1 Overview
LTE Cat1
工信部 2020年1月1日起施行的《增强机器类通信系统频率使用管理规定（暂行）》中明确 eMTC 的频率为：
- eMTC 系统使用无线电频率应当取得无线电频率使用许可
- 已规划用于 LTE 的 800MHz、900MHz、1800MHz、1900MHz 和 2100MHz 等公众移动通信频段
- 已规划用于 LTE 的 1447-1467MHz 和 1785-1805MHz 等专用移动通信频段
Cat 1 首推国产芯片解决方案：紫光展锐 UIS8910DM
紫光展锐春藤 8910DM 采用 28nm 工艺，支 持LTE Cat.1 BIS、GSM 双模，上行速率 5Mbps，下行速率达 10Mbps，同时集成蓝牙、Wi-Fi 室内定位，还支持 VoLTE，相比 4G 模块，功耗相当低。
全球 4G LTE 运营商都是基于最低 3GPP Release 8 协议版本部署，所以无需升级网络，只需简单的参数配置，就能让Cat.1终端接入网络。
采用紫光展锐 UIS8910DM 的相关模组有：中国移动 ML302、有 方N58、广和通 L610、合宙 Air724、安信可 Ca-01

硬件开机：
- VBAT上电后，可以通过 PWRKEY 管脚启动模块，拉低 1.2s 以上之后模块会进入开机流程，软件会检测 VBAT 管脚电压，若 VBAT 管脚电压大于软件设置的开机电压（3.1V），会继续开机动作直至系统开机完成；否则，会停止执行开机动作，系统会关机，开机成功后 PWRKEY 管脚可以释放。可以通过检测 V_GLOBAL_1V8 管脚的电平来判别模块是否开机
- 从拉低 PWRKEY，到 UART 可用，应等待 18s 以上
- 从拉低 PWRKEY，到 USB 可用，应等待 20s 以上
硬件关机：
- PWRKEY 管脚拉低 1.5s 以上时间，模块会执行关机动作。
- 关机过程中，模块需要注销网络，注销时间与当前网络状态有关，经测定用时约 2s~12s，因此建议延长 12s 后再进行断电或重启，以确保在完全断电之前让软件保存好重要数据。

3.1 Overview
鉴于其上电需要按开关开机的特性，外部必须加一个 MCU：
- 检测电池电压，10 min 持续的 < 3.2V，关机。10 min 持续的 > 3.3V，开机
- 作为 LTE Cat1 模组系统的外部看门狗，系统异常需重启
- 定时重启
- 备用系统：切换为 AT 模式
需给 Linux Core 留有接口：
- LoRa (SPI)
- LTE Cat 1 (USB)
- UART ---> MODBUS
TF 卡 + 文件系统
电源：
- SX1278: 1.8 ~ 3.7V
- SX1268: 1.8 ~ 3.7V (3.9 max)
- ASR6500: 1.8 ~ 3.7V
- Air724: 3.3 ~ 4.3V，至少 2A 电流能力。IO 电压 1.8V
