1. A method for determining a deployment configuration of a radio frequency device including a plurality of switchable radio frequency elements disposed on a surface, the method comprising:
configuring the radio frequency device according to a plurality of different configurations including, for each configuration of the plurality of different configurations, switching respective states of multiple switchable radio frequency elements of the plurality of switchable radio frequency elements as specified by said configuration of the plurality of different configurations;
receiving, for each configuration of the plurality of different configurations, feedback characterizing a quality of a transmitted signal received at one or more receivers; and
determining, based on the feedback for each configuration of the plurality of different configurations, the deployment configuration of the radio frequency device including determining a deployment state for one or more switchable radio frequency elements of the plurality of switchable radio frequency elements,
wherein the determining of the deployment configuration comprises performing, for each switchable radio frequency element of the multiple switchable radio frequency elements, a majority voting algorithm that determines the deployment state for said switchable radio frequency element by voting on the deployment state of said switchable radio frequency element based on the characterized quality of the transmitted signal.
