Table 16, page 27 lists the Bluetooth RX Sensitivity.
6.4 Wi-Fi Antenna Requirements
Special care must be taken during the design of the RF section on the application board.
CAUTION! : If The below recommendation is strictly not followed then RF performance
degradation and infringements of emission limits will occur
A 50Ω antenna is required with Telit’s WE866E4-P module interface features an SMA
connector for an external antenna, alternatively a chip or a printed antenna can be used.
If an integrated or printed antenna is used, it is recommended to place it at the edge of the
application board. Since the antenna impedance is required to be tuned to 50Ω.
It is recommended to foresee a PI matching network between the WE866E4-P module and
the antenna during first prototyping. If not, a series 0Ω-resistor can be used, leaving the two
shunt components unpopulated.
To meet Telit’s FCC certification standard, the antenna on the application board should
have a gain value equal/less then the one recommended by Telit.
