Abstract: Techniques to acquire the frequency of a signal instance based on a window of data samples covering a time period shorter than the time needed to achieve frequency lock. The window of data samples is initially captured and stored to a sample buffer. A segment of data samples is then retrieved from the sample buffer for processing. The retrieved data samples are rotated by a current frequency error estimate to provide frequency-translated data samples, which are further processed to provide one or more pilot symbols. An updated frequency error estimate for the frequency-translated data samples is then derived based on the pilot symbols using a frequency control loop. The window of data samples is processed for a number of iterations until frequency acquisition is achieved for the signal instance or termination is reached. For each iteration, one segment is processed at a time and typically in sequential order.

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.

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.

Abstract: When the user is actively transmitting/receiving or has recently transmitted/received on the RF channel, the user is referred to as being in an “active” state. Typically, if the user is in the active state, and neither sends nor receives data for a timer period greater than a threshold, then the user is transitioned off of the RF channel (e.g. transitioned from active to dormant). Once a transition to the dormant state has occurred, the continued transmission or re-transmission of data over an RF channel can result in a delay in re-accessing the RF channel. In order to address this problem, the idle-timer threshold is dynamically adjusted based on a communication system statistic to increase system performance.
