802.11n是一种无线局域网（WLAN）技术标准，旨在提高无线网络的速度和稳定性。

在802.11n标准中，有几种机制被用来提高吞吐量，从而改善无线网络的性能。

本文将介绍802.11n中用来提高吞吐量的机制，并对其原理和实际应用进行详细阐述。

一、MIMO技术MIMO是Multiple-Input Multiple-Output的缩写，即多输入多输出技术。

802.11n标准采用了MIMO技术，通过同时使用多个天线进行数据传输和接收，从而提高了无线网络的吞吐量。

MIMO技术能够在不增加频谱带宽的情况下，通过空间复用的方式提高数据传输速率，增强了信号的抗干扰性和覆盖范围。

利用MIMO技术，802.11n标准支持了1x1、2x2、3x3甚至4x4等不同数量的天线配置，能够实现更多数据的并行传输，提高了网络的整体性能。

MIMO技术还能够通过空间复用和波束成形等手段来提高信号的覆盖范围和可靠性，从而进一步提高了网络的吞吐量和稳定性。

二、帧聚合技术802.11n标准引入了帧聚合技术，通过将多个数据帧合并成一个更大的帧进行传输，从而提高了数据传输的效率和吞吐量。

在传统的802.11a/g标准中，每个数据帧都需要经过一定的信道竞争和保护间隔，从而导致了较为低效的信道利用率和较低的吞吐量。

而在802.11n标准中，通过帧聚合技术，可以将多个数据帧合并成一个更大的帧进行传输，减少了信道竞争的次数，提高了信道的利用效率，进而提高了网络的吞吐量。

帧聚合技术的引入显著改善了无线网络的性能，使得802.11n能够更好地满足多媒体数据传输等高吞吐量的应用需求。

三、频谱聚合技术802.11n标准还引入了频谱聚合技术，通过同时使用多个频段来传输数据，从而提高了无线网络的吞吐量。

在传统的802.11a/g标准中，无线网络只能使用2.4GHz或5GHz的某一个频段进行数据传输，因此受到了频谱资源的限制，无法充分利用现有的频谱资源来提高网络的吞吐量。

Because of its small form factor and extremely low power consumption, the RN-131G is perfect for mobile wireless applications such as asset monitoring, GPS tracking and battery sensors. The WiFly GSX module incorporates a 2.4GHz radio, processor, TCP/IP stack, real-time clock, crypto accelerator, power management and analog sensor interfaces. This complete solution is preloaded with software to simplify integration and minimizes development of your application. In the simplest configuration the hardware only requires four connections (PWR, TX, RX, GND) to create a wireless data connection. Additionally, the sensor interface provides temperature, audio, motion, acceleration and other analog data without requiring additional hardware. The WiFly GSX module is programmed and controlled with a simple ASCII command language.

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. It is a good idea toconnect pin 24, GPIO-9 to a switch or jumper connected to a pull up. When GPIO-9 is driven high at power upBottom view: The re are twopad s o n th e module.

manufacturer,network operators,andservice providers.It has found applications in mobile,data center,and enterprise networks.The SDN architecture has a centralized,programmable control plane that is separate from the data plane.SDN also provides the ability to control and manage virtualized resources and networks without requiring new hardware technologies.This is a major shift in networking technologies.The ITU ⁃T has been engaged in SDN standardization,and the European Telecommunications Standard Institute (ETSI)has been working on network function virtualization (NFV),which complements SDN.The Open Network Foundation (ONF)is a non⁃profit organization dedicated to promoting the adoption of open SDN.Recently,much work has been done on SDN to meet future network requirements.Network virtualization creates multiple virtual infrastruc⁃tures within a deployed infrastructure.These virtualized infra⁃structures can be created over a single physical infrastructure.Each virtual network can be isolated from each other and pro⁃grammed to meet user requirements in terms of resource func⁃tionality and capacity.This ensures that appropriate network resources are provided to the user.The SDN framework includes programmable control plane,data⁃forwarding plane abstraction,and methods to map the vir⁃tualized infrastructures onto the underlying physical network infrastructure.Key issues to be addressed are network resource isolation,network abstraction,topology awareness,quick reconfigurabili⁃ty,performance,programmability,management,mobility,secu⁃rity,and wireless network access.We received strong response to this call for papers on SDN from network operators,equipment manufacturers,universi⁃ties,and research institutes.Following a peer⁃review process,we selected nine papers for inclusion in this special issue.The first paper,“Network Function Virtualization Technolo⁃gy:Progess and Standardization ”discusses the main challeng⁃es in SDN faced by network carriers.This paper also discusses current standardization activities and research on NFV related to SDN.The second paper,“Service Parameter Exposure and Dy⁃namic Service Negotiation in SDN Environments,”discusses the ability of SDN to facilitate dynamic provisioning of network services.The paper focuses on two main aspects of the SDN framework:network abstraction and dynamic parameter expo⁃sure and negotiation.The

I G I T C W技术 研究Technology Study44DIGITCW2023.10从当前的网络发展形势来看，5G/LTE （长期演进）双网共存并存仍然是通信的主流趋势。

从用户角度出发，由于5G 网络的带宽大、网速快，使用感知更好。

倘若网络优化不完善、参数设置不合理等因素，导致大量5G 终端用户仍然驻留在4G 网络上，造成4G 网络负荷高、5G 网络空闲的高倒流现象，无法将5G 网络资源有效转换成为收入。

结合实际案例分析，我们摸索出了一套通过配置无线侧网络参数来解决5G 网络高倒流问题的策略和方法，提升5G 用户驻留比，提高5G 网络投资效益。

1 5G网络高倒流原因分析5G 网络高倒流小区定义：在4G 网络和5G 网络共同覆盖的区域，当该区域内的5G 用户产生的4G 流量占比大于30%，即定义为高倒流小区。

由于目前5G 网络处于建设期，网络覆盖范围相对于4G 网络存在一定的差距，其中一部分由于参数设置不合理，导致5G 网络的业务会回落至4G 网络，造成5G 流量倒流，5G 基站和4G 基站的负荷不均衡[1]。

1.1 5G网络覆盖分析运营商在5G 网络工程建设当中，为充分利用现有4G 杆塔资源进行建设，同时为降低投资，4G 网络与5G 网络基本都是共址建设。

前期在4G 网络建设过程中，为保证网络覆盖能力，天线多是占用最优势的点位，而5G 网络建设时只能依据现有天面剩余资源进行建设。

因此5G 天线安装时往往无法使用最佳天面位置，5G 网络覆盖能力与4G 网络相比存在较大差距，造成5G 网络深度覆盖能力弱于4G 网络。

1.2 无线参数分析4G/5G 的无线参数对5G 小区高倒流也存在影响，4G/5G 的互操作参数的配置策略会收缩5G 网络真实的覆盖范围。

包括空闲态的5G 用户驻留策略（4G/5G 网络间的小区重选流程）和连接态的驻留策略（4G/5G网络间的异系统切换与覆盖重定向流程）[2]。

为此提出主动队列管理下 大时滞网络路径拥塞控制算法。

首先利用主动队列管理算法对相邻路由节点网络路径的拥塞情况展开预测，进而分析网络 路由节点的队列状态;然后以优化后续节点队列、传输距离以及传输方向为目的，从路径概率选择、分组丢弃函数、WSN蚁 群路由选取三个角度优化网络路径，从而实现路径拥塞控制。

实验结果表明，上述算法能够有效缩短网络的传输时滞，且能 耗和丢包率较低，具有较高的应用价值。
