wifi - Mobile HotSpot:802.11 to Cellular data conversion -


i trying understand mobile hotspot technology (tethering). specifically, interested in how devices connected hotspot (via wi-fi) access internet via cellular network. here specific questions :

  1. i assuming internet access on cellular network (say 4g) accomplished through ipv4 or ipv6 packets. true?
  2. if 1 true, how 802.11 packets translated form ipv4 or ipv6 packets?
  3. if 1 false, frames used access internet on cellular networks? , how 802.11 frames translated form these packets (cellular data)?

i did read specification documents available ipv4, ipv6 , 802.11 not mention particular (wlan<->cellular data) conversion.

thanks!

further reading.

802.11 packets not translated ip packets, or vice versa. ip packets (layer 3) encapsulated in ethernet , 802.11 (layer 2, layer 1) packets.

it hard explain further until have basic grasp of network layers (which don't have @ moment).
