Compatible with the open base station architecture initiative (OBSAI) RP3-01 interface definition, the RFS development underpins important new wireless network deployment and management strategies.
By leveraging the bandwidth and flexibility of fibre-optic technologies, the RFS RRH system permits Base Transmitter Station (BTS) to antenna separation distances of up to 15km. This allows the BTS to be located in more easily acquired sites, remote from the mast and radio head/antenna assembly. In addition, the RFS RRH fibre-optic link offers ongoing opex savings, courtesy of what RFS says is an almost loss-free BTS-to-tower top fibre link.
The unit's total throughput capacity of over 3Gb/s ensures that the RFS RRH is well-placed to support powerful RRH networking topologies, such as 'daisy chain', 'ring' and 'tree-and-branch.' It is, in addition, compatible with the OBSAI RP3-01 interface definition.
With close to 130 companies in the industry, OBSAI aims to establish a more open base station market. Its company members have produced and made available a complete set of open interface and module hardware connectivity specifications addressing the areas of transport, control, baseband and radio, within the base station subsystem.
André Doll, RFS Vice President Product Management RF Conditioning, believes: "OBSAI-compatibility ensures that our RRH solution will easily be modified to support the widest range of third-generation (3G) and 3.5G wireless technologies, including Worldwide interoperability for Microwave ACCess (WiMAX)." It is predicted that emerging WiMAX broadband wireless data networks will have specific needs for such active tower-top solutions - particularly in the early stages of network deployment in dense inner-city areas. Commercial launch is planned for 2007.
* RFS has released the latest edition of its comprehensive product catalogue, RFS Products: Infrastructure Solutions, featuring over 3,000 RFS products across eight product ranges. A new feature is seven 'industry solutions' whereby each provides a detailed system illustration demonstrating how RFS's individual product groups can be integrated together into end-to-end RF solutions. The printed version of the fourth RFS Products catalogue is available now from local RFS sales representatives.
