style="text-indent:25px">無線通信模塊種類：在市面上常見的無線通信模塊分為以下幾種：1、無線數(shù)傳模塊，這種模塊廠家已經(jīng)做了單片機，并且寫好了無線通信部分的程序，可直接通過串口收發(fā)數(shù)據(jù)，使用簡單，當(dāng)相對來說成本也比較高。2、無線收發(fā)模塊，一般要通過單片機控制無線收發(fā)數(shù)據(jù)，一般為FSK、GFSK調(diào)制模式。3、ASK超外差模塊，主要用在簡單的遙控和數(shù)據(jù)傳送。無線通信模塊注意事項：1、合理的通訊速率。數(shù)據(jù)模塊的較大傳輸數(shù)據(jù)速率是9.6KBs，一般控制在2.5k左右，過高的數(shù)據(jù)速率會降低接收靈敏度及增大誤碼率甚至根本無法工作，湖州品牌3g無線通信模塊。2、合理的信息碼格式。單片機和模塊工作時，通常自己定義傳輸協(xié)議，不論用何種調(diào)制方式，所要傳遞的信息碼格式都很重要，湖州品牌3g無線通信模塊，它將直接影響到數(shù)據(jù)的可靠收發(fā)，湖州品牌3g無線通信模塊。代理

style="text-indent:25px">SIMcom無線通訊模塊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。一些人為了減少傳輸時間，把SIMcom無線通訊模塊的速率提升，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。天線是影響SIMcom無線通訊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。湖州品牌3g無線通信模塊無線傳輸模塊具有傳輸距離遠(yuǎn)，抗干擾性能強等優(yōu)勢。</p><div

style="text-indent:25px">為什么SIMcom無線通訊模塊的實際傳輸距離和廠家所說的距離會有出入。一些網(wǎng)上的客戶在購買了無線模塊之后，實際測量距離的時候，發(fā)現(xiàn)無線模塊實際傳輸距離和當(dāng)初購買時廠家所說的距離有些不太一樣，為什么會出現(xiàn)這樣的問題呢?1.兩個無線模塊之間有障礙物。廠商測量的時候一般環(huán)境都比較空曠，兩個無線模塊之間沒有障礙物，而客戶的使用環(huán)境一般很難達(dá)到這一點，基本上都有障礙物，因此實際距離會比較短些。2.電磁干擾信號。無線模塊廠家使用的環(huán)境比較純凈，很少有電磁干擾，而用戶使用的環(huán)境會有外界的干擾，使得數(shù)據(jù)傳輸出錯率上升，校驗不正常，宿短了距離。</p><p style="text-indent:25px">無線通信模塊的安裝則注重哪些要點呢？無線通信模塊的安裝注意事項：無線通信模塊的安裝要注意做防雷防水措施。雷雨天氣經(jīng)常遇到高壓大電流放電效應(yīng)，如果無裝備防雷保護的無線通信模塊則很容易受到雷電的影響，特別是需要架設(shè)天線的設(shè)備，一旦被雷電襲擊，通信線路將被中斷，高壓被引進(jìn)無線通信模塊系統(tǒng)后還會損壞內(nèi)部的控制電路，并會造成不可逆的破壞。因此，防雷防水措施則能在很大程度上保護無線通信模塊免受雷電襲擊，確保設(shè)備鏈路正常工作的有效措施。用代理
