• Battery power for 5 years with 3 x 3.6V AA batteries
• Up to 5 km communication range in open space
• Longer communication range than 2.4GHz
• Better penetration through concrete and steel than 2.4GHz
• Less interference than 2.4GHz spectrum
• Application-ready I/O combination with modularization design
• WISE-4210無線傳感器節(jié)點(diǎn)和AP系列采用專有的LPWAN(低功耗廣域網(wǎng))無線通信技術(shù)。與傳統(tǒng)2.4G Wi-Fi相比，Sub-1GHz LPWAN可以優(yōu)化連接，消除網(wǎng)絡(luò)干擾。WISE-4210-S251節(jié)點(diǎn)具有可支持?jǐn)?shù)公里的通信距離和電池電量。使用3.6V AA鋰電池，傳感器節(jié)點(diǎn)可以在5公里的距離內(nèi)保持長(zhǎng)達(dá)5年時(shí)間的通信，從而消除了充電或更換電池的需要。
