As an alternative to the classical handover scenario, the two base stations could also be used as cooperating base stations serving the terminals in the handover region jointly, as discussed in the context of IMT-Advanced. In Table 12.2, different potential measurement setups discussed in the previous section, including the parameters/properties of the system that can be evaluated, are summarized. 12.5 Summary In order to evaluate the performance of multiantenna wireless communication sys- items, classical measurement techniques known from antenna measurements, such as anechoic chambers, are no longer sufficient. The measurement setups for (multi) antenna measurements presented in the first part of this chapter show how rever- beration chambers can be used as an alternative to current techniques. The accu- racy of the reverberation chamber measurements has been analyzed and compared to classical antenna measurements where this is possible. The methods developed for single-antenna characterization can be taken a step further to evaluate the performance of different multiantenna setups and algo- rithms, such as diversity combining. These diversity measurements require a fading environment and are therefore perfectly suited for reverberation chambers. If base station simulators are used for measurements, it is even possible to investigate the performance of different antenna setups, in terms not only of power gains but also of BER. Current state-of-the-art measurements in reverberation chambers even include throughput measurements of wireless links. Although link measurements of wireless systems in reverberation chambers are nowadays well established and have even made their way into
