CDBAIRUI LoRa Modul 900 MHz USB-Schnittstelle E22-900T22U 22dBm Langstrecke 5KM DIP Drahtloses Modul mit Antenne RSSI LBT

Produktbeschreibung

Vollständig verbesserte Leistung, wir sind die ersten, die ein drahtloses Modul auf auf den Markt bringen. Höhere Effizienz, kleinere Größe, längere Entfernungen, schnelle Geschwindigkeit. Die hohe Übertragungsrate über die Luft kompensiert die langsame Geschwindigkeit herkömmlicher LoRa-Module. Remote-Konfiguration: Diese Funktion ermöglicht eine Fernänderung der Modulparameter, wodurch Installations- und Inbetriebnahmekosten und Wartungskosten effektiv reduziert werden. Hardware Interface Description:USB standard interface;Tactile switch;Two color display;SMA antenna connector;Package Content:1 x E22-900T22U and 1 x Stick Antenna;Long Range The transmission distance can reach up to 5000m (under ideal conditions), which is a significant increase compared to the transmission distance of ordinary logs Ra Ra modules with of the same performance. The transmission distance is significantly increased. compared to the transmission distance of a normal LoRa module of the same power. Automatic Trunking Network The modules can be used for multi-level relay networks suitable for ultra-long distances or complex environmental network communications and can run multiple networks simultaneously in the same area. Communication Key The user can set their own key and only the receiver module with the same key can receive the data, and the key cannot be read, improving the confidentiality of the user's data. Listen Before Talk (LBT) function - The module actively listens to the ambient noise of the channel before transmission and delays transmission when the noise exceeds the threshold; this function can improve the communication success rate of the module in harsh environments and can be used for group network transmission and anti-collision processing. RSSI signal strength, i.e. signal strength display function, the module supports serial output of the packet signal strength, which can be used to evaluate the signal quality, improve communication network, improve range; the module supports ambient noise signal strength serial output, which can be used to implement LBT function manually. Supports USB (serial) IAP online firmware upgrade;
