STEP 3 Choose the Network Type:

• Infrastructure—The WBPN is connected to the wireless network through a

wireless router or access point (AP).

• Ad-hoc—The WBPN directly communicates with other devices in the ad-

hoc network. Each device must be configured with the same SSID and
channel number in order to communicate with other devices in the ad-hoc
network.

STEP 4 If you chose the ad-hoc network type, you can configure the following parameters:

• Channel width—Choose to manually configure the channel bandwidth for

Wireless-N connections. When it is set to 20MHz, only the 20MHz channel is
used. When it is set to 40MHz, Wireless-N connections will use the 40MHz

but can slow traffic. Choose a key format (ASCII or hexadecimal) and enter a
passphrase or key in the Encryption Key field. Hexadecimal format is more
secure.

• WPA/PSK or WPA2/PSK—Wi-Fi Protected Access/pre-shared key

encryption. Either of these encryption types is more secure than WEP and is
recommended instead of WEP. There are two encryption options for WPA/
PSK: TKIP (Temporal Key Integrity Protocol) and AES (Advanced Encryption
System). TKIP utilizes dynamic keys and incorporates Message Integrity
Code (MIC) to provide protection against hackers. AES uses a symmetric
128-bit block data encryption. WPA2 uses AES-CCMP to perform user
authentication, which uses a symmetric 128-Bit block data encryption.
Choose the pre-shared key format (passphrase or hexadecimal) and enter
the pre-shared key in the field. Hexadecimal format is more secure.

Configuring Advanced Settings

To configure advanced wireless settings, from the Navigation Menu, choose
Wireless > Advanced Settings. You can configure the following settings:

Fragmentation
Threshold

RTS Threshold “Request to send” threshold. If you configure Request

This value specifies the maximum size for a packet
before data is fragmented into multiple packets. If you
experience a high packet error rate, you can slightly
increase the Fragmentation Threshold. Setting the
Fragmentation Threshold too low may result in poor
network performance. Only minor reduction of the
default value is recommended. In most cases, it should
remain at its default value.

to Send/Clear to Send (RTS/CTS) on the WBPN, the
RTS threshold is the packet size included in the
request. You can configure this value if the WBPN has
inconsistent data flow. Only minor reduction of the
default value, 2347, is recommended. The RTS
Threshold value should normally remain at the default
value of 2347.

Cisco WBPN User Guide 26

Using the WBPN Wireless-N Bridge for Phone Adapters Configuration Utility

Configuring Wireless Parameters

Beacon Interval The Beacon Interval value indicates the frequency

interval of the beacon. The beacon is a packet
transmitted at regular intervals from APs in order to
synchronize the wireless network.

Preamble Type The preamble is at the head or front of the Physical

Layer Convergence Protocol (PLCP), which is one of
the parts of the wireless physical layer. Devices use the
preamble type to start transferring data.

Long—The long preamble ensures compatibility with
legacy 802.11b devices but can slightly reduce
throughput at high data rates.

Short—The short preamble reduces the header's size
by 50%, down to 9 bytes. The short preamble is
optional for 802.11b. The 802.11g and newer standards
all support the short preamble. If you do not have

802.11b devices in your network, you can enable the
short preamble for a small throughput increase.

2

Protection If you apply RTS/CTS flow control on the

communication with wireless LAN handsets, choose
Enabled to improve communication speed. If you have
few wireless LAN handsets, choose Disabled.

Aggregation With frame aggregation, up to 64 MSDUs (MAC Service

Data Units, or Layer 2 frames) can be sent at one time.
This “super” frame has one physical layer header and
data frames (each with its own MAC header). Once all
the data has been sent, a block acknowledgment is
sent.

Enabling aggregation can help reduce bandwidth size
by reducing the “overhead” in networks with high
transmission rates, and allows higher throughput.

Short GI The guard interval (GI) is the space between symbols

(characters) being transmitted. The short guard interval
time is 400ns, which is half of the usual GI (800ns).
Enabling short GI helps throughput.

20/40MHz Coexist Allows data to be transmitted on both the 20 MHz and

40MHz channels of the wireless LAN.
