iphone - How to check if device is LTE, 3G, HSPA or Wi-Fi?

Question

Is it possible to determine which kind of network is on the device when the user is interacting with my app?

Right now I have the Reachability class and I can differentiate between Wi-Fi and Cellular, but how to check if the Cellular is LTE, 3G, HSPA, EDGE?

Answer 1

目前没有办法区分不同类型的蜂窝网络。

Answer 2

从 iOS7 开始，可以使用 CTTelephonyNetworkInfo() 获得有关蜂窝连接的信息：

let info = CTTelephonyNetworkInfo()
print(“carrierName": " + "\(info.subscriberCellularProvider?.carrierName ?? "Has not been configured for carrier")")
print(“currentRadioAccessTechnology: " + "\(info.currentRadioAccessTechnology ?? "Airplane Mode/No cell connection")")

currentRadioAccessTechnology 将显示一个描述连接类型的字符串。
