Qualcomm and Ericsson Tuesday said they’ve Successfully completed an inter-company Category 9 Carrier Aggregration (CA) interoperablity testing.
According to press release, a Qualcomm modem was used in conjuction with Ericsson LTE-A network infrastructure. Anritsu’s MD8430A/RTD LTE Simulator was used for testing with three LTE FDD or TDD component carriers, each with a bandwidth of up to 20 MHz, allowing Category 9 end-to-end peak data rates of up to 450 Mbps in the downlink.
Carrier Aggregation is a feature of LTE Advanced and is aimed at allowing service providers to aggregate disparate swaths of spectrum.
Serge Willenegger, vice president of product management, Qualcomm Technologies, called the tests a “first.”
The equipment used for the tests was based on Ericsson’s commercially available 14B software release supporting the company’s multi-standard RBS 6000 family of base stations for macro and small cell networks.
Ericsson noted that it supports all bandwidth and frequency combinations for up to 60 MHz 3x Carrier Aggregation.
