Bluetooth BT test knowledge one: the configuration instructions of the Bluetooth channel number

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.

WiFi Test Tips 15: Introduction to Composite MIMO Connection

Composite MIMO is one of the three current mainstream WLAN MIMO test solutions.

Wi-Fi Test Tips 16: Introduction to Switched MIMO Connection

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.

Wi-Fi Test Tips Eighteen: Introduction to CCDF

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.

Wi-Fi Test Tips Nineteen: Basic Knowledge of 802.11b (1)

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.

Wi-Fi Test Tips 12: What is the difference and impact between long GI and short GI

Short GI (Guard Interval) is an improvement made by 802.11n for 802.11a/g. When the RF chip uses OFDM modulation to send data, the entire frame is divided into different data blocks for transmission. For the reliability of data transmission
