Your Challenges …

Increasing mobile employees’ efficiency

Ensuring Security and Privacy - even “on air”

Ease of use – even in an industrial environment Fast Hand-Over for

supporting employees’ campus mobility

Why Why Siemens?Siemens?


Scenario Highlights

Siemens Wireless solutions are the 2nd generation of wireless LAN – tailored to enterprise and industry needs.

Siemens Wireless integrates

seamlessly into mobile business

processes providing

unbeatable mobility

communication on campus’

The true promise of mobility isn’t about getting rid of cabling, it is about adding value by increasing efficiency and reducing costs.



Scenario: Situation Today

09:19 AM Shipment is damaged - “Where is John?”

09:47 AM John is finally informed. Nothing to repair - total loss. John went back to his office - catching the documentation tools.

10:38 AM John is back to his damaged goods. After 30 minutes the entire case is documented and the papers are ready to be sent.

11:17 AM John informs the customer and the insurance company.

Wasting resources, inefficient support of business processes, unpredictable and lousy manageable business situations



Scenario: Situation Tomorrow

09.19 AM Shipment is damaged – Call to Johns Wireless handset

09.20 AM John starts immediately his location and asset management application.

09.23 AM “Nothing to repair - total loss.” John documents the entire case

09.50 AM The entire documentation was done and directly sent wireless to his manager and the insurance company.

High efficient case management - through tightly integration of WLAN communication technology into business processes.

IWLAN – Designed for Industry

Requirements - Industry

IWLAN 802.11

Requirements - Office / Consumer

WLAN 802.11

Reservation of bandwidth for selected clients (e.g. PLC) guaranteed access to radio channel

Radio channel is „shared medium“, everybody has access

Communication cycles predictable for deterministic data traffic

Radio traffic prioritized, but not predictable

Cyclic monitoring of the wireless connection and fast warning to the process

Chopping of the wireless connection can be corrected manually

Redundant wireless operation on two separate frequency bands for increased availability

Availability has little influence on Total Cost of Ownership

Metal housing, vibration-resistant connectors and cables

Low-cost plastic housing,

plug-in cycles < 10

Degree of protection IP 65, -20°C with condensation for the harsh industrial environment and outdoor use

Operation at home and in the office

Security state-of-the-art with 802.11i, WPA and VPN

Easy installation

Security state-of-the-art Home: Price and easy installation more important!

Industrial certifications: ATEX (ex area), EMC, UL, FM

No need for higher requirement(CE, shock hazard protection)

Flexible application through 18 - 57 VDC, 100 – 240 VAC, Power-over-Ethernet

Power supply 100 VAC – 240 VAC

Fast installation and easy replacement in the case of failure (C plug)

Low price more important than fast device replacement in the case of failure

Ethernet, antenna cables, housing chemically resistant, halogen-free, silicon-free, flame-retardant

No need for certifications with higher requirements

Release for system operation Product price more important than system price
