The latest enhancements including EDGE Evolution functionality and the VAMOS feature are supported, while future implementations will reflect

Presented at GSMA MWC 2014SwissQual, a Rohde & Schwarz company, presented the QualiPoc Freerider II at the GSMA Mobile World Congress 2014 in Barcelona. The multitechnology, smartphone-based benchmarking and optimization tool for mobile radio networks combines a wide-range of benchmarking function and comparison capabilities with a smartphone's real end-user experience. The mobile tool can be conveniently

Presented at GSMA MWC 2015Rohde & Schwarz presented an automated solution for reliable and reproducible end-to-end conformance testing of eCall and ERA-Glonass modules at the GSMA Mobile World Congress 2015 in Barcelona. The setup enables to test whether the IVS modem is able to trigger an emergency call, send the correct MSD data to the 2G/3G network, establish a voice connection with the PSAP and

Rohde & Schwarz Webinar from December 03, 2013eCall is an interoperable in-vehicle emergency call system designed with the objective to greatly reduce response times in the case of an accident in order to save human lives. In contrast to other already existing private services, eCall is based on a pan-European standard and is required to be introduced for all new car models from 2015 onwards by the

A comprehensive introduction of the VAMOS technology and its test solutions for both user equipment and base stations.VAMOS (Voice services over Adaptive Multi-user channels on One Slot) can double the voice capacity of existing GSM mobile communication networks and is specified in 3GPP GERAN (GSM/EDGE Radio Access Network) Release 9. Supporting two voice users on a single radio resource requires enhanced

Rohde & Schwarz webinar from January 15, 2014An increasing number of power amplifiers support envelope tracking technology to improve efficiency and therefore extend battery life in smartphones and tactical radios. This webinar explains the basic principles of envelope tracking and the test challenges involved in this technology. As envelope tracking is often used in combination with predistortion,

Positioning & Navigation Location based service (LBS) applications based on A-GNSS, OTDOA and eCID are expanding strongly.LBS is a growing market segment involving determining the location of a mobile device for either emergency services applications (E911, eCall, ERA-Glonass) or commercial applications such as social media, RCS, mapping and geo-based advertising. Increasingly sophisticated smartphones

GSM (Global System for Mobile Communications) networks have been deployed worldwide as second-generation mobile communications systems. GSM originally was developed to transmit voice, but it is also able to transmit data with a max. load of 9.6 kbit/s in the downlink and uplink. With the technical interim solution HSCSD, the max. data rate was increased to 43.2 kbit/s in the downlink and 14.4 kbit/

Unified platform for LBS and performance analysis presented at GSMA MWC 2016 Rohde & Schwarz demonstrated complete location based services as well as PQA test coverage from R&D, carrier acceptance through conformance at the GSMA Mobile World Congress 2016 in Barcelona.High-volume multi-DUT production testing presented at GSMA MWC 2016 Rohde & Schwarz presented the R&S®CMW100 multi-device communications
