Page 3 of 9 Revision History Revision Description of Changes Aug 2009 Initial Release Introduction This document describes mandatory steps required by the OEM integrator when designing and manufacturing any host PC system utilizing an Atheros radio module. Also refer to the Atheros Regulatory Compliance Guide available on the Atheros customer support site and from the Atheros customer support contact person. This document lists the mandatory responsibilities and actions of the OEM integrator. Failure to comply with all requirements and conditions in this document, may result in non-compliance of the host PC with FCC rules and invalidate the Atheros FCC certification for the module. This guide applies to Client modules that act under control of an Access Point. This document does not apply to a Client module or Access Point with radar detection feature. Allowed Antennas to be Used with the Radio Module The Integrator must request from Atheros sales or regulatory contact person the current list of allowable antennas for use with the specific radio module. This information is not available on the public FCC database but will be provided by Atheros. Atheros will provide a table of antenna type(s) models, cable lengths, and peak gain in each band. Generally, the list will include omnidirectional Inverted-F (PIFA) and stamped metal/film antennas for use inside laptops. In some cases, dipole antenna types may be included in the available list. Peak gain including cable losses are quoted in the table provided by Atheros. Use of any of the antennas in the list (identical or equivalent antenna with same gain, dimensions and cable lengths) is acceptable in the host device, without any further FCC testing or submission. However, use of an antenna that is Higher gain than those on the list or is a Different Type, requires additional testing and submission to the FCC. Also, if the host PC is certified as an FCC Portable device subject to RF Exposure (SAR) evaluation, then additional SAR testing per FCC rules may be required. Therefore, antennas with higher gain or different type than specified by Atheros, may not be used with the Atheros module until new testing and reporting is completed. You must contact the Atheros Regulatory Group to report any higher gain or new antenna type to be used with the module. Antenna Placement and RF Hazard (SAR) Compliance For host PCs certified as FCC Mobile Category devices, the FCC Grant of approval for the Atheros module is only valid when the Integrator ensures antenna placement in the host system that maintains at least 20 cm separation between any part of the antenna element(s) and any part of the end user’s body (considering their likely or usual operation position and grip). This spacing is naturally met by non-Mobile systems such as Access Points or Desktop PCs. Laptop PCs typically have integrated antennas placed high in the LCD display assembly. However, additional certification testing including RF Exposure (SAR) testing and an FCC certification submission are required to gain permission to place antennas closer than 20 cm to the end-user (e.g. a WLAN radio in a handheld personal organizer, Netbook or Tablet PC where the antennas will be close to the users hands or lap. Such host PCs will requi…
