可靠的通信不能总是依赖蜂窝网络、固定基站或现有网络基础设施。在应急响应、移动作业、偏远地区和快速变化的野外环境中,可能需要在人员、车辆和无人系统运行的任何地方建立通信网络。

我们的 MANET 无线电台系统采用宽带网状组网和软件无线电技术,为语音、视频、数据和位置信息创建灵活的无线 IP 网络。多个无线节点可建立直接或多跳链路,使手持终端、车辆、无人机、摄像头和指挥中心在分布式作业区域内保持连接。

从便携式野外通信到移动指挥和机载组网,MANET 电台提供了一种实用的方式,可在不完全依赖固定基础设施的情况下部署宽带通信。

MANET 电台的主要特点

自组网网状网络

自组网网状网络

MANET 电台能够在参与节点之间建立通信链路,而无需每台设备直接连接到固定的中心基站。随着电台加入网络,它们可以成为整体通信路径的一部分,并与其他可达节点交换 IP 流量。

多跳中继

当两台电台由于距离、地形或障碍物而无法直接通信时,中间节点可以在它们之间中继流量。因此,车载电台、背负式节点或固定站可以帮助将通信扩展到单台手持设备直接无线电范围之外。

多跳中继
动态网络路由

动态网络路由

人员、车辆和无人机在野外行动中不断移动。MANET 网络可以随着可用通信链路的变化进行调整,有助于在整个移动网络中保持连接,而不是依赖一条永久固定的传输路径。

宽带语音、视频和数据

与主要围绕窄带语音设计的传统无线电系统不同,宽带 MANET 电台提供能够支持不同通信服务的 IP 传输网络。根据系统配置和可用带宽,同一个无线网络可以承载语音通信、实时视频、行动数据和位置信息。

宽带语音、视频和数据

基于 SDR 的电台架构

软件定义无线电架构为无线通信提供了灵活的基础。电台处理功能可以通过可编程硬件和软件实现,从而使不同的电台产品能够适用于手持、车载、机载和固定站点应用。

MIMO 无线传输

MIMO 无线传输

MIMO 技术利用多个发射和接收路径来提升无线通信性能。这对于宽带网状网络尤其有用,因为节点可能在移动、受遮挡或多径环境中运行。

IP 设备连接

MANET 电台可构成基于 IP 的现场设备的无线传输层。摄像头、计算机、传感器、移动终端和其他网络设备可根据所选电台型号提供的接口和功能进行连接。

产品优势

语音通信

语音通信

现场人员与行动团队可根据系统架构及所连接的终端,使用该网络支持语音通信应用。

实时视频传输

实时视频传输

来自便携式摄像机、车载摄像机、无人机载荷和观察点的视频可通过宽带网状网络传输,帮助指挥人员获取远程位置的视觉信息。

运行数据

运行数据

计算机、传感器、控制器及其他基于IP的设备可通过无线网络交换运行信息。

位置与GIS信息

位置与GIS信息

来自移动设备的位置信息可发送至兼容的指挥或调度平台,使操作人员更清楚地掌握人员、车辆及其他网络资产的位置。

无人系统连接

无人系统连接

无人机、机器人及其他无人设备可成为宽带现场网络的一部分,使来自偏远或难以到达区域的信息能够传递至行动团队。

应用场景

应急
救援
安防
无人机
指挥
Utilities
矿业
野外作业

自然灾害、重大事故及基础设施故障可能中断现有通信服务。MANET 无线电可让应急团队利用便携式、车载式及固定式通信节点快速建立独立的无线网络。 随后,语音、实时视频、定位信息及作业数据可在现场团队与临时指挥中心之间传输。

应急

消防与救援行动通常涉及位置不断变化、复杂地形及有限的网络覆盖。手持无线电、车载节点、临时中继及机载平台可组合使用,在事故区域周边建立移动通信网络

救援

MANET 无线电可支持临时安保行动、巡逻团队、大型活动通信,以及其他需要在移动人员与指挥位置之间快速部署无线网络的场景。

安防

机载 MANET 节点可为无人机视频与数据传输提供宽带链路,同时参与更大范围的空地 Mesh 自组网。 这使无人机能够与指挥车、现场人员及固定站点协同工作,而不是作为完全独立的通信链路运行。

无人机

配备 MANET 无线电的指挥车可成为移动网络枢纽,连接现场人员、摄像机、无人机、远程节点及指挥应用。 当指挥位置需要随行动移动,而不是固定在某个通信设施内时,这种方式尤其适用。

指挥

输电线路、管道巡检、测绘及其他公用事业作业经常在偏远环境中进行。当固定通信条件有限时,MANET 无线电可在现场团队与移动作业中心之间提供临时宽带连接。

Utilities

大型工业场地、露天矿区及偏远项目区域可能存在通信覆盖盲区或临时作业区。便携式与车载式 Mesh 节点可为现场视频、数据传输及作业协调提供额外的通信方式。

矿业

测绘、勘探、巡检及临时工程项目可利用 MANET 网络,在人员、车辆与远程设备之间快速建立通信,而无需先部署永久性网络基础设施。
