2G Tracker是基于2G网络进行定位跟踪的设备或系统. 通常用于远程监控和跟踪人或货物的位置, 比如车辆追踪, 物流运输, 应急救援等领域.
2G Tracker通常由GPS模块组成, GSM模块和内置电池. 它通过接收GPS卫星信号获取位置信息, 并通过GSM网络将这些信息传输到指定的服务器或管理系统. 管理人员可以通过互联网或移动应用程序访问这些数据, 从而实时监控人或货物的位置和移动轨迹.
2G追踪器的主要优点是无需网络即可定位追踪. 它使用2G网络进行通信. 虽然网速慢, 它涵盖范围很广, 覆盖世界大部分地区. 此外, 2G追踪器价格相对较低, 因此广泛应用于低成本定位和跟踪应用.
然而, 2G网络也面临着逐渐淘汰的趋势, 因为世界正在转向更快、更高效的 3G 和 4G 网络. 所以, 未来可能需要更先进的跟踪技术来满足不断增长的需求.
