LTE-Advanced Pro – paving the way for 5G NR

LTE was introduced to provide the first truly global, high data rate and packet-optimized system.

Long term evolution (LTE) ensures subscribers fast and smooth access to the mobile internet. The first LTE commercial network was launched at the end of 2009. LTE-Advanced, the next evolutionary step, added significant improvements, such as carrier aggregation, to further enhance delivery of mobile broadband services. LTE-Advanced Pro builds the basis for 5G, the next major step in wireless communications – for example with the introduction of NB-IoT for massive machine type communications (mMTC).

Long term evolution (LTE) specified in 3GPP Releases 8 and 9
LTE-Advanced (LTE-A) specified in 3GPP Releases 10 to 12
LTE-Advanced Pro (LTE-A Pro) specified in 3GPP Releases 13 to 15

Rohde & Schwarz test solutions for LTE/LTE-A/LTE-A Pro

Rohde & Schwarz was first to offer modular and flexible test solutions that cover all aspects of 4G testing. Powerful signal generators and signal and spectrum analyzers thoroughly test the transmitters and receivers used in base stations and wireless devices and perform measurements on components and power amplifiers.

Unique test solutions for MIMO, including a complete one-box test solution, support all key MIMO modes with channel simulation. From RF to end-to-end data, powerful communications testers support all protocol layers to fully test the air interface of wireless devices. Based on a scalable platform, the testers can be adapted to cover any test application need in all phases of development, verification and production. Scalable RF test systems reliably cover the verification and conformance test requirements of global certification bodies.
