As was the case at CES, Intel (INTC +0.3%) is unfurling a PR blitz at the Mobile World Congress. The company has officially announced its Clover Trail+ smartphone CPUs (previous). There are 3 dual-core chips in the family, with speeds ranging from 1.2GHz.-2GHz. Also unveiled is the XMM 7160 (.pdf), Intel's first LTE baseband modem with 2G/3G support. Intel says the chip, meant to challenge Qualcomm's (QCOM) 4G dominance, will ship in 1H, but Paul Otellini previously stated the first phones with an Intel LTE modem won't arrive until early 2014.
