Two former rivals are once again teaming up, with Qualcomm Technologies and Ericsson successfully completing an inter-company interoperability testing of LTE Category 9 connectivity with download speeds of up to 450 Mbps.
Testing was conducted using Qualcomm's next-generation LTE-Advanced modem and Ericsson LTE-A network infrastructure. The Category 9 speeds allow mobile users to get download speeds of up to 450 Mbps, with the ability to reliably use more connectivity-based applications in greater coverage areas.
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, which allows for "unparalleled" user experience on operator networks using multi-frequency deployments, the company says. Ericsson supports all bandwidth and frequency combinations for up to 60 MHz 3x carrier aggregation, providing users with speeds of up to 450 Mbps.
Qualcomm is also conducting demonstrations with Anritsu, which announced it has successfully demonstrated stable peak data throughput for a Category 9 LTE device and network simulator using 3x carrier aggregation (3x CA).
Using devices featuring an LTE Advanced modem from Qualcomm and Anritsu's MD8430A/RTD LTE Simulator, the company says it was able to successfully show support of 3x carrier aggregation 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. The achievement builds on Anritsu's announcement of Category 6 capability with Qualcomm in January.
Anritsu says the MD8430A is a scalable LTE network simulator, with six models ranging from Functional Test Model (FTM) to Enhanced Test Model (ETM), and available software options for both LTE FDD and TDD for any model. The associated Rapid Test Designer (RTD) graphical test software enables quick scripting of tests, with an intuitive user interface as well as available layer 3 and lower-layer libraries.
In October, Nokia Networks and Qualcomm Technologies completed interoperability testing of LTE-A three-band carrier aggregation (3x CA) with a Category 6 Snapdragon 810 processor, allowing more operators to achieve subscriber data rates of up to 300 Mbps in their network environments.
Those tests used the Nokia Flexi Multiradio 10 Base Station and Qualcomm Snapdragon 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). The 3x CA provides an alternative option to operators to reach 40 Mhz carrier aggregation, as this option was previously available only to the operators with at least two bands of 20 MHz bandwidth each.
