Question 1

How do I know which LTE / 5G bands a country uses?

Accepted Answer

Select the country in the tool. It lists the 3GPP LTE (4G) and 5G NR bands each operational mobile network operator has deployed there, with band numbers (e.g. B3, n78) and their MHz — plus legacy GSM (2G) and UMTS (3G) — so you can specify a module band variant that covers that market.

Question 2

Why does the same 700 MHz frequency have different band numbers?

Accepted Answer

Spectrum is auctioned nationally, so the same frequency became different 3GPP band numbers by region. 700 MHz is a single harmonised band B28 across Europe, India, Latin America and Australia, but the US and Canada split it into carrier-specific bands — B12 (T-Mobile), B13 (Verizon) and B17 (AT&T).

Question 3

What are the most widely deployed LTE and 5G bands worldwide?

Accepted Answer

B3 (1800 MHz) is the most widely deployed LTE band, followed by B20 (800), B7 (2600), B1 (2100) and B28 (700 APT). For 5G NR, n78 (3500 MHz C-band) is the global mid-band. A gateway covering B1, B3, B5, B7, B8, B20, B28, B40 plus n78 reaches most operators outside North America, where the FCC band plan (B2/B4/B12/B13/B17/B66/B71) applies instead.

Question 4

Which bands does a 4G/5G IoT gateway need for India?

Accepted Answer

Indian operators have deployed LTE bands B1, B3, B5, B8, B40 and B41, plus 5G NR n28 (700 APT, Jio) and n78 (3500 C-band). A module covering that set works across the Jio, Airtel, Vi and BSNL networks in India.
