DCWL-7962OT Outdoor Wireless AP
DCWL-7962OT
Product Overview
The DCWL-7962OT is a series of new-generation 802.11n-based
high-performance gigabit outdoor wireless access points (APs)
launched by Digital China Networks Co., Ltd. (hereinafter referred
to as DCN) for industrial users. It provides a wireless access rate
equivalent to at least six times the rate available on a conventional
802.11a/b/g network, and offers wider coverage. The DCWL-
7962OT uses GE ports as its uplink ports for access, which break
through the limitations of FE ports and enable wireless multimedia
applications to come true.
While completely taking into consideration important factors,
such as wireless network security, radio frequency (RF) control,
mobile access, quality of service (QoS) guarantee, and seamless
roaming, the DCWL-7962OT may be used with DCN wireless
ACs to perform data forwarding, security, and access control of
wireless users.
The DCWL-7962OT operates in a 2.4 GHz or 5 GHz band and
employs technologies such as multiple-input multiple-output
(MIMO) and orthogonal frequency division multiplexing (OFDM),
providing a data transmission rate of at most 300 Mbps per
channel and 600 Mbps per dual channels.
The DCWL-7962OT employs industrial standard components. Its
shell of the IP66 class is solid, waterproof, and dustproof, enabling
the device to suit an adverse indoor environment. Along with a
high-gain outdoor antenna of DCN, the DCWL-7962OT provides
customers with a choice for constructing a high-performance and
high-coverage wireless network. The DCWL-7962OT is a series
of high-rate wireless APs preferred in various outdoor application
environments for purposes such as campus WLAN access,
campus coverage, and operators' hot spot coverage.
DCWL-7962OT
Highlights
High-Performance and High-Reliability Wireless
Network
► High-speed wireless broadband access
The DCWL-7962OT supports the 802.11abgn standard and
may operate in a 2.4 GHz or 5 GHz band. It provides an access
bandwidth up to 600 Mbps.
► GE ports for wired connections
GE ports are used as uplink ports for access, which break through
the limitations of conventional FE ports, so that wired ports are no
longer a bottleneck of wireless access rates, offering a platform for
smooth upgrade to support higher rates and more RF portfolios in
the future.
► High-performance RF characteristics
Professional optimized design is employed for the RF module
of the DCWL-7962OT, so that a single antenna port supports
27 dB transit power at all rate levels, thereby improving wireless
coverage in high-rate access scenarios.
► Automatic emergency mechanism of APs
In a centralized network architecture where t APs and a wireless
AC are deployed, the APs will be unable to operate normally when
the wireless AC is down and then the entire wireless network
will crash. DCN wireless APs support an automatic emergency
mechanism. This mechanism enables an AP to intelligently detect
links. When detecting that the wireless AC is down, the AP quickly
switches its operating mode so that it may continue to forward
data while enabling new users to access the network. This
mechanism attains high availability in the entire wireless network
and really helps wireless users to be always online.
► Broad operating temperature range
Thanks to deliberate hardware design and the selection of
dedicated components operating in a broad temperature
range, DCN smart APs may operate in an environment with its
temperature ranging from -40°C to 60°C.
► Dual-OS backup mechanism
DCN smart APs support a dual-OS backup mechanism. When an
AP fails to start from the active OS, it can immediately start from a
standby OS, thereby improving the long-term running reliability of
equipment in an adverse environment.
Wireless Network of Intelligent Control and Automatic
Perception
► Only 11n access control mechanism
Since 802.11n is downward compatible with the 802.11a/b/g
protocol, generally 802.11a/b/g users can also access an 802.11n
wireless access device. When this compatibility is provided,
however, users with 802.11n access capability will experience
performance degradation to a certain extent. On DCN smart APs,
a certain RF channel may be set to only 11n access mode so that
802.11n users have guaranteed bandwidths. For some 802.11n
wireless access devices capable of simultaneously providing dual
frequencies for user access, it is recommended that the 5 GHz
RF channel be set to only 11n access mode to guarantee a high-
speed bandwidth and access performance of 802.11n access
users; while the 2.4 GHz RF channel be set to compatible access
mode to guarantee normal access of original 802.11b/g users.
