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.

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 fit 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.

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 traffic shaping. DCN smart
