B12 · 700 Lower SMH (a)
B12 is a 3GPP LTE (4G) band (700 Lower SMH (a)), FDD duplex, uplink 699–716 MHz and downlink 729–746 MHz. The whole band sits below 1 GHz, so it is a coverage layer: it travels far and gets through walls, deciding rural and indoor signal. Of the 155 networks we check, 5 use it (United States, Canada).12
