抗干扰能力 ：通过扩展信号频谱，减少了信号的能量密度，提高了信号对噪声和干扰的抵抗力。
Diverse carriers offer you diverse return choices. Although some carriers have more affordable return solutions, they may not have the most robust selections to account for every style of return. For example, USPS Firstclass Mail is really a baseline for affordably obtaining returned products less than sixteen ounces.

Unexpected emergency Services: EVDO played a job in supporting mobile data conversation for emergency services, enabling very first responders to access critical details and coordinate rescue endeavours in true time.
В явном виде отсутствует временное или частотное разделение каналов, каждый абонент постоянно использует всю ширину канала, передавая сигнал в общий частотный диапазон и принимая сигнал из общего частотного диапазона. При этом широкополосные каналы приёма и передачи находятся на разных частотных диапазонах и не мешают друг другу.
