  • You need to transfer a file of known size from your server and measure how long it takes to get an estimate of network transfer speed. – Paulw11 Mar 03 '20 at 06:53
  • Maybe you can use something like this -> https://stackoverflow.com/a/39954864/7512091 He created a function to download image from server and calculate elapsed time. – emrcftci Mar 03 '20 at 06:54
  • @Premkumar You need to check this link - https://developer.apple.com/documentation/networkextension/nehotspotnetwork/1618923-signalstrength – Ram Mar 03 '20 at 06:55
  • The signal strength won't tell you much about the actual transfer speed; It is rarely the WiFi signal on its own that determines transfer speed; – Paulw11 Mar 03 '20 at 07:19
