NB-IoT模組布局物聯網先機

2019-11-28 視點

NB-IoT最大的特點,是傳輸距離達到驚人的10km,可以覆蓋一個小縣城。而且可以帶無數終端,一個基站可以帶20多萬個終端。這意味著,管理一個井蓋、停車收費,都變得輕松,而且便宜。即使是200萬元建立一個基站,十平方公里都可以進行管理。

從技術層面看,5G有三個標準,分別是LTE(授權頻道)、LTE-U(非授權頻道)和NB-IoT(授權頻道)。LTE,屬于授權頻道,這是最大的商業價值,誘惑力很大。由于授權頻道基本是排它的,是運營商的壟斷資源,只能通過運營商來操作。LTE-U非授權頻道,通訊距離可以達到500米左右(類似3G時代曾經推過的“城域網”)。ISM(工業、科學、醫療)這三個領域可以隨便用,主要頻段包括從5K、13.56M一直到2.4G和5.8G等多個頻段。而NB-IoT(由于NB-IoT屬于授權頻道,仍然不太可能在企業里用。所以NB-IoT也只能是先接入核心網,即運營商,再進入企業)。NB-IoT皇冠正规赌城赌场最大的特點,是傳輸距離達到驚人的10km,可以覆蓋一個小縣城。而且可以帶無數終端,一個基站可以帶20多萬個終端。這意味著,管理一個井蓋、停車收費,都變得輕松,而且便宜。即使是200萬元建立一個基站,十平方公里都可以進行管理。
