Powerwave Technologies says the Powerwave Microwave Group has been awarded a contract from ATENIT Communication in Sweden to be the exclusive supplier of Ethernet microwave communication solutions, which will be used in Scandinavia's first commercial UMTS-TDD communications network, as well as additional networks in Europe. Specifically, the agreement is expected to facilitate microwave delivery in the Nordic, Baltic and Eastern European areas, where ATENIT plans to build licensed TDD networks.
"This deal demonstrates Powerwave's strong capabilities in software-based microwave solutions starting from an IP/Ethernet approach, instead of more traditional ITU/Telecom solutions," stated Leo F.J. de Meere, vice president of sales at Powerwave's Microwave Group.
UMTS-TDD Mobile Broadband technology, also known as TD-CDMA, is a packet data implementation of the UMTS standard. Unlike WCDMA which uses FDD (Frequency Division), UMTS-TDD uses Time-Division-Duplexing (TDD) and is designed to work in a single unpaired frequency band. The technology enables high speed, low latency to provide broadband and other packet services to users at home, at work, or on the road.
One of the significant benefits of using TDD is that TDD supports variable asymmetry, meaning an operator can dictate how much capacity is allocated to downlink versus uplink. As the traffic patterns for data typically favor the downlink, this results in better use of spectrum assets and higher efficiency for network operators.
Powerwave is a member of the Global UMTS-TDD Alliance."
