How is it different from the orignal SX-SDMAC?

This new design is optimized for cost, size and performance that makes it a very compelling option for customers who want to take advantage of the higher 802.11ac performance at a lower cost and smaller overall footprint. 

It is optimized for both size and cost by redesigning the PCB, removing the RF switch and the additional antenna connector available on our other SX-SDMAC SKU’s. Also by using an Xtal crystal oscillator instead of TCXO, the SX-SDMAC-Plus offers higher Tx power which results in better Wi-Fi coverage and performance.
