<p><span>挪威奥斯陆</span><span><span>&nbsp;</span></span><span>– 2021</span><span>年</span><span>2</span><span>月2</span><span>5</span><span>日</span><span><span>&nbsp;</span>–<span>&nbsp;</span></span><span>Nordic Semiconductor</span><span>宣布位于美国密歇根州迪凯特的科技初创企业</span><span>Cube Tracker</span><span>在其</span><span><span>&nbsp;</span>“C7004 Cube GPS”<span>&nbsp;</span></span><span>跟踪设备中使用了带有集成</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。</span><span>Cube GPS</span><span>可让用户通过广泛且成熟的蜂窝基础设施来远程监视重要物品或个人的位置。</span></p>

<p><span>Cube GPS</span><span>是具有</span><span>IP67</span><span>等级防水性能并可连接的便携式跟踪设备，主要用于监视车辆、儿童，宠物和其他贵重物品的位置。在美国全国范围的覆盖率之下，跟踪器能够以</span><span>30</span><span>米以内的精度来监视物品或佩戴者的位置。</span></p>

<p><span>通过</span><span>nRF9160 SiP</span><span>的</span><span>LTE-M</span><span>连接功能和</span><span>GPS</span><span>支持，以及跟踪器的内置</span><span>Wi-Fi</span><span>功能</span><span><span>&nbsp;</span>(</span><span>用于室内和室外跟踪</span><span>)<span>&nbsp;</span></span><span>和低功耗蓝牙</span><span><span>&nbsp;</span>(Bluetooth Low Energy (Bluetooth LE))<span>&nbsp;</span></span><span>连接功能</span><span><span>&nbsp;</span>(</span><span>用于近距离监视</span><span>)</span><span>的辅助，这款产品利用蜂窝网络定期将所跟踪物品</span><span>/</span><span>个人的位置信息发送到云端；而用户可以通过智能手机上的</span><span>iOS</span><span>和</span><span>Android</span><span>版本</span><span>Cube Tracker</span><span>应用程序实现安全、可靠和</span><span><span>&nbsp;</span>“</span><span>实时</span><span>”<span>&nbsp;</span></span><span>的监控。另外，用户可以通过应用程序查看物品的位置历史记录，以及设置</span><span><span>&nbsp;</span>“</span><span>接近</span><span>时响</span><span>” (ring when close)<span>&nbsp;</span></span><span>和地理围栏警报。</span></p>

<p><span>nRF9160 SiP</span><span>的</span><span>64 MHz Arm® Cortex®-M33</span><span>处理器提供了充足的计算能力，不仅可以运行</span><span>LTE-M</span><span>蜂窝连接，还可以运行其他所有的产品功能。</span><span>1MB</span><span>闪存和</span><span>256KB RAM</span><span>支持复杂的应用程序软件，并且能够快速响应位置请求。</span><span>Cube GPS</span><span>利用</span><span>nRF9160</span><span>的紧凑尺寸</span><span><span>&nbsp;</span>(10 X 16 X 1mm)</span><span>，整合了</span><span>SiP</span><span>、</span><span>Wi-Fi /</span><span>低功耗蓝牙芯片组；</span><span>Wi-Fi</span><span>和蜂窝天线；一个可充电</span><span>500mAh</span><span>电池；一个电池和蜂窝状态</span><span>LED</span><span>指示器，以及用于紧急警报或自定义功能的按钮，而设备的尺寸仅约</span><span>70 x 40 x 16mm</span><span>。这款跟踪器可视乎可调节的</span><span>GPS</span><span>更新间隔而定，实现</span><span>10</span><span>至</span><span>60</span><span>天的电池使用寿命，这在一定程度上要归功于</span><span>Nordic SiP</span><span>的超低功耗特性。</span><span>nRF9160 SiP</span><span>针对低功耗运行进行了优化，支持</span><span>PSM</span><span>和</span><span>eDRX</span><span>节能模式。例如在</span><span>PSM</span><span>模式下每</span><span>12</span><span>小时上传</span><span>1 KB</span><span>数据，平均电流为</span><span>5.5 uA</span><span>。</span></p>

<p><span>nRF9160 SiP</span><span>已通过全球蜂窝物联网应用认证，在紧凑型封装中包含了专用应用处理器和存储器；带集成</span><span>RF</span><span>前端</span><span><span>&nbsp;</span>(RF front end, RFFE)<span>&nbsp;</span></span><span>的多模式</span><span>LTE-M/NB-IoT</span><span>调制解调器，</span><span>GPS</span><span>以及电源管理。这款</span><span>SiP</span><span>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>和用于应用程序层安全性的</span><span>Arm CryptoCell™ 310</span><span>。该处理器通过</span><span>BSD</span><span>安全套接</span><span>API</span><span>与</span><span>LTE</span><span>调制解调器进行通信，并支持应用程序层协议</span><span><span>&nbsp;</span>(</span><span>例如</span><span>CoAP</span><span>、</span><span>MQTT</span><span>或</span><span>LWM2M)<span>&nbsp;</span></span><span>和应用程序本身。</span><span>nRF9160 SiP</span><span>的</span><span>LTE</span><span>调制解调器同时支持</span><span>SIM</span><span>和</span><span>eSIM</span><span>，并提供</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。</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>、</span><span>TLS/DTLS</span><span>是调制解调器固件的一部分。</span></p>
