Andrew Corporation and ipwireless have jointly developed a product enables them to combine transmission of two 3G radio technologies onto a single cell site antenna. This new duplexer allows wireless operators to deploy both UMTS Frequency Division Duplex (FDD) and UMTS Time Division Duplex (TDD) systems using a single antenna, efficiently taking full advantage of their 3G spectrum to deploy new broadband services and offload traffic from their circuit switched networks. Now commercially available, the UMTS FDD/TDD duplexer has already been proven in a number of trials across Europe, and will be used by a number of operators including the recently announced UMTS TDD deployment by Sonaecom in Portugal. more
