INTEGRATION GUIDE 4. Software Integration 4.1. Radio Module Firmware Installation For reference, Linux OS information and device firmware information can be found in the following locations. GitHub - kvalo/ath10k-firmware: Firmware files for ath10k, a mac80211 driver for Qualcomm 802.11ac devices kernel/git/firmware/linux-firmware.git - Repository of firmware blobs for use with the Linux kernel 4.2. ath10k Driver Installation The RM-WIFI-AC-2X2-HP radio module operates in a Linux OS environment.
INTEGRATION GUIDE This can be verified by looking at the boot log or issuing the dmesg command and looking for lines that begin with ath10k_pci. The system needs to have the correct board data file at that location to pull the correct configuration and initialization information for the Radio Module to function. Below is an example of the driver and the PCTEL board data file loading correctly. root@OpenWrt:/# dmesg | grep ath10k [ 15.869293] ath10k_pci 0000:05:00.0: enabling device (0140 -> 0142) [ 15.

INTEGRATION GUIDE 5.2 Mechanical Implementation In order to deploy the RM-WIF-AC-2X2-HP-XX Radio Module in environments that will experience temperatures above 75 °C ambient, PCTEL requires that a properly sized thermal pad be installed between the bottom of the radio module and the host PCB. The thermal pad should cover most of the bottom of the Radio Module and be of appropriate thickness to fill in the gap between the Radio Module PCB and the host PCB as shown in Figure 4 and Figure 5 below. Figure 1.

INTEGRATION GUIDE Important Note: For use as a client device, (not DFS master), the integrator can choose or specify a different antenna of like type and equal or lesser gain as an antenna appearing in the above table and still maintain compliance. Reference FCC Part 15.204(c)(4) for further information on this topic. Important Note: For use in a host system that is a DFS master, the minimum, net antenna gain allowed is 1.1 dBi, including all other cable loss.
INTEGRATION GUIDE 6.1.3. FCC Radiation Exposure Statement This paragraph must be included in any end-user documentation. The PCTEL RM-WIFI-AC-2X2-HP-US has been evaluated for RF exposure for Humans in reference to ANSI C 95.1 (American National Standards Institute) limits. The evaluation was based on ANSI C 95.1 and FCC OET Bulletin 65C Rev 1.01. To comply with FCC’s RF radiation exposure requirements, the antennas used for this device must be installed such that the minimum separation distance of 7.
INTEGRATION GUIDE 5. The RM-WIFI-AC-2X2-HP-US radio module has been certified with the antennas listed in the table above. For use as a client device (DFS non-master), the integrator can choose or specify a different antenna of like type and equal or lesser gain as an antenna appearing in the above table and still maintain compliance. Reference FCC Part 15.204(c)(4) for further information on this topic. Note that the highest antenna gain used for approval is 7 dBi. 6.
INTEGRATION GUIDE To ensure regulatory compliance, when integrating the RM-WIFI-AC-2X2-HP-CA radio module into a host device, it is required to meet the documentation and operational requirements set forth by the applicable regulatory agency. The following sections outline the information that must be considered and included in the user’s guide and external labels for the host device that includes the RM-WIFI-AC-2X2-HP radio module. 6.2.1.
INTEGRATION GUIDE 6.2.2. ISED (Canada) Compliance Statement The following paragraphs must be included in any end-user documentation. This device contains license-exempt transmitters/receivers that comply with Innovation, Science and Economic Development Canada’s license-exempt RSSs. Operation is subject to the following two conditions: 1. This device may not cause interference. 2. This device must accept any interference, including interference that may cause undesired operation of the device.
INTEGRATION GUIDE 1. A module extends to the host manufacturer the ability to market an endproduct without the burden of filing a certification application for the RM-WIFI-AC-2X2-HP-CA, which has already been certified as a modular transmitter. It does not allow a host manufacturer or integrator the convenience to simply use the module without any further testing and evaluation. The combination of host + radio module must be evaluated for continued compliance in that specific configuration.
INTEGRATION GUIDE 10. Any end-user manual shall include all required regulatory information/warnings as shown in this manual. 11. Even though the PCTEL RM-WIFI-AC-2X2-HP-CA radio module has been ISED certified, the host product (i.e., the integrated product of radio module + host device) needs to be evaluated for continued compliance in that specific configuration. Contact PCTEL for any tools that may be required for such an evaluation. 12.
