Chapter 2: Hardware Installation

To install the SMC Cradle Access Point, follow these steps:

1. Select a Site – Choose a proper place for the access point. In general, the best

location is at the center of your wireless coverage area, within line of sight of all
wireless devices. For optimum performance, consider these points:

• Mount the access point as high as possible above any obstructions in the
coverage area.

• Avoid mounting next to or near building support columns or other obstructions
that may cause reduced signal or null zones in parts of the coverage area.

• Mount away from any signal absorbing or reflecting structures (such as those
containing metal).

• Avoid radio interference by mounting away from other 2.4 GHz devices, such as
other 802.11b or g wireless devices, regular cordless phones, and microwave
ovens.

2. Mount the Access Point – The access point is designed to be mounted on any
horizontal surface, such as a desktop.

3. Connect the Power Cord – Connect the power adapter to the access point,
and plug the power adapter into an AC power outlet.

Warning: Use ONLY the power adapter supplied with the access point.

Otherwise, the product may be damaged.

4. Observe the Indicator LEDs – When you power on the access point verify that
the POWER LED turns on and that the other LED indicators start functioning as
described under “LED Indicators".

5. Connect the Ethernet Cable – The access point can be connected to any 10
or 100 Mbps Ethernet network device, such as a hub or a switch. Connect your
network to the RJ-45 port on the back panel using category 3, 4, or 5 UTP
Ethernet cable. When the access point and the connected device are powered
on, the INTERNET LED should turn on indicating a valid network connection. If
the INTERNET LED fails to turn on, refer to “Troubleshooting".

Chapter 3: Initial Configuration

The SMC Cradle Access Point offers a user-friendly web-based management
interface for the configuration of all the unit’s features. Any PC with a wired or
wireless connection to the unit can access the management interface using a web
browser, such as Internet Explorer (version 5.0 or above). The initial configuration
steps can be made through the web browser interface using the Setup Wizard.

Connecting to the Web Interface

It is recommended to make the initial changes by connecting to the web
management interface through a wired connection to the access point’s Ethernet
port using the default IP (Internet Protocol) address of 192.168.1.1. Alternatively,
you can connect to the web interface through a wireless connection. Either method
may require changing the IP address settings of the attached PC.

The following procedure shows how to access the web interface from a PC
connected to the access point’s Ethernet port:

1. Place the access point close to the PC that you will use for configuration. It

helps if you can see the front panel LEDs of the access point while working on
your PC.

AP’s Default IP Address 192.168.1.1

PC’s IP Address 192.168.1.x

Figure 3-1. Connecting to the Web Management Interface

2. Connect the network port of your PC to the access point’s Ethernet port, start

your PC (if it is not already running), connect power to the access point and,
when your PC has finished its start-up sequence, verify that you have a link by
checking the LEDs on the front-panel of the access point.

3. Set your PC’s IP address to be on the same subnet as the access point. The

default IP address of the access point is 192.168.1.1 and the subnet mask is

3-1

Initial Configuration

3

255.255.255.0, so the PC and access point are on the same subnet when they
both have addresses that start 192.168.1.x. If the PC and access point are
already on the same subnet, proceed directly to step 4. Otherwise, you must
manually set the PC’s IP address to 192.168.1.x (where “x” can be any number
from 2 to 254). If you are unfamiliar with this process, see “Changing a PC’s IP
Settings” below.

4. Open your web browser and enter the address http://192.168.1.1. If your PC is

properly configured, you will see the login page of your access point. If you do
not see the login page, check your settings and repeat step 3.

5. Proceed to the following sections for information on logging into the web

interface and starting the Setup Wizard.

Management Access Through a Wireless Connection

You can also access the web management interface from a PC using a wireless
connection. Follow these steps:

1. Ensure your PC is equipped with an 802.11g or 802.11b wireless adapter and

has a WLAN utility installed.

2. Set your PC’s IP settings so that it automatically obtains an IP address from the

access point. If you are unfamiliar with this process, see “Changing a PC’s IP
Settings” below.

3. Start your PC's WLAN utility and search for available wireless networks.

4. Find the wireless network named "SMC" and connect to it. (Be sure the access

point is already powered on and the WLAN LED is flashing.)

5. Open your web browser and enter the IP address 192.168.2.1 in the address

bar. The access point login page should display. If you do not see the login
page, check your PC's settings and repeat step 3.

Using the Setup Wizard

There are only a few basic steps you need to set up the access point and provide a
connection for your Wi-Fi phone and network access for other wireless stations.

