產(chǎn)品簡(jiǎn)介
ME3612 是一款支持NB-IoT/eMTC/EGPRS通信標(biāo)準(zhǔn)的窄帶蜂窩物聯(lián)網(wǎng)通信模塊。在NB-IoT制式下,該模塊可以提供最大66 Kbps上行速率和34 Kbps下行速率,支持NB-IoT全球主流運(yùn)營(yíng)商頻段。該模塊與ME3630/ME3620/ME3610/MC8635/MW3650等LCC 30*30封裝系列的4G/3G模塊pin-to-pin完全兼容,用戶可根據(jù)不同的需求和場(chǎng)景進(jìn)行選擇,快速推出產(chǎn)品。
ME3612專為低速率、低功耗、遠(yuǎn)距離、海量連接的物聯(lián)網(wǎng)應(yīng)用而設(shè)計(jì)。該模塊支持多種網(wǎng)絡(luò)協(xié)議(PPP、CoAP、TCP/UDP、OMA LWM2M 、MQTT)和多種低功耗模式(PSM、eDRX)。這些協(xié)議和功能可以讓它應(yīng)用在智能表計(jì)、智能停車、資產(chǎn)追蹤和可穿戴設(shè)備等多種物聯(lián)網(wǎng)及M2M的應(yīng)用場(chǎng)景中。
