3GPP
The global body that writes mobile network standards: GSM, 4G LTE, LTE-M, NB-IoT and 5G.
3GPP brings together mobile operators, network equipment makers and chipset vendors. The technologies it standardises work across operators and countries, with roaming and many competing suppliers.
Why it matters for business
Choosing a 3GPP (cellular) technology gives you standard SIMs, roaming and modules from many vendors. Proprietary technologies depend more on one company or ecosystem.
