Wireless Settings
SSID Setup
Overview
This module enables you to set SSID-related parameters of the AP.
Broadcast SSID
When the AP broadcasts an SSID, nearby wireless clients can detect the SSID. When this
parameter is set to Disable, the AP does not broadcast the SSID and nearby wireless clients cannot
detect the SSID. In this case, you need to enter the SSID manually on your wireless client if you
want to connect to the wireless network corresponding to the SSID. This to some extent enhances
the security of the wireless network.
4UZK
After Broadcast SSID is set to Disable, a hacker can still connect to the corresponding wireless network if he/she
manages to obtain the SSID by other means. Therefore, disabling this function only ensures low network security.
Client Isolation
This parameter implements a function similar to the VLAN function for wired networks. It isolates the
wireless clients connected to the same wireless network corresponding to an SSID, so that the
wireless clients can access only the wired network connected to the AP. Applying this function to
hotspot setup at public places such as hotels and airports helps increase network security.
WMF
The number of wireless clients keeps increasing currently, but wired and wireless bandwidth
resources are limited. Therefore, the multicast technology, which enables single-point data
transmission and multi-point data reception, has been widely used in networks to effectively reduce
bandwidth requirements and prevent network congestion.
Nevertheless, if a large number of clients are connected to a wireless interface of a wireless network
and multicast data is intended for only one of the clients, the data is still sent to all the clients, which
unnecessarily increases wireless resource usage and may lead to wireless channel congestion. In
addition, multicast stream forwarding over an 802.11 network is not secure.
25
The WMF function of the AP converts multicast traffic into unicast traffic and forwards the traffic to
the multicast traffic destination in the wireless network. This helps save wireless resources, ensure
reliable transmission, and reduce delays.
Maximum Clients
This parameter specifies the maximum number of clients that can connect to the wireless network
corresponding to an SSID. If the number is reached, the wireless network rejects new connection
requests from clients. This limit helps balance load among the SSIDs of the AP.
Security Mode
A wireless network uses radio, which is open to the public, as its data transmission medium. If the
wireless network is not protected by necessary measures, any client can connect to the network to
use the resources of the network or access unprotected data over the network. To ensure
communication security, transmission links of wireless networks must be encrypted for protection.
The AP supports various security modes for network encryption, including None, WEP, WPA-PSK,
WPA2-PSK, Mixed WPA/WPA2-PSK, WPA, and WPA2.
None
It indicates that any wireless client can connect to the wireless network. This option is not
recommended because it affects network security.
WEP
Wired Equivalent Privacy (WEP) uses a static key to encrypt all exchanged data, and ensures that a
wireless LAN has the same level of security as a wired LAN. Data encrypted based on WEP can be
easily cracked. In addition, WEP supports a maximum wireless network throughput of only 54 Mbps.
Therefore, this security mode is not recommended.
WPA-PSK, WPA2-PSK, and Mixed WPA/WPA2-PSK
Mixed WPA/WPA2-PSK indicates that wireless clients can connect to a wireless network using
either WPA-PSK or WPA2-PSK.
In these security modes, an AP adopts a preshared key for authentication, and generates another
key for data encryption. This prevents the vulnerability caused by static WEP keys, and makes the
security modes suitable for ensuring security of home wireless networks. Nevertheless, because the
initial pre-shared key for authentication is manually set and all clients use the same key to connect
to the same AP, the key may be disclosed unexpectedly. This makes the security modes not suitable
for scenarios where high security is required.
WPA and WPA2
To address the key management weakness of WPA-PSK and WPA2-PSK, the WiFi Alliance puts
forward WPA and WPA2, which use 802.1x to authenticate clients and generate data encryption–
oriented root keys. WPA and WPA2 use the root keys to replace the preshared keys that set
manually, but adopt the same encryption process as WPA-PSK and WPA2-PSK.
WPA and WPA2 uses 802.1x to authenticate clients and the login information of a client is managed
by the client. This effectively reduce the probability of information leakage. In addition, each time a
client connects to the AP that adopts the WPA or WPA2 security mode, the RADIUS server
generates a data encryption key and assigns it to the client. This makes it difficult for attackers to
obtain the key. These features of WPA and WPA2 help significantly increase network security,
making WPA and WPA2 the preferred security modes of wireless networks that require high security.

