11/15/2004 - Artesyn Communication Products, a subsidiary of Artesyn Technologies, Inc. (Nasdaq: ATSN), and a leading supplier of blade products for telecom OEMs, announced that it has joined the Open Base Station Architecture Initiative (OBSAI).
OBSAI, currently numbering more than 100 members, was launched in October 2002 by leading vendors of base stations, modules, and components to create a set of specifications for open base station transceiver systems (BTS). OBSAI defines a high-level modular BTS architecture and provides detailed specifications for the internal interfaces among modules. This open framework gives BTS designers easy access to interoperable, best-of-breed components from a wide range of vendors, thereby reducing the development time and cost associated with building new base station product lines. The open framework will also benefit network operators by reducing BTS cost and enabling them to bring new and advanced functions to market more quickly.
"Industry experts are forecasting explosive growth in the wireless infrastructure equipment market, in excess of 20% per year for WCDMA and CDMA2000 equipment alone," said Todd Wynia, vice president of marketing at Artesyn Communication Products. "Meeting this demand will require extensive deployment of advanced base station transceiver systems with scaleable, upgradeable wireless capabilities. Artesyn believes that OBSAI provides an excellent framework for helping telecom OEMs get to market fast with cost effective, next-generation BTS products, and we are actively exploring making our BTS products available in an OBSAI form factor."
Artesyn currently offers a family of intelligent WAN interface modules that have the features necessary to perform the transport function in a base transceiver station. These modules, which combine an MPC8260 PowerQUICC II controller with up to eight E1/T1 spans, are packaged in a PMC (PCI Mezzanine Card) form factor. The transport module enables the base transceiver station to communicate with base station controllers and the PSTN (Public Switched Telephone Network). Artesyn's modules could be migrated to an OBSAI form factor as the market for open base stations develops.
OBSAI is an open framework for building base station transceiver systems. The BTS takes digital information received from base station control systems, converts it to an analog RF signal, and sends it to the cell site antenna for transmission onto the cellular network. The BTS also takes analog RF signals received from the antenna, converts them to a digital format, and sends them to the base station controller.
OBSAI defines the physical form factor and key functional modules, as well as the interfaces between those modules. The OBSAI functional architecture defines four principal modules: the radio module, the baseband processing module, the transport module and the control module. The radio module connects the base station to the antenna. It provides wireless transmit and receive (WCDMA, GSM/EDGE, CDMA2000, etc) as well as RF amplification and conversion between analog RF signals and digital baseband signals. The baseband module provides channel modems that perform baseband processing for the radio module. The transport module provides adaptation that connects the base station to the external network via standard interfaces such as E1, T1, IP, and ATM. The control module supervises all base station activities, monitors the base station and reports its status and performance to base station managers or element management systems.
The OBSAI reference architecture defines three reference points: Reference Point 1 (RP1), Reference Point 2 (RP2), and Reference Point 3 RP3). RP1 defines the interface between the control module and the other three modules. It defines the exchange of control, performance, status, alarm, and provisioning data between the control and clock modules and the rest of the BTS modules. It also defines the exchange of clock and synchronization signals. RP2 defines the exchange of user data between the transport block and the base band module. RP3 defines the exchange of user data and control information between the base band module and the radio module.
