LTE-A will extend the features of LTE to deliver the equivalent of a fixed-line broadband experience to the end user, promising peak download data rates of around 3Gbps, which will allow subscribers to work effectively ‘on the move’. However, achieving these peak data rates over a mobile network poses one of the biggest challenges the industry has ever had to face due to the complexity of the LTE-A technology coupled with limitations set by form factors and frequency bandwidths.
Carrier aggregation allows mobile operators to achieve higher spectrum efficiency and superior data rates through the use of narrower spectrum bandwidths instead of large contiguous blocks of spectrum, which is scarce and not easily obtainable. Anite achieved these peak data rates using its Development Toolset solution and commercial third party devices for the 10+10 MHz bandwidths required by leading US mobile operators.
Anite’s LTE-A protocol Development Toolset now supports key LTE-A features such as carrier aggregation of up to 20+20 MHz bandwidth and also provides support for a 4x2 antenna configuration. This will enable chipset manufacturers to develop reliable LTE-A products in line with their milestones. With its simple to use graphical interface, Development Toolset speeds up testing programmes and enables users to test across a wide range of technologies. Users have access to a library of test cases, which contribute to enhancing the productivity from the very early stages of the development of a new chipset or device.
“Working as a strategic partner to a number of leading chipset manufacturers, Anite’s LTE-A solutions offer industry leading data rates”, said Paul Beaver, Products Director at Anite. He continues, “Our lab-based test solutions ensure that LTE-A devices and chipsets are rigorously tested in a controllable and repeatable way – this leads to significant time and cost savings.”
