What UMTS holds for the future is already materializing in GSM networks: high-speed data ransmission. This is made possible with the 2.5G standards GPRS and EGPRS. While EGPRS mobile phones are still in the development stage, GPRS mobiles are already on the market. The new 2.5G standards mean new measurement challenges for manufacturers of mobile phones. For example, new approaches have to be taken in receiver measurements. The Universal Radio Communication Tester
R&S CMU200 from Rohde & Schwarz provides full receiver test capability not only for GPRS, but now for EGPRS mobile phones as well.
