Raltron为智能城市应用，提供了最全面的频率管理组件线，从简单的音叉晶振到高稳定性温度补偿晶体振荡器和天线。这些产品旨在满足这个不断增长的市场的超低功耗、小足迹和低成本的需求。
什么是智能城市？
一个智慧城市是一个利用先进的技术和数据驱动的解决方案来提高其公民的生活质量和提高城市服务的效率的城市。为了实现这一目标，一个智能城市的目标是通过整合交通、能源、医疗保健和通信等各种组成部分，创建一个智能和可持续的生态系统
为了实时收集和分析数据，智能城市使用传感器、数据分析和物联网（IoT）设备。这些数据可以帮助城市管理者做出明智的决策，并优化资源分配。通过利用技术，一个智能城市可以改善流动性，减少碳排放，提高安全性，并促进经济增长。
智慧城市为应对城市挑战提供了一个很有前途的解决方案，并为公民创造了一个更美好的未来，特别是在全球人口不断增长和快速城市化的情况下。
