CE Notes European Union¶
The devices described in this manual may only be used in mobile or stationary systems in which the distance between antennas and persons is at least 20 cm.
Antennas may only be operated in conjunction with other antennas or transmitters if the required separation distance is maintained.
Changes or modifications to this device not expressly approved by the manufacturer can void the user's authority to operate the device under CE rules.
Antenna Requirements (Cellular)¶
The maximum antenna gain (including cable and connector loss) must not exceed the following limits for the supported frequency bands.

- B7: 11.96
- B8: 8.46
- B20: 8.23
- B28: 7.49
- B34: 11.96
- B38: 11.96
- B40: 11.96
- B41: 11.96
Antenna Requirements (Wi-Fi / BLE)¶
The maximum antenna gain (including cable and connector loss) must not exceed the following limits for the supported wireless interfaces.
Wireless Interfaces (dBi):
- BLE: 3.3
- WiFi 2.4 GHz: 3.3
- WiFi 5 GHz: 4.4
