Chapter 6 – Cellular Information
Antenna System Cellular Devices
The cellular/wireless performance depends on the implementation and antenna design. The integration of the
antenna system into the product is a critical part of the design process; therefore, it is essential to consider it early
so the performance is not compromised. If changes are made to the device's certified antenna system, then
recertification will be required by specific network carriers.
The antenna system is defined as the UFL connection point from the device to the specified cable specifications
and specified antenna specifications.