► Intelligent RF management
DCN smart APs may be used with a wireless AC to perform
automatic power and channel adjustment. They employ particular
RF detection and management algorithms to attain a better
RF coverage effect. When the signals of an AP are interfered
by strong external signals, the AP may automatically switch
to an appropriate operating channel under the control of the
AC to avoid such interference, thereby guaranteeing wireless
network communications. The system also supports wireless
network blackhole compensation. When an AP on the network
accidentally stops operating, the RF management function of the
AC compensates the resulting blind area of signals so that the
wireless network can still operate normally.
► Intelligent control of terminals based on airtime
fair
When some outdated 802.11b and 802.11g terminals are used
on a wireless network or some terminals are far way from APs,
negotiation rates will be low, causing a large number of users
to experience a long WLAN access delay, low rates, or poor
overall AP performance. The AP performance problem in a low-
rate terminal access environment, however, cannot be resolved
by simply employing rate control and trafc shaping. DCN smart
DCWL-7962OT
APs have essentially resolved this problem by using intelligent
control of terminals based on airtime fairness, ensuring that a user
can always enjoy the same joyful WLAN experience in the same
location, no matter what type of the terminal the user is holding.
The intelligent control of terminals based on airtime fairness
greatly improves the performance of both the client and the entire
network. It enables all clients with high data transmission rates
to attain strikingly higher performance while low-rate clients are
almost not affected at all. The performance will be even more
obviously higher on an open wireless network. Once high-rate
clients nish data transmission, fewer clients will be transmitting
data on the wireless network. In this case, there will be less
contention and retry on the network, thereby greatly improving
overall AP performance.
► Intelligent load balancing mechanism
In general, a wireless client will select an AP according to the
signal strength of APs. When this uncontrolled access mode is
applied, however, a large number of clients could be connected
to the same AP simply because the AP provides strong signals.
As more clients are connected to an AP, the bandwidth available
to each client will be smaller, thereby greatly affecting user
experience of the clients. DCN wireless products support
diversied intelligent load balancing means:
AP load balancing based on trafc
AP load balancing based on the number of users
AP load balancing based on frequency bands
Access control based on signal strength of terminals
Call admission control (CAC) based on the number of users
to well guarantee the access performance and bandwidths of
terminals with high-priority applications
Mandatory roaming control of terminals to direct terminals to APs
with stronger signals
► Intelligent identication of terminals
DCN smart APs may be used with DCN wireless ACs and a
unified authentication platform to intelligently identify the size,
system type, and type of each terminal; and comprehensively
support mainstream smart terminal operating systems, such as
Apple iOS, Android, and Windows. They intelligently identify the
size of a terminal and adaptively present a portal authentication
page of the corresponding size and page pattern, freeing users
from multiple times of dragging to adjust the screen and enabling
users to enjoy more intelligent wireless experience. They can also
intelligently identify the system type of each terminal and present
the system type of each terminal such as Windows, MAC OS, or
Android on the unified authentication platform, exhibiting every
detail of intelligence to users. In addition, they can intelligently
identify the type of each terminal such as the mobile phone,
tablet, or PC, and implement dynamic policy control of terminals
according to different types of the terminals, making possible
more intelligent user control at a ner granularity.
► Comprehensive support for IPv4/v6 dual-stack
networks
Powered by DCN cutting-edge IPv6 technology, DCN smart
APs may be deployed on an IPv6 network, with IPv6 tunnels
established through auto negotiation between a wireless AC and
an AP. When the wireless AC and the AP completely operate
in IPv6 mode, the wireless AC can still correctly identify IPv4
terminals and process IPv4 packets from wireless clients.
Featuring flexible adaptability to IPv4/6, DCN smart APs cater
to complex applications involved in migration from an IPv4
network to an IPv6 network. They not only provide IPv4 service to
customers on an IPv6 network, but also enable users on an IPv4
network to log in to the network through the IPv6 protocol at ease.
► Network-wide seamless roaming
DCN wireless ACs support an advanced wireless AC cluster
technology, which enables multiple ACs to synchronize online
connection information and roaming records of all users to each
other in real time. This technology implements not only L2/L3
seamless roaming inside a wireless AC but also fast roaming
across wireless ACs. As client IP address information does not
change and re-authentication is not required in the roaming
process, the continuity of real-time mobile services is well
guaranteed.
Secure and Controllable Wireless Network
► User isolation policy
DCN wireless APs support the isolation of wireless users from
one another. If this user isolation function is enabled, two wireless
clients cannot directly communicate with each other but can only
access an upstream wired network. This further guarantees the
security of wireless network applications.
