Представлены форматы транспортных блоков, обсуждаются особенности передачи трафика вниз и вверх. Дана оценка пропускной способности каналов передачи трафика NB-IoT.</p></abstract><trans-abstract xml:lang="en"><p>On the basis of LTE specifications (Releases 13–15) NB–IoT technology physical level channels and signals are considered, including synchronization signals and preamble for random access procedure.
