Abstract
In an RF access control system, a method for establishing a reliable RF signal link between points of the RF access control system. A first RF signal from a first point of the system is transmitted to a second point of the system at a first RF power level that is below a second RF power level used during normal operation of the RF access control system. Once the second point acknowledges the RF signal from the first point, then a pre-determined number of RF packets are transmitted and received back and forth between the first point and the second point at the first RF power level. An RF packet error count is generated in response to the transmitting and receiving of the pre-determined number of RF packets. If this error count is below a certain threshold value, then an indication is provided to an installer of the RF access control system of an RF channel number to be used by the RF access control system during normal operation.
