| IPWireless announces the world's first, fully interoperable, 3G network for mobile voice and broadband data |
||
IPWireless has successfully completed the world's first interoperability (IOT) and co-existence testing between UMTS TDD (TD-CDMA) and UMTS FDD (WCDMA) networks at Nortel Networks wireless headquarters in Châteaufort, France. The test, completed during a trial of the IPWireless TDD solution, demonstrated that both FDD and TDD standards of 3G UMTS can co-exist in the same cell site and interface together as one network solution.
The tests also showed the co-existence of both FDD and TDD Node Bs at the same cell site without any interference or degradation of service using paired and unpaired spectrum allocations. These findings prove conclusively that mobile network operators can safely offer the high-bandwidth low-latency services available on a TDD network on the cell sites with existing or planned FDD deployments.
