First LTE-Advanced (LTE-A) Carrier Aggregation (CA) test case

June 26, 2013 // By Graham Prophet
Anite has submitted the first LTE-Advanced (LTE-A) Carrier Aggregation (CA) test case, developed using Anite’s Conformance Toolset and in collaboration with major North American and Asian chipset and device manufacturers.

Carrier Aggregation, a key feature in LTE-A, allows MNOs to achieve higher spectrum efficiency, faster data rates through aggregation of narrower spectrum bandwidths instead of large contiguous blocks of spectrum. As a result, the company asserts, of Anite driving the development of LTE-A CA testing capability, device and chipset manufacturers will be able to accelerate the development of LTE-A products. These submissions were based on initial verifications submitted by Anite to RAN5 in April 2013 - Anite has been responsible for around two thirds of all LTE protocol test case verification submissions to RAN5. This key achievement is a stepping stone towards validation, leading to the inclusion of these test cases in both GCF and PTCRB device certification requirements. The intent of LTE-A is to equip mobile data users with the equivalent of a fixed-line connection.

As a result of Anite driving the development of LTE-A CA testing capability, device and chipset manufacturers will be able to accelerate the development of LTE-A products ahead of formal GCF and PTCRB certification, expected to commence in the second half of 2013. Since 1997 Anite has consistently pioneered RAN5 conformance test case submissions. Its protocol testing expertise and experience has enabled it to achieve a leadership position, which it seeks to maintain as new technologies, such as LTE-A, are introduced. To date, Anite has been responsible for around two thirds of all LTE protocol test case verification submissions to RAN5.

Used in these developments was the Anite 9000 network simulator platform for lab-based device testing, which is used by the industry to execute development, conformance, interoperability and performance testing. The same platform was used to achieve industry-leading peak data rates for LTE-A CA, which Anite was first to announce in February this year.

“The submission of these latest test cases to RAN5 demonstrates the strength of our collaborative relationships with the leading chipset and device manufacturers in addition to clear product maturity. These
