EAP280-L Indoor Wireless AP
EAP280-L
EAP280-L
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 0°C to +50°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.
Product Overview
EAP-280-L is new-generation 802.11n-based high-performance
gigabit 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.
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 EAP280-L may be used with DCN wireless ACs to
perform data forwarding, security, and access control of wireless
users.
The EAP280-L operates in a 2.4 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 .
Featuring flexible installation, the EAP280-L may be installed on
the wall, desk top, or ceiling. The EAP280-L supports power over
Ethernet (PoE). The EAP280-L is a series of high-rate wireless
APs preferred in various application environments for purposes
such as campus WLAN access, campus coverage, and ISP' hot
spot coverage.
Highlights
High-Performance and High-Reliability Wireless
Network
► High-speed wireless broadband access
The EAP280-L supports the 802.11bgn standard and provides
an access bandwidth up to 300 Mbps.
► High-Performance RF characteristics
Professional optimized design is employed for the RF module
of the EAP280-L, so that a single antenna port supports 24
dBm 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
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.
► 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 lowrate
terminal access environment, however, cannot be resolved by
simply employing rate control and traffic shaping. DCN smart 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 finish 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.
EAP280-L
► 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
diversified intelligent load balancing means:
--AP load balancing based on traffic
--AP load balancing based on the number of users
--AP load balancing based on frequency bands
--Access control based on signal strength of terminals
--Mandatory roaming control of terminals to direct terminals to
APs with stronger signals
► Intelligent identification 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 finer granularity.
► Comprehensive support for IPV4/V6 dual-stack
network
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 fine granularity
Each AP supports a maximum of 16 WLANs to implement
multilayer 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 significant in a multiWLAN
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
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 certificate authentication
EAP280-L
► 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 realtime
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,
authentication servers, and other network devices without
changing existing network architecture.
When used with a DCN wireless AC, DCN smart APs support
plug-and-play and zero configuration. The wireless AC undertakes
all the management, control, and configuration of the APs.
Network administrators do not need to separately manage or
maintain a huge number of wireless APs. All actions, such as
configuration, firmware 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 fit 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 nonconvergence mirroring of a working channel and
sampling of all channels in polling mode as well to flexibly meet
various wireless network monitoring, operation, and maintenance
requirements.
