INSTALLATIO N CONSIDERATIONS

There are a number of factors that can impact the range of wireless devices.

1. Adjust your wireless devices so that the signal is traveling in a straight path, rather than at an angle.

The more material the signal has to pass through the more signal you will lose.

2. Keep the number of obstructions to a minimum. Each obs truction can reduce the range o f a w ireless

device. Position the wireless devices in a manner that will minimize the amount of obstructions
between them.

3. Building materials can have a large impact on your wireless signal. In an indoor environment, try to

position the wireless devices so that the signal passes through less dense material such as dry wall.
Dense materials like metal, solid wood, glass or even furniture may block or degrade the signal.

4. Antenna orientation can also have a lar ge impact on your wireless signal. Use the w ireless adapter’s

site survey tool to determine the best antenna orientation for your wireless devices.

5. Interference from devices that produce RF (radio frequency) noise can also impact your signal.

Position your wireless devices away from anything that generates RF noise, such as microwaves,
radios and baby monitors.

6. Any device operating on the 2.4GHz frequency will cause interference. Devices such as 2.4GHz

cordless phones or other wireless remotes operating on the 2.4GHz frequency can potentially drop
the wireless signal. Although the phone may not be in use, the base can still transmit wireless
signal. Move the phone’s base station as far away as possible from your wireless devices.

If you are still experiencing low or no signal consider repositioning the wireless devices or installing
additional access points. The use of higher gain antennas may also provide the necessary coverage
depending on the environment.

wireless network.

To protect your privacy, use the wireless security mode to configure the wireless security features.
The Wireless tab provides the following configuration options: Basic, Advanced, MAC Filter, Security,

WPS and Station List.

WIRELESS BASIC

Repeater Mode Support

Repeater Mode Support allows you to “repeat” a wireless signal from an existing access point.
Select the radio button to enable or disable. When enabled you have the option of defining the specific

access point to repeat off of by entering in the remote access points or wireless router’s wireless MAC
address into the “AP MAC Addr. (Optional)” field. You must also configure the TEW-637AP with the
same SSID, channel and wireless encryption settings of the remote access point.

Page 20

To repeat Wireless N Router’s signal, enter its

wireless MAC address into “AP MAC Addr.” field

Wireless Mode

If all of the wireless devices you want to connect with this Access Point can connect in the same
transmission mode, you can improve performance slightly by choosing the appropriate "Only" mode. If
you have some devices that use a different transmission mode, choose the appropriate "Mixed" mode.

Network Name (SSID)
When you are browsing for available wireless networks, this is the name that will appear in the list (unless

Broadcast Network Name is set to Disable, see below). This name is also referred to as the SSID. For
security purposes, it is highly recommended to change from the pre-configured network name.

Multiple SSID #

This Access Point support multiple SSID function, you can assign three more SSID for this device.

Broadcast Network Name (SSID)

This option allows you to hide your wireless network. When this option is set to enable, your wireless
network name is broadcast to anyone within the range of your signal. If you're not using encryption then
they could connect to your network. When this mode is disabled, you must enter the Wireless Network
Name (SSID) on the client manually to connect to the network.

Frequency (Channel)

A wireless network uses specific channels in the wireless spectrum to handle communication between
clients. Some channels in your area may have interference from other electronic devices. Choose the
clearest channel to help optimize the performance and coverage of your wireless network.

WDS Mode

When WDS is enabled, this access point functions as a wireless bridge and is able to wi relessly
communicate with other access points via WDS links. A WDS link is bidirectional; both end points must
support WDS and each access point must know the MAC Address of the other. Each access point will be
configured with the remote access point’s MAC address and vice versa. Make sure all access points are
configured with the same SSID, channel and wireless encryption settings.

Page 21

Operating Mode

If you have both 11g and 11n client devices included on your wireless network at the same time, you
should choose Mixed Mode. And if you only have 11n client devices on your wireless network, you can
choose Green Field to enjoy high throughput.

Channel Bandwidth

The "20/40” MHz option is usually best. The other option is available for special circumstances.

Guard Interval

Using “Auto” option can increase throughput. However, it can also increase error rate in some install ations,
due to increased sensitivity to radio-frequency reflections. Select the option that works best for your
installation.

MCS

This parameter represents transmission rate. By default (Auto) the fastest possible transmission rate will
be selected. You have the option of selecting the speed if necessary.

Reserve Direction Grant (RDG)

Disable or enable reserve direction grant. Default is enabled.

Extension Channel

When 20/40 channel bandwidth has been chosen, you should select extension channel to get higher
throughput.

Aggregation MSDU (A-MSDU)

Disable or enable aggregation MSDU. Default is disabled.

Auto Block ACK

Disable or enable auto block ACK. Default is enabled.

Decline BA Request

Disable or enable decline BA request. Default is disabled.

Page 22

WIRELESS ADV ANCED

Beacon Interval

Beacons are packets sent by a wireless Access Point to synchronize wireless devices. Specify a Beacon
Period value between 20 and 1000. The default value is set to 100 milliseconds.

