Following a shock move to acquire security vendor McAfee earlier this month, Intel today announced an altogether more expected move, purchasing Infineon’s Wireless Solutions Business for a reported $1.4 billion in cash. The acquision, heavily rumoured over the weekend, enhances Intel’s presence in the booming mobile device market, adding 3G capabilities to the company’s existing Wi-Fi and 4G WiMAX offerings across smartphones, tablets, netbooks, notebooks and embedded computing devices.
