CETC Instruments launched the Ceyear 5252D multi-channel base station tester for the 5G base station test, covering 5G millimeter-wave band, with bandwidths of 200MHz, 500MHz, and expandable 2GHz. The maximum RF band supports 32 × 32 transceivers and the micro band supports 4 × 4 transceivers. The overall R & D process of 5G has entered the key stage of technical standard formulation and R & D industrialization. A major challenge for 5G researchers is that there are too many waveforms, frequencies, and bandwidths in the research of 5G base station, so it is urgent to have hardware platforms for development, verification, and experiment of 5g key technologies with multi-band, large bandwidth, and multi-channel.
The latest Ceyear 5252D 5G Multichannel Base Station Tester includes a high-performance multichannel RF microwave transceiver and a high-speed baseband processing extension, featuring wide frequency band coverage, large modulation bandwidth, many channels, and flexible configuration. 5252D is an ideal test and verification platform for 5G base station test and other new technologies of 5G system, which focuses on solving 5G key technical problems such as 5G large bandwidth, new subcarrier, frame structure, multiple access, waveform, modulation coding, multi-user simulation, etc. At the same time, the 5252D tester also supports 5GNR technology, providing wireless device designers and manufacturers with rich advanced functions, including:
High frequency to microwave millimeter wave coverage:
The 5252D covers four frequency bands, i.e. RF 400 MHz-6 GHz (100MHz) and microwave 24.25 GHz - 30GHz, 37 GHz - 43.5 GHz, and 66 GHz - 76 GHz covering most of 5g frequency range.
Large bandwidth modulation of 5g signal:
The radio frequency band bandwidth of the 5252D 5G multichannel base station tester is not less than 200MHz, the microwave band bandwidth is not less than 500MHz, and the modulation bandwidth can be extended to 2GHz, meeting the bandwidth requirements of 5g system at this stage.
Large scale MIMO flexible configuration:
The 5252D 5G multichannel base station tester can flexibly set up a multichannel receiving and transmitting system. The RF section supports 32x32 transceivers at most, and the microwave section supports 4x4 transceivers. The 64x64 and 128x128 transceivers are completed in a cascade manner, meeting the 5G channel number requirements for large-scale MIMO.
Test and verification of key technologies of 5G base station
The 5252D 5G multichannel base station tester supports waveform design such as F-OFDM / UFMC/ FBMC, modulation codings such as polarization code / multiple LDPC, millimeter-wave channel model design of ITU / 3GPP, baseband physical layer implementation design of 3GPP R15, and other 5G key technology verification.
5g system simulation and verification platform
The 5252D 5G multichannel base station tester supports 5G system simulation hardware verification, 5G channel environment simulation technology verification, 5G scene simulation technology verification, 5G system semi-physical simulation verification, and other 5g system technology simulation verification.
Focusing on the test innovation of the communication industry for a long time, Ceyear can provide both 3G / 4G / 5G protocol development and high-performance millimeter-wave platform, realize the perfect integration of a number of 5G technology solutions and mature microwave millimeter wave platform, and promote customers to enter 5G.
