<p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"> </p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"><p> </p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"><p> </p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;">一、规划网络前,需要实地测试。对于无线传输,影响其效果的因素很多,任何计算都比不上到现场实地测试准确。这是非常必要的,不要因为怕麻烦而最后事半功倍。 <p></p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"><p> </p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;">二、天线安装位置要距离设备最少20厘米。设备本身信号虽然很弱,但也有信号。怕会出现干扰。<p></p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"><p> </p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;">三、安装天线时,要关闭无线设备的电源,这是对设备的一种保护。<p></p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"><p> </p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;">四、当无线网络设备工作时,不要靠近天线。人近距离的在微波下会出现头晕,恶心的症状。<p></p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"><p> </p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;">五、如果是无线Roaming(漫游)模式,为了保证相邻AP覆盖的小区之间没有干扰,要求它们的信道间隔至少为25MHZ<p></p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;">六、天线馈线的阻抗要与天线的阻抗匹配。因为天线作为终端负载时,匹配能保证天线取得全部信号功率。<p></p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"><p> </p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"> 七、天线馈线不宜过长。信号在馈线中传输,除有导体的电阻性损耗外,还有绝缘材料的介质损耗。这两种损耗随着馈线长度的增加和工作频率的提高而增加。因此,应合理布局缩短馈线长度。<p></p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"><p> </p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"> 九、天线馈线切忌不要和强电流的线路并行走向,也不能靠近低频信号线路。因为同轴电缆工作频率范围宽,损耗小,对耦合电路有一定的屏蔽作用,但对磁场的干扰却无能为力。<p></p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"><p> </p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"> 十、施工过程中,天线一定要小心轻放。因为里面的天线馈元很脆弱。<p></p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"><p> </p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"> 十一、室外工程避雷针一定不能省。<p></p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"><p> </p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"> 十二、无论无线工程中无线设备是什么品牌,其有线部分都要用最佳的线缆、水晶头和布线部件。<p></p></span></p><p class="MsoNormal" align="left" style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-layout-grid-align: none;"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 宋体; mso-font-kerning: 0pt; mso-ansi-language: ZH-CN;"> 线缆仍是网络的基础,一旦有线部分不能运行,根本就谈不上其它的东西。<p></p></span></p> |
