Chipset, device makers achieve 4x4 MIMO testing capability

Development of LTE and LTE-Advance devices gets a boost with Anite claiming to be the first to offer chipset and device manufacturers the ability to test their 4x4 downlink (DL) MIMO designs and products.

The milestone was achieved in close collaboration with a device manufacturer using the company's Development Toolset for early stage testing. MIMO is a key feature in LTE-Advanced.

Advanced MIMO antenna configurations where both the base station and the device are equipped with multiple transmit/receive antennas are leading to an increased need for device testing prior to market launch. 4x4 DL MIMO capable devices require greater antenna separation/isolation and are therefore used in devices with larger form factors such as phablets, laptops with inbuilt modems and set-top boxes, as well as in various automotive applications.

Anite's capability to test 4x4 DL MIMO follows its earlier success in demonstrating Carrier Aggregation of two component carriers of 20MHz each, resulting in Category 6/7 downlink data rates of 300Mbit/s.

"Complex antenna configurations such as 4x4 DL MIMO require advanced testing capability. Anite's leading product roadmap and its collaborative engagement with key industry partners enable device manufacturers to accelerate their designs of LTE and LTE-Advanced products," says Paul Beaver Products Director at Anite.
