B26 · 850 Extended Cellular
B26 is a 3GPP LTE (4G) band (850 Extended Cellular), FDD duplex, uplink 814–849 MHz and downlink 859–894 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, 2 use it (Japan).12

What it means for IoT devices
- For IoT devices headed to Japan, support B26: it is a coverage layer, and without it indoor and rural signal drops noticeably.
Our dongles (MF833V, Dongle 400, F40) do not support B26.
