Broadcom has faced tough competition in the baseband market from Qualcomm (64% 2013 share, per Strategy Analytics), as well as MediaTek and Spreadtrum, who have been growing quickly in the low-end and mid-range segments with the help of aggressive pricing. The company partly blamed its weak Q4 guidance on baseband softness.
The Linley Group offered a mixed review for the M320, stating it "combines a leading-edge LTE baseband with a mediocre application processor." Qualcomm has dominated the 4G baseband market to date with the help of solutions that combine powerful app processors with advanced modems.
Nonetheless, Samsung has designed the M320, aimed at sub-$300 phones, into its mid-range Galaxy Core LTE phone. JPMorgan reported in December Broadcom had scored 4G baseband wins with Samsung and another top OEM.
