85 | Say N. This should only be enabled on systems undergoing |
86 | certification testing and evaluation in a controlled environment. | |
87 | Enabling this will only enable TX99 support, all other modes of | |
88 | operation will be disabled. | |
89 | ||
90 | TX99 support enables Specific Absorption Rate (SAR) testing. | |
91 | SAR is the unit of measurement for the amount of radio frequency(RF) | |
92 | absorbed by the body when using a wireless device. The RF exposure | |
93 | limits used are expressed in the terms of SAR, which is a measure | |
94 | of the electric and magnetic field strength and power density for | |
95 | transmitters operating at frequencies from 300 kHz to 100 GHz. | |
96 | Regulatory bodies around the world require that wireless device | |
97 | be evaluated to meet the RF exposure limits set forth in the | |
98 | governmental SAR regulations. | |

105 | This option enables DFS support for initiating radiation on |
106 | ath9k. There is no way to dynamically detect if a card was DFS | |
107 | certified and as such this is left as a build time option. This | |
108 | option should only be enabled by system integrators that can | |
109 | guarantee that all the platforms that their kernel will run on | |
110 | have obtained appropriate regulatory body certification for a | |
111 | respective Atheros card by using ath9k on the target shipping | |
112 | platforms. | |
113 | ||
114 | This is currently only a placeholder for future DFS support, | |
115 | as DFS support requires more components that still need to be | |
116 | developed. At this point enabling this option won't do anything | |
117 | except increase code size. | |