Fragment Threshold

This setting should remain at its default value of 2346. Setting the Fragmentation value too low may result
in poor performance.

RTS Threshold

This setting should remain at its default value of 2347. If you encounter inconsistent data flow, only minor
modifications to the value are recommended.

Preamble Type: Long Preamble / Short Preamble

The radio preamble is a section of data at the head of the Physical Layer Convergence Protocol that
contains information that the device and client devices need when sending and receiving packets.
The 18 byte ("long preamble") preamble is used to signal "here is a train of data coming" to the receiver.
The 802.11b standard gives an option of reducing the size of the PLCP preamble to 9 bytes ("short
preamble"), this significantly increases the throughput performance at higher data rates.
One downside to the PLCP is that the PLCP preamble and header is always transmitted at 1Mbps,
regardless of the transmission rate for the rest of the data. This means that the t ransfer time i s cons tant a t
192 Usec (microseconds) for the PLCP with long preamble. The short prea mble version does a li ttle better,

Page 23

transmitting the shorter preamble at 1Mbps and the header at 2Mbps, shortening the transmit time to 96
Usec.

IAPP(Inter-Access Point Protocol)

IEEE 802.11F or Inter-Access Point Protocol is a recommendation that describes an optional extension to
IEEE 802.11 that provides wireless access-point communications among multivendor systems.

The protocol is designed for the enforcement of unique association throughout an Extended Service
Setand for secure exchange of station's security context between the current AP and the new AP during
the handoff period. Based on security level, communication session keys between Aps are distributed by
a RADIUS server. The RADIUS server also provides a mapping service between AP’s MAC address and
IP address.

Protection

These protection mechanisms ensure that a STA that is a potential interferer defers any transmission for a
known period of time. These mechanisms are used to ensure that non-ERP STAs do not interfere with
frame exchanges using ERP PPDUs between ERP STAs and that non-HT STAs do not interfere with
frame exchanges using HT PPDUs between HT STAs, thereby allowing non-ERP and/or non-HT STAs to
coexist with ERP and/or HT STAs.

Frame aggregation

Frame aggregation is a feature of the IEEE 802.11e and 802.11n wireless LAN standards that increases
throughput by sending two or more data frames in a single transmission. Ev ery frame transmitted by an

802.11 device has a significant amount of overhead, including radio level headers, media access control

(MAC) frame fields, interframe spacing, and acknowledgment of transmitted frames. At the highest data
rates, this overhead can consume more bandwidth than the payload data frame. To address this issue,
the draft 802.11n standard defines two types of frame aggregation: Mac Service Data Unit (MSDU)
aggregation and MAC Protocol Data Unit (MPDU) aggregation. Both types group several data frames into
one large frame. Because management information needs to be specified only once per frame, the ratio of
payload data to the total volume of data is higher, allowing higher throughput.

MSDU aggregation

MSDU aggregation relies on the fact that most mobile access points and most mobile client protocol
stacks use Ethernet as their "native" frame format. It collects Ethernet frames to be transmitted to a single
destination and wraps them in a single 802.11n frame. This is efficient because Ethernet headers are
much shorter than 802.11 headers.

MPDU aggregation

MPDU aggregation also collects Ethernet frames to be transmitted to a single destination, but it wraps
each frame in an 802.11n MAC header. Normally this is less efficient than MSDU aggregation, but it may
be more efficient in environments with high error rates, because of a mechanism called block
acknowledgement. This mechanism allows each of the aggregated data frames to be individually
acknowledged or retransmitted if affected by an error.

Guard interval

In telecommunications, guard intervals are used to ensure that distinct transmissions do not interfere with
one another. These transmissions may belong to different users (as in TDMA) or to the same user (as in
OFDM). The standard symbol guard interval used in 802.11 OFDM is 0.8μs. To increase data rate,

802.11n added optional support for a 0.4μs guard interval. This provides an 11% increase in data rate.

Short GI (Shorter guard interval)

The shorter guard interval results in a higher packet error rate when the delay spread of the channel
exceed the guard interval and/or if timing synchronization between the transmitter and receiver is not
precise. A scheme could be developed to work out whether a short guard interval would be of benefit a
particular link. To reduce complexity, manufacturers typically only implement a short guard interval as a
final rate adaptation step when the device is running at its highest data rate.

WLAN Partition

When two clients link to this AP, they won't be able to communicate with each other if the WLAN Partition
is enabled.

STBC (Space Time Block Coding)

A transmitter diversity technique of spreading the transmit signal over multiple antennas to improve
reception. STBC also incorporates FEC (Forward Error Correction) coding.

20/40MHz Coexist

The 20/40 BSS Coexistence element is used by STAs to exchange information that affects 20/40 BSS
Coexistence.

RF Output Power

Switch the RF output power strength(%).

