  1. Wireless Networks for Extreme Environments

  2. The Process Plant of the Future

  3. Hotspot WiFi Coverage 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

  4. Cellular WiFi Coverage 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

  5. Client Bridge 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

  6. Network Bridge 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

  7. MESH Network 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.

  8. TelemetryData Acquisition over WiFi or MESH Network 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

  9. TelemetrySignal Mirror over WiFi or MESH Network 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

  10. Wireless Networking Unlocking Data from Hazardous Areas Standards - Based Wireless Technology. Innovative Product Development, Technical Design Capability Zone 1 & Zone 2 Solutions iWAP200 iWAP107

  14. iWAP200 Access Point or MESH Router Zone 2 & 21 certified MESH Ethernet or 802.11 a/b/g/ WiFi WLAN versions Energy limited antenna outputs for connection of any antenna or Extronics iANT200 antennas IP66 31L stainless steel enclosure Fibre or CAT5 Ethernet Options on power supply, lightning arrestor, enclosure heating and cooling

  15. iWAP300 Universal Access Point Enclosure System IP66 316L stainless steel enclosure Leading WLAN hardware vendors can be installed : Cisco, Motorola, Meru, Aruba, Firetide etc Fibre or CAT5 Ethernet Options on power supply, lightning arrestor and heaters Custom versions for bespoke hardware possible

  16. iSOLATE 500 Intrinsically Safe RF Galvanic Isolator • Protects against all known hazardous AC, DC and transient faults • Use with any standard antenna • For use in Zone 0, Zone 1, Zone 2 solutions • Makes any RF output intrinsically safe • For use with any standard wireless radio equipment: - Wifi Access Point - UHF RFID Reader • iSOLATE 500

  17. iSOLATE 500 Intrinsically Safe RF Galvanic Isolator • Apparatus certified not component ‘U’ certified: • No further assessment required by notified bodies • Any radio can be treated as a ‘black box’ • Simple installation; conventional wiring of RF connections using standard tools – no glands • Future proof solution – new wireless hardware installed without notified body assessment • Patent pending product, available to order now

  18. RF Cable Transit Allows an intrinsically safe RF connection to be connected through an explosion proof enclosure wall

  19. iANT100 Universal Omni Directional Increased Safety Antennas Zone 1 & 21 certified (Class I Div 1 pending) IP66 PTFE enclosure 2.4 GHz and 5 to 6 GHz versions 5 dBi gain 5 metre coax cable – longer length on request

  20. iANT200 Intrinsically Safe Antennas Series Zone 0 (Class I Div 1 pending) Range includes Omni Directional, Sector/Patch and Directional in various gains and RF patterns for optimum coverage. Dual band WiFi options available Can be connected to any suitably certified intrinsically safe circuit IP66 plastic enclosure

  21. Location Tracking - position by triangulation 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 accuracydepending on infrastructure

  22. Location TrackingPosition by Choke Point Detection 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

  23. Location Tracking Entrance & Exit Detection & Counting In locations such as entries and exits two Extronics Tag Exciters can be used together to detect direction of movement. “In” sequence A then B “Out” sequence B then A

  24. Location Tracking Position by Presence Detection This method of location of an Extronics WiFi tag or WiFi device is zone based. Hence only to the vicinity of a particular access point or location receiver

  25. iTAG100 - Active RFID WiFi Tag Zone 0 (Class I Div 1 pending) certified for all hazardous areas including gassy mines Small battery powered tag for tracking people and assets Motion sensor for tracking if an asset is mobile and for battery life enhancement Call button and temperature sensor options Up to 4 years battery life

  27. iCITE100 – Tag Exciter Zone 1 (Class I Zone 1 pending) 125KHz field up to 0.5 to 6.5 metres Can reprogram or activate/deactivate tags Can be chained to cover wide entrance & exits Applications include floor differentiation, entrance/exit monitoring, direction and precise location of people/assets

  28. Telemetry – Data Acquisition over GSM/GPRS Network 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

  29. Communication – Data, Voice and Video over WiFi or MESH Networks 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

  30. Product Development Roadmap Wireless Cameras • iCAM600 high end portable camera with stills and video capability, Bluetooth & WiFi • iCAM200 Fixed IP camera with optional WiFi

  31. Wireless Network Benefits • Complete mobility for people and plant • Improved working practice and convenience • Increased efficiency for production, maintenance and inspection • Improve operator safety • Track and locate assets
