4G/LTE cellular baseband and RF is very hard to get right. Optimizing its power consumption for different scenarios is very very very hard to get right. The 4G graveyard is littered with companies that have tried and failed. TI. Agere. Infineon. Renseas (Nokia). Broadcom. Intel. All these have over time shut down their cellular baseband divisions. They've all released chipsets that work. But none have got the performance-power equation right. Phones built with their modems have all been battery drains that can't get you through the day if 4G is turned on. Qualcomm is the only supplier to consistently get this right.
