• Why do we ‘need’ wireless ?• What are we waiting for ?• Organisational Challenges• What’s happening ?
Do we really need wireless ?
• NO.• Well, maybe it can help us…..
…. do all the things that we do today…….. easier !!
• Ease of Deployment:- Flexibility / Temporary / Mobility
Available today / soon….
• Basic process sensors (P, dP, T, DI, etc)• Cross discipline (vibration, corrosion, etc)• Ex: Zone 1, 2 or none
What are we waiting for ?
• All solutions not ready yet for prime-time• Limited vendor-choice à limited solution
choice• Proprietary à Not complying to any standard
- Upgrade costs- System- Engineering effort- Business case driven
• Maturity- Products- Organisations
Challenges (SPIES)
• Power• Interference
• Standardisation
• Security
• (Process) Environment
ANY NETWORK
AN ADAN AD
ANOTHER NETWORK
Wgateway
FENCE LINE
Wireless Space
Bad Boys Box
Organisational Challenges
• New technologyNew skills
No experienceNo standards / best practices
• Cross-discipline: IT in Process Automation• Organisational ownership• Services

Base radios - Gateways – Remote I/O – Access points
Field-Devices
Sensors (w/wl) – video – Ex-HMIs – RTLS – RFID – Guest laptops
Field-connectivity (specific for application):- Wired- 802.15.4- UWB- Wi-Fi- Specials (433, 868, 900 MHz, etc)
WAD
Switch
NMS/IDS(Wireless Access Domain)
Wireless Architecture
Transparent (any combination):- Wired- WiMAX- Wi-Fi- Specials (GSM, GPRS, Satellite, etc)
So, what’s happening ?
• Slow pick-up of deployments- one step at a time with a vision of where to go
• The Standardisation Dance- WiHart & ISA100.11a à different purposes- ISA100.11a-Draft2 vote failed- àà Merge WiHart into ISA100…..
- Ease of management- Simple infrastructure (one baseradio !)- Managed Coexistence / Interoperability
- Good progress !!!!!!- Support the drive for first-time-right-quality !!
