Huawei AP4050DE-M Access Point DatasheetProduct OverviewHuawei AP4050DE-M is an 802.11ac Wave 2 access point (AP) that supports 2x2 MIMO and two spatial streams. It provides comprehensive service support capabilities and features high reliability, high security, simple network deployment, automatic AC discovery and configuration, and real-time management and maintenance, which meets network deployment requirements. The AP has built-in smart antennas and supports smooth evolution from 802.11n to 802.11ac and can provide gigabit access for wireless users. The AP4050DE-M is applicable to commercial chains, medical, warehousing, manufacturing, and logistics environments.AP4050DE-M●802.11ac Wave 2 standards compliance, MU-MIMO (2SU-2MU), delivering services simultaneously on 2.4G and 5G radios, at a rate of up to 400 Mbit/s at 2.4 GHz, 867 Mbit/s Mbit/s at 5 GHz, and 1.267 Gbit/s for the device.●Smart antenna array technology enables targeted signal coverage for mobile terminals, reduces interferences, and improves signal quality. Additionally, it implements millisecond-level switchover as STAs move.●Built-in Bluetooth 5.0, increasing the working distance and working with eSight to accurately locate Bluetooth terminals.●Supports the Fat, Fit, and cloud modes and enables Huawei cloud-based management platform to manage and operate APs and services on the APs, reducing network O&M costsFeature DescriptionsSmart antenna array technology●The AP integrates smart antenna and implicit beamforming technologies to implement more precise user detection, suppress interference, and improve signal quality, enabling users to have a seamless, smooth wireless network experience.MU-MIMO●The AP supports MU-MIMO to send data to multiple STAs at the same time (currently, most 802.11n or 802.11ac Wave 1 APs can only send data to one STA simultaneously).GE access●The APs support the 80-MHz bandwidth mode. Frequency bandwidth increase brings extended channels and more sub-carriers for data transmission, and a 2.16-fold rate increase. Support for High Quadrature Amplitude Modulation (HQAM) at 256-QAM increases the 5 GHz radio rate to 867 Mbit/s and the AP rate to 1.267 Gbit/s.Cloud-based management●Huawei Cloud Managed Network (CMN) Solution consists of the cloud management platform and a full range of cloud managed network devices. The cloud management platform provides various functions including management of APs, tenants, applications, and licenses, network planning and optimization, device monitoring, network service configuration, and value-added services.High Density Boost technologyHuawei uses the following technologies to address challenges in high-density scenarios, including access problems, data congestion, and poor roaming experience:SmartRadio for air interface optimization●Load balancing during smart roaming: The load balancing algorithm can work during smart roaming for load balancing detection among APs on the network after STA roaming to adjust the STA load on each AP, improving network stability.●Intelligent DFA technology: The dynamic frequency assignment (DFA) algorithm is used to automatically detect adjacent-channel and co-channel interference, and identify any 2.4 GHz redundant radio. Through automatic inter-AP negotiation, the redundant radio is automatically switched to another mode (dual-5G AP models support 2.4G-to-5G switchover) or is disabled to reduce 2.4 GHz co-channel interference and increase the system capacity.●Intelligent conflict optimization technology: The dynamic enhanced distributed channel access (EDCA) and airtime scheduling algorithms are used to schedule the channel occupation time and service priority of each user. This ensures that each user is assigned relatively equal time for using channel resources and user services are scheduled in an orderly manner, improving service processing efficiency and user experience.5G-prior access (Band steering)●The APs support both 2.4G and 5G frequency bands. The 5G-prior access function enables an AP to steer STAs to the 5 GHz frequency band first, which reduces load and interference on the 2.4 GHz frequency band, improving the user experience.Wired and wireless dual security guarantee●To ensure data security, Huawei APs integrate wired and wireless security measures and provide comprehensive security protection.Authentication and encryption for wireless access●The APs support WEP, WPA/WPA2–PSK, WPA/WPA2–PPSK, WPA/WPA2–802.1X, WPA3-SAE, WPA3–802.1X,and WAPI authentication/encryption modes to ensure security of the wireless network. The authentication mechanism is used to authenticate user identities so that only authorized users can access network resources. The encryption mechanism is used to encrypt data transmitted over wireless links to ensure that the data can only be received and parsed by expected users.Analysis on non-Wi-Fi interference sources●Huawei APs can analyze the spectrum of non-Wi-Fi interference sources and identify them, including baby monitors, Bluetooth devices, digital cordless phones (at 2.4 GHz frequency band only), wireless audio transmitters (at both the 2.4 GHz and 5 GHz frequency bands), wireless game controllers, and microwave ovens. Coupled with Huawei eSight, the precise locations of the interference sources can be detected, and the spectrum of them displayed, enabling the administrator to remove the interference in a timely manner.Rogue device monitoring●Huawei APs support WIDS/WIPS, and can monitor, identify, defend, counter, and perform refined management on the rogue devices, to provide security guarantees for air interface environment and wireless data transmission.AP access authentication and encryption●The AP access control ensures validity of APs. The CAPWAP link protection and DTLS encryption provide security assurance, improving data transmission security between the AP and the AC.Automatic radio calibration●Automatic radio calibration allows an AP to collect signal strength and channel parameters of surrounding APs and generate AP topology according to the collected data. Based on interference from authorized APs, rogue APs, and non-Wi-Fi interference sources, each AP automatically adjusts its transmit power and working channel to make the network operate at the optimal performance. In this way, network reliability and user experience are improved.Automatic application identificationHuawei APs support smart application control technology and can implement visualized control on Layer 4 to Layer 7 applications.Traffic identification●Coupled with Huawei ACs, the APs can identify over 1600 common applications in various office scenarios. Based on the identification results, policy control can be implemented on user services, including priority adjustment, scheduling, blocking, and rate limiting to ensure efficient bandwidth resource use and improve quality of key services.Traffic statistics collection●Traffic statistics of each application can be collected globally, by SSID, or by user, enabling the network administrator to know application use status on the network. The network administrator or operator can implement visualized control on service applications on smart terminals to enhance security and ensure effective bandwidth control.Basic SpecificationsFat/Fit AP modeCloud-based management modeTechnical SpecificationsStandards complianceAntennas Pattern2.4G (PHI=0) 2.4G (PHI=90)5G (PHI=0)5G (PHI=90)Ordering InformationMore InformationFor more information about Huawei WLAN products, visit or contact us in the following ways: ●Global service hotline: /en/service-hotline●Logging in to the Huawei Enterprise technical support web: /enterprise/●Sending an email to the customer service mailbox: ********************Copyright © Huawei Technologies Co., Ltd. 2020.