The Setup Wizard takes you through configuration procedures for the general
network settings, such as IP configuration, wireless network name (Service Set
Identifier), and wireless security. Follow these steps:

1. Launch the Setup Wizard – Click “Start with Setup Wizard” on the home page.

2. Network Setting – Sets the access point’s IP address assignment method and

configures the local Dynamic Host Configuration Prototcol (DHCP) server and
Network Address Translation (NAT) settings.

Figure 3-4. Setup Wizard - Network Setting

There are three basic methods for configuring the access point’s IP address:

• Dynamic IP — The IP address is assigned automatically from a home
gateway router or other device that has a DHCP server feature.

• PPPoE — The IP address is assigned automatically from an Internet service
provider (ISP) through an ADSL modem using Point-to-Point Protocol over
Ethernet (PPPoE). If your ISP has provided you with a user name and
password, enter these in the corresponding text boxes under PPPoE Setting.

• Static IP — The IP address is assigned manually by the user. This may be
required if your access point is connected to a home gateway router or other
device that does not support a DHCP server.

3-6

Using the Setup Wizard

If you select Static IP, enter an appropriate IP address and subnet mask that are
compatible with your existing network. If a management station exists on
another network segment, then you must enter the IP address for a Default
Gateway that can route traffic between these segments. Also enter the IP
address for the Domain Name Server (DNS) to be used for host-name to IP
address resolution.

Figure 3-5. Setup Wizard - DHCP Server and NAT Settings

3. DHCP Server/NAT Setting — This access point includes a DHCP server that

can assign IP addresses to any wireless station or Wi-Fi phone requesting the
service. Addresses are assigned from a common address pool configured on
the access point. You can configure the address pool by specifying start and
end IP addresses.

3

NAT is a standard method of mapping multiple “internal” IP addresses to one
“external” IP address on devices at the edge of a network. For the access point,
the internal (local) IP addresses are the IP addresses assigned to wireless
clients by the DHCP server, and the external IP address is the IP address
assigned to the access point itself. Note that the access point IP address is
always in a different subnet from the DHCP server pool. The access point uses
the NAT IP settings to route traffic from the wireless interface to the Ethernet
network.

Note: When using a wireless client to access the web management interface with the

DHCP server enabled, be sure to change your PC’s IP settings to “Obtain an IP
address automatically” and then use the configured Gateway IP address (default:

192.168.2.1) in your web browser..

Wireless VAP 1 Setting – Sets the wireless Service Set Identifier (SSID) and

4.

wireless security encryption key for the VAP 1 network. An SSID is a
recognizable text name that identifies a wireless network. Wireless clients that
want to connect to a network through an access point must set their SSIDs to
match that of the access point.

This access point supports two independent wireless networks (SSID
interfaces) using the same radio. These SSID interfaces, or Virtual Access

3-7

Initial Configuration

3

Points (VAPs), enable wireless traffic to be separated for different user groups
within the same service area. Wireless clients within the service area connect to
what appears to be different access points, but is in fact the same physical unit.
For each SSID interface (or VAP) different security settings can be applied. This
allows you to set one SSID for public use and keep the other SSID private, or
restrict one SSID for Wi-Fi phones only and use the other for PC wiress data.

Figure 3-6. Setup Wizard - Setting the VAP 1 SSID and Security

Enter the SSID, or wireless network name, which all wireless stations must use
to associate with the access point. The SSID is case sensitive and can consist
of up to 32 alphanumeric characters (Default: SMC AP1).

The access point offers two wireless security options; Wired Equivalent Privacy
(WEP) or Wi-Fi Protected Access Pre-shared Key (WPA / WPA2-PSK). Select
the security you want to use and enter the appropriate encryption key, or select
“none” for no security.

• WEP Key — Enter 10 hexadecimal digits (0 to 9 and A to F) or 5
alphanumeric characters for 64 bit keys, 26 hexadecimal digits or 13
alphanumeric characters for 128 bit keys, and 32 hexadecimal digits or 16
alphanumeric characters for 152 bit keys.

• WPA / WPA2-PSK Key — Enter as an easy-to-remember form of letters and
numbers. The key must be from 8 to 63 characters, which can include
spaces.

System Settings

The system settings pages allow you to change the management access password
and restart the access point.

Administration

Management access to the access point is controlled through a single user name
and password.

To protect access to the management interface, you need to change the default use
name and password as soon as possible. If the user name and password are not
changed, then anyone having access to the access point may be able to
compromise the access point and network security.

