Semtech 推出用于全双工网关应用的 LoRa® Corecell 参考设计，使 LoRaWAN® 网关能够同时接收和传输数据
新 LoRa Core™ 产品提高了 LoRaWAN 网络通信效率，并减少了终端器件运营管理的时间和成本
加利福尼亚州卡马里奥 2021 年 4 月 28 日 – Semtech Corporation（纳斯达克股票代码：SMTC）是行业领先的供应商，提供高性能模拟和混合信号半导体产品以及先进算法。公司今天宣布在其 LoRa Core™ 产品组合中推出一款新产品，即适用于美国 902 - 928 MHz ISM 频段中全双工网关应用的 LoRa® Corecell 参考设计。新的统包网关解决方案可扩展室外和室内应用的网络容量，如智能计量、智能建筑和智能工厂。此外，参考设计使网络所有者可以在部署更少网关的同时增加网络容量，比蜂窝替代方案更省钱。
This full duplex design improves LoRaWAN® protocol message response time for applications requiring fast acknowledgement from the gateway, enables Firmware Update Over-The-Air (FUOTA) while processing uplink traffic and reduces the time and cost of operational management of end devices. Full duplex gateways support simultaneous transmit and receive of data, lengthening the downlink window to enable gateways to send more data to end devices and removing the latency experienced with half duplex gateways.
Semtech 无线和传感产品事业部物联网产品营销与战略副总裁 Marc Pegulu 表示：“Semtech 最早于 2020 年 8 月推出了针对中国 470 - 510MHz ISM 频段全双工网关应用 (SX1302) 的 LoRa Corecell 参考设计。借助此新产品，网关制造商还可以利用 Semtech 的全面参考设计为美国客户生产全双工网关。作为 LoRa Core 产品组合中的重要解决方案，Semtech 用于全双工网关应用的 LoRa Corecell 参考设计可提高 LoRaWAN 网络通信效率，同时扩大 LoRa 的覆盖范围和连通性。”
适用于全双工网关应用的 LoRa Corecell 参考设计的功能包括：
- Full duplex mode
- 与传统产品相比，功耗降低了 10 倍
- Transmit power (US915) up to +27dBm
- Receive sensitivity (US915) down to:
