Ubidyne’s active antenna systems support DAS, macro and small cells

January 7, 2013

Ubidyne has announced that its advanced active antenna platform is now able to support the first fully digital Distributed Antenna System (DAS) for extending mobile broadband coverage (LTE, UMTS) to indoor or outdoor data hot-spots. Based on its digital architecture, the Ubidyne solution supports high-capacity, multiband, multi-standard and multi-operator installations for environments such as university campuses, airports, shopping malls, stadiums and offices as well as other dense urban indoor and outdoor deployments.

Up to 16 independent single-band to quad-band remote antennas can be strategically located and connected using any grade of fiber to a central hub (uBhub), based up to 10 km away. Multiple hubs can be cascaded for coverage solutions in large buildings. With full digital control of each transceiver/radiator, a single Ubidyne DAS solution can be used by different wireless carriers in the same location to meet specific coverage and capacity needs. Other benefits include rapid trouble shooting for reduced maintenance costs, self-calibration and easy health checks.

Ubidyne's digital architecture also supports the combination of different radio solutions. For example, for indoor/campus locations, the DAS system can be connected with a high capacity small cell, also based on Ubidyne's platform architecture. Finally, the digital architecture enables future-proofed cooperative antenna solutions with distributed MIMO for high capacity hot-spots.

"80 percent of all wireless traffic happens indoors but existing DAS solutions reach their capacity limitations and face operational challenges because of analogue distribution of the RF signal," said Michael Fränkle, CEO at Ubidyne. "With the Ubidyne digital DAS platform, system and antenna vendors can now upgrade their solutions to meet growing capacity demands. Already, countries such as the US, Korea and Japan and some European regions where LTE is being deployed and where mobile broadband traffic is growing exponentially, are running out of capacity in hot-spots."
