In 3G and 4G mobile technologies, the character ‘G’ stands for:

Concept: Mobile network standards are labelled by ‘Generation’ — each numbered G (1G, 2G, 3G, 4G, 5G) marks a distinct evolutionary stage of cellular technology, standardised by bodies such as the ITU and 3GPP, each stage defined by a new radio-access technology and a step-change in data capability.

Application: 3G (third generation) introduced mobile broadband internet through UMTS/HSPA-class standards, and 4G (fourth generation) introduced LTE/LTE-Advanced, delivering all-IP high-speed data. In both ‘3G’ and ‘4G’, the character ‘G’ is short for ‘Generation’ — it is the generation-count marker attached to the numeral, not an abbreviation of any specific protocol, service, or brand.

Cross-check: The same suffix is used consistently across the whole generation sequence, which confirms the reading:

• 1G — analog voice-only cellular service

• 2G — digital voice plus SMS/text messaging

• 3G — mobile broadband internet access

• 4G — all-IP, high-speed LTE-class broadband

• 5G — ultra-low-latency, massive device connectivity

Every step in this sequence uses ‘Generation’ as the suffix’s meaning, which is inconsistent with reading ‘G’ as GPRS (a specific 2G/2.5G-era packet-data add-on), Grid (an unrelated distributed-computing paradigm), or Google (a company name) — none of these fit the numbered-generation pattern that spans 1G through 5G. Hence, ‘G’ stands for Generation.
