APPARATUS AND METHOD FOR PROVIDING RADIO ENVIRONMENT TO TEST WIRELESS COMMUNICATIONS EQUIPMENT

摘要

PURPOSE: An apparatus and a method for recreating radio frequency(RF) field conditions are provided to allow wireless communications equipment testing and optimization without repeated field testing by using previously collected data. CONSTITUTION: Cell sectors in a lab setting are connected to a computer-controlled, multi-channel attenuator which based on variable control values extracted from the field test data, creates a variable RF loss along a plurality of forward(cell sector to mobile) and reverse(mobile to cell sector) attenuation paths. Such variable control values represent the RF loss which occurred between the network cell sectors and the mobile diagnostic device.
