Abstract

In a 920-MHz band Internet-of-Things (IoT) platform via a low Earth orbit satellite, signal collisions frequently occur between the desired satellite IoT (S-IoT) terminals and interference from terrestrial IoT (T-IoT) terminals accommodated in the T-IoT platform. In this letter, computer simulation is used to evaluate the capacity for S-IoT terminals per satellite that can be achieved by applying minimum mean squared error receiver beamforming in each case of using low power wide area terminals of LoRa, Sigfox, and ELTRES. The results show that a satellite can accommodate 1 million-order terminals by using multiple channels in the 920-MHz band.
通过低地轨道卫星对 920-MHz 频段物联网平台的信道容量进行评估
在通过低地球轨道卫星的 920-MHz 频段物联网(IoT)平台中,所需的卫星物联网(S-IoT)终端与 T-IoT 平台中的地面物联网(T-IoT)终端之间经常会发生信号碰撞。在这封信中,计算机模拟评估了在使用 LoRa、Sigfox 和 ELTRES 的低功率广域终端的每种情况下,通过应用最小均方误差接收器波束成形,每颗卫星可实现的 S-IoT 终端容量。结果表明,通过使用 920 MHz 频段的多个信道,一颗卫星可容纳 100 万阶终端。
