Ekuhambeni kwethuba, ukusebenza kweefowuni kwavumeleka ukuba kuxhunyaniswe kwezinye iifowuni. Kwinkulungwane yama-20 iimatshini ezazisenza unxibelelwano zenziwa ukuba zizixhumanise ngokwazo.

Ngezo ntsuku abantu babesoloko bephethe aba ’’ndihamba naye’’ beefowuni, kwezinye izixeko okanye amazwe bekude kube yinto engaqhelekanga ukuhlala ungenayo. Ezinye iifowuni ezi lolu hlobo zinakho ukutsala umnxeba zisebenzisa i-satelite yonxibelelwano endaweni yeepali zonxibelelwano ezisemhlabeni, into ethetha okokuba abantu bangawutsala umnxeba nokokuba sele bephi na kwihlabathi jikelele.
