Ụzọ Nile nke ụlọ usoro

Dị ka akụkụ nke a technology na-akp abụọ mmekọrịta ụzọ nke ụlọ usoro:

• jikọtara (ngwakọ);
• bi-directional (symmetrical).

Ke akpa (jikọtara) eji abụọ na ụdị ọwa:

• Ground (reverse) - arịrịọ maka nzukọ;
• satellite (kpọmkwem) - maka nnyefe nke ozi ka ọrụ.

Na nke abụọ usoro (bidirectional) ọmụma mgbanwe na-atụ na backward ntụziaka naanị satellite ọwa na-aka.

jikọtara usoro

Na jikọtara usoro iwu a terrestrial ọwa usoro - omenala. Onye ọrụ kọmputa na-ejikọrọ na obodo akụrụngwa na-eweta (ISP) ọrụ via a Wired modem njikọ ma ọ bụ site na cellular redio.
