<p><span>挪威奥斯陆</span><span>–2021</span><span>年</span><span>1</span><span>月</span><span>7</span><span>日<span> </span></span><span>– Nordic Semiconductor</span><span>宣布总部位于日本东京的科技企业</span><span>IoTBank</span><span>在</span><span>其</span><span>“Mamosearch 2”</span><span>跟踪网关设备</span><span>中采用</span><span>Nordic</span><span>带有集成式</span><span>LTE-M/NB-IoT</span><span>调制解调器和</span><span>GPS</span><span>的</span><span>nRF9160</span><span>低功耗系统级封装</span><span>(SiP)</span><span>器件。这款网关产品还使用了</span><span>Nordic</span><span>的</span><span>nRF52832</span><span>低功耗</span><span>蓝牙</span><em><span> </span></em><span>(</span><em>Bluetooth</em><span>®</span><span><span> </span>Low Energy /Bluetooth LE)</span><span><span> </span></span><span>芯片级系统</span><span>(SoC)</span><span>。</span></p>
<p><span>Mamosearch 2</span><span>是一款可连接的便携式跟踪设备，主要用于监控受照顾者</span><span>/</span><span>处于危险中个人的位置，例如上学或放学途中的儿童、独居的老年家人或老年护理机构中的人员。这款设备亦可用于跟踪工业和商业资产。</span></p>
<p><span>借助</span><span>nRF9160 SiP</span><span>的</span><span>LTE-M</span><span>连接和</span><span>GPS</span><span>功能，配合内置</span><span>Wi-Fi</span><span>的三角测量功能，</span><span>Mamosearch 2</span><span>无需使用</span><span>GPS</span><span>即可进行精确的定位。跟踪器通过蜂窝网络定期将被跟踪物品的位置信息发送到基于云的专有平台和仪表板。这样，消费者或资产管理者可以在其蓝牙</span><span>4.0(</span><span>及更高版本</span><span>)</span><span>智能手机上通过</span><span>iOS</span><span>和安卓的</span><span><span> </span>“Mamosearch”</span><span>应用程序进行远程监控。</span></p>
<p><span>nRF9160 SiP</span><span>器件的</span><span>64 MHz<span> </span></span><span>Arm®Cortex®-M33</span><span>处理器提供了充足的计算能力，可以运行</span><span>LTE-M</span><span>蜂窝连接</span><span>及</span><span>所有其他的产品功能。其</span><span>1MB</span><span>闪存和</span><span>256KB RAM</span><span>支持快速响应和复杂的应用程序软件。通过利用</span><span>nRF9160</span><span>的紧凑尺寸</span><span>(10 x 16 x 1 mm)</span><span>优势，</span><span>Mamosearch 2</span><span>跟踪器可将</span><span>SiP</span><span>器件、</span><span>Wi-Fi</span><span>芯片组、电池、</span><span>Wi-Fi</span><span>和蜂窝天线集成到尺寸仅为</span><span>45 x 45 x 15 mm</span><span>并且重量只有</span><span>36g</span><span>的设备中。在正常使用情况下，这款跟踪器一次充电即可使用大约一个月时间，或者</span><span>支持</span><span>三个月的待机时间，这在一定程度上要归功于</span><span>Nordic SiP</span><span>器件的超低功耗特性。</span></p>
<p><span>除了</span><span>nRF9160 SiP</span><span>之外，</span><span>Mamosearch 2</span><span>网关产品还集成了</span><span>Nordic</span><span>的</span><span>nRF52832 SoC</span><span>，可以提供低功耗蓝牙连接功能，支持商业</span><span>/</span><span>工业资产跟踪应用，例如管理工厂、仓库或建筑工地中物料的位置。低功耗蓝牙功能意味着任何蓝牙信标都可以将位置通知网关。</span><span>(</span><span>蓝牙信标在全球范围内广泛使用，提供了确定资产固定位置的可靠方法。</span><span>)</span><span>使用</span><span>nRF9160</span><span>的</span><span>LTE-M</span><span>蜂窝连接功能，可以将信标的位置数据中继传输到云端，从而允许管理人员通过配套应用程序同时跟踪多个资产。</span></p>
<p><span>nRF9160 SiP</span><span>通过了全球蜂窝物联网应用认证，包含专用应用处理器和存储器、具有集成式</span><span>RF</span><span>前端</span><span>(RFFE)</span><span>的多模</span><span>LTE-M/NB-IoT</span><span>调制解调器、</span><span>GPS</span><span>和电源管理。这款</span><span>SiP</span><span>器件集成了</span><span>Arm M33</span><span>处理器、闪存和</span><span>RAM</span><span>、一系列模拟和数字外设、自动化电源和时钟管理，用于可信执行的</span><span>ArmTrustZone®</span><span>和用于应用层安全性的</span><span>Arm CryptoCell™ 310</span><span>。处理器通过</span><span>BSD</span><span>安全套接字</span><span>API</span><span>与</span><span>LTE</span><span>调制解调器进行通信，并支持应用层协议</span><span>(</span><span>例如</span><span>CoAP</span><span>、</span><span>MQTT</span><span>或</span><span>LWM2M)</span><span>和应用程序本身。</span><span>nRF9160 SiP</span><span>的</span><span>LTE</span><span>调制解调器支持</span><span>SIM</span><span>和</span><span>eSIM</span><span>，提供</span><span>700</span><span>至</span><span>2200 MHz</span><span>的</span><span>LTE</span><span>频段支持，</span><span>23 dBm</span><span>的输出功率以及单针</span><span>50Ω</span><span>天线和</span><span>UICC</span><span>接口。其调制解调器固件包含</span><span>LTE</span><span>堆栈层</span><span>L1-L3</span><span>、</span><span>IPv4/IPv6</span><span>、</span><span>TCP/UDP</span><span>和</span><span>TLS/DTLS</span><span>。</span></p>
<p><span>相关产品包括预认证单板开发套件</span><span>nRF9160 DK</span><span>和软件开发套件</span><span>nRF Connect SDK</span><span>，其中包括应用层协议、应用示例，</span><span>并提供</span><span>预认证和预编译的</span><span>LTE</span><span>调制解调器固件下载</span><span>软件</span><span>。</span></p>
<p><span>Nordic</span><span>的</span><span>nRF52832</span><span>多协议</span><span>SoC</span><span>具有带有浮点单元</span><span>(FPU)</span><span>的功能强大</span><span>64MHz</span><span>、</span><span>32</span><span>位</span><span>Arm Cortex M4</span><span>处理器，具有</span><span>-96dBm RX</span><span>灵敏度的</span><span>2.4GHz</span><span>无线电功能，超过</span><span>100dBm</span><span>的总体链路预算，以及充足的</span><span>512kB</span><span>闪存和</span><span>64kB<span> </span></span><span>内存。</span></p>
<p><span>IoTBank</span><span>首席执行官曲亮先生说：</span><span>“</span><span>我们选择</span><span>Nordic</span><span>的</span><span>nRF9160 SiP</span><span>用于</span><span>Mamosearch 2</span><span>跟踪网关设备，是因其低功耗特性，而使用</span><span>Nordic nRF52832 SoC</span><span>则是由于其提供的稳定网络通信。</span><span>”</span></p>
<p><span>“Nordic</span><span>工程师提供的强大技术支持，在产品开发阶段发挥了关键作用，帮助加快了产品上市速度。</span><span>”</span></p>
