It applies multicarrier modulation methods to 3G networks. This offers larger data rate, higher bandwidth and better voice high-quality. It is additionally backward compatible with more mature CDMA variations.
EOP is indicated because of the transmitter driving two bit situations of SE0 (D+ and D− both equally underneath max.) and 1 little bit time of J state. After this, the transmitter ceases to travel the D+/D− lines and also the aforementioned pull-up resistors maintain it within the J (idle) point out.
