Equipment introduction
At the end of 2019, the US Keysight E7515B 5G communication tester was introduced, which can be used for RF testing of NR , NR CA , LTE ( QPSK , 16QAM , 64QAM , 256QAM modulation), LTE CA , and can also help customers perform physical layer verification, conformance testing, throughput quantity test.
The 5G communication laboratory has 1 set of NR test systems, 2 sets of LTE test systems, and 2 sets of WCDMA test systems, which can conduct large-scale automated tests, greatly save time and cost, and have excellent accuracy and efficiency.
In today's era of winning the market by quality, STS will adhere to the high-end strategic positioning, continuously improve laboratory capabilities and expand service networks, continue to improve and surpass, and strive to become an excellent and impartial institution in the field of testing , and to ensure the quality and safety of products of various enterprises. Provide guarantees to escort customers' products to enter the market and participate in global competition.
5G frequency bands and their standards and considerations
5G frequency band is divided into 2 parts
FR1 （sub-6G ）
FR2 (mmWave)
5G countries currently use frequency bands
Several major 5G use countries
Differences from 4G and 5G NR and mmwave differences
Differences in test methods
Sub 6G test differences: basically similar to traditional 2G 3G 4G methods
mmWave test differences : SAR and RF need to be tested using an OTA method