► Wireless intrusion detection and intrusion defense
DCN wireless APs support wireless intrusion detection and
intrusion defense features, such as detection of unauthorized
wireless devices, intrusion detection, blacklist, and white list,
thereby greatly improving security management of an entire
wireless network.
► Wireless user management at a ne granularity
Each AP supports a maximum of 32 WLANs to implement multi-
layer multi-service management of wireless users at a fine
granularity. Each WLAN supports access control and uplink/
downlink rate limit based on MAC or IP addresses. These
WLANs may be bound to virtual local area networks (VLANs).
In addition, different authentication and accounting policies can
be implemented. This feature is practically signicant in a multi-
WLAN environment.
► Secure user admission
DCN smart APs may be used with wireless ACs to provide multiple
secure access, authentication, and accounting mechanisms for
various application environments. These mechanisms include:
802.1x authentication
Captive portal authentication, including built-in portal, external
portal, and custom portal authentication modes
MAC address authentication
LDAP authentication
WAPI encryption and authentication
Wired/wireless integrated authentication and accounting
► Wireless SAVI
DCN wireless network products support a source address
validation (SAVI) technology to deal with spoofed packet attacks
that keep emerging on today's campus networks. As users' IP
addresses are obtained through an address allocation protocol,
users access the Internet using correct addresses in subsequent
applications and cannot spoof others' IP addresses, thereby
guaranteeing the reliability of source addresses. In addition, the
SAVI technology is combined with a portal technology to further
guarantee the authenticity and security of packets of all users
accessing the Internet.
► PEAP user authentication
With the popularization and application of smart terminals,
wireless terminal users require authentication mechanisms
of higher usability and convenience. Using a mechanism that
combines portal authentication and MAC address authentication,
DCN wireless network products support Protected Extensible
Authentication Protocol (PEAP) authentication to attain better
user experience. Initially a user needs to manually perform portal
authentication and later the user gets authenticated through PEAP
in automatic mode. DCN wireless network products feature high
DCWL-7962OT
terminal adaptation and provide good authentication compatibility.
They adapt to the majority of WLAN terminals and do not need to
adapt to clients. DCN wireless network products are compatible
with existing portal authentication modes.
► Secure access mechanism
An AP is usually deployed in a public area and therefore requires
a strict security mechanism to guarantee the legality of access
devices. The following secure access mechanisms may be
applied between a DCN smart AP and a wireless AC:
AP MAC address authentication
AP password authentication
Bidirectional digital certicate authentication
► Real-time spectrum protection
DCN smart APs support a built-in RF collection module that
integrates RF monitoring and real-time spectrum protection.
By implementing communications and data collection through
the respective AP, the RF collection module performs wireless
environment quality monitoring, wireless network capability
tendency evaluation, and unexpected-interference alarms. It
resorts to a graphical means to actively detect and identify RF
interference sources (Wi-Fi or non-Wi-Fi) and provides a real-
time spectrum analysis diagram. In addition, it can automatically
identify interference sources and determine the locations of
problematic wireless devices, ensuring that a wireless network
attains optimal performance.
Easy-to-Manage Wireless Network
► Plug-and-play
DCN smart APs are able to automatically discover DCN wireless
ACs. A wireless network function can be enabled on an AP
without performing any configuration on the AP at all. The AP
can be seamlessly integrated with existing switches, firewalls,

conguration, rmware upgrade, and security policy updating, are
performed uniformly under the control of the wireless AC.
► Fit and Fat modes
DCN smart APs may work in fit or fat mode and can flexibly
switch between the fit mode and the fat mode according to
network planning requirements. Users may also flexibly choose
an ex-factory device version according to specific application
requirements. APs working in t mode are managed by a wireless
AC in a centralized manner. System administrators may easily
manage the entire network as the states of all the APs are clear at
a glance.
► Automatic AP version upgrade
DCN smart APs may be automatically associated with a wireless
AC on the live network to automatically download a latest software
version and get automatically upgraded, thereby reducing the
workload during network maintenance.
► Remote probe analysis
DCN smart APs support a remote probe analysis function, which
listens to and captures Wi-Fi packets in the coverage and mirrors
them to a local analysis device in real time to help network
administrators better perform troubleshooting or optimization
analysis. The remote probe analysis function can perform non-
convergence mirroring of a working channel and sampling of all
channels in polling mode as well to exibly meet various wireless
network monitoring, operation, and maintenance requirements.
