The Laird SSD45N radio module which supports IEEE 802.11a/b/g/n standards via an SDIO (Secure Digital Input/Output) interface. The radio operates in unlicensed portions of the 2.4 GHz and 5 GHz radio frequency spectrum. The device is compliant with IEEE 802.11a, 802.11b, 802.11g, and 802.11n standards using Direct Sequence Spread Spectrum (DSSS) and Orthogonal Frequency Division Multiplexing (OFDM). The device supports all 802.11a, 802.11b, 802.11g, and 802.11n data rates and automatically adjusts data rates and operational modes based on various environmental factors.
When operating on channels in the UNII-2 and UNII-2 Extended bands that are in the 5GHz portion of the frequency spectrum and are subject to Dynamic Frequency Selection requirements, the SSD45N fully conforms to applicable regulatory requirements. In the event that specified types of radar are detected by the network infrastructure, the SSD45N fully conforms to commands from the infrastructure for radar avoidance.
The SSD45N is a System in Package (SiP) Quad Flat pack, No leads (QFN) module. The device is based on the Qualcomm Atheros AR6003X chip which is an integrated device providing a Media Access Controller (MAC), a Physical Layer Controller (baseband or BB processor), and fully integrated dual-band radio transceiver. To maximize operational range, the SSD45N incorporates external 2.4 and 5 GHz power amplifiers (PA) to increase transmit power. The frequency stability for both 2.4 GHz (802.11b and 802.11g) and 5 GHz (802.11a) operation is +/- 20 ppm. The SSD45N has its own RF shielding and does not require shielding provided by the host device into which it is installed in order to maintain compliance with applicable regulatory standards. As such, the device may be tested in a standalone configuration via an extender card.
The device buffers all data inputs so that it will comply with all applicable regulations even in the presence of over-modulated input from the host device. Similarly, the SSD45N incorporates power regulation to comply with all applicable regulations even when receiving excess power from the host device.
The SSD45N combines the 2.4 and 5 GHz signal path to signal U.FL type antenna connectors to support dual band transmission and receive. An antenna diversity function is NOT supported in this product. Supported host device antenna types include dipole and monopole antennas.
Regulatory operational requirements are included with this document and may be incorporated into the operating manual of any device into which the SSD45N is installed. The SSD45N is designed for installation into mobile devices such as vehicle mount data terminals (which typically operate at distances greater than 20 cm from the human body) and portable devices such as handheld data terminals (which typically operate at distances less than 20 cm from the human body).
