5.4. Antenna Requirements

The following table shows the requirements on WCDMA, LTE, 5G NR antenna and GNSS antennas.
Table 35: Antenna Requirements
Type
WCDMA/LTE/5G NR
GNSS
NOTE
It is recommended to use a passive GNSS antenna when LTE B13 or B14 is supported, as the use of
active antenna may generate harmonics which will affect the GNSS performance.
