1g 2g 3g 4g 5g frequency bands

Each generation of mobile networks (1G, 2G, 3G, 4G, and 5G) operates on different frequency bands. Here are the typical frequency bands associated with each generation:

1. 1G (First Generation):
   • Frequency Bands: 800 MHz, 900 MHz, 1800 MHz
2. 2G (Second Generation):
   • GSM (Global System for Mobile Communications)
     • Frequency Bands: 850 MHz, 900 MHz, 1800 MHz, 1900 MHz
   • CDMA (Code Division Multiple Access)
     • Frequency Bands: 800 MHz, 1900 MHz
3. 3G (Third Generation):
   • UMTS (Universal Mobile Telecommunications System)
     • Frequency Bands: 850 MHz, 900 MHz, 1700 MHz, 1900 MHz, 2100 MHz
   • CDMA2000
     • Frequency Bands: 450 MHz, 700 MHz, 800 MHz, 1900 MHz
4. 4G (Fourth Generation):
   • LTE (Long-Term Evolution)
     • Frequency Bands: 700 MHz, 800 MHz, 850 MHz, 1800 MHz, 1900 MHz, 2100 MHz, 2300 MHz, 2500 MHz, 2600 MHz
5. 5G (Fifth Generation):
   • Frequency Bands: The frequency bands for 5G are more diverse and include both sub-6 GHz and millimeter-wave (mmWave) bands.
     • Sub-6 GHz bands: 600 MHz, 700 MHz, 850 MHz, 900 MHz, 1800 MHz, 2100 MHz, 2500 MHz, 3500 MHz
     • mmWave bands: 24 GHz, 28 GHz, 39 GHz

It's important to note that specific frequency bands can vary by region and country. Different bands are allocated for different purposes, and regulatory bodies allocate these bands to mobile operators based on licensing agreements. The move to higher frequencies, especially in the millimeter-wave range, is a notable feature of 5G, allowing for increased data rates and network capacity.
