<p>一 a 对运营商的局站分布做适当了解,主要了解项目为局站开通容量,局站类型如无线接入站,光纤接如站等等.小区离局站的距离...</p><p>b 了解用户类型如学生,教师.工人.常驻人口,密集程度等等.一般来说商客类对数据业务需求较大,也比较容易沟通.</p><p>二 系统结构这个需要一定的专业知识.这里就不做太多说明了.你可以到网上搜一下ADSL的组成然后引深以下.ADSL接入商一般都是电信网通,设备可以选中兴和UT的.这个你要到厂商网站上看.一般小设备可以选9210 8426等等.</p><p>中继线路设计这个要根据实际居住小区的建设来规划.看有没有管道.或者架空电缆,或者无线传输或者小设备直接进小区,缆线初期布放按总户数的150%来算,可直接进楼道或者小区总配线架.</p><p>用户端需要设备为ADSL终端建议与设备同厂商.避免兼容性问题.软件现在运营商已经有了相关的专业软件.不需在做其他选择.(知识产权).</p><p>数据设置上问题不多.一般推荐做动态IP.也就是拨号上网.不建议做终端内置拨号.会产生许多垃圾信息早晨负荷增大.也不安全.而且容易卡在系统上.需手工清除.好了.其他的自己加点上去就OK了.</p>