802.11ac 和802.11N 使用技术文章分析一、概述由于多数的802.11n设备是为2.4GHz频段设计，2.4GHz本身的可用信道较少，同时还有其它工作于2.4GHz 频段的设备(例如蓝牙，微波炉、无线监视摄像机等)的干扰，即使在双空间流40Mhz频宽下其连接速率能达到300Mbps，但是实际网络环境中，由于相互的信道冲突等原因，其实际吞吐并不高，用户体验差。

802.11ac 是专门为5GHz频段设计，特有的新射频特点，能够将现有的无线局域网的性能吞吐提高到可以与有线千兆级网络相媲美的程度。

802.11ac作为IEEE 无线技术的新标准，它借鉴了802.11n的各种优点并进一步优化，除了最明显的高吞吐特点外，不仅可以很好地兼容802.11a/n的设备，同时还提升了多项用户体验。

在802.11ac的网络中，每个无线接入点可以接纳更多的客户端，为每个并行的业务流提供更多的带宽，同时具有更低时延更省电的优点。

二、802.11ac 主要技术特征由于802.11n在MAC层已经很优异了，因此802.11ac在MAC层上的改进并不多，主要通过PHY层来提升其基础速率。

PHY层的改进1、更密的调制模式802.11ac继续采用802.11a中OFDM调制方法，但是将阶数从802.11n中的64阶提高到了256阶。

256-QAM 使得每个子载波的数据比特数从6提到8，从而使得速率增加了将近33%。

由于256-QAM对干扰更加敏感，适合于信噪比高的环境，因此256阶正交调幅主要在64阶正交调幅已经可靠覆盖的范围内才有帮助。

虽然256-QAM提供了更高的速率，但是它并没有增加有效的覆盖距离。

例外，不像802.11n中那样可以采用非等星座调制，在802.11ac中，当多条流同时发送时，每条流都必须采用同等大小的星座。

而前者对于多空间流特别是波束成形来说却非常有益。

2、更宽的信道带宽由于5GHZ频段可以提供更多的信道和更宽的频宽，802.11ac 将信道频宽从802.11n的20MHZ和40MHZ提升到了80MHZ，甚至是160MHZ。

