An isolated access point provides
WLAN coverage in a defined area.
Dependant upon the type of antenna
used and the environment in which it is
installed.
Useful to enable localities in a plant
where WLAN access is possible
Hotspot WiFi Coverage
Wireless Networks for Extreme Environments I Copyright Extronics Ltd 2013 4
Similar to example one in that it
involves installing several access
points with each ones coverage area
overlapping the other slightly.
Complete sites can be covered with
WLAN access allowing users to roam
from one cell to the next
automatically
Cellular WiFi Coverage

Many electronic automation and
control devices have an Ethernet or
RS232 port but no wireless
connectivity.
Simply adding a client bridge
enables these devices to be
connected to the WLAN
Client Bridge
Wireless Networks for Extreme Environments I Copyright Extronics Ltd 2013 6
Buildings on a plant will have
often have fixed LANs just for
connectivity between devices in
that location.
A wireless bridge offers an
economical solution to connect
together two areas of LAN by
means of a wireless link.
This avoids expensive trenching
and cabling or fibre costs
Network Bridge

A wired Ethernet backbone is
expensive to install due to trenching
and cabling or fibre costs over long
distances.
A wireless MESH network provides
an Ethernet back haul for WLAN
access points or other Ethernet
enabled devices such as CCTV
cameras.
MESH Network
Wireless Networks for Extreme Environments I Copyright Extronics Ltd 2013 8
In many cases valuable process
data is not being recorded due to
the high costs involved to cable
the sensors.
Data acquisition over a wireless
network means process values
can be economically transmitted
to the corporate network for
visualisation and storage

A wireless Signal Mirror can be
used where analogue or digital
signals need transmitting and
repeating to another location
economically over long distances
or on mobile equipment where the
use of slip rings is too expensive

At least three access points or
location receivers determine the
position of a tag.
Uses either the tags’ RSSI (received
signal strength indicator) or TDOA
(time difference of arrival) of the tag’s
radio signal
Allows calculation of the location to
between 3 to 10 metre accuracy
depending on infrastructure
Location Tracking - position by triangulation
Wireless Networks for Extreme Environments I Copyright Extronics Ltd 2013 21
In locations such as entries and exits
Extronics Tag Exciter causes the tag
to transmit.
It’s location is then known to be
within the field of the Exciter.
Used for floor differentiation, change
tags properties such as turning it off
or altering blink rate
Location Tracking Position by Choke Point Detection
Wireless Networks for Extreme Environments I Copyright Extronics Ltd 2013 22
In locations such as entries and
exits two Extronics Tag Exciters
can be used together to detect
direction of movement.

In some locations a WLAN or MESH
based network cannot provide a
solution due to the remoteness of the
location or the lack if installed WiFi
infrastructure.
In this instance our GSM/GPRS solution
utilises the mobile telephone networks
which offer coverage in almost all areas
of the world.
The data is measured stored locally by
the battery powered RTU and offloaded
on a regular basis using the GSM/GPRS
network

Industry standard WLAN’s can be used
for many communication applications.
e.g. mobile PC’s for data collection,
voice calling using the VoIP protocol
with “push to talk” functions to replace
conventional radios.
Visual communication by the use of
wireless CCTV cameras offers complete
visibility of plant for maintenance,
inspection and security
