including the type of connection and the quality of signal. For wired connections, such as ethernet cables, the maximum distance typically ranges from 100 to 300 meters. Wireless uplink connections can have a range of up to several kilometers, depending on the frequency and power of the signal...
Amplification and uplink transmission.The signal is sent on an uplink frequency from the ground station to the satellite. Because it travels long distances between satellites and ground stations, the signal must be amplified or boosted. That way the uplink message arrives at the satellite with en...

By introducing technologies such as uplink MU-MIMO, orthogonal frequency division multiple access (OFDMA), and 1024-QAM high-order coding, 802.11ax is designed to resolve network capacity and transmission efficiency problems from aspects such as spectrum resource utilization and multi-user access. ...
Wi-Fi 6 introduces various new technologies, such asorthogonal frequency division multiple access(OFDMA), uplink/downlink multi-usermultiple-input multiple-output(UL/DLMU-MIMO), BSS coloring, and Target Wake Time, significantly improving performance. In this manner, Wi-Fi 6 supports four times high...