Radio
Overview
The Radio module is used to set RF parameters of the AP. This section describes some functions of
the module.
Inter-SSID User Isolation
This function isolates the wireless clients connected to different wireless networks corresponding to
the same RF band. For example, if user 1 connects to the wireless network corresponding to SSID1
of RF band 1, whereas user 2 connects to the wireless network corresponding to SSID2 of RF band
1, the two users cannot communicate with each other after inter-SSID user isolation is implemented
for RF band 1.
Client Load Balancing
If an AP uses two or more identical RF bands, wireless clients may not be evenly connected to the
RF bands, resulting in traffic imbalance between the RF bands. Client load balancing appropriately
achieve balance between the RF bands to effectively optimize network resource usage.
When the number of users connected to an RF band of the AP reaches the threshold specified by
Client Load Balancing Threshold, client load balancing is performed.
The following figure provides an example. RF band 1 and 3 of the AP are 2.4 GHz bands. Client 1
connects to RF band 1, whereas clients 2 to 6 connect to RF band 2. If client load balancing is
enabled, the client load balancing threshold is 5, and the client load balancing offset is 4, when client
7 sends a connection request to RF band 2, client 7 is connected to RF band 1 because the
threshold and offset of RF band 2 has been reached.
48
Changing the RF Settings
1. Choose Wireless > Radio.
2. Select the RF band to be configured.
3. Change the parameters as required. Generally, you only need to change the Enable Wireless,
Channel, and TX Power settings.
4. Click Save.

Radio Optimizing
Overview
Wireless Network Application Scenario
Generally, wireless networks application scenarios include those with a common user density and
those with a high user density..
Application scenario with a common user density
In an office, public building, school, warehouse, or hospital, the wireless network must provide
coverage to many users in a large area.
Application scenario with a high AP density
In a large crowded area with many wireless clients, many APs are deployed to provide coverage
(AP/225~500 M2). The common application scenarios with a high AP density include:
− Conference hall, theatre, exhibition hall, and dining hall
− Indoor/outdoor stadium
− College classroom
− Airport and railway station
Performance Optimization Parameters
To cater to different requirements for wireless connection in different application scenarios and help
customers set up optimum wireless services, IP-COM provides a series of performance optimization
parameters.
5GHZ SSID priority
The 2.4 GHz band is more widely used for wireless coverage than the 5 GHz band. However, the
2.4 GHz band offers only 3 non-overlapping channels. Therefore, the channels are busy, resulting in
great wireless signal interference. Actually, the 5 GHz band can offer more non-overlapping
channels. In China, it offers 9 channels. In Some other countries, it offers more than 20 channels.
An increasing number of users are using wireless clients that work at the 2.4 GHz and 5 GHz bands
at the same time as wireless network development continues. However, a dual-band client often
connects to the 2.4 GHz network by default, increasing the imbalance between the 2.4 GHz network
and 5 GHz network.
The 5GHZ SSID priority feature makes a dual-band client to connect to the 5 GHz network first to
reduce the workload and interference at the 2.4 GHz band for better user experience.
52
4UZK
The 5GHZ SSID priority feature is applicable only after both the 2.4 GHz and 5 GHz bands of the AP are enabled and
assigned the same SSID, security mode, and password.
Airtime Scheduling
Traditional packet distribution is performed in FIFO mode. In an environment that involves various
wireless data rates, high-speed clients has high transmission capability and high frequency use
efficiency but has less time to access the air interface. On the contrary, low-speed clients has low
transmission capability and low frequency use efficiency but has more time to access the air
interface. This reduces the overall throughput of each AP, resulting in lower system efficiency.
Air interface scheduling assigns the same length of time for high-speed clients and low-speed
clients to access the air interface, enabling the high-speed clients to transmit more data. This
increases the overall throughput and number of connected users of an AP.
53
Signal Transmission
In a scenario with a common AP density, an AP must cover a large area. Therefore, the major WLAN
constraint is transmission loss. In a scenario with a high AP density, many users and clients gather
in a large area. Many APs must be deployed and they are within the visual distance of most users. In
this scenario, the major WLAN constraint is inter-AP interference.
The signal transmission capability can be adjusted together with the transmit power based on
scenarios to effectively ease the WLAN constraints. Select Coverage-oriented for a scenario with a
common AP density, and select Capacity-oriented for a scenario with a high AP density.
Signal Reception
In a scenario with a common AP density, a small number of APs are deployed and successful AP
connection by clients must be ensured. In a scenario with a high AP density, a large number of APs
are deployed and connection by clients to AP with stronger signals must be ensured.

