracture or break the fibre optic cable.
Do not step on the cable.

3.6 Connecting Composite Cable to the Wireless Network Switch

A composite cable connection requires connecting the composite cable connector to the fibre port of the WNS as shown in Figure 15: Composite cable connector and Fibre port. Once the WNS is connected, it will auto detect devices and their settings.
Installation
Figure 15: Composite cable connector and Fibre port
The following procedure outlines composite cable connection when there is power being supplied downstream in the network.
Important: Protect all connectors and sockets from dust and grit, with minimal exposure during installation. Any unused sockets must be covered by the supplied dust caps at all times.
1. Remove the dust cap from the fibre port socket.
Wireless Network Switch User Manual35Revision A
Installation
2. Align the composite cable connector to the locating notch on the fibre port socket as shown in Figure
15: Composite cable connector and Fibre port and insert firmly.
3. Screw the outer sleeve of the composite cable connector securely to the fibre port socket. The power LED will turn on, and corresponding fibre port link LED will light up green. The port activity LED will flash with network activity.
4. Repeat step 2 and 3 for connecting downstream cables.
5. If a WNS is installed at the other end of the downstream cable, the fibre link LED will light up green.
The fibre activity LED will flash with network activity.
Connecting a WNS to a branch WNS requires simply connecting composite cables to the additional fibre ports. The connected fibre ports will cause the corresponding fibre port LEDs to become active. If you are adding WNS units to an existing system, please consult your MST System Engineer to ensure power requirements are being met.

3.7 Connecting Ethernet Cable to the Wireless Network Switch

The external Ethernet ports are located on the underside of the WNS, and are used to connect to Ethernet devices (such as Laptop computers, Ethernet controlled PLCs, hard-wired Ethernet Phones and IP video devices). An Ethernet cable with a RJ45 connector is used to connect PoE devices. Ethernet cables are required to meet specifications for use in a mining environment in Ethernet Cable Specifications on page

Understanding VLANs

Topics:
Understanding Trunk and
Access Ports
VLANs and Wireless Networks
Native VLAN
This chapter explains the principles behind a Virtual Local Area Network (VLAN). It is important to understand VLANs to properly configure a WNS.
A VLAN is a collection of nodes grouped according to their function or application, rather than their physical location. They are grouped in order to separate and prioritise data within a network, as shown in
Figure 16: VLANs. VLANs are created when multiple applications,
such as voice, telemetry, data and video, are required in a mining network.
Figure 16:VLANs
Wireless Network Switch User Manual43Revision A
Understanding VLANs

4.1 Understanding Trunk and Access Ports

VLANs can be assigned to trunk ports and access ports on a network. These two types of port allocations determine how data is transmitted and relayed.

4.1.1 Trunk Ports

Trunk ports provide a connection between network switches and access points, and can be assigned to multiple VLANs. They will only transmit frames (packets of data) that belong to the port's assigned VLANs. To identify the frames, a network switch will add a tag to the frame (known as 802.1q trunking). The tag contains the following information:
VLAN ID — allows the network switch receiving a frame to identify the VLAN it belongs to.
Priority ID — allows the network switch to prioritise distribution when multiple frames are being transmitted. Priority ID ranges from 0-7, where 7 is the highest priority.
When a network switch receives a tagged frame, the tag is read to determine the VLAN it belongs to. The tag is removed and distributed to devices connected on the same VLAN. If a tagged frame is sent to a trunk port with a different VLAN ID not assigned to the port, it will be dropped.
When the network switch receives multiple frames, it will prioritise the distribution of frames based on the Priority ID in the VLAN ID tag. For more information on configuring VLANs, see Defining VLANs on page 63.

4.1.2 Access Ports

Access ports connect client devices such as PCs and laptops to the network switch, and can only be assigned to a single VLAN. Access ports can only send and receive untagged frames belonging to the assigned VLAN. Any tagged frames sent to an access port will be dropped.
An example of VLAN traffic flow through trunk and access ports is shown in Figure 17: VLAN traffic
flow and described below.
Revision A44Wireless Network Switch User Manual
Understanding VLANs
Figure 17:VLAN traffic flow
1. A PC sends an untagged frame on access port 10 (Control VLAN) on WNS 1. The frame is sent to
other access ports on the Control VLAN (access port 9).
2. WNS 1 tags the frame with VLAN ID = 4 and Priority = 5 and sends it through the trunk ports to WNS
2.
3. WNS 2 receives the tagged frame, and identifies the frame belonging to the Control VLAN.
4. WNS 2 removes the tag and sends the frame to all ports on the Control VLAN (access ports 9 and 10).
5. If WNS 1 receives multiple frames, they are tagged and sent via trunk ports to WNS 2.
6. WNS 2 receives the frames and prioritises distribution.

4.1.3 Port Allocation

Physical ports on the WNS can be configured to be either a trunk port or access port using the web browser interface or editing site configuration files when T ri vial File Transfer Protocol (TFTP) is used. The WNS default configuration has ports 1-4 and 9-12 allocated as trunk ports. Ports 1-4 are usually connected to other WNS units, and ports 9-12 are connected to WAPs or other PoE devices. For more information on configuring ports and VLAN membership, see Configuring the VLAN Port Map on page 65.

