Cambridge Broadband has completed a successful test of its VectaStar 3500 Fixed Wireless Access system with Danske Telecom of Denmark. Financial terms of the deal were not disclosed.After extensive system trials to evaluate VectaStar’s performance in terms of range, data rates and quality of service, network deployment will continue with deliveries of the next 10 base stations.In what is being described as probably the toughest customer test so far, a tier one global carrier is using Danske Telecom and the VectaStar system to deliver a guaranteed data rate of 10Mbps. Although using just a fraction of the VectaStar sector capacity of 60Mbps, this is believed to be a record for any 3.5GHz system in a live deployment. Modulation schemes from QPSK to 64QAM have been tested, plus services including transmission of DVD quality video, full and fractional E1, and high-speed file transfer.Danske Telecom has also tested VectaStar’s self-backhaulcapability, allowing the telco to despatch aggregated customer traffic from a VectaStar base station to Danske Telecom’s point of presence using a standard VectaStar radio link. The procedure was a cheaper alternative to expensive fibre or microwave point-to-point backhaul links.
