Iyo irekuye, ibimenyetso bihindura kwakira uburyo, byemeza ko ishyaka rimwe ryonyine rishobora kohereza kumuyoboro umwe icyarimwe. Byuzuye - uburyo bwa duplex butuma impande zombi zohereza no kwakira ubutumwa bwijwi icyarimwe, bisa no guhamagara kuri terefone igendanwa, ariko mubisanzwe bisaba ibikoresho byagutse kandi bikunze kuboneka muri sisitemu yabigize umwuga.
