2G and 3G modules support applications relying on the second and third generation of cellular networks – 2G modules support data rates of up to 85.6Kbps, while 3G modules support data rates of up to 7.2Mbps.

While these older technologies are reaching the ends of their lifespans and much is now said of their global sunsetting, the reality is still that 2G and 3G remain in widespread use globally, especially in markets where final sunset dates are well into the second half of this decade. Quectel therefore continues to offer our customers the modules they need to support applications relying on these technologies, as well as support and advice for migrating to the appropriate upgrades in preparation for final sunsets, most notably to LTE Cat 1, LTE Cat 1 Bis and LTE 450.