Note: If you forget your user name or password, you can press the reset button on the

back of the access point for more than five seconds to reset to the factory
defaults.

changed. (Length: 0-16 characters, case sensitive)

• New Password – The password for management access. (Length: 0-16

characters, case sensitive)

• Confirm New Password – Enter the password again for verification.

• Country – Sets the country in which the access point is being used. Some

countries allow the user to set the access point so that it conforms to the local
wireless regulations. This setting ensures that the access point uses only the radio
channels and transmit power levels permitted for that region. It is the user’s
responsibility to set the correct country (the default is “NO_COUNTRY_SET”).
Once a country has been set, the Country setting is no longer displayed on this

Wireless VAP Settings

Wireless VAP Settings

The Wireless VAP 1 Setting (Default: Enabled) and Wireless VAP 2 Setting
(Default: Disabled) pages include configuration options for radio signal
characteristics and wireless security features on the access point.

The following sections apply to both Wireless VAP 1 Setting and Wireless VAP 2
Setting pages.

Basic

The Basic Setting page allows you to enable the VAP radio interface and define the
Service Set IDentifier (SSID).

The access point includes an IEEE 802.11g radio for wireless communications. The
IEEE 802.11g standard operates within the 2.4 GHz band at up to 54 Mbps. Note
that because the IEEE 802.11g standard is an extension of the IEEE 802.11b
standard, it allows clients with 802.11b wireless network cards to associate to an

802.11g access point.

The SSID is a recognizable text string that identifies the wireless network service
provided by the VAP interface. Wireless clients that want to connect to the network
must set their SSIDs to match that of the VAP interface.

4

Figure 4-8. Basic Wireless Settings

The displayed items on this page can be described as follows:

• Radio Status – Enables radio communications for the VAP interface.

(Default: VAP 1 - Enabled, VAP 2 - Disabled)

• Radio Mode – Defines the radio mode for the VAP interface. (Default: b+g mix)

- b only: Both 802.11b and 802.11g clients can communicate with the access
point, but 802.11g clients can only transfer data at 802.11b standard rates (up
to 11 Mbps).

- b + g mix: Both 802.11b and 802.11g clients can communicate with the access
point (up to 54 Mbps).

4-9

System Configuration

4

- g only: Only 802.11g clients can communicate with the access point (up to 54
Mbps). The g-only mode provides better wireless network performance, but

802.11b clients cannot connect to the access point.

• SSID – The name of the wireless network service provided by the VAP. Clients that
want to connect to the network must set their SSID to the same as that of the VAP
interface. (Defaults: VAP 1 - “SMC AP1,” VAP 2 “SMC AP2”; Range: 1-32
characters)

Channel Setting

The access point uses one radio channel in the 2.4 GHz band to communicate with its
clients. The radio channel may be set manually by the user or automatically by the
system, which selects the channel with the least radio interference.

Note: If you experience poor performance, you may be encountering interference from

another wireless device. Try changing the channel, as this may eliminate
interference and increase performance. Channels 1, 6, and 11, as the three
non-overlapping channels in the 2.4 GHz band, are preferred.

Figure 4-9. Wireless Channel Setting

The displayed items on this page can be described as follows:

• Auto Channel Selection – Enables the access point to automatically select an
interference-free radio channel. (Default: Enabled)

• Radio Channel – The radio channel that the access point uses to communicate
with wireless clients. When multiple access points are deployed in the same area,
set the channel on neighboring access points at least five channels apart to avoid
interference with each other. For example, you can deploy up to three access
points in the same area using channels 1, 6, 11. Note that wireless clients
automatically set the channel to the same as that used by the access point to which
it is linked. (Range: 1-11)

4-10

Wireless VAP Settings

WEP Security

The access point is configured by default as an “open system,” which broadcasts a
beacon signal including the configured SSID. Wireless clients with a configured
SSID of “any” can read the SSID from the beacon and automatically set their SSID
to allow immediate connection to the access point. To secure the wireless network,
you have to implement user authentication and wireless data encryption.

Wired Equivalent Privacy (WEP) provides a basic level of security, preventing
unauthorized access to the network and encrypting data transmitted between
wireless clients and the access point. WEP uses static shared keys (fixed-length
hexadecimal or alphanumeric strings) that are manually distributed to all clients that
want to use the network.

4

Figure 4-10. WEP Wireless Security

The displayed items on this page can be described as follows:

• WEP Status – Enables the access point to use WEP shared keys. If enabled, you

must configure at least one key for the VAP interface and all its clients.

