1G
(First Generation) – Analog Voice (1980s)
- Launched in the late 1970s/early 1980s, 1G enabled
analog voice calls.

coverage.
- Example: Motorola DynaTAC 8000X[1][7][9].
2G
(Second Generation) – Digital Voice & SMS (1990s)
- Introduced digital transmission, improving voice
quality and security.
- Enabled SMS (text messaging) and basic data services.
- Standards: GSM, CDMA.
- Example: Nokia.
**2.5G & 2.75G – GPRS & EDGE (Late 1990s–2000s)**
- GPRS (2.5G) and EDGE (2.75G) increased data speeds,
enabling basic mobile internet and MMS.
3G
(Third Generation) – Mobile Internet (2000s)
- Brought faster data speeds (video calls, mobile
internet, email).
- Standards: UMTS, HSPA.
- Enabled the rise of smartphones.
- Example: Apple iPhone (2007).
4G (Fourth Generation) – Broadband Speeds (2010s)
- Introduced LTE technology, offering broadband-like
speeds for HD video, gaming, and seamless internet.
- Enabled mobile apps, streaming, and cloud services.
- Example: Samsung Galaxy S series.
5G
(Fifth Generation) – Ultra-Fast, Low Latency (2019–present)
- Launched commercially in 2019.
- Offers ultra-fast speeds, low latency, supports IoT,
smart cities, autonomous vehicles.
- Example: Samsung Galaxy S10 5G, iPhone 12 5G.
- Expected around 2030, aims for even higher speeds, AI
integration, and advanced connectivity, but not yet commercially available.This
summary traces mobile technology from 1G’s analog calls to 5G’s ultra-fast
connectivity, highlighting each generation’s main innovation and impact on
daily life.
