Nokia Networks and Saudi Telecom Company (STC) demonstrated TDD-FDD Carrier Aggregation using a commercial chipset.
The demonstration was carried out using a new band combination of FDD 1800 MHz and TDD 2300 MHz.
Nokia Networks said high frequency bands have limited uplink coverage, but operators can significantly extend TDD coverage with TDD-FDD carrier aggregation with no additional changes to the network. Load balancing between TDD- and FDD-LTE networks ensures the best coverage and speed for all subscribers in both networks.
