H3C WA6638 New Generation 802.11ax Indoor Series Access Points
- H3C WA6638 Internal Antennas 12 Streams Triple Radio 802.11ax/ac/n AP
H3C WA6638 series access points are the latest generation wireless access points developed based on 802.11ax standard. They are designed with creative triple-radio 802.11ax technology standard, and provide a transmission speed at least 2 times faster than 802.11ac products. This makes the series suitable for high-density access scenarios, such as hotel, stadium, and enterprise campus, and e-schoolbag applications.
With built-in antennas, WA6638 support triple radio and can support multi-rate uplink ports with the max speed of 5Gbps or 10Gbps. WA6638 is compact in appearance and support both wall mounting and ceiling mounting.
New-generation Wi-Fi standard 802.11ax (Wi-Fi 6)
802.11ac, the fifth-generation wireless technology, provides a transmit rate of up to 1733Mbps per radio. 802.11ax, the sixth-generation wireless technology, provides a maximum of eight spatial streams per 5GHz radio and up to 4.8Gbps in transmission speed. For example, the WA6638 triple radio AP can provide up to 5.95Gbps access rate (2.4Gbps on 5GHz-1 and 5GHz-2 plus 1.15Gbps on 2.4GHz), which is suitable for all high-density access scenarios and provides better access experience.
H3C WA6638 series AP supports DL/UL MU-MIMO technology, which is the most important feature of 802.11ax. DL/UL MU-MIMO technology allows AP to send data to multiple stations simultaneously. For example, WA6638 can communicate with up to four stations at the same time, breaking through the traditional wireless serial communication mechanism, increasing the utilization rate of wireless spectrum resources, improving the number of effective access users and access experience under high-density deployment.
Smart cloud access and optimal WLAN TCO
The WA6638 series complies with the 802.11ax standard. It works on triple radio and provides high-speed transmission that is at least 2 times faster than 802.11ac products under the same conditions. The WA6638 series is available for easy maintenance and management from the H3C Cloudnet platform. Through smart RF optimization technologies, the series provides mobile cloud access in coverage scope, access density, and operation stability, and achieves the optimal wireless network Total Cost of Ownership (TCO).
High-efficiency uplink ports with support of multiple rates
The uplink ports on the WA6638 support auto-negotiation of various transmit rates, including 100Mbps, 1000Mbps, 2.5Gbps, and 5Gbps. WA6638 supports 10Gbps multi-rate uplink.
Orthogonal frequency division multiple access (OFDMA)
802.11ax uses OFDMA to allow multiple users to transmit data simultaneously. OFDMA splits a channel into sub-channels, known as resource units (RUs), with specific subcarriers, and assigns RUs to different users for simultaneous transmission. OFDMA enables simultaneous multi-user transmission and reduces latency caused by channel contention.
802.11ax assigns a different color per BSS to help WA6638 identify co-channel interference and stop transmission in time. If a radio detects 802.11ax signals from a BSS that has the same color as the radio's BSS, it determines that co-channel interference exists and stops data transmission. This optimizes frequency reuse and improves network capacity.
Target Wake Time (TWT)
TWT improves power efficiency and reduces contention by increasing client sleep time and allowing negotiation of the times that clients can access the medium.
H3C WA6638 series adopts built-in Bluetooth module which can support 10m long-distance Console function, avoid additional workload in the process of equipment installation and maintenance, reduce the difficulty of troubleshooting, and support iBeacon shaking.
Support for IoT services
For the various application in IoT era, WA6638 has been designed IoT port for H3C T300 IoT modules to provide short-distance and low-power consumption IoT services, such as BLE, RFID, ZigBee, and UWB. Those APs can connect up to ten T300 modules by IoT port. Both this IoT port and network port support link aggregation (LACP) which increase availability and capacity.
WA6638 employs a green design that supports dynamic MIMO power saving (DMPS), enhanced automatic power save delivery (E-APSD), and smart identification of terminal network requirements. It can dynamically adjust the MIMO working mode and efficiently put terminals to sleep.
WA6638 supports green AP mode that enables single radio standby and allows for more precise power control.
