Defects_TD2SCDMA_Standards
- 从智能天线的工作原理出发说明使用智能天线时很难实现小区的分扇区应用、多频点天线公 用,因此可以证明智能天线还不是一项可供商用的实用技术 考虑相邻小区/扇区时隙的不对称分 配所产生的相邻小区/扇区收发干扰时,可以证明上、下行时隙实质上是不能按需分配的。3 G使 用的频段是2 GHz,具有传播衰落大、穿透能力差、不易做大范围覆盖。TD2SCDMA标准很难提供3 G标准所规定的在车载、步行、静止环境下分别达到144 kbit/ s、384 kbit/ s和2 048 kbit/ s的无
IE8developer
- IE8正式版已经发布了。本篇文章不会非常扯蛋地去进行什么评测，然后给出什么“Chrome运行Javascr ipt能力是IE8的15倍”、什么“IE8页面渲染速度是Safari的2.456倍”、什么“IE8的抗强暴能力比FireFox高出1.235倍” 这样的操蛋的结论。我管谁比谁强多少？我只知道：当windows7发布的时候，IE8浏览器的市场占有率将让前台开发人员无法说：“不用去管IE8，没有几个人在用它”。所以，这篇文章将会非常务实的讲解一下，IE8中也许是唯一让开发人员感到亲切的“开发人
