style="text-indent:25px">無線通信是利用電磁波信號在自由空間中傳播的特性進(jìn)行信息交換的一種通信方式。無線通信技術(shù)自身有很多優(yōu)點(diǎn)，成本較低，無線通信技術(shù)不必建立物理線路，更不用大量的人力去鋪設(shè)電纜，而且無線通信技術(shù)不受工業(yè)環(huán)境的限制，對抗環(huán)境的變化能力較強(qiáng)，故障診斷也較為容易，相對于傳統(tǒng)的有線通信的設(shè)置與維修，無線網(wǎng)絡(luò)的維修可以通過遠(yuǎn)程診斷完成，更加便捷;擴(kuò)展性強(qiáng)，當(dāng)網(wǎng)絡(luò)需要擴(kuò)展時，無線通信不需要擴(kuò)展布線;靈活性強(qiáng)，無線網(wǎng)絡(luò)不受環(huán)境地形等限制，而且在使用環(huán)境發(fā)生變化時，無線網(wǎng)絡(luò)只需要做很少的調(diào)整，就能適應(yīng)新環(huán)境的要求。</p><p style="text-indent:25px">無線模塊傳輸距離的影響:1、廠商產(chǎn)品介紹的傳輸距離，是在環(huán)境較好的空曠地嘗試的較準(zhǔn)確的數(shù)據(jù)，客戶買回來使用的環(huán)境干擾比較多，比如樓房墻壁、樹木等。提升傳輸距離的方法：傳輸距離不夠長的時候，可以挑選一些障礙物較少的地方使用，以此達(dá)到增加距離的目的。2、電源在使用一段時間后，電壓會減少，導(dǎo)致傳輸距離減少。要想提升傳輸距離，可以更換一個電容量大電壓穩(wěn)定的電源。3、一些人為了減少傳輸時間，把無線模塊的速率提升，會導(dǎo)致傳輸距離減少。所以使用的時候可以把傳輸速率調(diào)低一些，這樣可以增加無線模塊傳輸距離。4、天線是影響模塊傳輸距離的因素之一，高增益天線可以讓距離傳輸更遠(yuǎn)，另外提升天線的架設(shè)高度，盡量保持天線離地面2米以上，這樣可以達(dá)到較好的傳輸距離。所有物聯(lián)網(wǎng)感知層終端產(chǎn)生的設(shè)備數(shù)據(jù)都需要通過無線通信模塊匯聚至網(wǎng)絡(luò)層。</p><div
