Companies successfully complete interoperability testing of three-band Carrier Aggregation using 40 MHz split across three bands with Category 6 Snapdragon 810 processor
Testing shows readiness of the next evolution step for LTE-Advanced for operators with multiple LTE bands
Enabling advanced operators like SK Telecom to increase LTE-Advanced data rates by up to 33%
Ulm, Germany - Nokia Networks and Qualcomm Technologies, Inc., a wholly-owned subsidiary of Qualcomm Incorporated (NASDAQ: QCOM), have completed interoperability testing of LTE-Advanced three-band Carrier Aggregation (3x CA), allowing more operators to achieve subscriber data rates of up to 300 Mbps in their network environments.
The tests utilized the Nokia Flexi Multiradio 10 Base Station and Qualcomm Snapdragon(TM) 810 processor and allows operators, such as SK Telecom, to offer data rates of up to 300 Mbps to their subscribers using a network of three frequencies (20 MHz 10 MHz 10 MHz). 3x CA provides an alternative option to operators to reach 40Mhz carrier aggregation, as this option was previously available only to the operators with at least two bands of 20 MHz bandwidth each.
3x CA is a step towards enabling higher data rates for LTE operators around the world that face fragmented spectrum. This follows the worlds first commercial introduction of two-band Carrier Aggregation (10 MHz 10 MHz) in Korea in 2013 and the bandwidth expansion (20 MHz 10 MHz) to offer peak downlink rates of up to 225 Mbps on smartphones since June 2014.
By applying Carrier Aggregation to more than two bands, we enable operators to turn their investment in 4G frequency spectrum and networks into marketable higher data rates, said Tero Peltola, head of FDD-LTE business line at Nokia Networks. With this interoperability test campaign, we have verified that our Carrier Aggregation implementation works perfectly with user devices based on Snapdragon processors.
The interoperability tests with Qualcomm Technologies were performed in September at the Nokia Networks laboratory in Ulm, Germany, and involved 3GPP bands 1, 3 and 5 as used by SK Telecom. Nokia Networks launched its 3x CA capability in February. Although LTE-Advanced Carrier Aggregation is standardized within 3GPP, interoperability testing is vital to prove the functionality works using each vendors software.
The completion of these 3x CA interoperability tests helps expand the scope of Category 6 LTE and thereby enhances LTE user experience worldwide, says Serge Willenegger, vice president of product management for Qualcomm Technologies. Continuing evolution in networks and user device chipsets together is the fundamental enabler for making mobile broadband faster for more subscribers around the world.
Nokia Networks is introducing 3x CA to commercial networks later this year. The Snapdragon 810 processor is expected to be available in commercial devices by the first half of 2015.