4.2 VLANs and Wireless Networks

The WNS can hav e up to four wireless Service Set Identifiers (SSIDs) per WA C. Each SSID is associated with a single VLAN and functions as an access port on that VLAN. An example of a wireless network is shown in Figure 18: An example of VLAN and wireless networks and described below.
Wireless Network Switch User Manual45Revision A
Understanding VLANs
Figure 18: An example of VLAN and wireless networks
1. An untagged frame is sent from a Laptop 1 through a wireless network (SSID = Data) on the WNS.
2. The frame is tagged by the WNS and is sent through the trunk port to the WAP.
3. The WAP identifies the tagged frame as belonging to the Data VLAN and removes the tag.
4. The untagged frame is sent via the wireless network (SSID = Data) to Laptop 2.

4.3 Native VLAN

Trunk ports on a WNS also support a Native VLAN. The Native VLAN is where untagged frames will be allocated. On the WNS, the nativ e VLAN is always the Infrastructure VLAN. This allo ws client devices such as PCs or laptops to access and manage a WNS when they are connected via a trunk port.
The Infrastructure VLAN is mandatory in the WNS and cannot be deleted. An example of native VLAN functionality is illustrated in Figure 19: An example of native VLAN and
described below.
Revision A46Wireless Network Switch User Manual
Understanding VLANs
Figure 19: An example of native VLAN
1. The PC sends an untagged frame to Trunk port 3 on WNS 1.
2. The frame is allocated to the Infrastructure VLAN.
3. The management CPU of WNS 1 is always an Access port on the Infrastructure VLAN and will receiv e
the frame.
4. The untagged frame would also go to WNS 2 via the Trunk ports between the WNS units.
5. WNS 2 allocates the untagged frame to the Infrastructure VLAN.
6. The management CPU of WNS2 is always an Access port on the Infrastructure VLAN and will recei ve
the frame.
7. Any frame leaving the Management CPU is placed on the Infrastructure VLAN.
8. All frames on the Infrastructure VLAN are sent out untagged on Trunk ports.

Centralised Configuration Management

6.1 Overview

Centralised configuration management involves the following steps:
1. Configure a TFTP server on the network.
2. Define a site configuration file which contain global settings to all network devices on the site.
3. Define device configuration files which contain specific settings for each device, which o verride global
settings.
4. Applying the configuration files to each device and rebooting. Network devices read and apply the configuration files from the TFTP server as shown in Figure 45:
Centralised configuration management .

Device configuration files contain settings specific to each WAC in the network device. A device configuration file is created for each WAC. Device configuration files follow the naming convention ap_MACaddress.conf where MACaddress is the MAC address of the WAC. A device will recognise and apply the device configuration file based on a comparison of the MAC address in the file name.
Note that any parameter from the site configuration file can override parameters in a de vice configuration file. However, it is recommended that only the settings that are different be entered into the device configuration file in order to make maintenance easier.

6.5 Editing Device Configuration Files

A device configuration file configures individual settings for each device as shown below. The device configuration file can be edited using a text editor such as Wordpad or Notepad. The example below includes settings that are commonly over-ridden. All other settings are inherited from the global site configuration file.
# Mine Site Technologies Wireless Network Switch Config File
# System # ====== # system.hostname='AP57R2' system.location="Mine Location 16"
# Network # ======= # network.addr=192.168.0.247
# Wireless Radio Configuration # ============================ # wireless.radio.channel = 11
# Feature Activation # ================== # #system.activation_code='f085f3f2-6a55f34a-8cacf508-c64e98bd-0c95136f'
The parameters shown in the example device configuration file are described in the following table.
SettingsDescriptionParameterSection
Network switch name.system.hostnameSystem
Each device should have a unique name identifier.
system.locationSystem
Location name of the network switch.
It is recommended the location name is relevant to the physical location of the device.
network.addrNetwork
IP address of the WAC in the network switch.
Every WAC will be assigned a unique IP address.

To edit a device configuration file:
1. Open a text file editor on your PC.
2. Locate and open the device configuration file ap_MACaddress_settings.conf. This is usually stored
in the file directory folder of the TFTP server.
3. Edit the parameters as required.
4. In the directory folder of the TFTP server, save the file using the naming ap_MACaddress_settings.conf, where MACaddress is the MAC address of the WAC card to
configure.

6.6 Applying Configuration Files

To apply configuration files to a network switch:
1. Connect a PC to the network or network switch. Refer to Connecting a PC to an ImPact Network
Device on page 107 for more information.
2. Check the TFTP server is connected and running on the same network as the network device. If the TFTP server is being run on the PC, open the TFTP server application.
3. Open a Telnet software utility on your computer. For a PC with Windows OS, open the command prompt.
4. T ype T elnet xxx.xxx.xxx.xxx (where xxx.xxx.xxx.xxx is the IP address of the WAC card in the ImP act network device to be updated). The login screen will be displayed.
