General Description The 17WFM21 WI-FI module design is a highly integrated MIMO wireless LAN (WLAN) used for high speed wireless local network access. The card is built with 2T2R capable RF/baseband single chip. The 17WFM21 WI-FI module design implements multiple input, multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) with 2 transmit and 2 receive paths and is compatible with 802.11 a/b/g/n specifications. For legacy compatibility, direct sequence spread spectrum (DSSS), complementary code keying
(CCK) and OFDM baseband processing are included to support all 802.11b, and 802.11g data rates. Differential phase shift keying modulation schemes, DBPSK and DQPSK with data scrambling capability, are available along with complementary code keying to provide the data rates of 1, 2, 5.5 and 11Mbps with long or short preamble. The high speed FFT/IFFT paths, combined with BPSK, QPSK, 16QAM, and 64QAM modulation of the individual subcarriers and rate compatible punctured convolutional coding with coding rate of 1/2, 2/3, 3/4, and 5/6, provides the maximum data rate of 54 Mbps and 300 Mbps phy rate for IEEE 802.11g and 802.11n MIMO OFDM respectively. Module has no DFS (Dynamic Frequency Selection) and is only a DFS Client. 2.

Hardware & Software installation 11.1. Hardware Installation 17WFM21 module is a build in module. It will be used in-house production as an embedded device over USB 2.0 interface and there is no need any interaction with end-user. Positioning of the module is defined by assembly operator instructions for each product by Vestel. The recommended installation of 17WFM21 module is shown below. The WI-FI module should be mounted by considering operating temperature. The temperature of the installation location should be between 0C and 65 C. The module can be installed in mobile or fixed hosts. For portable devices a minimum separation distance of 45mm between the antenna and the human body shall be observed to avoid SAR requirements. The implementation of the module in a specific end-product should also be reviewed to ensure compliance with the FCC and IC requirements for SAR and MPE. 6 11.2 Software Installation The SW driver is already installed to host device software platform which is a Linux/Android OS. Proper country information must be selected from UI during first time boot up settings. Country information is used to disable (deactivate) channels/frequency ranges which are not allowed by country regulations. The host integrator must follow the integration instructions provided by Vestel and ensure that 12. FCC/IC Warning the composite-system end product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules and to KDB Publication 996369. visible on the back cover of the host device.