Minimizing radio interference. When integrating the WiFlymodule with on board chip antenna make sure the area around the chip antenna end the module protrudes at least 6mm from the mother board PCB and any metal enclosure. Ifthis is not possible use the on board U.FL connector to route to an external Antenna.The 8.5 mm area under the antenna end of the moduleshould be keep clear of metallic components, connectors, vias, traces and other materials that can interfere with the radio signal. 2. Proper grounding. For the module antenna to function pins36- to 44 must be connected to GND. We suggest you place module such that 0.5mm of theses pads is exposed. This provides access for soldiering pins 36 through 44 from below and provides ample clearance of the antenna from the PCB.3. Solder Reflow. Reflow temperature must not exceed 220C.To reflow solder the RN-131G and RN-131C module onto a PCB Roving recommends a RoHS compliant solder paste equivalent to the NIHON ALMIT paste or OMNIX OM-310 solder paste from Alpha metals. NOTE: Use no clean Flux, Do NOT water wash!Note also, that the temperature profile is based on the IC level and other components level only (without the shield can). So if we go on module perspective, above 245C profile should be acceptable.In fact the module temperature profile specifications tells, that you should be able to go beyond 240C (from 220C[60secs] to 250C[10secs]). The module temperature profile diagram is shown below.Bottom vie w Mother Board For RN-1318.5 mm For proper antennaPerformance p in s 36 through 44 mu st begrounded Top view4. U.FL connector. Use Hirose U.FL connector U.FL-R-SMT to for connecting external antennas. See RovingNetworks U.FL to SMA cable. Part number: RN-UFL-SMA65. Connection Status. GPIO-4, GPIO-5, GPIO-6 are available to drive a status LEDs. GPIO-6 indicates TCP/IPconnection status. This signal is ON high for an active connection, toggles fast to indicate no IP address and toggles slow indicates IP address OK but not connection. GPIO-4 indicates association status. High means not associated with a network, Off indicates associated and Internet access is OK. GPIO-5 toggles when data is transferred.6. Keep out areas. When designing your PCBavoid exposed trace and via beneath the module.7. Powering the module. The WiFly module canbe powered from either 3.0VDC batteries or 3.3VDC regulated power.3.0VDC battery power• Apply power to pin 20 (VDD-BATT) • Short pin 17 (3.3V-REG-OUT) to pin 18(3.3V-REG-IN) (battery boost mode) • 150mA of current at 3.3V available forexternal devices on pin 21 when in battery boost mode.3.3 VDC power• Apply power to pin 20(VDD-BATT) and pin 21 (VDD-IN)• Connect pin 18 (3.3V-REG-IN) to ground and leave pin 17 (3.3V-REG-OUT) unconnected.8. Achieving lowest power in sleep modeTo achieve the lowest power consumption (4uA) in sleep mode connect a weak pull down (100K resistor to GND) on the following pin.Pin 22 - DMA-TXIf GPIO-8 through GPIO-4 are being used to drive an output, connect a 100k pull down resistor. Any GPIOs not used (No connect) can be left floating.Pin 25 - GPIO-8 Pin 26 - GPIO-7 Pin 27 - GPIO-6 Pin 28 - GPIO-5 Pin 29 - GPIO-4Other GPIO lines: No pulldown needed, internal pulldown ( 80K ) already on chip.The power consumption in sleep mode without these signals connected to a pull down is 655uA9. Sensor Interfaces. Inputs must not exceed 1.2V. Sensitivity saturates at 400 mV.10. Adhoc mode and Restoring Factory Settings. Adhoc mode is controlled through GPIO-9.

802.1as协议实现原理802.1as协议是用于以太网时钟同步的一种网络协议，它可以实现网络中各个设备之间的时钟同步，确保系统的时钟准确性。

本文将介绍802.1as协议的实现原理。

一、基本概述802.1as协议是以太网的一种扩展协议，它基于IEEE 1588协议，并对其进行了改进和扩展。

它主要用于工业自动化和音视频应用领域，要求网络设备之间的时钟误差在纳秒级别，以确保数据在不同设备之间的同步。

802.1as协议采用主从模式，其中一个设备作为主时钟，其他设备作为从时钟。

二、时钟同步方案802.1as协议使用时钟同步方案来实现网络设备之间的时钟同步。

时钟同步方案主要包括主时钟和从时钟之间的同步过程以及同步算法。

1. 主时钟和从时钟同步过程主时钟通过发送时间同步消息来告知从时钟当前的时间，从时钟接收到该消息后进行相应的调整，使得从时钟与主时钟保持同步。

主时钟和从时钟之间的同步过程需要考虑网络延迟、时钟抖动、带宽限制等因素。

2. 同步算法802.1as协议采用一种称为时间同步精确度(TSA)的算法来调整设备时钟。

TSA算法根据主时钟和从时钟之间的时间差，计算出从时钟应该进行的调整值，以保证时钟的同步精度。

三、时间同步消息802.1as协议中定义了一种称为Sync/Follow_Up消息的时间同步消息类型用于主时钟和从时钟之间的通信。

Sync/Follow_Up消息由主时钟周期性地发送给从时钟，其中包含了主时钟的当前时间信息。

从时钟接收到Sync/Follow_Up消息后，可以根据主时钟的时间信息来调整自身的时钟。

四、时钟源和时钟校正802.1as协议中规定了两种类型的时钟源：主时钟和从时钟。

主时钟作为网络中的主时钟源，负责向从时钟发送时间同步消息。

从时钟接收到时间同步消息后，即可根据主时钟的时间信息来校正自身的时钟。

时钟校正是指根据收到的时间同步消息，对从时钟进行调整，使其与主时钟保持同步。

时钟校正可以通过一种称为时钟校正跟踪(Correction Tracking)的技术来实现，该技术可以动态地调整从时钟的速率和相位，以使其与主时钟保持一致。
