Тестирование дальности связи LoRa2021

LoRa2021 — это модуль беспроводного приемопередатчика, разработанный компанией G-NiceRF на базе новейшего чипа Semtech LoRa® LR2021 . Он не только сохраняет преимущества дальней связи LoRa, но и реализует переход от «низкоскоростных датчиков» к «высокоскоростной передаче». Типичное значение чувствительности приема LoRa2021 составляет -143 дБм (SF12/62,5 кГц). В диапазоне частот Sub-GHz чип LR2021 добавляет поддержку FLRC , при этом скорость передачи данных может достигать 2,6 Мбит/с (в стандартном режиме LoRa она составляет до 125 кбит/с). Значительное увеличение пропускной способности позволяет LoRa2021 поддерживать передачу изображений , отправку голосовых или аудиофрагментов, а также обновление пакетов данных большего объема. Кроме того, данный модуль охватывает широкий спектр частот. Он поддерживает популярные диапазоны Sub-GHz (стандартные 433/470/868/915 МГц, с возможностью настройки 150–960 МГц) и диапазон 2,4 ГГц ISM . Также он поддерживает высокие частоты 1,5–2,5 ГГц (включая спутниковую связь S-диапазона ), обеспечивая покрытие от земли до спутников. Это эффективно решает проблему связи в районах без покрытия общедоступных сетей и устраняет необходимость разработки разных версий оборудования для разных стран. Один и тот же продукт можно адаптировать к различным рынкам по всему миру с помощью программной настройки, что значительно снижает давление на складские запасы и расходы на разработку . При сохранении низкого энергопотребления с током в спящем режиме ≤2 мкА , LoRa2021 интегрирует технологию скачкообразной перестройки частоты LR-FHSS для работы в условиях сильных помех. Он также поддерживает измерение дальности RTToF и полностью совместим с основными протоколами Интернета вещей, такими как LoRaWAN , BLE 5.0 и Wi-SUN .