APSD Capable (Automatic Power Save Delivery)

Automatic power save delivery is a more efficient power management method than legacy 802.11 Power
Save Polling. The literature includes an 802.11 Power Save Mode overview, an analysis of unscheduled
and scheduled automatic power save delivery (APSD) and a comparison of APSD versus 802.11 Power
Save Mode performance. Most newer 802.11 stations already support a power management mechanism
similar to APSD. APSD is very useful for a VoIP phone, as data rates are roughly the same in both
directions. Whenever voice data is sent to the access point, the access point is triggered to send the
buffered voice data in the other direction. After that the VoIP phone enters a doze state until next voice
data has to be sent to the access point.

MAC FILTER

The MAC address filter section can be used to filter network access by machines based on the unique
MAC addresses of their network adapter(s). It is most useful to prevent unauthorized wireless devices
from connecting to your network. A MAC address is a unique ID assigned by the manufacturer of the
network adapter.

Wireless MAC Filtering

When "Disable" is selected, MAC addresses are not used to control network access.

Add MAC Filtering Rule

Use this section to add MAC addresses to the list below.

MAC Address

Enter the MAC address of a computer that you want to control with MAC filtering. Computers that have
obtained an IP address from the router's DHCP server will be in the DHCP Client List. Select a device
from the drop down menu.

The rule of thumb:

In mixed mode, multicast key has to be TKIP, but unicast key can be different per stations.
In WPA or WPA2 only mode, unicast and multicast key can be only AES for WPA2, and TKIP
for WPA. (AES means the unicast and multicast key are all AES. TKIP/AES means multicast
is TKIP. But unicast can be AES or TKIP, which depends on the peer.)

SECURITY

SSID choice

Choose the SSID which need to implement security.

Security Mode

Unless one of these encryption modes is selected, wireless transmissions to and from your wireless
network can be easily intercepted and interpreted by unauthorized users.

Page 26

WEP

Key Length

Hex

ASCII

64-bit

10 characters

5 characters

128-bit

26 characters

13 characters

A method of encrypting data for wireless communication intended to provide the same level of privacy as
a wired network. WEP is not as secure as WPA encryption. To gain access to a WEP network, you must
know the key. The key is a string of characters that you create. When using WEP, you must determine the
level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer
key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using
characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange - alphanumeric
characters) format. ASCII format is provided so you can enter a string that is easier to remember. The
ASCII string is converted to HEX for use over the network. Four keys can be defined so that you can
change keys easily. A default key is selected for use on the network.

WPA/WPA2-Personal and Enterprise

Both of these options select some variant of Wi-Fi Protected Access (WPA) -- security standards
published by the Wi-Fi Alliance. The WPA Mode further refines the variant that the router should employ.

WPA/WPA2 Mode:

WPA is the older standard; select this option if the clients that will be used with the router only support the
older standard. WPA2 is the newer implementation of the stronger IEEE 802.11i security standard. With
the "WPA2" option, the router tries WPA2 first, but falls back to WPA if the client only supports WPA. With
the "WPA2 Only" option, the router associates only with clients that also support WPA2 security.

Cipher Type:

The encryption algorithm used to secure the data communication. TKIP (Temporal Key Integrity Protocol)
provides per-packet key generation and is based on WEP. AES (Advanced Encryption Standard) is a very
secure block based encryption. With the "TKIP and AES" option, the router negotiates the cipher type with
the client, and uses AES when available.

Group Key Update Interval:
The amount of time before the group key used for broadcast and multicast data is changed.

Page 27

WPA/WPA2-Personal

This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK).
Pre-Shared Key: The key is entered as a pass-phrase of up to 63 alphanumeric characters in ASCII
(American Standard Code for Information Interchange) format at both ends of the wireless connection. It
cannot be shorter than eight characters, although for proper security it needs to be of ample length and
should not be a commonly known phrase. This phrase is used to generate session keys that are unique
for each wireless client.

WPA/WPA2-Enterprise

This option works with a RADIUS Server to authenticate wireless clients. Wireless clients should have
established the necessary credentials before attempting to authenticate to the Server through this
Gateway. Furthermore, it may be necessary to configure the RADIUS Server to allow this Gateway to
authenticate users.
Authentication Timeout: Amount of time before a client will be required to re-authenticate.
RADIUS Server IP Address: The IP address of the authentication server.
RADIUS Server Port: The port number used to connect to the authentication server.
RADIUS Server Shared Secret: A pass-phrase that must match with the authentication server.

WPA/WPA2 mixed environment

For those WPA2 stations, they will use AES for unicast. For those WPA stations, they will use
TKIP for unicast. But for multicast all WPA and WPA2 stations have to use the same key, and
that will be TKIP, because WPA station only knows about TKIP, WPA2 is new standard, so it
is defined to backward support TKIP on multicast.

Page 28

WPS

You can setup security easily by choosing PIN or PBC method to do Wi-Fi Protected Setup.

WPS mode

Two WPS modes can be selected – PIN & PBC. If PIN is selected, you should enter PIN code of your
wireless client device to get wireless connection with this AP.
