Vodafone Implements FDD/TDD Carrier Aggregation

Vodafone-Implements-FDD/TDD-Carrier-AggregationVodafone will be first to take advantage of LTE FDD/TDD network convergence and carrier aggregation, starting with its network in Portugal, thanks to Ericsson and Qualcomm.

This move will allow the operator to combine the best characteristics of LTE FDD and TDD modes. Adding TDD to the already installed FDD network significantly enhances the total downlink data capacity and improves subscribers’ mobile broadband experience. In addition, FDD/TDD carrier aggregation extends the app coverage of the TDD layer by up to 230 percent.

Using only a software update to Ericsson baseband hardware already operating in the network, Ericsson’s Networks Software 15B release enables simultaneous operation of LTE FDD and TDD.

Per Narvinger, head, LTE, Ericsson said, “Combining TDD with low-band FDD spectrum will improve the high-band TDD coverage area, and the TDD spectrum will significantly improve the overall downlink throughput. With global availability of TDD spectrum, we regard FDD/TDD carrier aggregation as a key technology to further improve user experience for customers worldwide.”

Enrico Salvatori, SVP and president, Qualcomm Europe said, “We are delighted to work with Ericsson and Vodafone on the latest LTE-Advanced multimode solutions and to deliver consumers an improved mobile broadband experience. The Snapdragon 810 processor with X10 LTE builds upon our leadership in LTE-Advanced technology by supporting carrier aggregation across LTE TDD and LTE FDD.”

Vodafone’s current deployment for the trial in its commercial network in Portugal uses 15 MHz of band 3 (FDD 1800) and 20 MHz of band 38 (TDD 2600) and tests are supported by the Qualcomm Snapdragon 810 processor with X10 LTE running in a device.
