Shareholders of Texas Instruments Inc. (TI), once the cellphone chip leader, want the company to reduce its money-losing investment in wireless or even exit the market, Reuters reported. TI, which makes chips for products as diverse as phones and cars, is already winding down its development of baseband chips that connect mobile phones to cellular networks. Now analysts want TI to take similar action with its two remaining wireless businesses: its OMAP application processors, which support mobile features like video and gaming, and its wireless connectivity chips.