• Key Type – Select the preferred method of entering WEP encryption keys on the

access point.

- Hexadecimal: Enter keys as hexadecimal digits (0 to 9 and A to F).

- Alphanumeric: Enter keys as alphanumeric characters.

• Setting Key – Sets WEP key values for one or two keys. At least one key must be

specified. Each WEP key has an index number. The selected key is used for
authentication and encryption on the VAP interface.

Enter key values that match the key type and length settings. Select 64 Bit, 128 Bit,
or 152 Bit key length. Note that the same size of encryption key must be supported
on all wireless clients. (Default: 64 Bit)

- 64 Bit: Enter keys as 5 alphanumeric characters or 10 hexadecimal digits.

4-11

System Configuration

4

- 128 Bit: Enter keys as 13 alphanumeric characters or 26 hexadecimal digits.

- 152 Bit: Enter keys as 16 alphanumeric characters or 32 hexadecimal digits.

Note: Key index and type must match that configured on all clients.

WPA-PSK Security

Wi-Fi Protected Access (WPA) employs a combination of technologies to provide an
enhanced security solution for wireless networks. The WPA Pre-shared Key
(WPA-PSK) mode for small networks uses a common password phrase that must be
manually distributed to all clients that want to connect to the network.

WPA2 is a futher security enhancement that includes the now ratified IEEE 802.11i
wireless security standard. Both WPA and WPA2 provide very robust security
through the support of the Advanced Encryption Standard (AES) and Temporal Key
Integrity Protocol (TKIP) encryption ciphers.

Note: The computationally intensive operations of AES encryption requires hardware

support on client devices. Before implementing AES in the network, be sure that
wireless client hardware is AES or WPA2 compliant.

Figure 4-11. WPA-PSK Wireless Security

The displayed items on this page can be described as follows:

• WPA-PSK Status – Enables WPA-PSK or WPA2-PSK security on the VAP
interface. When enabled, WEP clients are not supported. (Default: Disabled).

• Authentication – Selects the wireless security mechanism for the network.

- WPA-PSK – Use pre-shared key authentication for WPA-compliant clients.

- WPA2-PSK – Use pre-shared key authentication for WPA2-compliant clients.

- WPA Mix Mode – Use pre-shared key authentication for WPA- and

WPA2-compliant clients when they coexist in the same network.

• Key Cipher Mode – Selects the encryption cipher to use for multicast and unicast
data traffic:

- Auto – Uses TKIP for the multicast cipher and TKIP or AES for the unicast cipher

depending on the capability of associated clients.

- AES – Uses AES keys for both multicast and unicast encryption.

- TKIP – Uses TKIP keys for both multicast and unicast encryption.

4-12

Wireless VAP Settings

• WPA-PSK Key – Enter a key as an easy-to-remember form of letters and

numbers. The key must be from 8 to 63 characters, which can include spaces. All
wireless clients must be configured with the same key to communicate with the
VAP interface.

Network Settings

The access point supports DHCP client, DHCP server and Network Address
Translation (NAT). Point-to-Point Protocol over Ethernet (PPPoE) is also supported
for users that have an IP address assigned automatically from an Internet service
provider (ISP) through an ADSL modem.

DHCP Client

Configuring the access point with an IP address enables you to manage the access
point from any PC in the attached network. A number of access point features
depend on IP addressing to operate.

Note: You can connect to the web browser interface to access IP addressing only if the

access point already has an IP address that is reachable through your network.

By default, the access point is configured with the IP address 192.168.1.1, with the
DHCP client enabled.

Figure 4-12. DHCP Client Settings

The displayed items on this page can be described as follows:

• DHCP Client Setting – Enables the access point to automatically obtain an IP
address from a DHCP server. If a response is not received from the DHCP server,
the access point uses the fixed IP settings as configured on this page. When set to
disabled, a static IP address can be manually configured.

• Static IP Address – The IP address of the access point. Valid IP addresses
consist of four decimal numbers, 0 to 255, separated by periods.

• Subnet Mask – The mask that identifies the host address bits used for routing to
specific subnets.

• Default Gateway – The default gateway is the IP address of the router for the
access point, which is used if the requested destination address is not on the local
subnet. If you have management stations located on another subnet, type the IP

Network Settings

address of the default gateway router in the text field provided. Otherwise, leave
the address as (192.168.1.254).

• DNS IP Address – The IP address of a Domain Name Server on the network. A

DNS maps numerical IP addresses to domain names and can be used to identify
network hosts by familiar names instead of the IP addresses.

