Module Placement
The placement of the module in the base board is critical in your design. Improper placement can lead to poor antenna performance. BDE recommends following below practical placement to achieve expected antenna performance.
Any form of proximity to the metal or other material will change/degrade the antenna performance. Keep the antenna area as far as possible to the metal material in any direction. If metal materials cannot be avoided in your design for example the design with metal enclosure, we recommend keep the antenna area at least 40mm distance to the enclosure in all directions. Customers should verify the communication range with the mock-up or real product prototype on their own.
