About the ProSafe Wireless-N Access Point WNAP320

The ProSafe Wireless-N Access Point WNAP320 is the basic building block of a wireless

LAN infrastructure. It provides connectivity between wired Ethernet networks and

radio-equipped wireless notebook systems, desktop systems, print servers, and other

devices.

The wireless access point provides wireless connectivity to multiple wireless network devices

within a fixed range or area of coverage—interacting with a wireless network interface card

(NIC) through an antenna. Typically, an individual in-building wireless access point provides

a maximum connectivity area of about a 500-foot radius. The ProSafe Wireless-N Access

Point WNAP320 can support up to 64 users simultaneously in a range of several hundred

feet.

The ProSafe Wireless-N Access Point WNAP320 acts as a bridge between the wired LAN

and wireless clients. Connecting multiple wireless access points through a wired Ethernet

backbone can further increase the wireless network coverage. As a mobile computing device

moves out of the range of one wireless access point, it moves into the range of another. As a

result, wireless clients can freely roam from one wireless access point to another and still

maintain seamless connection to the network.

The autosensing capability of the ProSafe Wireless-N Access Point WNAP320 allows packet

transmission at up to 300 Mbps, or at reduced speeds to compensate for distance or

electromagnetic interference.

ProSafe Wireless-N Access Point WNAP320 Reference Manual

Supported Standards and Conventions

The ProSafe Wireless-N Access Point WNAP320 supports the following standards and

conventions:

• Standards compliance.The wireless access point complies with the IEEE 802.11 b/g

standards for wireless LANs, and is Wi-Fi certified for 802.11n standard.

• Full WPA and WPA2 support. The wireless access point provides WPA and WPA2

enterprise-class strong security with RADIUS and certificate authentication as well as

dynamic encryption key generation. The WPA-PSK and WPA2-PSK preshared key

authentication is without the overhead of RADIUS servers but with all of the strong

security of WPA.

• Multiple BSSIDs. The wireless access point supports multiple BSSIDs. When a wireless

access point is connected to a wired network and a set of wireless stations, it is called a

basic service set (BSS). The basic service set identifier (BSSID) is a unique identifier

attached to the header of packets sent over a WLAN that differentiates one WLAN from

another when a mobile device tries to connect to the network.

The multiple BSSID feature allows you to configure up to eight SSIDs on your wireless

access point and assign different configuration settings to each SSID. All the configured

SSIDs are active, and the network devices can connect to the wireless access point by

using any of these SSIDs.

• DHCP client support.DHCP provides a dynamic IP address to PCs and other devices

upon request. The wireless access point can act as a client and obtain information from

your DHCP server; it can also act as a DHCP server and provide network information for

wireless clients.

• SNMP Support.Support for Simple Network Management Protocol (SNMP)

Management Information Base (MIB) management.

• 802.1Q VLAN (virtual LAN) support. A network of computers that behave as if they are

connected to the same network even though they might actually be physically located on

different segments of a LAN. VLANs are configured through software rather than

hardware, which makes them extremely flexible. VLANs are very useful for user and host

management, bandwidth allocation, and resource optimization.

Key Features

The ProSafe Wireless-N Access Point WNAP320 provides solid functionality, including the

following features:

• Multiple operating modes:

-Wireless access point. Operates as a standard 802.11b/g/n wireless access point.

-Point-to-point bridge. In this mode, the wireless access point communicates only

with another bridge-mode wireless station or wireless access point. Network

authentication should be used to protect this communication.

-Point-to-multipoint bridge. Select this only if this wireless access point is the master

for a group of bridge-mode wireless stations. The other bridge-mode wireless stations

Chapter 1. Introduction |9

ProSafe Wireless-N Access Point WNAP320 Reference Manual

send all traffic to this master, and do not communicate directly with each other.

Network authentication should be used to protect this traffic.

-Wireless repeater. In this mode, the wireless access point does not function as an

access point but communicates only with wireless stations that function in repeater

mode, point-to-point bridge mode, and point-to-multipoint-bridge mode. Network

authentication should be used to protect this communication.

-Client. In this mode, the wireless access point functions as a client bridge only, and

sends all traffic to a remote wireless access point or peer device.

• Hotspot settings. You can allow all HTTP (TCP, port 80) requests to be captured and

redirected to the URL you specify.

• Upgradeable firmware. Firmware is stored in a flash memory. You can upgrade it easily,

using only your Web browser, and you can upgrade it remotely. You can also use the

command-line interface.

• Rogue AP detection.The Rogue AP filtering feature ensures that unknown APs are not

given access to any part of the LAN.

• Access control.The Access Control MAC address filtering feature can ensure that only

trusted wireless stations can use the wireless access point to gain access to your LAN.

• Security profiles.When using multiple BSSIDs, you can configure unique security

settings (encryption, SSID, and so on) for each BSSID.

• Hidden mode. The SSID is not broadcast, assuring only clients configured with the

correct SSID can connect.

• Configuration backup. Configuration settings can be backed up to a file and restored.

• Secure and economical operation. Adjustable power output allows more secure or

economical operation.

• Power over Ethernet. Power can be supplied to the wireless access point over the

Ethernet port from any 802.3af-compliant midspan or end-span source.

• Autosensing Ethernet connection with Auto Uplink™ interface. Connects to

10/100/1000 Mbps IEEE 802.3 Ethernet networks.

• LED indicators. Power/Test, Active, LAN, and WLAN for each radio mode are easily

identified.

• Wi-FI Multimedia (WMM) support. WMM is a subset of the 802.11e standard. WMM

allows wireless traffic to have a range of priorities, depending on the kind of data.

Time-dependent information, like video or audio, has a higher priority than normal traffic.

For WMM to function correctly, wireless clients must also support WMM.

• Quality of Service (QoS) support. You can configure parameters that affect traffic

flowing from the wireless access point to the client station and traffic flowing from the

client station to the wireless access point. The QoS feature allows you to prioritize traffic,

such as voice and video traffic, so that packets do not get dropped.

• VLAN security profiles. Each security profile is automatically allocated a VLAN ID when

the security profile is modified.

802.11b/g/n Standards–Based Wireless Networking

The ProSafe Wireless-N Access Point WNAP320 provides a bridge between wired Ethernet

LANs and 802.11b/g- and 802.11n-compatible wireless LAN networks. It provides

connectivity between wired Ethernet networks and radio-equipped wireless notebook

systems, desktop systems, print servers, and other devices. Additionally, the wireless access

point supports the following wireless features:

• Aggregation support

• Reduced InterFrame spacing support

• Multiple input, multiple output (MIMO) support

• Distributed coordinated function (CSMA/CA, back-off procedure, ACK procedure,

retransmission of unacknowledged frames)

• RTS/CTS handshake

• Beacon generation

• Packet fragmentation and reassembly

• Auto or long preamble

• Roaming among wireless access points on the same subnet

Autosensing Ethernet Connections with Auto Uplink

The ProSafe Wireless-N Access Point WNAP320 can connect to a standard Ethernet

network. The LAN interface is autosensing and capable of full-duplex or half-duplex

operation.

The wireless access point incorporates Auto UplinkTM technology. The Ethernet port

automatically senses whether the Ethernet cable plugged into the port should have a

“normal” connection such as to a computer or an “uplink” connection such as to a switch or

hub. That port then configures itself correctly. This feature also eliminates any concerns

about crossover cables, as Auto Uplink accommodates either type of cable to make the right

connection.
