According to the Bluetooth protocol version specifications of different DUTs, from BasicRate (BR) of BT 1.0 to Enhanced Data Rate (EDR) of BT 2.0 to Low Energy (LE) that began to appear in BT 4.0. The Bluetooth Special Interest Group (SIG) maintains the core Bluetooth specifications and has been looking for expansion and balance on power consumption, speed, and the latest Internet of Things functions.
Composite MIMO is one of the three current mainstream WLAN MIMO test solutions.
Switched MIMO is currently one of the three mainstream WLAN test solutions. Compared with the other two MIMO test methods, Switched MIMO requires the DUT to continuously transmit the same signal during the test.
CCDF is the abbreviation of Complementary Cumulative Distribution Function. It is defined as the probability that the peak-to-average value exceeds a certain threshold in a multi-carrier transmission system. It also refers to a statistical method characterized by the peak power value of the digital modulation signal.
In the early years, the development of wireless local area network was slow, and it was difficult to promote and apply it, mainly due to the low transmission rate, high cost, limited product series, and incompatible products of many products.
True MIMO is one of the current mainstream WLAN three MIMO test schemes. True MOMO supports both TX and RX tests of DUT, and can complete all index tests of TX and RX.
