Motorola Completes Its First UMTS Voice Call in Germany

date: March 14, 2002

Motorola has successfully completed its first Universal Mobile Telecommunications Systems (UMTS) voice call in Germany that is in compliance with the 3rd Generation Partnership Project (3GPP) Standard Release 99 version. The call was made at Motorola's UMTS laboratory in Wiesbaden using the AMR (Adaptive Multi-Rate) CODEC specified by the 3GPP. Motorola previously announced a 144 Kb/s data call over the same Motorola UMTS Radio Access Network (UTRAN).

With our first UMTS voice call in Germany, Motorola has proven its UTRAN is compatible with the 3GPP Standard Release 99. "This achievement is a major breakthrough on the way to the successful deployment of UMTS networks in Germany. It establishes another basis to specifically optimize our technologies for commercial implementation with network operators," explains Jerry Chard, Director, UMTS Infrastructures at Motorola GmbH.

The successful lab test reflects Motorola's many years of experience in real-life voice and packet data communications via mobile networks. For example, Motorola implemented a nationwide GPRS network for a major German network operator in early 2001. Leveraging the expertise from that network deployment, Motorola was able to use Node B (base station) products that are compliant with the European UMTS specifications and standards early on in its lab tests.

Motorola offers UTRAN solution with features like intelligent coverage that will give operators the opportunity to achieve significant savings, as fewer cell sites will be needed to meet coverage quality requirements. The core element of Motorola's UMTS solution is its Node B that is significantly smaller and lighter than comparable products (at just 257 liters in volume and 145 kg in a typical configuration). As a result the UMTS Node B can be stacked with existing Motorola GSM BTSs, while providing improved performance. This compact Node B provides operators with the opportunity for greater site re-use and easier site acquisition, which can result in less capital expense and faster time to market.
