Standalone configuration with access point

2.1 Network structures

The following article deals with the setting up of various network structures using access points and clients. A client is also an access point in client mode.
This configuration does not require a server and the access point does not have a connection to a wired Ethernet. Within its transmission range, the access point forwards data from one WLAN node to another.
The wireless network has a unique name. All the SCALANCE W700 devices exchanging data within this network must be configured with this name.
The gray area in the graphic symbolizes the wireless range of the access point.

Wireless access to a wired Ethernet network
2.1 Network structures
If one (or more) access points have access to wired Ethernet, the following applications are possible:
● A single device as gateway:
A wireless network can be connected to a wired network via an access point.
● Span of wireless coverage for the wireless network with several access points:
The access points are all configured with the same unique SSID (network name). All nodes that want to communicate over this network must also be configured with this SSID.
If a mobile station moves from the area covered by one access point to the area covered by another access point, the wireless link is maintained (roaming).
The following graphic shows the wireless connection of a mobile station over two wireless cells (roaming).

Description
Multichannel configuration
2.1 Network structures
If neighboring access points use the same frequency channel, this can lead to longer response times due to any collisions that may occur. If the configuration shown in the figure is implemented as a single-channel system, computers A and B cannot communicate at the same time with the access points in their wireless cells.
If neighboring access points are set up for different frequencies, this leads to a considerable improvement in performance. As a result, neighboring wireless cells each have their own medium available and the delays resulting from time-offset transmission no longer occur.
The channel spacing should be as large as possible; a practical value is 25 MHz. Even in a multichannel configuration, all access points can be configured with the same network name.
The following graphic shows a multichannel configuration on channels 1 and 2 with four access points.

IEEE 802.11n
Overview

2.4 IEEE 802.11n

The standard IEEE 802.11n is an expansion of the 802.11 standard and was approved in
2009. Previous standards worked either in the 2.4 GHz frequency band (IEEE 802.11g /b) or in the 5 GHz frequency band (IEEE 802.11a). IEEE 802.11n can operate in both frequency band. In the IEEE 802.11n standard, there are mechanisms implemented in PHY and MAC layers that increase the data throughput and improve the wireless coverage.
● MIMO antenna technology
● Maximum ratio combining (MRC)
● Spatial multiplexing
● Channel bonding
● Frame aggregation
● Accelerated guard interval
● Modulation and coding scheme
● Data throughput rates up to 450 Mbps (gross)
This is not possible on all SCALANCE W700 devices.

Description
MIMO antenna technology
Maximum ratio combining (MRC)
Spatial mutliplexing
2.4 IEEE 802.11n
MIMO (Multiple Input - Multiple Output) is based on an intelligent multiple antenna system. The transmitter and the receiver have several spatially separate antennas. The spatially separate antennas transmit the data streams at the same time. Up to four data streams are possible. The data streams are transmitted over spatially separate paths and return over different paths due to diffraction, refraction, fading and reflection (multipath propagation). The multipath propagation means that at the point of reception a complex, space- and time­dependent pattern results as a total signal made up of the individual signals sent. MIMO uses this unique pattern by detecting the spatial position of characteristic signals. Here, each spatial position is different from the neighboring position. By characterizing the individual senders, the recipient is capable of separating several signals from each other.
In a multiple antenna system, the wireless signals are received by the individual antennas and combined to form one signal. The MRC method is used to combine the wireless signals. The MRC method weights the wireless signals according to their signal-to-noise ratio and combines the wireless signals to form one signal. The signal-to-noise ratio is improved and the error rate is reduced.
With spatial multiplexing, different information is sent using the same frequency. The data stream is distributed over n transmitting antennas; in other words, each antenna sends only 1/n of the data stream. The division of the data stream is restricted by the number of antennas. At the receiver end, the signal is reconstructed. Due to the spatial multiplexing, there is a higher signal-to-noise ratio and a higher data throughput.

Description
Channel bonding
Frame aggregation
Accelerated guard interval
2.4 IEEE 802.11n
With IEEE 802.11n, data can be transferred via two directly neighboring channels. The two 20 MHz channels are put together to form one channel with 40 MHz. This allows the channel bandwidth to be doubled and the data throughput to be increased. To be able to use channel bonding, the recipient must support 40 MHz transmissions. If the recipient does not support 40 MHz transmissions, the band is automatically reduced to 20 MHz. This means that IEEE 802.11n can also communicate with IEEE 802.11a/b/g devices. The channel bundling is set on the "AP (Page 287)" WBM page with the "HT Channel Width [MHz]" parameter.
With IEEE 802.11n, it is possible to group together individual data packets to form a single larger packet; this is known as frame aggregation. There are two types of frame aggregation:
● Aggregated MAC Protocol Data Unit (A-MPDU)
With A-MPDU, multiple MPDU data packets with the same destination address are bundled and sent as one large A-MPDU.
● Aggregated Mac Service Data Unit (A-MSDU)
With A-MSDU, multiple MSDU data packets with the same destination address are chained together and sent.
The SCALANCE W devices support both types of frame aggregation. You make the settings on the WBM page "AP 802.11n (Page 285)".
The guard interval prevents different transmissions being mixed together. In telecommunications, this mixing is also known as intersymbol interference (ISI). When the send time has elapsed, a send pause (guard interval) must be kept to before the next transmission begins.
