Venture Wire reports that “In a bid to improve its in-house 802.11 capabilities, chipmaker Texas Instruments said it will acquire Radia Communications , a fabless semiconductor firm based in Sunnyvale, Calif. that specializes in Wi-Fi radios.” UnStrung adds that TI has made the buy to help with the development of silicon that supports multiple 802.11 radio standards on a single chip. Earlier TI had bought another little start-up, Alantro for $300 million in stock in June 2000. Ironically the announcement from TI comes close on the heels of Intersil’s decision to get out of the high volume but low margin WiFi chip business. Intersil was under pressure from Intel and Broadcom, two master of high volume chip business.
