the maximum rate can reach 2Mbps.
11. RF Design Notes
11.1 Recommended RF Layout & Ground Plane
For EH-MC60, the integrated antenna needs a suitable reference ground plane to
improve radiation efficiency.
The area extending from under the antenna part of the module should be kept free of
copper and other metals. The module should be placed on the edge of the PCB with
the antenna edge facing outward.
