IWLAN – Access Points IEEE 802.11n

Overview

■

Overview

The access points of the SCALANCE W700 product lines are

ideally suited for setting up Industrial Wireless LANs (IWLAN) for

2.4 GHz or 5 GHz. They can be used in all applications that re-

quire a high degree of operational reliability, even in extremely

harsh surroundings.

• High data rates (up to 450 Mbit/s in connection with Channel

Bonding) as per IEEE802.11n

• Reliable wireless link by using of MIMO technology (Multiple

Input, Multiple Output). For this, SCALANCE W access points

use up to three streams for simultaneous sending and

receiving.

• SCALANCE W700 Access Points are suitable for any appli-

cation: for outdoors with high requirements regarding

climactic conditions, for installing without a control cabinet

indoors, for installing in the control cabinet, and for an

extended range of environmental conditions.

• Reliable thanks to a rugged, impact-resistant enclosure,

protected from water and dust (up to IP65), resistant to shock,

vibration and electromagnetic fields, resistant to condensation

thanks to the use of coated PCBs

• Demanding applications with real-time and redundancy

requirements, such as PROFINET with PROFIsafe

• Conformant to standards through supporting IEEE802.11;

expanded software functions especially for use where

increased reliability is required, e.g. cyclic real-time data

traffic and very high-speed roaming (iPCF, iPCF-MC)

• Configuration support by means of wizards and online help;

easy management via Web server and SNMP

• Configuration and diagnostics using Web based

Management, Command Line Interface, and SNMP. Devices

and networks can be configured using STEP 7 (TIA Portal). For

cyclic monitoring, diagnostics and documentation (reporting)

in network mode, the SINEMA Server software is recom-

mended.

• Enabling of further functions using the KEY-PLUG swap

medium (iPCF, iPCF-MC, iREF)

• Fast replacement of devices if a fault occurs thanks to use of

optional KEY-PLUG/C-PLUG (Configuration Plug) swap

medium

■

Benefits

• Predictable data traffic (deterministic response) and defined

response times on the wireless link

• Reliable wireless link, e.g. by using MIMO technology and

monitoring the wireless link

• Cost savings by having only one wireless network both for

process-critical data and for non-critical communication

• Future-proof because all products are compatible with the

internationally recognized WLAN standard IEEE 802.11n,

suitable for license-free 2.4 GHz and 5 GHz frequency bands

(ISM bands)

• Implementation of data-intensive applications such as video

streaming

• Reduced operating costs, because there is no wear and tear

on rotating and moving plant sections

• Cost-effective connection to devices which are remote,

difficult to access or installed in hostile environments

• Investment protection because flexible feature expansions

(iFeatures) are possible by using the KEY-PLUG

Application

The access points of the SCALANCE W700 product line are de-

signed for both industrial use and for demanding climatic re-

quirements outdoors. Versions for the inexpensive integration in

cabinets or in machines are also available. They provide a reli-

able wireless link, redundancy mechanisms, and fast handover

of nodes from one access point to the next (roaming). This allows

processes to be monitored and loss of production due to ma-

chine downtimes to be avoided.

Industrial Wireless LAN (IWLAN) can also be used in time-critical

applications in factory automation (PROFINET IO) or for safety-

related signals (PROFIsafe).

Due to their high degree of protection (up to IP65) and extended

temperature range from -40 °C to +70 °C, the access points are

ideally suited for use outdoors. SCALANCE W products are sili-

cone-free and can therefore also be used in paint shops.

When using the RCoax cable (radiating cable), operation is par-

ticularly reliable in conveyor systems and all track applications

(e.g. storage and retrieval systems, suspended monorail).
