Smart cities through the Internet of Things (IoT) can tackle significant challenges that residents face – public safety, traffic, air quality, lighting, public transportation, and much more. Imagine a city that has sensors that records traffic patterns. That data is analyzed, and then traffic signals can adjust to the needs of traffic anonymously. Bus routes can be optimized and digitized to reduce waiting time and increase utilization to avoid waste. When it comes to smart cities – whether getting started deploying or creating solutions that can be used in smart cities applications, there are several key technologies that have been identified by recent research to consider.

Smart parking can help drivers find parking with ease and enhance safety with surveillance cameras. License plate recognition cameras can help manage traffic violations or investigate crimes. Cameras can be equipped with gunshot detection to alert law enforcement in real time. Numerous components can be built into smart cities, and the opportunity is growing as the Internet of Things has become more achievable through more affordable devices, widespread cellular connectivity, and a strong IoT vendor ecosystem to make deploying, managing, and scaling solutions simpler.

eSIM to Manage Connectivity Challenges

When deploying devices in IoT, one of the more significant challenges is unified connectivity, particularly for those organizations that are selling IoT solutions.

Consider this as an example: An organization has decided to sell a camera that is designed for license plate recognition as part of a smart city’s vertical-oriented offering. This organization wants to be able to sell this camera across North America and Europe with connectivity that works out of the box. The camera can record, take snapshots of critical events, and send this data cellularly to a centralized platform, so the connectivity element is extremely important.

Now, as the organization does not know the demand per region or carrier preference of the end user, it would make sense to use a carrier-agnostic SIM card, such as an eSIM, that can be provisioned remotely once an order has been placed.

This reduces the number of SKUs for the organization to just a single SKU, and it ensures that they can meet the demand of the end user, no matter where they are located or the carrier they use.

For those deploying smart city applications, an eSIM helps protect against network or carrier changes in the future. The 2G and 3G sunsets have shed light on the need for a connectivity technology that is resilient against changes to legacy networks or open to the possibility of future network technologies.

Instead of physically swapping each SIM in each device within the smart cities’ application – which could be thousands of devices, some in hard-to-reach areas – the eSIM can be remotely provisioned to connect to the new network of choice.

Private Networks to Support Data Requirements

If a city or municipality were to leverage smart city applications and connect hundreds or thousands of devices, a private network can be a consideration for managing that data load. While private networks through a wired network might be a traditional method, 4G LTE or 5G cellular networks can be utilized for private networks to support widespread, cellular devices while maintaining speed and bandwidth.


A private network could be built to only support the smart cities application, which means dedicated bandwidth that would not experience lags or slowdowns by sharing the network with other applications. This could help ensure that the smart cities devices are sending and receiving data consistently as expected.

Device authentication through private networks can help support a secure cellular IoT application, as well. Some uses of IoT in smart cities could expose sensitive data, like data used to help law enforcement investigate crimes.

智慧城市数字化解决方案
通过物联网(IoT)建设的智慧城市可以解决居民面临的重大挑战——公共安全、交通、空气质量、照明、公共交通等等。想象一下,一个城市拥有记录交通模式的传感器。这些数据被分析,然后交通信号可以根据交通需求进行匿名调整。巴士路线可以优化和数字化,以减少等待时间,提高利用率,避免浪费。谈到智能城市,无论是开始部署还是创建可用于智能城市应用程序的解决方案,最近的研究已经确定了几个关键技术。智能停车可以帮助司机轻松找到停车位,并通过监控摄像头提高安全性。车牌识别摄像头可以帮助管理交通违规或调查犯罪。摄像头可以配备枪击探测功能,实时提醒执法部门。智能城市中可以内置大量组件,随着物联网变得越来越容易实现,物联网通过更实惠的设备、广泛的蜂窝连接和强大的物联网供应商生态系统使部署、管理和扩展解决方案变得更简单,机会也越来越大。当在物联网中部署设备时,更重要的挑战之一是统一连接,特别是对于那些销售物联网解决方案的组织来说。举个例子:一个组织决定销售一款专为车牌识别设计的摄像头,作为智能城市垂直导向产品的一部分。该组织希望能够在北美和欧洲各地销售这款相机,并提供开箱即用的连接。摄像机可以记录、拍摄关键事件的快照,并将这些数据发送到集中的平台,因此连接元素非常重要。现在,由于组织不知道每个地区的需求或最终用户的运营商偏好,因此使用与运营商无关的SIM卡(如eSIM)是有意义的,一旦下了订单,就可以远程提供。这将组织的SKU数量减少到单个SKU,并确保它们能够满足最终用户的需求,无论他们位于何处或他们使用的运营商。对于部署智能城市应用程序的企业来说,eSIM有助于防止未来网络或运营商的变化。2G和3G的衰落揭示了对一种连接技术的需求,这种技术既能抵御传统网络的变化,也能对未来网络技术的可能性保持开放。在智能城市的应用程序中,可能有成千上万的设备,其中一些在难以到达的地区,而不是在每个设备中物理地交换每个SIM卡,eSIM可以远程配置以连接到所选择的新网络。如果一个城市或市政当局要利用智能城市应用程序并连接数百或数千台设备,则可以考虑使用专用网络来管理数据负载。虽然通过有线网络的专用网络可能是一种传统方法,但4G LTE或5G蜂窝网络可以用于专用网络,以支持广泛的蜂窝设备,同时保持速度和带宽。可以构建专用网络,仅支持智能城市应用程序,这意味着专用带宽不会因与其他应用程序共享网络而出现延迟或变慢。这有助于确保智能城市设备能够按照预期一致地发送和接收数据。通过专用网络进行设备身份验证也有助于支持安全的蜂窝物联网应用程序。物联网在智能城市中的一些应用可能会暴露敏感数据,比如用于帮助执法部门调查犯罪的数据。
