International Embedded Exhibition T, And Newly Released Wi Fi 6 Supporting IC

Recently, in the wireless connection series of TI (Texas Instruments), there are two new products classified as "MCU or MPU attach", CC3300 and CC3301, which support the latest Wi-Fi 6. TI also exhibited this series of chips at the recent Shanghai International embedded Exhibition.

At the media meeting, Shi Ying, technical support director of TI in China, called the two chips companion IC (matching IC). They were mainly connected to this series of chips through SDIO/SPI or UART. "with a single antenna, the existing transmission system can be connected to the Internet of things through Wi-Fi or BLE."

Why Wi-Fi 6 is needed?
The two newly released SimpleLink series Wi-Fi 6 connection chips are not a relatively complete MCU like most of the previous CC series wireless connection chips. Shi Ying said: "We found that basically all the current electronic systems have very powerful processors or MCU." "We want to help customers think about how to quickly connect existing systems to wireless networks. So CC3300 and CC3301 made companion IC. "

Compared with Wi-Fi 5, Wi-Fi 6 implements up-and-down bidirectional MU-MIMO (multi-user, multi-input and multi-output) on this feature, which can cooperate with the aforementioned OFDMA. BSS Coloring (basic Service set Coloring) is a co-frequency transmission identification mechanism, which colours the data from different BSS, and the receiver can identify the same-frequency transmission interference signal and stop receiving it in the early stage, which improves the work efficiency for dense networks.
