1G networks were the first form of cellular network to be widely used, having been implemented in the early 1980s.
1G networks are analogue cellular networks that transmit voice signals over radio waves using frequency modulation (FM).
1G networks use towers to divide service areas into small cells, offering better coverage and support for more users than typical cellular towers.
It is analog technology for transmitting voice signals over radio waves, despite being simpler but less efficient & more susceptible to interference.
When switching phones, mobile phone users can easily transfer calls between cell towers without disrupting the call.
1G networks have modest data speeds, poor audio quality, few security measures, and are prone to call drops.
