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

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。
