Narrow Band Internet 窄帶物聯(lián)網(wǎng)
Narrow Band Internet of Things, (NB-IoT) is a technology being standardized by the 3GPP standards body. This technology is a narrowband radio technology specially designed for the Internet of Things (IoT), hence its name. Special focus of this standard are on indoor coverage, low cost, long battery life and large number of devices. This technology can be deployed in GSM and LTE spectrum. 窄帶物聯(lián)網(wǎng)是由3GPP(《第三代伙伴計(jì)劃協(xié)議》)標(biāo)準(zhǔn)化組織定義的一種技術(shù)標(biāo)準(zhǔn),是一種專為物聯(lián)網(wǎng)設(shè)計(jì)的窄帶射頻技術(shù),因此得名。以室內(nèi)覆蓋、低成本、低功耗和廣連接為特點(diǎn)。這種技術(shù)可應(yīng)用于GSM網(wǎng)絡(luò)和LTE網(wǎng)絡(luò)。 和窄帶網(wǎng)絡(luò)對應(yīng)的則是寬帶網(wǎng)絡(luò)(Broadband network),一般指的是帶寬超過155kbps以上的網(wǎng)絡(luò)。【Narrow Band Internet 窄帶物聯(lián)網(wǎng)】相關(guān)文章:
