1. Introduction The purpose of this document is to provide the usage of the applications for transmit and receive tests to evaluate the RF performance of the ALXC28 using a test driver in Linux environment.The evaluation board provides the necessary connectors so that you can measure transmit and receive performance of the PHY, using Spectrum Analyzer and Signal Generator in either 2.4GHz or 5GHz (For ALXC28 module). In general, transmit performance of a radio can be analyzed in three steps.
Figure 1: Linux Based RF Evaluation Setup With RJ45 Interface Following diagram illustrates various software components involved in performing Tx and Rx tests using spectrum analyzer and signal generator respectively. The ‘transmit’ utility is a command line application to perform Tx tests. Before running the Tx tests, the user is expected to connect ALXC28 moudle to a signal analyzer using the RF cable.
3.1 Tx Application Usage The application can be started in the following steps: plug RJ45 cable into the device and labtop, set the labtop’s ip and the ip of device in the same network segment, and then Login to the device, send the command via labtop cmd window. # cd /etc/wifi # sh ./bcmdhd_active.

FCC Declaration This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference. (2) This device must accept any interference received, including interference that may cause undesired operation. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1) This device may not cause harmful interferences, and (2) this device must accept any interference received, including interference that may cause undesired operation.” The module is limited to installation in mobile or fixed applications. Separate approval is required for all other operating configurations, including portable configuration with respect to Part 2.1093 and different antenna configurations.
The requirement for KDB 996369 D03: List of applicable FCC rules FCC CFR Title 47 Part 15 Subpart C Section 15.247, Part 15 Subpart E Section 15.407 Summarize the specific operational use conditons This module has been granted Single Modular Approval for mobile applications. OEM integrators for host products may use the module in their final products without additional FCC certifications if they meet the following conditions. Otherwise, additional FCC approvals must be obtained.
Picture 2 RF exposure considerations The host device manufacturer should confirm that a separation distance of 20cm or more should be maintained between the antenna of this host device and persons during the host device operation.
The device itself has antenna, customer can use the PIFA antenna with antenna gain isn't greater than 5 dBi.
