style="text-indent:25px">無線發(fā)射模塊的抗干擾性能：它的主要優(yōu)點(diǎn)是它的抗干擾性能強(qiáng)。所謂抗干擾好,主要是指無線發(fā)射模塊在輸入信號噪聲比(簡稱信噪比S/N)相同的條件下,無線發(fā)射模塊調(diào)頻接收機(jī)輸出端的信噪比大于調(diào)幅接收機(jī)輸出端的信噪比。無線發(fā)射模塊采用的是聲表諧振器SAW穩(wěn)頻，無線發(fā)射模塊頻率穩(wěn)定度極高，具有極高性價比，無線發(fā)射模塊有完善的抗靜電保護(hù)，在行業(yè)中有相當(dāng)好的作用。用戶在選擇無線發(fā)射模塊時,一定要注意自己的產(chǎn)品是應(yīng)用于較復(fù)雜的環(huán)境,還是較簡單的環(huán)境,產(chǎn)品的使用壽命周期等。如產(chǎn)品要穩(wěn)定性和一致性好,都要選擇超外差無線發(fā)射模塊.如果用戶產(chǎn)品使用周期短,如遙控玩具,電單車報警等低價產(chǎn)品為了節(jié)約成本,可選擇超再生無線發(fā)射模塊。常州433mhz無線通訊模塊哪家好無線收發(fā)模塊整合了高頻鍵控收發(fā)電路的功能，以特小體積更低成本實(shí)現(xiàn)高速數(shù)據(jù)傳輸?shù)墓δ堋?/p><div

style="text-indent:25px">315M無線模塊和433M無線模塊的對比：315M的波長比433的長些，天線也比433的長些，方向性沒有433M的強(qiáng)，當(dāng)它的繞性好，315M的穿透能力比433M的弱些。433M無線模塊和2.4G無線模塊的對比：2.4G模塊型號傳輸距離短，(一般10~30米，確實(shí)通訊距離10米)，傳輸進(jìn)程衰減大，信號穿透、繞射能力弱，信號輕易被物體遮擋。433M無線模塊信號強(qiáng)，傳輸距離長、穿透、繞射能力強(qiáng)，傳輸進(jìn)程衰減減小。2.4G和433M是國內(nèi)免許可的ISM(工業(yè)、科學(xué)、醫(yī)學(xué))開放頻段，不需要向當(dāng)?shù)氐臒o線電管理申請授權(quán)，一般國內(nèi)常使用的是433MHz無線模塊。</p><p style="text-indent:25px">哪些因素影響無線發(fā)射模塊的傳輸距離以及怎樣提升傳輸距離?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433無線模塊的速率提升，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。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。一般常用的無線模塊要求的天線阻抗為50歐姆。</p><div