Parameter
Description
Beacon Interval
It specifies the interval for transmitting the Beacon frame. The value range is 20 to 999. The unit
is millisecond.
The Beacon frame is transmitted at the specified interval to announce the presence of a wireless
network. Generally
, a smaller interval enables wireless clients to connect to the AP more
quickly, while a larger interval ensures
higher data transmission efficiency.
Fragment
Threshold
It specifies the threshold of a
fragment. The value range is 256 to 2346. The unit is byte.
Fragmenting is a process that divides a frame into several fragments, which are transmitted and
acknowledg
ed separately. If
the size of a frame exceeds this threshold, the frame is fragmented.
In case of a high error rate, you can reduce the threshold to enable the AP to resend only the
fragments that have not been sent successfully, so as to increase the fram
e throughput.
In an environment without interference, you can increase the threshold to reduce the number of
acknowledgement times, so as to increase the frame throughput.
RTS Threshold
It specifies the frame length threshold for triggering the RTS/CTS me
chanism.
If a frame exceeds this threshold, the RTS/CTS mechanism is triggered to reduce
conflicts.
The
value range is 1 to 2347. The unit is byte.
Set the RTS threshold based on the actual situation. An excessively small value increases the
RTS frame tran
smission frequency and bandwidth requirement. A higher RTS frame
transmission frequency enables a wireless network to recover from conflicts
quicker. For a
wireless network with high user density, you can reduce this threshold for reducing conflicts.
The RTS mechanism requires some network bandwidth. Therefore, it is triggered only when
frames exceed this threshold.
DTIM Interval
It specifies the interval for transmitting the Delivery Traffic Indication Message (DTIM) frame.
The value range is 1 to 255. T
he unit is Beacon.
A countdown starts from this value. The AP transmits broadcast and multicast frames in its
cache only when the countdown reaches zero.
For example, if DTIM Interval is set to 1, the AP transmits all cached frames at the Beacon

nario.
− Coverage-oriented
: This mode enables more wireless devices to connect to the AP in
an area with low AP density.
− Capacity-oriented
: This mode ensures that each wireless device in an area with high
AP density connects to the AP with the strongest signal.
− Default
: This mode enables the AP to achieve a balance between the other two modes.
4UZK
This feature is available only to the 2.4 GHz band.
Airtime
Scheduling

WMM Setup
Overview
802.11 networks offer wireless access services based on the Carrier Sense Multiple Access with
Collision Avoidance (CSMA/CA) channel competition mechanism, which allows all wireless clients to
fairly compete for channels. All the services implemented over wireless networks share the same
channel competition parameters. Nevertheless, different services usually have different
requirements for bandwidth, delay, and jitter. This requires wireless networks to offer accessibility
based on the services implemented over the networks.
WMM is a wireless QoS protocol used to ensure that packets with high priorities are transmitted first.
This ensures better voice and video service experience over wireless networks.
WMM involves the following terms:
Enhanced Distributed Channel Access (EDCA): It is a channel competition mechanism to ensure
that packets with higher priorities are assigned more bandwidth and transmitted earlier.
Access Category (AC): AC: The WMM mechanism divides WLAN traffic by priority in descending
order into the AC-VO (voice stream), AC-VI (video stream), AC-BE (best effort), and AC-BK
(background) access categories. The access categories use queues with different priorities to
send packets. The WMM mechanism ensures that packets in queues with higher priorities have
more opportunities to access channels.
According to the 802.11 protocol family, all devices listen on a channel before using the channel to
send data. If the channel stays idle for or longer than a specified period, the devices wait a random
backoff period within the contention window. The device whose backoff period expires first can use
the channel. The 802.11 protocol family applies the same backoff period and contention window to
all devices across a network to ensure that the devices have the same channel contention
opportunity.
59
EDCA Parameters
WMM changes the contention mechanism of 802.11 networks by dividing packets into four ACs,
among which the ACs with higher priorities have more opportunities to access channels. The ACs
help achieve different service levels.
WMM assigns each AC a set of EDCA parameters for channel contention, including:
Arbitration Inter Frame Spacing Number (AIFSN): Different from the fixed distributed inter-frame
spacing (DIFS) specified in the 802.11 protocol family, AIFSN varies across ACs. A greater
AIFSN indicates a longer backoff period. See AIFS in the following figure.
Contention window minimum (CWmin) and contention window maximum (CWmax) specify the
average backoff period. The period increases along with these two values. See the backoff slots
in the following figure.
Transmission Opportunity (TXOP): It specifies the maximum channel use duration after
successful channel contention. The duration increases along with this value. The value 0
indicates that a device can send only one packet through a channel after winning contention for
the channel.
ACK Policies
WMM specifies the Normal ACK and No ACK policies.
According to the No ACK policy, no ACK packet is used during wireless packet transmission to
acknowledge packet reception. This policy is applicable to scenarios where interference is mild
and can effectively improve transmission efficiency. In case of strong interference, lost packets
are not sent again if this policy is adopted. This leads a higher packet loss rate and reduces the
overall performance.
According to the Normal ACK policy, each time a receiver receives a packet, it sends back an
ACK packet to acknowledge packet reception.
Changing the WMM Settings
By default, the WMM function is disabled. To enable the function, perform the following procedure:
60
1. Choose Wireless > WMM Setup.
2. Select the RF band for which WMM is to be configured.