If you have a DNS server located on the local network, type the IP address in the
text field provided. Otherwise, leave the address as all zeros (0.0.0.0).

DHCP Server/NAT

The access point includes a Dynamic Host Configuration Protocol (DHCP) server
that can assign temporary IP addresses to wireless clients requesting the service.

Addresses are assigned to clients from a common address pool configured on the
access point. Configure an address pool by specifying start and end IP addresses.
Be sure not to include the access point's IP address in the address pool range.

Network Address Translation (NAT) is a standard method of mapping multiple
"internal" IP addresses to one "external" IP address on devices at the edge of a
network. For the access point, the internal (local) IP addresses are the IP addresses
assigned to wireless clients by the DHCP server, and the external IP address is the
IP address assigned to the Ethernet port. When enabled, the access point's wireless
interface uses the NAT IP settings to access the Ethernet network.

Note: When the DHCP server is enabled, NAT is also enabled.

Figure 4-13. DHCP Server/NAT Settings

The displayed items on this page can be described as follows:

• DHCP Server/NAT Setting – Enables or disables the DHCP server and NAT on

• Start/End IP Address – Specifies the start/end IP address of a range that the
DHCP server can assign to DHCP clients. You can specify a single address or an
address range.

• Gateway – The IP address of the gateway router for the access point, which is
used if the requested destination address is not on the local subnet.

• DNS IP Address – The IP address of a Domain Name Server on the network. A
DNS maps numerical IP addresses to domain names and can be used to identify
network hosts by familiar names instead of the IP addresses.

Note: With DHCP Server/NAT enabled, a wireless PC needs to use the configured

Gateway IP address (Default: 192.168.2.1) to access the web management
interface. With DHCP Server/NAT disabled, both wired and wireless PCs can use
the DHCP client setting (Default: 192.168.1.1).

PPPoE

Many Internet service providers (ISPs) use the Point-to-Point Protocol over Ethernet
(PPPoE) to automatically assign an IP address to users with a DSL modem. The
PPPoE page provides the settings needed for this service.

Figure 4-14. PPPoE Settings

The displayed items on this page can be described as follows:

• PPPoE Setting — Enables the access point IP address to be assigned
automatically from an Internet service provider (ISP) through an ADSL modem
using PPPoE.

• Username — If your ISP has provided you with a PPPoE user name, enter it in the
corresponding text box.

• Password — If your ISP has provided you with a PPPoE password, enter it in the
corresponding text box.

Time and Log

Time and Log

Simple Network Time Protocol (SNTP) allows the access point to set its internal
clock based on periodic updates from a time server (SNTP or NTP). Maintaining an
accurate time on the access point enables all system log messages to be stamped
with the correct time and date. If the clock is not set, the access point only records
the time from the factory default set at the last bootup.

The access point acts as an SNTP client, which periodically sends time
synchronization requests to a specific time server. SNTP uses Coordinated
Universal Time (or UTC, formerly Greenwich Mean Time, or GMT) based on the
time at the Earth’s prime meridian, zero degrees longitude. To display the time
corresponding to your local time, you must also indicate the number of hours your
time zone is located before or after UTC/GMT.

Figure 4-15. SNTP Settings

The displayed items on this page can be described as follows:

• SNTP Server Setting — Configures the access point to operate as an SNTP client.

When enabled, the time server IP address must be specified.

• Primary Server: The IP address of an SNTP or NTP time server that the access

point attempts to poll for a time update.

• Time Zone — Sets the number of hours your local time zone is located before or

after UTC/GMT. (Default: GMT+00)

• Daylight Saving — The access point provides a way to automatically adjust the

system clock for Daylight Savings Time changes. To use this feature you must
define the month and date to begin and to end the change from standard time.
During this period the system clock is set back by one hour.

Twisted-Pair Cable Assignments

For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires.
Each wire pair is identified by two different colors. For example, one wire might be
green and the other, green with white stripes. Also, an RJ-45 connector must be
attached to both ends of the cable.

Caution: Each wire pair must be attached to the RJ-45 connectors in a specific

orientation. (See “Straight-Through Wiring” on page B-2 and “Crossover
Wiring” on page B-2 for an explanation.)

Caution: DO NOT plug a phone jack connector into the RJ-45 port. Use only twisted-pair

Glossary

10BASE-T

IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3 or better
UTP cable.

100BASE-TX

IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5
or better UTP cable.

Access Point

An internetworking device that seamlessly connects wired and wireless networks.
Access points attached to a wired network, support the creation of multiple radio
cells that enable roaming throughout a facility.

