Is Wifi hotspot really different form repeater?

Why can't a smartphone be used as a wifi repeater?

  • If it has an a/b/g/n wifi antenna, and can already be used as a hotspot broadcasting 3g and 4g signals, why can't it repeat an existing wifi signal and broadcast to other devices?

  • Answer:

    Because no company bothered to add this feature to the wlan stack. It can be done, but what would be the use case?
