![]() The R&S ®Series4200 radio family is one of the newest available on the ATC market. The R&S ®GB4000V adheres to EUROCAE ED-137. Their compact design minimizes space requirements in operator consoles. The R&S ®GB4000T control unit and the R&S ®GB4000V audio unit are IP-based components for small-scale systems that consist of only a few working positions for air-ground communications. TheR&S ®VCS-4G adheres to EUROCAE ED-137. The IP-based distributed architecture provides additional benefits, such as the integration of new services (e.g. It supports traditional VCS services, such as air-ground communications, intercom and telephony services. The R&S ®VCS-4G meets the highest standards for availability, reliability and safety. It fulfills the needs of both small-scale and large-scale area controlcenters (ACC)aswellasbackupsystemsand tower installations. The R&S ®VCS-4G voice communications system (VCS) takes full advantage of IP technology, making it scalable, cost-effective, and ready for the future. This eliminates the need for complex and costly integration work and helps to minimize project risks. The company provides system solutions from the microphone to the antenna. Rohde & Schwarz offers a wide selection of VoIP-based products designed specifically for the needs of ATC customers around the world. Your partner from the microphone to the antenna Customers who select equipment that meets this standard can be assured that the various system components interoperate properly with one another. This standard was defined jointly by EUROCAE, ATC authorities and ATC equipment manufacturers. The ED-137 issued by EUROCAE specifies the use of IP for voice communications in ATC environments. The direct result is higher reliability and availability. With the intelligence distributed over various elements, a failure at one part of the system does not affect operation in the rest of the system. VoIP systems, however, migrate intelligence away from the network core to peripheral equipment. Reliability in TDM systems typically depended on duplicating high-cost centralized equipment. This has a direct impact on your return on investment. As a result, ATC authorities no longer need to invest in large systems right from the start. In contrast, modern IP-based systems make use of distributed network intelligence and do not require a central switching entity, thereby providing pay‑as-you-grow scalability. In the past, TDM-based systems relied on large centralized switching nodes. Using this IP infrastructure also for voice creates synergies in procurement, operation and maintenance, resulting in significant savings. Many ATC system operators are already using IP networks to transmit radar and flight plan data. It also provides significant financial advantages. VoIP offers operational functionality and flexibility that would have been unthinkable with the TDM-based systems of the past. The challenges now facing the ATC world will be met with the increasing use of IP technology.
