Eesti Energia‘s data division Televõrk introduced a new country-wide Internet service called KÕU (“Thunder” in English).

It’s based on 450 MHz CDMA2000 1xEV-DO. Max 2 Mbps down, 144 Kbps up.
Network hardware is provided by Chinese ZTE Corporation. The main end-user device is MG478, which is a matchbox-sized USB device with an external antenna option.
It works under Linux but any on-line information is hard to find. Here are my notes.
