DCWL-7962OT Outdoor Wireless AP

DCWL-7962OTProduct OverviewThe 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-7962OTHighlightsHigh-Performance and High-Reliability Wireless Network► High-speed wireless broadband accessThe 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 connectionsGE 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 characteristicsProfessional 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 APsIn 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 rangeThanks 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 mechanismDCN 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 mechanismSince 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 managementDCN 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 fairWhen 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 trafc shaping. DCN smart

DCWL-7962OTAPs 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 mechanismIn 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 diversied intelligent load balancing means:AP load balancing based on trafcAP load balancing based on the number of usersAP load balancing based on frequency bandsAccess control based on signal strength of terminalsCall admission control (CAC) based on the number of users to well guarantee the access performance and bandwidths of terminals with high-priority applicationsMandatory roaming control of terminals to direct terminals to APs with stronger signals► Intelligent identication of terminalsDCN 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 networksPowered 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 roamingDCN 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 policyDCN 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 defenseDCN 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 granularityEach 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 signicant in a multi-WLAN environment.► Secure user admissionDCN 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 authenticationCaptive portal authentication, including built-in portal, external portal, and custom portal authentication modesMAC address authenticationLDAP authenticationWAPI encryption and authenticationWired/wireless integrated authentication and accounting► Wireless SAVIDCN 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 authenticationWith 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-7962OTterminal 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 mechanismAn 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 authenticationAP password authenticationBidirectional digital certicate authentication► Real-time spectrum protectionDCN 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-playDCN 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, Item DCWL-7962OTDimensions (mm) 220 x 220 x 9510/100 /1000Base-T port 1PoE 802.3atMaximum power consumption 23.4 WRF port Four N-type female portsWorking frequency band 802.11a/n: 5.725 GHz to 5.850 GHz (China)802.11b/g/n: 2.4 GHz to 2.483 GHz (China)Modulation technologyOFDM: BPSK@6/9Mbps, QPSK@12/18Mbps, 16-QAM@24Mbps, 64-QAM@48/54MbpsDSSS: DBPSK@1Mbps, DQPSK@2Mbps, CCK@5.5/11Mbps MIMO-OFDM: MCS 0-15Transmit power Maximum 27 dBm for all rate levels and modulation modesPower adjustment granularity 1 dBmAP access speed802.11n: 20 MHz BW: 6, 5, 7.2, 13, 14.4, 19.5, 21.7, 26, 28.9, 39, 43.3, 52, 57.8, 58.5, 65, 72.2, 78, 86.7, 104, 115.6, 117, 130, 144 Mbps40 MHz BW: 13.5, 15, 27, 30, 40.5, 45, 54, 60, 81, 91, 108, 120, 121.5, 135, 140, 150, 162, 180, 216, 240, 243, 270, 300 Mbps802.11g: 54, 48, 36, 24, 18, 12, 11, 9, 6, 5.5, 2, 1 Mbps802.11b: 11, 5.5, 2, 1 Mbps802.11a: 54, 48, 36, 24,18, 12, 9, 6 MbpsHardware Specificationsauthentication 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 conguration. 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 conguration, rmware upgrade, and security policy updating, are performed uniformly under the control of the wireless AC.► Fit and Fat modesDCN 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 upgradeDCN 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 analysisDCN 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.Product Specications
