Mobile broadband specialist IPWireless has completed initial interoperability and coexistence testing between UMTS TDD (TD-CDMA) and UMTS FDD (WCDMA) networks at Nortel Networks wireless headquarters in Chbteaufort, France.

The test, completed during a trial of the IPWireless TDD solution, demonstrated that both FDD and TDD standards of 3G UMTS can coexist in the same cell site and work together as one network solution.

They also showed the coexistence of both FDD and TDD Node Bs at the same cell site without interference or degradation of service using paired and unpaired spectrum allocations. The results mean mobile network operators can safely offer the high-bandwidth low-latency services available on a TDD network on cell sites with existing or planned FDD deployments.

"This is another important step for IPWireless, demonstrating that there is a UMTS solution for operators' unpaired TDD spectrum which can leverage and work seamlessly with other UMTS solutions," Chris Gilbert, CEO of IPWireless, said in a statement.

The test integrated IPWireless' TDD Radio Access Network via the Iups interface with Nortel Networks' packet core solution, which is deployed by a number of major European operators.

Alain Biston, president and general manager, UMTS Networks, Nortel Networks, said the "test with IP Wireless demonstrates the high interoperability of our intelligent packet core solution with multiple wireless access technologies."

IPWireless is supplying its 3GPP standards compliant UMTS TDD Mobile Broadband technology equipment including Node Bs, Integrated Network Controllers and end user PC cards to OEMs around the world. The technology offers laptop and PDA users access to mobile data services at speeds up to 1.5Mbit/s via the PC card.
