КорзинаТестирование продуктов компании UBNT (NanoBridge M5, Bullet M5, Rocket M5)
В первую очередь нам хотелось бы протестировать новый стандарт MIMO и новый алгоритм AIRMax.
Все продукты одной компании UBNT поддерживают стандарт (N)-MIMO. Как заявляет производитель, скорость передачи данных может достигать 150Мб и даже 300Mб. Давайте посмотрим на реальные цифры непростого теста.
NanoBridge M5
Испытание между точками доступа. Они разнесены на расстоянии 285 метров. Тесты показали до 121Mbps Udp трафика, пропускная способность до (90 tcp и 31Mbps дуплекс).
Результаты тестов:

Скажу честно: все очень субъективно. Но на факторы тестирования оборудования сильно влияли помехи в эфире. Постоянно приходилось подбирать частоту, на которой меньше всего шума. Все продукты компании UBNT справились со своей задачей и могут применяться для построения дальнобойных - магистральных линков.
