From SISO to MIMO – taking advantage of everything the air interface offers (2):
Part 1 of this article in number 192 discussed SISO, SIMO and MISO systems (see box below) and how they are used in GSM, WCDMA and WiMAX. The tests defined as part of the certification process were also discussed along with how they can be implemented using instruments from Rohde & Schwarz. Part 2 will cover MIMO systems, i. e. the variants used in the different standards, the relevant test scenarios and their implementation.

2G and 3G interoperability tests – from real networks to the lab: R&S ® CRTU Protocol Test Platform
In addition to conformance tests, interoperability tests (IOT) are becoming increasingly important. R&S® CRTU users have an advantage in this respect: They can transfer these tests from real networks to the lab and perform them in an altogether quicker and more cost-efficient manner. The new R&S® ITS replay tool in conjunction with the R&S® ROMES coverage measurement software makes this possible.
