你好 , 我的平板型号是X98 air 3G , 最近升级了安卓4.4.4版本 , 怎么获取Root权限 , 试了好多软件了 ;

参考技术A 尊敬的台电用户，您好：
非必要的情况下不建议您root平板，root会导致系统不稳定的。
感谢您对台电的支持！ 参考技术B 你好！您可以使用“卓大师一键root”来获取ROOT，另外您也可以在recovery模式下手动刷入第三方的ROOT包来获取权限。一般的手机大部分也都是可以用ODIN来线刷特定的包来获取权限的，相关的教程您可以在论坛上搜一下。

用ROOT大师可以一键ROOT
步骤一：打开ROOT大师，用数据线将手机连接电脑，等待电脑安装手机驱动，然后ROOT 大师就能识别到你的手机型号；
步骤二：点击一键ROOT，按照提示一步步进行操作，会提示你成功ROOT。
祝你成功获取ROOT权限！

Cisco AP-Regulatory Domain

这一note主要解释Regulatory Domain是什么。以较新的思科AP的型号举例，思科AP的PID一般都是按照如下的命名：

AIR-AP3802I-H-K9C

按照自己的理解：

AIR：其中的相关信息都比较好理解，Aironet无线产品一般都是AIR开头的，例如无线AP都是AIR-... ，无线WLC也是AIR-....

AP：AP自然不用多说，代表AP（Access Point）；

3802：代表AP的具体型号和系列，例如同系列的还有1810,1832,1852,2802,4800(4800是目前最新的AP）

H：代表的就是Regulatory Domain，这个和国家有关，因为不同的国家，允许的无线频段不一样，例如我们国家，-H就代表China，当然-C也可以在中国使用，因为-C的无线频段也符合国家的允许。其实这个-H参数根本上代表的就是无线信道使用的频段。

C (C regulatory domain):

●  2.412 to 2.472 GHz; 13 channels

●  5.745 to 5.825 GHz; 5 channels

K9：代表加密，这个和路由器中的K9应该差不多，K9 Product bundels have strong AES/3DES encryption.

C：代表Configurable，对于该类型号的AP，带C代表出厂时ME（Mobility Express）镜像的，如果不带C，出厂的镜像应该是LAP的镜像。
