Dual-band Wi-Fi 6 and Bluetooth 5.0 are built in, so the T73W can be placed wherever there is power and wireless coverage, while dual Gigabit Ethernet ports with PoE, a USB 2.0 port and support for up to three colour-screen expansion modules cover wired desks.

A Trusted Execution Environment (TEE) hardware encryption solution, TLS 1.3, SRTP, 802.1X and WPA3 protect the device, the network and every call.
