Russia-based Yota Device's Ruby is an LTE hotspot device with a small E Ink display that shows the battery life and the status of the device: signal value, number of connected devices and the devices' mode - it can act as a secure or public-access point. The device supports LTE, HSPA+ and EDGE for the European market, and it has a configurable hardware radio for other bands.

The Ruby will launch in Russia in June 2013 for about $120, and will come to other countries in Europe later on.
