Isto devido ao fato da tecnologia fazer apenas a transmissão de dados, sendo que a voz continua sendo transportada pelo CDMA1xRTT, com isso além de liberar a tecnologia precedente para transportar livremente voz e ser totalmente compatível com o mesmo, ela permite transmitir uma alta capacidade de dados em uma única canalização de 1,25 MHz.
码片同步 ：指接收端的扩频码与发送端的扩频码在码片时序上的同步。这一过程需要解决码片时序的捕获和跟踪问题，通常采用滑动相关法、匹配滤波法等技术实现。
EV-DV can be an extension of cdma2000 1x that gives the voice services together with high-velocity data where by data rates can arrive at higher ranges than These with EVDO. EVDO has long been the popular data technological innovation for cdma2000 networks whereas EVDV is with a halt since 2005.
How can huge & cumbersome merchants provide Excellent shopper experiences that push ongoing loyalty at scale and without sacrificing margins? Ali Kamil, Expert Associate Husband or wife at McKinsey discusses what it's going to acquire to optimize last-mile operations for large and ponderous eCommerce.
