<p><em>nRF9160 SiP</em><em>认证可让物联网产品开发人员</em><span>受惠于</span><em>世界最大型</em><em>NB-IoT</em><em>网络</em></p>

<p><span>挪威奥斯陆</span><span><span>&nbsp;</span>– 2020</span><span>年</span><span>10</span><span>月13日</span><span><span>&nbsp;</span>–</span><span><span>&nbsp;</span></span><span>Nordic Semiconductor</span><span>宣布其</span><span>屡获殊荣并且</span><span>集成了</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>产品已经通过认证，可用于中国电信的</span><span>NB-IoT</span><span>网络。根据全球行业机构</span><span>GSMA</span><span>的数据，中国电信目前通过</span><span>40</span><span>多万个</span><span>NB-IoT</span><span>基站为超过</span><span>5,000</span><span>万客户提供服务，这相当于接近</span><span>98%</span><span>的</span><span>全国覆盖率。这项认证使得部署了</span><span>nRF9160 SiP</span><span>的产品设计能够为中国电信客户实现</span><span>NB-IoT</span><span>连接。</span></p>

<p><span>nRF9160</span><span>是经认证用于全球蜂窝物联网应用的低功耗</span><span>SiP</span><span>器件，其紧致封装中包含了集成</span><span>RF</span><span>前端</span><span>(RFFE)</span><span>的多模式</span><span>LTE-M/NB-IoT</span><span>调制解调器、</span><span>GPS</span><span>和电源管理，其中的</span><span>64 MHz</span><span>处理器带有</span><span>1 MB</span><span>闪存和</span><span>256 KB RAM</span><span>，还有各种模拟和数字外设、自动电源和时钟管理，以及用于可信执行的</span><span>Arm TrustZone™</span><span>和用于应用层安全性的</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>输出功率和单针</span><span>50Ω</span><span>天线及</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</span><span>到</span><span>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>配合</span><span>nRF9160 DK</span><span>预认证单板开发套件以及可供下载的预认证和预编译</span><span>nRF Connect SDK</span><span>软件开发套件</span><span>(</span><span>包含应用层协议、应用示例和</span><span>LTE</span><span>调制解调器固件</span><span>)</span><span>的支持，</span><span>nRF9160 SiP</span><span>的目标应用包括资产跟踪、智慧城市、智能农业、工业、智能计量、可穿戴设备和医疗解决方案等。</span></p>

<p><span>Nordic Semiconductor</span><span>亚太区销售与营销总监</span><span>Bjørn Åge “Bob” Brandal</span><span>表示：“</span><span>NB-IoT</span><span>正于全球范围内取得显着增长，其中以中国市场最为突出。由于公共服务和企业服务的需求推动，特别是在智能水表和燃气表方面，每年都有数以千万计的新</span><span>NB-IoT</span><span>连接上线；而且，凭借</span><span>Nordic Semiconductor</span><span>前所未有的高集成度、小尺寸和超低功耗特性，追踪器和可穿戴设备等消费类应用以及其</span><span>它</span><span>应用中的全新</span><span>NB-IoT</span><span>连接亦越来越多。”</span></p>

<p><span>“业界公认中国电信是中国</span><span>NB-IoT</span><span>服务的先驱，现在，使用</span><span>Nordic nRF9160 SiP</span><span>进行设计的开发人员将能够受惠于这</span><span>个卓越</span><span>的规模化网络。”</span></p>

<p><span>获得中国电信的认证前，</span><span>nRF9160 SiP</span><span>早已通过了全球范围多家其他电信商的认证，包括德国电信</span><span><span>&nbsp;</span>(</span><span>用于德国的</span><span>LTE-M</span><span>网络和奥地利、捷克共和国、德国、克罗地亚、荷兰、波兰和斯洛伐克的</span><span>NB-IoT</span><span>网络</span><span>)</span><span>、</span><span>Verizon</span><span>和</span><span>AT&amp;T(</span><span>用于美国的</span><span>LTE-M</span><span>网络</span><span>)</span><span>、沃达丰</span><span>(</span><span>用于澳大利亚、捷克共和国、德国、希腊、匈牙利、爱尔兰、意大利、马耳他、新西兰、葡萄牙、西班牙、南非、荷兰、土耳其、英国和乌克兰的</span><span>NB-IoT</span><span>网络</span><span>)</span><span>和</span><span>Telstra(</span><span>用于澳大利亚</span><span>LTE-M</span><span>网络</span><span>)</span><span>。</span></p>