WA6638 supports the innovative per-packet power control (PPC) technology, which reduces standby power consumption and improves mobile device standby time.
WA6638 supports both centralized forwarding and local forwarding. With centralized forwarding, APs tunnel incoming data frames to the AC and the AC forwards the data frames. With local forwarding, APs directly forward data frames. The local forwarding mode significantly saves wired bandwidth.
IPv4 and IPv6 dual stack (Native IPv6)
WA6638 is fully compliant with IPv6, and implements dual IPv4/IPv6 protocol stacks. It can automatically associate with an AC to provide wireless services no matter in an IPv4 or IPv6 network, so that it never runs as an information silo.
As one of components of H3C iMC, EAD integrates network access and endpoint security products, and helps ensure that only wireless clients that comply with enterprise security policies can access the network. When working with a security policy server, it can remind users, isolate or log them off when their systems are infected or not patched correctly. Only wireless clients that are complied with security policies are admitted. This enhances overall wireless security.
Remote probing and analysis
WA6638 can act as a remote probing and analysis sensor to monitor a WLAN, collect channel information, and report the information to the local device for further analysis. This can satisfy wireless network monitoring and maintenance requirements.
ROE, through feature- and protocol-based RF optimization, provides greater speed and QoS in middle- to high-density access and streaming media transmission scenarios. It provides features such as multi-user fairness, mixed access fairness, interference filtering, speed optimization, band navigation, multicast optimization (IPv4/IPv6), per-packet power control, and intelligent bandwidth guarantee.
Real Time Spectrum Guard (RTSG)
Real Time Spectrum Guard (RTSG) is the innovative H3C professional state-monitoring program for the wireless spectrum. H3C 802.11ax series AP supports the internal RF data acquisition module to achieve deeply integrated monitoring and real time spectrum protection.
The RTSG Console is integrated into the iMC (intelligent Management Center), and performs data acquisition through the CAPWAP tunnel management and Sensor AP. It can achieve 24x7 wireless signal quality monitoring, trend assessment and unauthorized interference alert. Through active probe and 2.4GHz/5GHz RF interference source (WiFi or non-WiFi) in every band, it provides a graphic representation of real-time FFT plot of the spectral density plot, spectrum diagram, the duty cycle map, event spectrum diagram, channel gain and interference gain. It can also automatically identify the source of interference, to determine the location of rogue wireless equipment, to ensure the wireless network is always in great shape. Combined with H3C iMC IAR (Intelligent Analysis Report) module, it can maintain a complete history of RF quality in the coverage area, including its trace and playback, automatically generate customized trend, compliance and audit reports.
To cater for the different supervision demands in user's wireless environment, the RTSG solution can be deployed in either Local mode or Monitor mode. In Local Mode, you can maintain normal user access and data packet forwarding without compromising effective spectrum protection.
H3C Cellular Coexistence Feature (CCF)
H3C uses built-in hardware filtering to minimize the impact of interference from 3G/4G cellular networks.
Anchor AC mode
Anchor AC mode is designed for networks of all sizes, including SMB. In Anchor AC mode, AP will serve as a virtual controller for the entire network.
H3C cloud-managed APs were developed based on the Cloudnet platform, on which network administrators can manage the cloud-managed APs directly, for example, view cloud-managed AP status in real time and deploy configurations from the cloud to cloud-managed APs. This greatly improves network efficiency and enhances security and stability.
WA6638 supports session- and traffic-based load balancing. When the load of the AP reaches the upper limit, the AC rejects the association requests of new clients and directs the clients to another AP with smaller load. What sets H3C intelligent load balancing apart from existing load balancing solutions is that it starts load balancing only for clients that are in the overlapping AP coverage. This maximizes wireless network capacity.
Intelligent unified wired and wireless management
The whole series of H3C wireless products can be managed by the Wireless Service Manager (WSM) component of H3C Intelligent Management Center (IMC). WSM provides unified management of wired and wireless networks, adding wireless network management functions into existing wired network management systems.
WSM offers a simple and user friendly management platform for wireless network administrators. It implements panel management, troubleshooting, performance monitoring, software version control, configuration management, and user access management of wireless devices. In addition, it can manage wired devices by cooperating with other components in IMC.
