style="text-indent:25px">天線是移動通信系統(tǒng)中重要的組成部分，其質(zhì)量好壞對通信系統(tǒng)有直接的影響，**終影響手機的通信質(zhì)量和網(wǎng)絡(luò)的傳輸速度，基站在移動通信中的位置比較固定，用戶數(shù)量較大，所以正大信維通信天線認為，基站在選擇天線時應(yīng)該具備下述要求。 1、通信天線要有很高的增益。 2、天線的輻射方向應(yīng)覆蓋整個服務(wù)區(qū)域。 3、天線可在多個頻段工作，具有高帶寬。 4、天線與收發(fā)器之間要有良好的阻抗匹配。 5、通信天線的尺寸盡可能小，結(jié)構(gòu)盡可能緊湊。 6、天線多為線性偏振光，基站天線多為全向高增益天線。</p><p

智能WiFi天線怎樣改進無線網(wǎng)絡(luò)性能？企業(yè)的辦公場所是一個繁忙而經(jīng)常變化的環(huán)境，跟著職工的移動，Wi-Fi信號可能被障礙物遮擋。另外，WiFi信號還可能被周圍其它WiFi網(wǎng)絡(luò)信號或許職工的藍牙設(shè)備所攪擾，而平板電腦、筆記本、智能手機和其它WiFi設(shè)備在進入WiFi網(wǎng)絡(luò)范圍后的主動連接動作(就算這些設(shè)備并不需要真正運用Wi-Fi網(wǎng)絡(luò))，也會影響整個網(wǎng)絡(luò)的功能體驗。這一切攪擾的成果就是Wi-Fi網(wǎng)絡(luò)丟包嚴峻，導(dǎo)致無線設(shè)備有必要重新發(fā)送數(shù)據(jù)，而這又導(dǎo)致網(wǎng)絡(luò)進一步擁擠。因為不少移動設(shè)備的Wi-Fi天線功能都不夠強，因此經(jīng)常會選用一種較低的數(shù)據(jù)傳輸速率與接入點保持連接，企圖**小化丟包狀況。帶寬越大，問題越多因為網(wǎng)絡(luò)功能不良，并不是由帶寬缺乏引發(fā)的，因此一味加大網(wǎng)絡(luò)帶寬，并不能改善Wi-Fi網(wǎng)絡(luò)功能體驗欠安的狀況。而添加接入點也會讓狀況更糟糕，因為更多的接入點會形成更多的抵觸并讓無線終端設(shè)備感到困惑，不知道該與哪個接入點連接。其中一種解決方案是運用智能Wi-Fi設(shè)備接入點，同時運用特殊軟件支持的網(wǎng)絡(luò)硬件設(shè)備或針對繁忙網(wǎng)絡(luò)環(huán)境優(yōu)化過的網(wǎng)絡(luò)設(shè)備。平板天線結(jié)構(gòu)的揭秘如果我們將平板天線的天線面縱向切開的話，我們就會見到這個天線面是由五層結(jié)構(gòu)組成。莆田船用天線</p><p
