3.1 Overview
This chapter provides an overview of the possible topologies and step-by-step
hardware installation instructions.
The Evaluation Kit provides the ability to evaluate Metalink’s MtW8171 and
MtW8151 MIMO WLAN transceiver chipset. The chipset is packaged inside an
Evaluation Kit for a seamless evaluation. The kit is preconfigured to serve as either
an Infrastructure Station (STA) or as an Access Point (AP).
A typical installation consists of one AP, which is physically connected to a
PC/device serving as a Video Streamer on one end, and one or more STAs,
connected to PCs/devices serving as Video Receivers on the other end. The AP
Evaluation Kit transmits the video stream to the STAs using wireless
communication.
The connection between the Evaluation Kits and the Video Streamer/Receiver(s)
uses an Ethernet interface. The connection is supported for both Windows-based
and Linux-based Video Receivers and Video Streamers.
It is recommended to use the Evaluation Kits with their factory configurations.
These are clearly marked on a label which includes the following information:
AP <IP Address> - This Evaluation Kit is configured to serve as the Access Point
and its preconfigured IP address is marked.
STA <1/2/3> <IP Adress>- This Evaluation Kit is configured to serve as a
Station and its preconfigured IP address is marked.
To change the preconfigured settings, follow the instructions inChanging
Configuration Settings on page 25.

4.3 Advanced Settings
4.3.1 Advanced Wireless Settings
Parameter Description Values
Use LDPC Low-Density Parity-check Code. It
enables/disables error correction for
reducing the probability of data loss in
noisy channels. The Rate Adaptation
algorithm automatically disables LDPC
coding when working at high PHY
rates (higher than 162).
ERP Protection Type This feature allows protection of OFDM
packets despite the presence of
802.11b stations within the BSS. By
sending RTS/CTS or CTS2Self packets
in 802.11b rates, the device informs
the BSS that OFDM packets are going
to be transferred and protects the
packets in the BSS. The RTS/CTS and
CTS2Self creates overhead which may
result in lower throughputs.
The RTS/CTS option provides better
coverage compared to CTS-to-Self,
but results in lower throughputs. This
is caused by the fact that the
RTS/CTS option includes
acknowledgement from the receiving
device, while the CTS2Self option
does not.
Use Overlapping
BSS protection (AP
only)
This option enforces BSS protection
when the AP detects beacons from
overlapping 802.11b APs or
overlapping APs with the ERP bit
turned-on. In this case when the AP
will detect a beacon from an
overlapping BSS it will extend the
protection coverage to its BSS.
Yes - Uses LDPC

11n Protection Type This feature allows protection from
non-HT Stations within the BSS. In
case the AP detects an association of
a non-HT legacy STA, it will signal all
the HT STAs to use RTS/CTS or CTSto-Self mechanisms before each data
transmission. This feature also
supports all 802.11n standard
protections, including MIMO.
The RTS/CTS option provides better
coverage compared to CTS-to-Self,

without the need to configure
additional security settings.
When chosen, the AP does not
advertise the SSID of it’s BSS in the

4.3.4 Wi-Fi Protected Setup
Wi-Fi Protected Setup™ is an optional certification program from the Wi-Fi Alliance
that is designed to ease the task of setting up and configuring security on wireless
local area networks. WLANPlus features Wi-Fi Protected Setup, enabling the
seamless setup of the secured network. In WPS there are two types of devices:
Registrar – A logical entity with the authority to issue and revoke domain
credentials. In this case the Registrar is usually the AP.
Enrollee – A logical entity which receives the domain credentials from the
Registrar. In this case the Enrollee is usually a STA.
The WPS feature allows connection between a Registrar and an Enrollee using two
methods:
Personal Identification Number (PIN) – A multi-digit number that is
generated to enrol a specific client device on the WLAN.
Push Button Configuration (PBC) - A configuration method triggered by
pressing a physical/logical button on the enrolee device and on the registrar.
Configuring WPS via PIN
Setting a secured network connection between an AP and an STA using WPS via
PIN involves the following steps:
1. Enabling WPS in the AP and then in the STA.
2. Entering the STA’s PIN number in the AP and instructing the AP to configure the
STA.

5.1 Overview
This chapter describes two ways to stream video from the AP to the STA(s):
Unicast Streaming – a straightforward method for video streaming. The
WLANPlus evaluation kit CD-ROM includes a Unicast streaming program called
VideoLAN Media Player. VideoLAN is used for both streaming and receiving or
playing-back the video stream. Therefore, it should be installed on both the
Video Streamer and the Video Receiver. This method does not incorporate a
retransmission mechanism, and it is therefore more susceptible to video
glitches.
NFS Streaming – NFS is Linux's "Network File System". It may be used to
stream video. This method includes a retransmission mechanism, which reduces
its susceptibility to video glitches caused by link interferences.
5.2 Installing the VideoLAN Media Player
The VideoLAN Media Player should be installed on both the Video Streamer and the
Video Receiver. If you wish to stream to more than one station simultaneously, you
will need to run a different instance of VideoLAN Media Player to play each stream
separately.
To Install VideoLAN Media Player on the Video Streamer:
1. Insert the WLANPlus CD-ROM into the Video Streamer CD-ROM drive.
2. Open the VideoLAN folder.
3. Double click vlc-0.8.5-win32.exe
4. Follow the on-screen instructions.
For Linux-based Video Streamers, VideoLAN should be available as part of your
Linux distribution package. Refer to the OS documentation for installation
instructions.

