T-Mobile deploying LTE-U on its network

T-Mobile has started deploying LTE-U technology on its LTE network in the US, following the FCC’s certification of equipment from Ericsson and Nokia.

Is this the same 5Ghz used by WiFi and will interfere with hot spots?

What phones, if any, supports this?

Snapdragon 835 chipset has the modem that supports it.

Older but:

As discussed in this report, there is evidence that LTE-U systems can impair or shut down Wi-Fi in a wide range of common scenarios in local government operations, because LTE-U often does not sense Wi‐Fi devices. When an LTE‐U system does sense Wi-Fi devices, it is designed to transmit with an on‐off duty cycle rather than wait for silence—so it essentially talks over the Wi-Fi devices.
(See Section 3.1.3for more detail.)
Even when an LTE-U system is programmed to wait (e.g., the LAA variant, which is planned for environments where LBT is required by regulation), it waits for a much shorter amount of time than a Wi‐Fi system. Collectively, these attributes mean that both LTE-U in its current form and LAA can dominate the unlicensed spectrum rather than share it with Wi-Fi.
