摘要： Techniques are provided for selecting one of a plurality of clock signals used to drive a bus of a WLAN-enabled device having a WLAN radio module coupled to the bus and designed to operate over a plurality of WLAN channels. A network infrastructure device, such as an access point or port, is provided that comprises a WLAN radio module, a PCI bus coupled to the WLAN radio module, a look up table (LUT) and a processor. The WLAN radio module designed to operate over a plurality of WLAN channels in a first frequency band. The LUT comprises a plurality of entries. Each entry comprises: a particular one of the WLAN channels and a corresponding one of a first clock signal having a first clock frequency and a second clock signal having a second clock frequency that is to be selected. The first clock signal causes interference at the WLAN radio module when operating over a first subset of the WLAN channels, and the second clock signal causes interference at the WLAN radio module when operating over a second subset of the WLAN channels. The processor selects, from the LUT based on the one of the WLAN channels that has been selected for the WLAN radio module to communicate over, either the first clock signal or the second clock signal that is to be used to drive the bus.

摘要翻译： 技术被提供用于选择多个时钟信号中的一个，用于驱动具有耦合到该总线并设计成在多个WLAN信道上操作的WLAN无线电模块的具有WLAN功能的设备的总线。 提供了诸如接入点或端口的网络基础设施设备，其包括WLAN无线电模块，耦合到WLAN无线电模块的PCI总线，查找表（LUT）和处理器。 WLAN无线电模块被设计为在第一频带中的多个WLAN信道上操作。 LUT包括多个条目。 每个条目包括：WLAN信道中的特定一个以及具有第一时钟频率的第一时钟信号和具有要选择的第二时钟频率的第二时钟信号的对应的一个。 当在WLAN信道的第一子集上操作时，第一时钟信号在WLAN无线电模块处引起干扰，并且当在WLAN信道的第二子集上操作时，第二时钟信号在WLAN无线电模块处引起干扰。 处理器根据已经为WLAN无线电模块选择的WLAN信道之一从LUT中选择要用于驱动总线的第一时钟信号或第二时钟信号。

摘要： Described is a modular access point for wireless communications. The access point includes a housing which has at least one module receiving slot and a first wireless communication radio. The radio communicates with a first wireless device via a first frequency band. The access point also includes a removable module configured for insertion into the module receiving slot. The module includes a second communication radio utilizing a second frequency band so that, when the removable module is inserted into the slot, the access point is capable of communicating with a second wireless device via at least one of the first and second frequency bands. The access point includes a plurality of antenna connectors which are connected to the first and second radios. The access point may utilize external antennas or internal antenna modules which interchangeably attachable to the antenna connectors.
