CATM有什么区别 & CAT1 ?

CATM和CAT1是两种不同的LTE通信标准, 它们的主要区别在于应用场景和特点.

计算机辅助技术管理, LTE-M 的缩写, 是 3GPP 开发的低成本 LPWAN 技术,作为 LTE 标准版本的一部分 13. CAT-M可以满足更高的数据速率和低延迟通信. 如果用户需要从特定 IoT 设备收集大型文件或将大型更新推送到 IoT 端点, Cat-M是最佳选择. Cat-M1 支持基于基站的切换, 使其适合与移动应用程序一起使用,例如资产跟踪和车队管理. 它还支持物联网应用中的语音功能.

CAT1, Cat-1 的缩写, 是另一种旨在服务物联网的 LTE 通信标准. 它缩小了带宽和通信要求, 为大规模或远程物联网系统节省电力和成本. 猫 1 可应用于带宽要求不高但对功耗和数据传输稳定性有一定要求的场景, 例如车队管理, 可穿戴设备, 校园水治理, 充电站, 智能安防, 智慧农业, 智能家电, 工业传感器, 港口物流跟踪, ETC.

全面的, CATM和CAT1是低功耗广域网 (低功耗广域网) 专为物联网设备设计的技术. 它们的主要区别在于数据传输速率和延迟. CATM 性能优于 CAT1, 但CAT1成本较低,更适合带宽要求较低的场景.
