Metode Transmisi



Metode Transmisi
secara umum ada 3 metode transmisi, yaitu SIMPLEX, Half Duplex, dan  Full Duplex. Perhatikan gambar berikut :

Metode Transmisi Teknologi sinyal 2 G yaitu menggunakan Metode FULL DUPLEX.  Dalam komunikasi full-duplex, dua pihak yang saling berkomunikasi akan mengirimkan informasi dan menerima informasi dalam waktu yang sama, dan umumnya membutuhkan dua jalur komunikasi.
Komunikasi full-duplex juga dapat diraih dengan menggunakan teknik multiplexing, di mana sinyal yang berjalan dengan arah yang berbeda akan diletakkan pada slot waktu (time slot) yang berbeda. Kelemahan teknik ini adalah bahwa teknik ini memotong kecepatan transmisi yang mungkin menjadi setengahnya.
Sinyal 2 G dapat melakukan transmisi secara simultan, medium membawa  dalam waktu yang sama. Lihat gambar di bawah ini :