SNMP
Overview
The Simple Network Management Protocol (SNMP) is the most widely used network management
protocol in TCP/IP networks. SNMP enables you to remotely manage all your network devices
compliant with this protocol, such as monitoring the network status, changing network device
settings, and receive network event alarms.
SNMP allows automatic management of devices from various vendors regardless of physical
differences among the devices.
SNMP Management Framework
The SNMP management framework consists of SNMP manager, SNMP agent, and Management
Information Base (MIB).
SNMP manager: It is a system that controls and monitors network nodes using the SNMP
protocol. The SNMP manager most widely used in network environments is Network
Management System (NMS). An NMS can be a dedicated network management server, or an
application that implements management functions in a network device.
SNMP agent: It is a software module in a managed device. The module is used to manage data
about the device and report the management data to an SNMP manager.
MIB: It is a collection of managed objects. It defines a series of attributes of managed objects,
including names, access permissions, and data types of objects. Each SNMP agent has its MIB.
An SNMP manager can read and/or write objects in the MIB based on the permissions assigned
to the SNMP manager.
An SNMP manager manages SNMP agents in an SNMP network. The SNMP manager exchanges
management information with the SNMP agents using the SNMP protocol.
Basic SNMP Operations
The AP allows the following basic SNMP operations:
Get: An SNMP manager performs this operation to query the SNMP agent of the AP for values of
one or more objects.
Set: An SNMP manager performs this operation to set values of one or more objects in the MIB
of the SNMP agent of the AP .
78
SNMP Protocol Version
The AP is compatible with SNMP V1 and SNMP V2C and adopts the community authentication
mechanism. Community name is used to define the relationship between an SNMP agent and an
SNMP manager. If the community name contained in an SNMP packet is rejected by a device, the
packet is discarded. A community name functions as a password to control SNMP agent access
attempts of SNMP managers.
SNMP V2C is compatible with SNMP V1 and provides more functions than SNMP V1. Compared
with SNMP V1, SNMP V2C supports more operations (GetBulk and InformRequest) and data types
(such as Counter64), and provides more error codes for better distinguishing errors.
MIB Introduction
An MIB adopts a tree structure. The nodes of the tree indicate managed objects. A path consisting of
digits and starting from the root can be used to uniquely identify a node. This path is call an object
identifier (OID). The following figure shows the structure of an MIB. In the figure, the OID of A is
1.3.6.1.2.1.1, whereas the OID of B is 1.3.6.1.2.1.2.

Uplink Detection
Overview
In AP mode, the AP connects to its upstream network using the LAN0 port. If a critical node between
the LAN0 port and the upstream network fails, the AP as well as the wireless clients connected to
the AP cannot access the upstream network. If uplink detection is enabled, the AP regularly pings
specified hosts through the LAN0 port. If all the hosts are not reachable, the AP stops its wireless
service and wireless clients cannot find the SSIDs of the AP. The client can reconnect to the AP only
after the connection between the AP and the upstream networks is recovered.
If the uplink of the AP with uplink detection enabled is faulty, wireless clients can connect to the
upstream network through another nearby AP that works properly.
