Wireless network interfaces that are capable of transmitting and/or receiving beamformed radiofrequency (RF) signals may be assisted by the use of codebooks. Electronic devices with memory to store a database of codebooks may be used to increase the number of entries available for operation. The database of codebooks may employ environmental parameters to improve efficiency of the wireless network interface. Methods for calibration of electronic devices and/or adjustment and selection of codebooks based on the parameters are also described. The calibration may employ a testing chamber that measure powers at in a limited number of angles.