Ad Hoc

A group of computers connected as an independent wireless network, without an
access point.

Advanced Encryption Standard (AES)

An encryption algorithm that implements symmetric key cryptography. AES provides
very strong encryption using a completely different ciphering algorithm to TKIP and
WEP.

Authentication

The process to verify the identity of a client requesting network access. IEEE 802.11
specifies two forms of authentication: open system and shared key.

Backbone

The core infrastructure of a network. The portion of the network that transports
information from one central location to another central location where it is unloaded
onto a local system.

Beacon

A signal periodically transmitted from the access point that is used to identify the
service set, and to maintain contact with wireless clients.

Broadcast Key

Broadcast keys are sent to stations using dynamic keying. Dynamic broadcast key
rotation is often used to allow the access point to generate a random group key and
periodically update all key-management capable wireless clients.

Glossary-1

Glossary

Dynamic Host Configuration Protocol (DHCP)

Provides a framework for passing configuration information to hosts on a TCP/IP
network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability
of automatic allocation of reusable network addresses and additional configuration
options.

Encryption

Data passing between the access point and clients can use encryption to protect
from interception and evesdropping.

Ethernet

A popular local area data communications network, which accepts transmission
from computers and terminals.

File Transfer Protocol (FTP)

A TCP/IP protocol used for file transfer.

Hypertext Transfer Protocol (HTTP)

HTTP is a standard used to transmit and receive all data over the World Wide Web.

IEEE 802.11b

A wireless standard that supports wireless communications in the 2.4 GHz band
using Direct Sequence Spread Spectrum (DSSS). The standard provides for data
rates of 1, 2, 5.5, and 11 Mbps.

IEEE 802.11g

A wireless standard that supports wireless communications in the 2.4 GHz band
using using Orthogonal Frequency Division Multiplexing (OFDM). The standard
provides for data rates of 6, 9, 12, 18, 24, 36, 48, 54 Mbps. IEEE 802.11g is also
backward compatible with IEEE 802.11b.

Infrastructure

An integrated wireless and wired LAN is called an infrastructure configuration.

Local Area Network (LAN)

A group of interconnected computer and support devices.

MAC Address

The physical layer address used to uniquely identify network nodes.

Network Time Protocol (NTP)

NTP provides the mechanisms to synchronize time across the network. The time
servers operate in a hierarchical-master-slave configuration in order to synchronize
local clocks within the subnet and to national time standards via wire or radio.

Glossary-2

Glossary

Open System

A security option which broadcasts a beacon signal including the access point’s
configured SSID. Wireless clients can read the SSID from the beacon, and
automatically reset their SSID to allow immediate connection to the nearest access
point.

Orthogonal Frequency Division Multiplexing (ODFM)

OFDM/ allows multiple users to transmit in an allocated band by dividing the
bandwidth into many narrow bandwidth carriers.

Service Set Identifier (SSID)

An identifier that is attached to packets sent over the wireless LAN and functions as
a password for joining a particular radio cell; i.e., Basic Service Set (BSS).

Session Key

Session keys are unique to each client, and are used to authenticate a client
connection, and correlate traffic passing between a specific client and the access
point.

Shared Key

A shared key can be used to authenticate each client attached to a wireless network.
Shared Key authentication must be used along with the 802.11 Wireless Equivalent
Privacy algorithm.

Simple Network Time Protocol (SNTP)

SNTP allows a device to set its internal clock based on periodic updates from a
Network Time Protocol (NTP) server. Updates can be requested from a specific NTP
server, or can be received via broadcasts sent by NTP servers.

Temporal Key Integrity Protocol (TKIP)

A data encryption method designed as a replacement for WEP. TKIP avoids the
problems of WEP static keys by dynamically changing data encryption keys.

Trivial File Transfer Protocol (TFTP)

A TCP/IP protocol commonly used for software downloads.

Wi-Fi Protected Access

WPA employs 802.1X as its basic framework for user authentication and dynamic
key management to provide an enhanced security solution for 802.11 wireless
networks.

Glossary-3

Glossary

Wired Equivalent Privacy (WEP)

WEP is based on the use of security keys and the popular RC4 encryption
algorithm. Wireless devices without a valid WEP key will be excluded from network
traffic.

WPA Pre-shared Key (WPA-PSK)

WPA-PSK can be used for small office networks with a limited number of users that
may not need a high level of security. WPA-PSK provides a simple security
implementation that uses just a pre-shared password for network access.
