Anritsu Company announces exclusive support for LTE 4×4 Multiple-In-Multiple-Out (MIMO) Carrier Acceptance Test (CAT) requirements for a major US carrier, the company said.
This new coverage, based on the ME7834LA Mobile Device Test Platform, builds on the leading 3G and LTE CAT test offering for this carrier. With this announcement, Anritsu is the first test solution provider in the world to offer a device acceptance solution for 4×4 MIMO.
MIMO is an essential part of LTE that allows an increase in data rates without adding bandwidth. This is accomplished using “spatial multiplexing” of multiple streams of data on the same carrier. A 4×4 MIMO downlink configuration uses four antennas on the base station to transmit four simultaneous streams of data, and four antennas on the device to receive and separate the mixed streams.
Combination of MIMO and LTE Advanced Carrier Aggregation (CA) can result in extremely high data rates, as evidenced by Anritsu´s recent announcement of 1 Gb/s IP throughput using 3CA and 4×4 MIMO.
The ME7834LA is a scalable GCF, PTCRB, and carrier-validated test system that enables certification of 3G and LTE devices to industry and carrier standards. The ME7834LA provides test coverage for 3GPP 36.523 and 34.123, as well as a wide portfolio of CAT test plans across multiple operators. For existing ME7834L platform users, an upgrade path is available with support for 4×4 MIMO and multi-carrier aggregation, as well as legacy test cases.
