Scalable PMR networks: The architecture is what counts: TETRA Mobile Radio System ACCESSNET-T
The Mobile Radio Communications Architecture IpMCA from Rohde&Schwarz defines a comprehensive technical and commercial requirements profile for digital PMR networks. If these requirements are taken into account when planning mission-critical communications networks and are completely fulfilled in the implementation phase, there will be nothing to stop these networks from being adapted quickly and costeffectively during their entire operational life.

Measurements and signaling tests in the dual transfer mode: Universal Radio Communication Tester R&S CMU200
The dual transfer mode (DTM) an expansion of the GSM mobile radio standard permits voice telephony and data transfer at the same time. The R&S CMU200 is well prepared to meet these requirements: With the R&S CMU-K44 software option, the mobile radio tester can simulate a DTM-compatible GSM base station and thus perform a variety of measurements and signaling tests on mobile radio devices.

Standardized test solutions for PoC mobile phones: R&S CMU200 / R&S CTRU-G / -W
PoC (push to talk over cellular), the modern version of walkie-talkie communication, is a very promising new voice communications service in mobile radio networks. Voice messages are directly sent to one or more predefined subscribers at a keystroke. This bidirectional radio service also used as PTT (push to talk) with only slight differences is based on packet-switched voice transmission in GPRS, WCDMA(UMTS) or CDMA2000 networks, for example. This new form of group communications opens up new possibilities both for business customers and private users and is thus a cost-efficient alternative to telephony and SMS.

Transmitter and receiver measurements for Bluetooth V2.0 + EDR: Bluetooth RF Testers R&S CBT / R&S CBT32
With the new Bluetooth standard V2.0 + EDR (enhanced data rate), you can use I/Q modulation methods for Bluetooth packets. For the RF Testers R&S CBT and R&S CBT32, Rohde&Schwarz now offers an option to carry out transmitter and receiver measurements on EDR Bluetooth devices and modules. The option supports the loopback test mode and, owing to the very high measurement speed, yields a high throughput in production.

Perfectly simulated: GPS signals for complex localization scenarios: Signal Generators R&S SMx
Due to the increasing use of the global positioning system (GPS) in the automobile and handheld industries, it has become a popular technology. Experts agree that GPS and later also Galileo, which is the European counterpart will open up yet another large market: The term Assisted GPS is already being used for the combination of mobile radio with satellite navigation. The R&S SMU-K44 option expands the large scope of functions of the R&S SMx signal generator family for generating real GPS signals.

Trust is good, control is better DVB-T monitoring: DTV Monitoring Receiver R&S ETX-T
Numerous DVB-T transmitter networks have already started regular operation. New networks are continuously being added. The amount of money spent on transmitter technology is and has been significant, whereas investments in monitoring T&M equipment are often considered of minor importance. However, downtimes can be very expensive.

Generating and analyzing transport streams for DVB-H:
The DVB-H standard has been specified for supplying broadband data services to mobile terminals. In contrast to DVB-T, the emphasis is on robust transmission, support of mobile reception and saving energy in terminals. Rohde&Schwarz provides new software and options for generating and analyzing DVB-H transport streams.

Transportable monitoring system for frequencies up to 110 GHz: Transportable Microwave Monitoring System R&S TMS500
Many transmitters operate above 3 GHz, the frequency limit of conventional receivers. Some of them are used for WLAN applications, but also for broadcasting and TV satellites as well as for microwave and radar systems. It is necessary to monitor all these transmitters, determine their data in order to plan reliably, and find possible interference in this range.
