Технология LTE что это – в чем отличие от 3G и 4G сетей

Разберёмся что такое LTE в смартфоне, и чем оно отличается от привычного 3G. Какие технологии передачи данных предлагают сети четвёртого поколения, и что это даст пользователям?

Что такое LTE

Многие смартфоны поддерживают LTE, но пока не всем пользователям известно, что это значит.

Стандарт является промежуточным этапом в переходе от 3G к 4G. Подключение к такой сети значительно увеличивает скорость передачи данных как загрузки, так и выгрузки. Но несмотря на это, он не дотягивает до технических характеристик, принятых для очередного четвёртого поколения связи.

Технология передачи данных

Сеть нового поколения предоставляет возможность соединения на скорости до 100 Мбит/сек (теоретически максимальная скорость). В реальности она на порядок ниже, все равно технология значительно опережает предыдущий стандарт. В основе лежит пакетная передача данных MIMO, и система кодирования OFDM. Благодаря распределению передающих антенн корреляционная зависимость полностью исключена. В разных странах связь работает на различных диапазонах. Даже разные операторы связи внутри страны нередко используют различные частотные диапазоны.

Сравнение с 3G

Если сравнить два последних поколения сети, действующее и только развивающееся, то получатся следующие выводы:

• 4G обеспечивает передачу данных со скоростью в сотни раз выше предыдущего поколения;
• разная технология передачи данных, полностью пакетная в новой и коммутация каналов и пакетов в предыдущей;
• наличие VoIP в 4G;
• возможность интеграции с E-Ultra;
• стабильность связи даже при высоких скоростях перемещения объекта.
  

Все это несомненные превосходства новой сети. Но есть и недостатки, 3G за время своего существования может похвастаться обширной зоной покрытия. LTE сегодня присутствует только в ряде крупных городов страны.

LTE и 4G

Оба стандарта относятся к одному поколению, они имеют ряд отличий. Эти технологии нельзя считать одним и тем же.

В чём разница, у LTE по сравнению с 4G:

• более низкая скорость выгрузки данных;
• низкая пропускная способность (ЛТЕ – 150 Мб/с, 4G – до 1 Гб.);
• ниже скорость приёма.

Плюсы использования в телефонах и планшетах

Какие преимущества для пользователей несёт внедрение новых стандартов связи?

• просмотр видео в высоком качестве без задержек;
• использование видеосвязь для звонков и для видеоконференций;
• эффективное использование в качестве роутера для раздачи WiFi.

Увеличение скорости передачи данных способствует расширению услуг и снижению их стоимости.

Какие операторы предоставляют в России

Все ведущие компании предоставляют абонентам такую возможность. Также операторы снабжают пользователей модемами и карманными роутерами, для доступа в сеть.

• Мегафон имеет широкую зону покрытия, но более высокую стоимость услуг в отличие от конкурентов. Предлагает до 40 Гб ежемесячно, для доступа к интернету через LTE подключается отдельная опция.
• МТС имеет меньшую зону покрытия. Абонентская плата за услуги связи ниже чем у предыдущего конкурента, а объёмы ограничиваются 25 Гб.
• Билайн предоставляет специальную сим-карту с поддержкой LTE. Стоит отметить, что зона покрытия этого оператора шире, чем у МТС.
• Теле2 также внедряет LTE. Но пока доступ есть только в крупных городах.

Как подключиться к LTE

Если смартфон поддерживает LTE, то для подключения достаточно иметь правильно настроенную точку доступа. Как только гаджет окажется в зоне покрытия 4G, он автоматически переключится на высокоскоростную сеть.

Ряд моделей смартфонов отлично переключится на LTE, но как только покидают зону покрытия не могут самостоятельно вернуться к 3G. Они не видят сети, и чтобы вновь появилась возможность использования интернета необходимо перезагрузить устройство.