7. Enter the Port number of the Video Receiver into the Port field. The default
number, “1234”, can be used unless you required otherwise.
8. Click OK.
9. In the Open window click Browse.
A file system window appears.
10. Select the file you wish to stream.
11. Click OK.

5.4 Receiving Video with VideoLAN Media Player
The video stream can be played back by a separate instance of VideoLAN Media
Player that is installed on the Video Receiver.
To run VideoLAN Media Player on the Video Receiver:
1. From the Start >Programs menu, select VideoLAN Media Player.
2. From the File menu select Open Network Stream.
The Open Network Stream window appears with the Network tab selected.
3. Select UDP/RTP (default).
4. Enter the Port number in the Port field. If you did not change the default value
on the Video Streamer’s port settings (1234), use the default value.
5. Click OK.
5.5 Setting VideoLAN Media Player for Multicast Mode
Considering that proper multicast configuration was set in the Evaluation Kit,
different configurations of the VLC are required.
To configure the VLC at the AP:
1. In the VLC program, click File > Open File and select a file to be streamed.
2. Click Settings, in the Send to a multicast field, enter the following multicast
address: 225.0.0.0 to 239.255.255.255
3. Under Miscellaneous, change the TTL (Time to Live) field to 4.
4. Click OK.
To configure the VLC at the STA:
1. In the VLC program, click File >Open Network Stream.
2. Under Settings, in the UDP/RTP Multicast field, enter the address as set in the
AP side as multicast.
3. Click OK.

5.6 Installing NFS
The NFS (Network File System) offers a good solution to streaming video over UDP
in problematic link interference conditions. To use NFS, you will need to install an
NFS Server on the Video Streamer, and an NFS Client on the Video Receiver.
Although instructions are given for Red Hat Linux systems, the information is
relevant for other Linux distributions as well.
To install an NFS server on a Linux-based Video Streamer:
1. From the Application menu, open System Settings and select Services.
The Services window appears.
2. Select the NFS checkbox.
3. Create a new directory (for example, "/shared"). This directory will be exported
to the NFS clients.
4. Locate the video file to be streamed and copy it into this directory.
5. To define the directories to be exported to the NFS clients and their access
rights, edit the /etc/exports file as follows: <path> <ip_mask> (permission,
access type)
For example:
#
/shared 10.10.*.*(ro,sync)
Available parameters:
Path (for example, /shared) - Name of the directory containing the video
files to be shared
IP Mask (for example, 10.10.*.*) - IP mask for addresses that are allowed
to access this directory
Permissions (for example, ro) - The access type for each IP mask
Access Type (for example, sync) - Specifies whether the access is
synchronous or asynchronous
6. For these changes to take affect do one of the following:
Restart the Video Streamer.
Call "/etc/rc.d/nfsserver restart" (this may not work on every Linux
distribution).
The NFS server is now installed.
To install and setup NFS Server on the a Windows-based Video Streamer:
1. Insert the WLANPlus CD-ROM into the Video Streamer CD-ROM drive.
2. Open the nfsAxe folder.
3. Double click the setup.exe file.
4. Follow the on-screen instructions.
5. Launch the NFS server from the Programs menu.
6. First time users only - Click Yes to create a list of exported directories.

7. In the NFS Server screen, click Export.
The NFS Settings screen appears:
8. Click Add Directory and select the directory you want to export.
Revision 2.3.5 Page 59 of 69

9. Select the directory, and click Add User Access.
The User Access window appears:
10. To restrict access enter one of the following:
A specific NFS Client Host
A specific User ID
A specific Group ID
TIP:
If you do not want to restrict access to the shared content, do not make
any changes and click OK.
11. Click OK.

12. In Server State select Resume.
The NFS Server is ready.
In order to access the folder exported by the NFS server, you need to perform a
“mount” operation.
To setup NFS Client on a Linux-based Video Receiver:
1. Create a local folder in the video receiver file system. This folder will be the
mount point. For example, the folder named can be called “/mounted”.
2. Call the “mount” command: mount –t nfs server-IP:/shared /mounted
The new folder is mapped to the remote folder “/shared” on the NFS server.
3. Try to access “/mounted” and check that you can see the files stored on the NFS
server under the folder “/shared”.
The procedure below describes a quicker method for performing mounts and
should be used to perform multiple “mounts”.
To setup NFS Client on a Linux-based Video Receiver to perform "multi-
mounts":
1. Open the /etc/fstab file.
2. Add the following line:
<server>:</path/of/dir> </local/mnt/point> nfs <options> 0 0
For example:
Server-IP:/shared /mounted nfs –o rsize=8192,wsize=8192,intr
3. Call the “mount” command: mount –a nfs server-IP:/shared /mounted
The new folder is mapped to the remote folder “/shared” on the NFS server.
4. Try to access “/mounted” and check that you can see the files stored on the NFS
server under the folder “/shared”.
