Is WiFi half or full-duplex?
WiFi is a half duplex form of data transmission, which is to say, data packets are sent back and forth in sequence. It happens so quickly that it mimics seamless, two-way data transmission, but in fact, data cannot be both sent and received simultaneously.

Is half-duplex still used?
half-duplex – a port can send data only when it is not receiving data. In other words, it cannot send and receive data at the same time. Network hubs run in half-duplex mode in order to prevent collisions. Since hubs are rare in modern LANs, the half-duplex system is not widely used in Ethernet networks anymore.
Are all cell phones full duplex?
