Integrated baseband puts forward higher requirements for the integration of SoC design, and also has advantages in the power consumption of communication data exchange. Relatively speaking, the external baseband will cost more, consume more power, and occupy more space inside the mobile phone-in Apple's style of always cherishing space as gold, the external baseband has probably always been a pain point for Apple.
Features of 5g:
1, the peak rate needs to meet the standard of GBIT/S, in order to meet the high-definition video, virtual reality and other big data transmission.
2. The air interface delay level needs to be around 1ms to meet the real-time applications such as automatic driving and telemedicine.
3. Ultra-large network capacity, providing the connection capability of hundreds of billions of devices to meet the communication of the Internet of Things.
4. The spectrum efficiency is 10 times higher than that of LTE.
5. With continuous wide-area coverage and high mobility, the user experience rate reaches100 mbit/s. ..
6. The flow density and connection density have been greatly improved.
7. It improves the level of collaboration and intelligence of the system, and has the characteristics of multi-user, multi-point, multi-antenna and multi-portal collaborative networking, and flexible and automatic adjustment between networks.
